| ES_DFS3650

The default transaction to execute or MOD file to be displayed after successfully signing on to IMS. You specify these by setting environment variables prior to the start of the region: ES_DFS3650 - set to MOD if a MOD file is to be sent, or TRX if a TRANSACTION is to be executed. If you set to MOD, ES_MOD3650 needs to be set to the name of the MOD you want to display. If you set to TRX, ES_TRX3650 needs to be set to the name of the transaction.
|
| ES_IMS_CONFIG

|
Deprecated. See
IMS Database Locking. When set to 1, directs batch program execution to process all IMS DB calls entirely in the JES initiator providing significant performance improvement. All IMS DB control processes accessed from the batch program must be stopped before execution because they become exclusively owned by JES until the program completes.
|
| ES_IMS_LOCK_TIMEOUT
|
The number of seconds during which IMS DB control continues to retry a locked record before timing out. Valid values are 0 to 65535. The default is 30 seconds; a value of 0 indicates an indefinite wait time.

|
| ES_IMS_PLI_INDIRECT_PCBADDR
|
Determines whether the PL/I program converts the PCB address list from a direct to an indirect addressing technique. Set the variable to one of the following values:
- D
- If the main program is a PL/I program, PCB addresses are converted from a direct to an indirect addressing technique.
- Y
- Always converts addresses from a direct to an indirect addressing technique as long as the PSB language is set to PL/I.
- N
- Never converts addresses from a direct to an indirect addressing technique.
The default is D (dynamic).
|
| ES_IMS_RCLASS
|
Creates a set of newly-named IMS security resource classes, appending the variable's value (maximum of seven characters) to each resource class' default character.
Create theses custom-named classes if you are using the same ESM active directory with two Enterprise Server systems and your security needs to differ for each.
See
Resource Classes for IMS Security for the names of the resource classes created if this variable is not set.
|
| ES_IMS_RELEASE
|
