What is TS queue in CICS?
Temporary storage is the primary CICS® facility for storing data that must be available to multiple transactions. Data items in temporary storage are kept in temporary storage queues.
What is transient data queue in CICS?
Transient data queues are extra partition if the data is directed to a external destination to the CICS region. Transient data queues must be defined and installed before referring them by an application program. If the TD keyword is omitted, the command is assumed to be for temporary storage.
What is TDQ and TSQ?
TDQs are read destructive.. as soon as read occurs on a record, that record will get deleted from TDQ. Whereas, in TSQ, program can read the records sequentailly (or) randomly. it wont delete records when read happened. 3 posts • Page 1 of 1.
How do I find my TSQ in CICS?
The INQUIRE TSQUEUE command returns information about temporary storage (TS) queues. The INQUIRE TSQUEUE command operates on all the temporary storage queues that exist in the CICS® region. Temporary storage queues that CICS creates internally for its own use, for example, queues used by BMS, are included.
What are transient or persistent queues?
The communication is done through asynchronous queues, which can be either transient or persistent. Transient queues are faster, but not reliable in the case of a system crash. Persistent queues, on the other hand are slower but reliable.
What are transient queues?
You can define transient data queues so that writing items to the queue causes a specific transaction to be initiated (for example, to process the queue). Temporary storage queues have nothing that corresponds to this trigger mechanism, although you can use a START command to perform a similar function.
What causes Asra in CICS?
ASRA abends CICS issues an ASRA abend code when it detects that a program check has occurred in a transaction. Program checks can occur for a wide variety of reasons, but you can find the nature of the error from the program interrupt code in the program status word (PSW).
What is BMS in CICS?
Basic mapping support (BMS) is an application programming interface between CICS® programs and terminal devices. Creating the map. BMS provides three assembler language macro instructions (macros) for defining maps. This method of map definition is still widely used, and this is the method that is described here.
What is a transient queue?
What is indirect destination in CICS?
*INDIRECT: Indicates an indirect destination; that is a logical destination that points to another destination, which is defined in the DCT as an internal, external, or remote destination.
What is Dfhmsd in CICS?
Description. A DFHMSD macro contains one or more map definition macros, each of which contains one or more field definition macros. It begins: mapset DFHMSD TYPE=MAP (or TYPE=DSECT) and ends: [mapset] DFHMSD TYPE=FINAL. mapset is the one- through seven-character name of the map set.
How do you resolve Asra?
To solve ASRA abend, first we need to identify where it actually occurs. To locate problem we can make use of debugging tools like Xpeditor, cedf. Most of the times even normal text send stmts would help us. Once we got the problem area, we would come to know the causes for the ASRA abend.
How do I resolve my CICS Abend?
How to resolve ‘CICS’ production abends in Mainframe
- Locate the correct dump in the dump listing.
- Note the abend code in the dump heading.
- For ASRA abends, determine the type of program check by looking at the last hex character of the third full word in the PSW.
How does the CICS Temporary storage queue work?
The CICS temporary storage domain can process multiple requests concurrently, but it serializes requests made for the same temporary storage queue, and the queue is locked for the duration of each request. You use TSMODEL resource definitions to set up models that CICS uses to create temporary storage queues.
What is TSQ queue in CICS?
Temporary Storage Queue. Temporary Storage Queue (TSQ) is a feature that is provided by the Temporary Storage Control Program (TSP). A TSQ is a queue of records that can be created, read and deleted by different tasks or programs in the same CICS region. A queue identifier is used to identify TSQ.
What is temporary storage queue in TSP?
Temporary Storage Queue. Temporary Storage Queue (TSQ) is a feature that is provided by the Temporary Storage Control Program (TSP). A TSQ is a queue of records that can be created, read and deleted by different tasks or programs in the same CICS region.
What does TSQ stand for?
