| One or more Central Processing Complexes (CPC), each with one or more programs being executed, become command initiators by issuing commands requesting an action to be performed by a command responder. The responder is a Structured Electronic Storage (SES) which comprises a coupling facility. The SES receives commands to be executed over a plurality of links interconnecting the CPC's and SES, and returns a response to the program that issued the command. The SES is the focal point for the CPC's to share data, control locks, and manipulate lists or queues. This couples the autonomous CPC's into a System Complex (Sysplex) displaying a single system image. An indicator associated with each of the links is set by SES when it appears to a initiator that problems on the link exist. The set state of any indicator prevents SES from starting execution of any subsequent commands. This preserves the orderly, sequential execution of commands to insure consistent states of data in SES, and allows the program that issued the command to determine exactly how the command ended at SES. Data associated with execution of the command is stored in a status save area of SES for subsequent access by the program. | ||||||
| 23 | Method for recovering data base from fault in shared storage in system sharing plural computer data | JP26919992 | 1992-09-14 | JPH05225019A | 1993-09-03 | CHIYANDORASUKARAN MOHAN; INDAAPARU ESU NARANGU; JIEIMUSU ZUII TENGU |
| PURPOSE: To efficiently and quickly recover data from a fault generated in a shared storage in a shared system for plural computer data. CONSTITUTION: A data base system writes an updated page in a high speed shared electronic storage 16 and another data base system acquires the page written in the shared storage 16 to change it without writing it in a permanence storing area 22 at first, but the page is written in the area 22 by cast-out processing. In the case of recovering a data base from a fault generated in the shared storage 16 at the time of supplying a transaction log in the data base system to a shared body, a boundary is determined by discriminating a recovery boundary for setting up a point detecting a changed log record for the page stored in the storage 16 and the log record is supplied to a page version obtained from the storing area 22 to recover the data base from the fault. | ||||||

| PROBLEM TO BE SOLVED: To continue transaction processing without losing conformity in data, even when a fault occurs in a server before the transaction which processes data is committed in the server among a plurality of servers, in response to a request from a client.SOLUTION: A transaction log storage unit 15 in a client 10 stores an SQL statement issued to a server 20 in association with a transaction ID. When a fault occurs in the server 20, an SQL processing unit 14 in the client 10 sequentially reads SQL statements stored in the transaction log storage unit 15 in association with the transaction ID and reissues an SQL statement using the same transaction ID, and an SQL processing unit 24 in the server 20 processes the reissued SQL statement with the transaction ID, while keeping lock information corresponding to the transaction ID. | ||||||

| Apparatus and method insuring that data objects used to maintain state information for shared data at a local central processing complex (CPC) is coherent with respect to state information maintained at a structured external storage facility (SES) over a link is valid. An error detector is attached to the CPC side of the link for detecting errors on the link, and, when an error is detected, setting a error state pending (ESP) latch to indicate that the link has failed and that the shared data in the local data object may be invalid because a message invalidating the data may not have been received by the CPC. In data processing operations, the ESP latch is interrogated by a central processor in the CPC to determine the health of the message path to the SES facility. A local cache vector reflecting the validity of the shared data in the local cache may then be interrogated to determine if the shared data in the local cache is valid. If a healthy path has continuously existed and the vector indicates that the local cache data is valid, the integrity of the data can be relied on. <IMAGE> | ||||||

| PURPOSE: To recover the error of a process designated as a master process for one of shared resources at least at a distributed computer system. CONSTITUTION: The error of the master process is detected by one or more hidden processes. This error detecting hidden process performs a test for determining whether the error detecting hidden process holds a write lock managed by the master process or not. When the error detecting hidden process is held in that node, the relevant error detecting hidden process becomes the master. When the write lock is not held, the error detecting process determines which process has the write lock from a shared resource control file and transfers a request for succeeding the responsibility of the master process to the process holding the write lock. | ||||||

| Apparatus and method for reading data pages 33 in a transaction processing system 20 without locking the pages are disclosed. The system maintains a Global_Committed_LSN 36 identifying the oldest uncommitted transaction accessing any of the data, and Object_Committed_LSNs 38a,38b identifying the oldest uncommitted transactions accessing particular files, tables and indexes. Each data page includes a Page_LSN 35 identifying the last transaction to have updated the page. To read a page, a transaction first latches the pages, and compares the page s Page_LSN with the Global_Committed_LSN, or with the page's respective Object_Committed_LSN. If the Page_LSN is older than the Committed_LSN with which is was compared, then the transaction reads the page without locking it, since there can be no uncommitted transaction in process which might have updated the page's data. However if the Page_LSN is younger than the Committed_LSN, the page is locked before being read. <IMAGE> | ||||||

| PURPOSE: To keep consistency between a data structure and a control structure in a connection facility at the time of the existence of a true or apparent error in a link forming the mutual connection. CONSTITUTION: This data processing system is provided with a command responder 10, a command initiator 11, and a program sequencing means. The command responder 10 includes a program control command execution means, a control storage means including a command state storage area, and a data storage means. The command initiator communicates commands, which request actions to be executed by the command execution means and return of responses generated by these actions, with the command responder and sends a first command to the command responder to identify and reserve a part of the command state storage area. The program sequencing means selectively specifies a part, which is reserved in accordance with a second command from the command initiator 11, to store state information related to the second command. | ||||||

| PURPOSE: To provide a device and a method for guaranteeing that a data object used for maintaining the state information of shared data in a local central processing complex(CPC) is coherent to the state information maintained in a structured external storage(SES) mechanism through a link. CONSTITUTION: An error detector for detecting an error on the link and indicating that the link generates a fault and it is possible that the data are invalid since a message for invalidating the shared data inside a local data object is not received by CPCs 10A-10N by setting an error state pending(ESP) latch when the error is detected is added to the CPC side of the link. At the time of a data processing operation, a central processing mechanism inside the CPCs 10A-10N inquires the ESP latch and judges whether or not the message to the SES mechanism 16 is healthy. | ||||||
