DLI parameters

The following figure is displayed when you select Option 2, DLI Parameters, from the Parameters Selection Menu. Use this screen to view/modify the current DLI parameter information.

Important

Fields blanked out on the screen default to their associated values in the current IMS environment definition. All changes to the fields remain in effect and are saved from session to session.

If you allocate the DFSRESLB, DFSVSAMP, or RECON DDs before invoking File-AID for IMS/ISPF, it does not attempt to allocate or de-allocate them. File-AID for IMS/ISPF also does not validate the data sets that you allocated to DDs.

Changes here override the current environment defaults. When selecting another environment using Option E, you have the option to retain the current setting or restore environment defaults (see Retain environment modifications).

Use the RESTORE command to remove override values and use environment defaults.

Important

Some fields are cleared (blank) while others actually display the default settings for the current environment.

DLI PARMS

Specify the DL/I parameters to pass to DFSRRC00 (the IMS region controller). File-AID for IMS generates the "DLI, pgmname, psbname," portion of the DFSRRC00 parameters and concatenates them in front of the DL/I parameters. The DL/I parameters syntax contains 15 commas:

,0000,,,,,,,,,d,i,,b,,

where:

- d represents DBRC and can be C, Y, N, or NULL.
- i represents IRLM and can be Y, N or NULL.
- b represents BKO and can be Y, N, or NULL.

We recommend that you specify Y in the BKO (backout) operand. The value Y enables you to update all secondary index source segments. The value N prevents you from updating secondary index source segments for which File-AID for IMS/ISPF cannot guarantee uniqueness. For more information, see IMS System Programming Reference.

BUF

Specify the number of 1K blocks, for calculating OSAM subpools if IOBF is not specified in DFSVSAMP.

SPIE

Specify whether to allow SPIE established by the application program. Valid entries are 0=Allow SPIE or 1=Negate SPIE.

TEST

Specify whether to validate addresses in call list. Valid entries are 0=Do not validate or 1= Validate.

EXCPVR

Specify whether to page fix OSAM buffer pool. Valid entries are 0=Do not page fix or 1=Page fix.

RST

Specify whether to allow UCF restart. Valid entries are 0=No or 1=Yes.

PRLD

Specify the preload list suffix, DFSMPLxx.

SRCH

Specify the module search indicator. Valid entries are 0 = Standard or 1=Search JPA and LPA first.

CKPTID

Checkpoint for restart of program.

MON

IMS monitor active. Valid entries are N=No or Y=Yes.

LOGA

This field is no longer used. The logging access method (0 = BSAM; 1 = OSAM).

FMTO

Specify the dump formatting option.

IMSID

Specify the IMS Subsystem ID.

SWAP

Specify whether to use swappable address space. Valid entries are Y=Yes or N=No.

DBRC

Specify the DBRC usage. Valid entries are:

- Blank=Use your system default.
- Y=Yes, always use DBRC.
- N=No, unless system forces it with DBRC=FORCE.

IRLM

Specify the IRLM usage. Valid entries are:

- Blank=Use your system default.
- Y=Yes, use IRLM.
- N=No, don't use IRLM.
