What is TDQ in CICS?
Transient Data Queues (TDQs) that the region requires are set up when the region and file manager are set up. Queue services describes how to you can use the CICS® Application Programming Interface (API) to queue data for subsequent internal or external processing.
What is TDQ in mainframe?
Transient data queues are used to store the data for subsequent internal or external processing. Data specified in the application program can be routed to or from predefined symbolic intrapartition or extra partition transient data queues.
What is TSQ and TDQ and explain the difference?
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.
What is the use of TSQ and TDQ?
– TSQ cannot started automatically a CICS transaction. Transient Data Queqe (TDQ): – Temporary Data Queues can be read only once. – Records in TDQ can be read only sequentially.
How is TDQ defined?
Transient data queues are extra partition if the data is directed to a external destination to the CICS region. Extra partition destinations are queues that are residing on any file system. Extra partition TDQ is not read destructive. Data accessible to application programs on any CICS region.
Which is the command used to browse TSQ?
– CICS-supplied Temporary Storage Browse transaction. – It displays the content of Temporary Storage Queue (TSQ).
How do I read TSQ in CICS?
A record within a TSQ is identified by the relative position known as the item number. The records in TSQ, remains accessible until the entire TSQ is explicitly deleted. The records in TSQ can be read sequentially or directly. TSQs may be written in the main storage or the auxiliary storage in the DASD.
Where a TDQ should be defined?
The transient data queue is to be associated with the specified system identifier. The system must be defined to the local CICS® system using an RDO CONNECTION definition. Specifying ATIFACILITY(SYSTEM) initiates a distributed transaction processing (DTP) session.J
What is TDQ and TSQ?
– TSQ cannot started automatically a CICS transaction. Transient Data Queqe (TDQ): – Temporary Data Queues can be read only once. – Records in TDQ can be read only sequentially. – A record in a TDQ cannot be updated.
Can we check the contents of a TSQ in CICS?
If you place the cursor against a specific entry in the expanded list and type a B (uppercase or lowercase), CICS invokes a direct link to the program DFHEDFBR used by the CEBR transaction to enable you to browse the contents of this TS queue. See CEBR – temporary storage browse for details.
