Configuration Restrictions

CICS Support

CICS is supported in a PAC with the following CICS resources restrictions:

CSA

The CSA trace flags are shared between regions in a PAC. csa-TCS-unique-generator and csa-ICE-unique-generator are also shared in a PAC.

DCT

Although the DCT resources themselves are stored in the PSOR, the actual queue must be one of the following DCT types in order for it to be stored in a SOR by a SOR Model:

• Non-recoverable
• Intra-partition - which includes triggers
• Indirect - model prefixes work only on the target DCT

Note: Recoverable, internal reader, and extra-partition types cannot be stored in a SOR.

When viewing information about TD queues in ESMAC, the following apply:

• Information regarding SOR stored queues, such as number of items and depth, can be viewed by any enterprise server instance.
• Information regarding queues stored on disk is only available to the local enterprise server instance.

FCT

The VSAM file referred to by the resource of this type can be stored in an RDBMS. See the MFDBFH configuration for requirements. Whether or not in MFDBFH, issuing a file close command in any enterprise server instance results in the file being closed by all instances in the PAC.

PCT

Active PCTs in a PAC will have two different count values:

• A count of the number of times the transaction has been executed across the PAC.
• A local count for each enterprise server instance of the number of executions in that instance.

PPT

Each enterprise server instance will load user applications from the location specified in its configured transaction path.

If you need to modify a program while a PAC is active, you need to uploaded the new binary file to the PSOR and then issue a New Copy command.

TST

Only non-recoverable queues can be stored in a SOR.

Temporary Storage and Transient Data Queues

Only non-recoverable queues are supported in Redis.

Temporary Storage (TS) and Transient Data (TD) queues can be directed to any SOR; they do not need to be directed to the same SOR that holds the TMP.

Indirect Queues

Model prefixes work on the target queue only:

Model prefix = MYQ

TDQ Name	Indirect Name	Storage location
MYQ1	TDQ1	Disk
TDQ1	MYQ1	SOR

Triggering

This is supported.

Extra-partition Queues

PAC usage unsupported.

Internal Reader

This is supported.

CICS applications can direct a JCL jobstream to these queues (which are a special type of extra-partition queue) for execution by the JCL engine.

Temporary Storage Queue (TSQ)

This is supported.

Browsing

TSQ browsing supported.

EXEC CICS START @ TERMID

Exec CICS START with a Termid specified is supported in a PAC.

VSAM Share Options

These are supported.

JCL Support

JCL is supported in a PAC, without restrictions.

IMS Support

IMS is not supported in a PAC.
