Description

The interrupt system and the method that comprise user interface

The present invention relates to single and a plurality of processor computer system, this system provides system service for the requestor unit that moves in this system.More at large, the present invention relates to enlarge or revise the method for the selected program element that pre-exists institute runtime operation.

For many years, computer system develops into various forms of a plurality of processor systems from single isolated processor.Many computer system service routines unit just abbreviates it as " program " sometimes.

Program element comprises computer instruction, and computer system is carried out these instructions to finish specific function.These program elements can be produced by other program element.Yet in most of the cases, people are devoted to produce executable computer instruction set always to a certain extent.

Program element, when being performed, the requirement of certain known or imagination is satisfied in expection.In any case great majority program element design in the past or that now just designing can not be fit to all requirements in the future.

Prior art systems is near handling the needs of demand in the future in many ways flexibly.In many cases, former method is impracticable and/or do not allow the user that plurality of optional is arranged in the process of implementation on cost.

The development and the combination of new hardware system, new operating system, new procedures unit, new systematic procedure, new data structure or new user interface can require original program element to be corrected, recompilate, or worse situation, owing to problems such as relevant compatibility and/or cost go out of use.Some art methods requires in the application of this method and carries out and train widely.The certain user possibly can't bear art methods is wanted the time spent in order to finish, money and human resources.

Requirement to the dirigibility aspect of the renewal of existing program or correction is obvious especially in the multiprocessor compartment system.Several dissimilar problems provide motive power for the development of ordering about multi-user's processor system.

One of them motive power is more effectively to share the hope of information between several users.A method of head it off is that each processor is linked together by this area network, and these processors can be identical, also can be different.This network can make many different individuals and relevant common information and the access mutually of processor access thereof.

Another motive power of impelling the development of multi-user's processor environment is to create the hope of the computer system of high-reliability with low fiduciary level element.This type systematic typically is used in such as environment such as bank, issued transaction or tank farm stock controls, and wherein fiduciary level is primary.

One of this type of computer system family is the California, and the Tandem company of Cupertino sells.The Tandem system can be with single isolated, a plurality of processor structure, or moves as a plurality of inner joint forms that connect.Each node is corresponding to one or more multicomputer systems.

Support the master routine system of a plurality of remote transaction terminals or tank farm stock control function, it may comprise tens program elements, in multi-processor environment, it is very difficult and expensive that the place that is mounted on production basis and moves, the solution of above-mentioned renewal and maintenance program unit problem become.For example, new operating system may be adopted by the hardware seller.In this example, the Systems Operator may have to load onto new operating system, safeguards to receive lasting support and operating system.

If the change of operating system is opaque for existing programming system, these programming systems need be corrected or recompilate so.This processing is not only expensive and time-consuming, and can lead to errors in a plurality of processor environment in a plurality of programs, may cause catastrophic results thus.

In addition, the user who obtains software from the third party sellers may be for not revising, and expands or recompilate necessary source code or file, and worse situation is that the third party sellers no longer continue as user's support mostly or new release is provided.

Like this, when requiring or during environment change, need just to continue and to upgrade safely or revise existing program with effective cost form.First-selected ground, this needs can be satisfied by the individual of system operation, and do not need to get back to original software marketing person or remove to revise the program element that is originally provided.

In addition, in a plurality of processor systems, operating environment changes continuously.As a result, resource, available processor with when a program element or the each initialization of process can with fellow's mixing will be different, this depend on other program element or process at any given time in effective situation.

Like this, continual about resources allocation and managerial problem with regard to having, in these systems, they must be suggested.A kind of known method, by the application the assignee sold, name is called " the automatic network balanced system " that be used for the Tandem computing machine, provides resource allocation system and resource management under this environment based on predetermined and fixing distribution method.

In known automatic network balanced system, performance factor is to be used for considering to select to assign handle therein best or optimal processor, they comprise the available work on the availability of a given processor or busy state, available storer, exchange rate, delivery rate, storer queue length, the standby inventory, and many other amounts.Various performance factor can be used weighting system and carry out valuation.Then, show as only processor and can be used to working procedure.

Known load balance system is very successful, and can be used for improving greatly the performance that is similar to the Tandem system.Yet, select for use the optimal method of carrying out given task handling device that is assigned not consider that place or user are to diversity between a kind of setting and another kind of setting the or requirement customized.

Like this, just continue requirement and can consider the method more flexibly of the variation of different location.First-selected ground carries out so a kind of method and provide the place specific input for the processor selection process with permission, or expansion offers the service of the given process of carrying out.Best, implementation will be transparent for separately processing.

The present invention be directed to the apparatus and method of carrying out interruption working time for the computer instruction that pre-exists in the program element, so that support user's on-hook or enter the point that can be used under the situation that the user separates, revising and/or enlarging program element creation and/or that receive.As a result, program element can satisfy the present requirement of user, and can allow the user to be corrected as requested to support requirement in the future.After using the present invention, these just can be finished and not need the original author and/or the inventor's of interrupted program element support and/or guidance and/or special knowledge, perhaps also need not any other equipment actual electronics or machinery.

When program element requires the operating system of computer system to provide service for its operation, reach above result by the interrupt system service call that the executive routine unit sends in working time.Interruption can appear in the combination of master routine unit, user library program element, system librarian unit or program element listed above.

This method expects that also the interruption that system service is called and user's on-hook or inlet point can be positioned in several class methods unit.This just makes the user in the place of the interruption generation of system service request many options be arranged.Further, this allows the user according to the then program element execution the present invention of a program element, if this requirement is arranged, perhaps according to the then execution the present invention of system of a system.

According to one aspect of the present invention, a device and a kind of method are provided one or more steps of being used for changing or change in the method that pre-exists to carry out intended function.Place or user-defined step or function can be combined into process customization or special.

For example, this method can be used to Resources allocation in a plurality of processor computer system.In others of the present invention, also can finish the dissimilar function the function of appointment in the method for depositing earlier.

This method comprises the candidate's step that detects a change.The change process can comprise carrying out and be different from original desired function of this step or conversion or expand this step.

Before carrying out one or more predetermined changes or switch process, determine definition in the past, the user provides, and whether the step collection of pre-change is what will carry out.Respond this determining step, pre-change or pre-converted step group that place or user provide are performed as noted like that.

Then, this method comprises execution this one or more predetermined changes or switch process.According to one aspect of the present invention, these steps comprise determines that in a plurality of available resources which can be used to carry out the step as the requirement of the candidate of change.

Alternative ground, predetermined change step can be provided at the expanded functionality that can not call in original candidate's step.These expanded functionality may become desirable, as long as they are transparent for original candidate's step.

Then, this method has determined whether one or more in back change (post-alteration), the step that place or user supply with.Then, after carrying out change step collection, these steps can be performed as noted like that.

Still according to another aspect of the present invention, this method can be used as at a plurality of nodes, the purpose of Resources allocation in a plurality of processor systems.Each node can comprise one or more computer processors.These nodes can be replaced mutually practically, also can link together by communication line.

This respect comprises the following steps:

Carry out a succession of step in the prior defined procedure;

Detect a step carrying out in order, and this step is the candidate of changing;

The step that interruption is detected, and stipulate before determining, the user provides, and whether a pre-converted step collection exists;

Interrupt this order, and carry out the pre-converted step collection that the user provides, such as noted;

With candidate's step conversion is one or more predetermined predetermined sequences that are converted step;

Carry out after the switch process, definition before determining, whether user provide exists at back switch process collection;

Carry out that the user provides at back switch process collection, such as noted; And

After detecting step, turn back to sequence of steps at once, continue by this to handle.

Still in another aspect of the present invention, this method is used as the purpose of resources allocation, not only for the throughput of optimization process, also in order to generate redundant database, for example disaster recovery in isolated place automatically for other functional purpose.

These and other aspect of the present invention and feature will with reference to following accompanying drawing and the declaration order of following discuss.

Fig. 1 is the sketch of multinode, a plurality of processor network;

Fig. 2 is the sketch of the environment of executive routine unit therein;

Fig. 3 is the process flow diagram according to method of the present invention; And

Fig. 4 is the process flow diagram according to a replacement method of the present invention.

When the present invention is subject to many multi-form embodiment influences, certain embodiments will show in the accompanying drawings, and be described in detail at this, it will be appreciated that here the content that discloses be looked at as the principle of the invention for example, rather than limit the invention on the embodiment that institute illustrates in detail.

This method might be upgraded program user or Systems Operator and is revised the program that pre-exists and do not need to recompilate the source code of corresponding program unit.This finishes by selected calling program or about the referral procedure of process, program element or variable, and these programs can be inside or outside for the program element of the execution that pre-exists.A kind of interruptable instruction is the operating system service call.

When interrupting, operating system with routine library that the program element of just carrying out is connected in seek invoked procedure, if their exist.In the program element that lacks the relevant procedures storehouse or just carrying out during the pairing person of invoked procedure, operating system will attempt searching invoked procedure or program element in other system library so.

Find pairing person's place in routine library or in system library, this process or program element just are performed so.If pairing person not, should working time mistake indication turn back to the program element that calls.

It is available in separately storehouse process or program element that this method makes " user's on-hook ".Term " user's on-hook " refers to the inlet point or the step of intentional generation as employed herein, and wherein user or Systems Operator are in order to upgrade pellucidly or to revise performed program element and can insert one or more computer instructions (code block).Therefore, the user has bigger control to computer system, and can revise in the outside of the program element of carrying out or expand.This has just been avoided revising or recompilate any requirement of this program element.

Another advantage of this method is the situation that it can be used for routine library is combined into program element itself.User's on-hook provides a kind of mode, is user or operator and builds up a bridge between software package different editions or release and program element.

Fig. 1 illustrates a plurality of processor computer networks 10 with sketch form.Network 10 comprises a plurality of nodes, from 12 to 18.

In the node 12 to 18 each can comprise one or more computer systems.Representational example comprises a plurality of processor computer of Tandem type system, and it can comprise nearly 16 processor modules.

Will understand, a node, for example node 12, can the independently single processor computer of conduct system carry out.Restriction of the present invention is neither the number of processor and structure, and whether existence that neither telecommunication circuit.The present invention can advantageously be achieved in conjunction with single autonomous system.

In the node 12 to 18 each can be passed through communication channel, and for example channel 20a is to 20e, and a node with other communicates at least.Mat long haul communication circuit or other communication means interconnect node 12 to 18 or to the small part connection, network 10 can distribute on provincialism ground.

The program element 30 that Fig. 2 carries out in processor 32 with the sketch form explanation.Usually program element 30 is communicated by letter with processor 32 by operating system.Operating system 34 provides multiple service for performed program element.

Program element 30 and operating system 34 are stored in the one or more storage component parts or unit of processor 32 usually.Sort memory and operating system 34 begin the process of executive routine unit 30 in processor 32 details is known, is not restriction of the present invention.

As what know already, an aspect of operating system is the utilization ratio that enlarges processor 32, and improves creation facilities program (CFP), and for example program element 30, speed and simplification.In this respect, operating system 34 provides the multiple order of predesignating, and is referred to as " system service is called " (SSC), and when the program element request of calling, it carries out some functions of predesignating.

Representational system service is called and is comprised that implementation " reads " order of function.The request of " reading " based on the parameter of being given, can require to read from disc driver or from other type magnetic store, maybe can require to read from terminal or from other device.

Alternative ground, but the operating system system service call, for example " write " in memory cell or the device.The request " write " can send to communication line, printer or analog to data or program.GURDIAN(by Tandem escorts god) inventory widely of a type systematic service call of operating system support invests and shows among the A.

According to the present invention, between program element 30 and operating system 34, insert functional layer 36, it comprises that " user's on-hook " is inlet point.At these inlet points, operator, user or place can be expanded or revise the external reference program of being interrupted by operating system or call.

In case instruction is interrupted, then first user's on-hook is verified or carries out.This inlet point can comprise original code block that user or operator supply with.This original or " formerly " code block is will be performed before carrying out any correction or expanding function as the theme that is interrupted instruction.

Then, interrupted call or services request can be carried out as being required.This implementation as described below, can be corrected and/or enlarge in a predetermined manner, or expansion.

Then, second user's on-hook or inlet point can be verified or carry out, with determine whether any to be performed in back conversion, the user's or the place specific code.If have, then this sign indicating number is performed.At last, suitable parameter and/or data can be returned to the program element 30 that causes services request or call in the past.

According to the present invention, interrupt procedure is implemented in an embodiment of service rating system, and this social estate system is usually called by routine library and the operating system of system library between calling is forced.Call or the first step of functional request as implementation, if routine library 30a is related with program element 30, operating system 34 at first check program storehouse 30a with definite interrupted external reference program or be invoked in the routine library and whether exist.

The system service that mat offers operating system 34 to the copy among the routine library 30a call or function partly or entirely, before the request of operating system interrupt routine unit to this service, the respective process in the routine library (rather than system library) will be performed.This just provides the medium of revising or expand these requests in a predefined manner.

Therefore, 30a interrelates with library structure, and when program 30 was carried out special service call, a plurality of operating system services of calling that are corrected can be provided according to this request.In addition, almost be transparent according to the program element of carrying out, this service can be extended in the intended manner and/or be revised, or changes fully.And if when suitable parameter and/or data were returned to program element 30, then this program can continue to carry out later instruction.

Should be appreciated that routine library 30a does not need putting into practice this method.A kind of structure of equivalence can be finished in operating system 34, as will discussing later on, or finishes in program element 30 itself.

Example 1 has illustrated this process.The row indicated of the order 1 left hand margin of number following the usual practice is listed.

In example 1, according to almost being transparent in interface layer 36, the read operation in the program element 30 can be interrupted and/or revise or change.The row 40 of example 1 is defined as " reading " function that has relevant therewith several parameters to the process that will carry out.

The process of " reading " be expert at 42 the beginning.Row 44 is represented first user's on-hook or the inlet point.An invoked process comprises one or more specified place instructions specific or that the operator is specific in the past, and they are not the normal parts of " reading " process.Carry out after the process of row 44, " reading " process of vacuum can be performed, roughly pointing out in row 46.

Should be noted that the real readout that can be implemented can be the readout that is expanded and/or with the big different read procedure of original expectation and read procedure appointment in calling program unit 30.Like this, if be necessary, can between distinct program version and/or release, provide the bridge function.

40 PROC READ（1，2，…n）

42 BEGIN

44 CALL PRIOR（1，2，…n）

46 JUMP TO READ FUNCTION VIA O/S LOGICAL ADDRESS

48 CALL POST（1，2，…n）

50 END

PROC PRIOR（1，2，…n）

BEGIN is if need, and user instruction can insert this point

END

PROC POST（1，2，…n）

BEGIN is if need, and user instruction can insert this point

END

Example 1

Row 48 is second user's on-hook or inlet points.Invoked process comprises the instruction specific or that the operator is specific of one or more places, and they can be implemented after read out function is implemented again.The end of process is expert at and is pointed out in 50.

Will be understood that the position of user's on-hook, number or function are not restriction of the present invention.In addition, the present invention expects to use, for example, and the multilayer inlet point in program element, routine library or system library.

After the read procedure from example 1 turned back to program element 30, this program will if having, continue to carry out according to parameter that returns or data, and these parameters or data are given by wherein initial read procedure.Therefore, the actual information that offers program element 30 can from the diverse position and/or the sources of program element 30 original expectations, and this change can be transparent fully to this.

Fig. 3 has shown the process flow diagram of the embodiment of method of the present invention.The process of Fig. 3 will be explained as follows in conjunction with the text of example 1.In the embodiments of figure 3, routine library 30a had been connected to program element 30 in the past, and was available in working time.The graduate method of mentioning above the use, when program element 30 calls external function or service, when perhaps attempting to begin to carry out external procedure, operating system 34 is check program storehouse 30a at first.

Routine library 30a with corresponding to program 30, the process of some external reference program formerly is loaded at least.The name of the storehouse process of loading before some must be identical with the name that the system service that will expand and/or will revise is called.(usually, this is considered the mistake of carefully being avoided for need! )

In addition, must be able to obtain, normally by operating system, the logical address of the corresponding system service call in the operating system storehouse that will interrupt.Corresponding storehouse process need can not use its name just can call this information of this service function.

For example, in example 1, " reading " system service is called and will be interrupted and/or revise.As a result of, routine library comprises a PROC READ instruction.Be expert in 46,, must carry out a:JUMP TO LOGICAL ADDRESS OF SSC READ, call it oneself to avoid PROC READ in order in the operating system storehouse, to call real " reading ".

Referring to Fig. 3, program element is carried out by 30 former beginnings.Step 62 is represented executive routine 30, up to making certain external request, or finishes up to program element 30, and at this moment program terminates in step 64.

When program element 30 is made external request, for example request " reading " or " writing ", operating system 34, in step 68, at first whether check program storehouse 30a if any, finds in this storehouse to determine this function or process.If call function, process or external reference program are found by the operating system 34 of storehouse 30a, for example, " reading " program of example 1, then this process is just initial.

In step 72, run into first user's on-hook or the inlet point.This is corresponding to calling on the row 44 of example 1.If have operator's process specific or that the place is specific and/or sign indicating number, then these steps should be performed.This is corresponding to the program of carrying out on example 1 row 44.

In step 76, the system service of being called by program element 30 is called or other function is implemented, and this is corresponding to " reading " function of carrying out on example 1 row 46.The process that is performed of the operating system that is performed can be different from the process that the creator expected of program element 30.

In step 78, run into second or " in the back " user's on-hook or inlet point.This is corresponding to the process of carrying out example 1 row 48.Then, turn back to step 80, executive routine unit 30.When carrying out user's on-hook instruction, return path alternately, for example step 80a or step 80b can be provided by the user.

In this embodiment, if invoked procedure or services request are not found in routine library 30a, and if they are in system library, institute's requested service or process are implemented in step 70 so, and perhaps other of binding operation system 34 served and carried out.Parameter of any necessity and/or data turn back to program element 30, and in step 62a, this program element continues to carry out.

As can from the process of Fig. 3 see, as place pre-converted specific, that the user supplies with and/or revise step in advance, first user's on-hook, for example process 44, and in the back conversion or in back correction step, for example process 48, the result, original function that operator and/or user ask for program element provides expansion, conversion and/or revises is quite easy.These are all in the outside of program element 30, and almost are transparent for program element.

Fig. 4 is the explanation that the present invention replaces embodiment.In the embodiment of Fig. 4, program element 30 not necessarily must have the routine library 30a relevant with it.

In any case the name that process in the operating system storehouse or system service are called is former to be changed, so that they and process or " system service is called " that will interrupt are distinguished.This change has been arranged, and real operating system is called and can be proceeded under new name.One of these processes can be corresponding to " opening " process.To renaming of the relevant system service program of system library, for example " open " renamed as " sopen ", step 34b as shown in Figure 4 can finish when operating system is compiled and links together.In addition, corresponding process, step 72a as shown in Figure 4 must be loaded in the system library with the original name that the system service that will interrupt is called.

Be corrected and expand if the corresponding system library process of operating system is former, as described above, then might carry out specific " prior " process of corresponding user, as example 1 row 44 is identified, in step 72a, the step of discussing before being similar to 72.After step 76a carries out corresponding and/or similar system service and calls, can in most of step 78a, be performed by the user-defined instruction of " post " process representative of example 1.Then, operating system 34 if having, turns back to program element 30 to suitable parameter and/or data, and program element continues to carry out in step 62a then.

The method of describing before using, the embodiment of Fig. 3 or the embodiment of Fig. 4 make user and/or operator's renewal, maintenance and/or revision program unit, and for example the unit 30, become possibility, so that tackle the environment of change and the function request of change the present and the future.Also might revise and/or the update system service call, so that the function that provides very different and/or enlarged, these functions were to offer corresponding program element in the past, and for example program element 30, and operating system 34.

Instruction described above is interrupted being implemented in working time, and almost is transparent for performed program element.The source code of program element does not need putting into practice this method.Mat makes " user's on-hook " or inlet point become available, as described above, carry out corresponding system service call before and afterwards, user and/or operator can more effectively administer and maintain, and upgrade their program element in the very practical mode of cost.Further, because this method almost is outside to separately program element, so third party sale person or the not influence of maintenance relation.

The other representative example of the mode that the method for Fig. 3 and/or Fig. 4 is used is included in the distribution of the resource of improving in a plurality of processor environment, is included as user's correction specific and/or that the operator is specific resource allocator is provided.When carrying out write-in functions so that a plurality of almost transparent data set to be provided, redundant write operation can be provided, and these data can be used to checking, disaster recovery functionality or fellow.

Like this, according to the present invention, according to almost being transparent, the program element that user interface can be used to revise by carrying out is the request that various purpose is done.This makeover process mainly occurs in the outside of program element.It can be mainly in the outside of relevant operating system, but the purpose in order to customize also can be revised by operator and/or user at an easy rate.

When just moving, the present invention discussing aspect program element internal conversion and/or the revision directive, for example in the program element 30 of demonstration.Will be understood that this method can be used together with any kind program element, for example use, utilization or fellow.Therefore, this method also be used to change and/or revision program in instruction, this program also can be looked at as a part of operating system routinely.

Will be understood that also the embodiment of Fig. 3 and/or Fig. 4 can be combined.In addition, alternately some routine library process and relevant master routine unit being merged mutually also is spirit of the present invention and intention.

Example 2 further describes method of the present invention with the source code form.

In sum, can see and under the condition of not violating spirit of the present invention and intention, can make many variations and correction.Also be appreciated that specific device, can expect that it is unconfined for this paper explanation, perhaps should deducibility it be unconfined.Of course it is contemplated that the claim that mat is additional, it is applicable to all these corrections that belong under the claim intention.
