Q14. What Are The Differences Between Temporary Storage Queue (tsq) And Trient Data Quene (tdq)?

Temporary Storage Queue names are dynamically defined within the application application, at the same time as TDQs must first be described in the DCT (Destination Control Table). When a TDQ carries sure quantity of data (Trigger degree), A CICS traction can be started out mechanically. This does not appear whilst the usage of a TSQ. TDQ (extra partition) may be utilized by batch utility; TSQ can't be accessed in batch. The Trient Data Queue is truely a QSAM document. You can also replace an current object in a TSQ. A document in a TDQ can not be updated. Records in TSQ can be read randomly. The TDQ may be read most effective sequentially. Records inTemporary Storage can be examine more than as soon as, while recordes stored in Temporary Data Queues cannot. With TDQs it's far "one read" handiest.

READQ TD, the read is destructive.

Q18. In An On-line Environment, How Can You Prevent More Than One User From Accessing The Same Trient Data Queue At The Same Time?

By issuing an EXEC CICS ENQ against the aid. When processing is finished, a DEQ must be performed.

Q19. What Is The Cics Command That Is Used For Reading A Record From The Tdq?

READQ

Q20. What Is Multitasking And Multithreading?

Multitasking is the feature supported with the aid of the running system to execute more than one challenge concurrently. Multithreading is the system surroundings wherein the tasks are sharing the equal applications load module under the multitasking surroundings. It is a subset of multitasking since it concerns assignment which use the same software.

Q21. Can You Access Esds Files From Cics?

Yes

Q22. What Is The Differences Between Getting The System Time With Eibtime And Asktime Command?

The ASKTIME command is used to request the modern date and time. Whereas, the EIBTIME field have the value at the project initiation time.

No, No, Yes.

Q24. How Do You Execute A Background Cics Txn ?

With a START or ATI.

Q25. Do You Receive The Attribute Byte In The Symbolic Map?

On EOF sure.

Q26. Which Cics System Program Is Responsible For Handling Automatic Task Initialization?

The Trient Data Program (TDP).

Q27. What Do You Do If You Do Not Want Characters Entered By The User To Be Folded To Uppercase ?

Use ASIS alternative on RECEIVE.

Q28. How Do You Read From A Tsq?

Temp storage read command

Q29. What Does Eib Mean?

The EIB is the EXECUTIVE INTERFACE BLOCK. It isn't always the EXECUTE INTERFACE BLOCK. All TP video display units or traction processor are recognise as EXECUTIVEs as they carry out manner on behalf of a application module. CICS and DB2 are executives.

Q30. Sync Points Cannot Be Requested By The Application Programs (actual Or False)?

False

Q31. What Is A Two Phase Commit In Cics?

This takes place whilst a programmer Issues a EXEC CICS Syncpoint command. This is called two section due to the fact CICS will first commit modifications to the sources beneath its manipulate like VSAM files, and the DB2 adjustments are dedicated. Usually CICS signal DB2 to finish the next section and release all of the locks.

Q32. In Which Cics Table Would You Specify The Length Of The Task Work Area (twa)?

In the Program Control Table (PCT).

Q33. Into Which Table Is The Terminal Id Registered?

TCT.

Q34. Suppose Pgm A Passes 30 Bytes To Pgm B Thru Commarea And Pgm B Has Defined Its Dfhcommarea To Be 50 Bytes . Is There A Problem ?

Yes, if B tries to get right of entry to bytes 31-50.

Q35. What Is Mdt? What Are Fset, Frset ?

Yes.

Q42. Db2 What Is The Difference Between A Package And A Plan. How Does One Bind 2 Versions Of A Cics Traction With The Same Module Name In Two Different Cics Regions That Share The Same Db2 Subsystem?

Package and plan are typically used synonymously, as on this website. Both incorporate optimized code for SQL statements - a bundle for a single program, module or subroutine contained inside the database request module (DBRM) library. A plan may comprise multiple applications and suggestions to bundle that could be referenced in  specific pl.
