Specifying subsystem options

The subsystem options are in the OPTIONS member of the control data set that the GLOJCNTL member JCL generates.

About this task

Note:
  • Subsystem options settings take effect when the started task that is associated with the specific subsystem options member is started.
  • You cannot specify the subsystem options member name as parameter on a command.

Procedure

To specify subsystem options, modify the following settings.
DSN_PATTERN_MATCHING
Specify data set name pattern-matching for the selection criteria DSNAME, DSNAME_DATA, DSNAME_INDEX, and LOGSTREAMID. Specify one of the following options:
BASIC
(Default.) Specify default data set name pattern-matching.
  • One percent sign matches one (required) character.
  • One asterisk within a qualifier that contains other characters and wildcard characters, matches 0 - 8 characters within the qualifier.

    If you specify a single asterisk to denote a qualifier, for example .*. or .*, it matches on one or more qualifiers. If no such qualifier exists, the match fails because BASIC pattern matching searches for a string and is not aware of individual qualifiers.

Important: For existing users who installed Advanced Allocation Management, changing from the default of BASIC requires that you carefully review the data set name patterns that are specified for DSNAME, DSNAME_DATA, DSNAME_INDEX, and DSNAME_LOGSTREAMID selection criteria to ensure that your current rule definitions continue to work as expected.
EXTENDED1

Specify extended data set name pattern matching.

  • A single percent sign matches on a single (required) character.
  • A single asterisk, within a qualifier that contains other characters, matches on 0 - 8 characters. A qualifier that consists of a single asterisk represents one (required) qualifier.
  • Double asterisks match zero or more qualifiers. A trailing qualifier of double asterisks (.**) matches zero or more qualifiers.
EXTENDED2
The EXTENDED2 option works in the same way as the EXTENDED1 option. In addition, a trailing qualifier of a single asterisk (.*) matches zero or more qualifiers.

In all cases, specifying double asterisks within a qualifier, such as ABC.D**EF, is not permitted.

INITIAL_RULEDEF
Specify the name of the rule definitions member to use upon startup. For example: RULESABC, RULESET2, and so on. The default is RULEDEFS.
INITIAL_VGRPDEF
Specify the name of the volume group definitions member to use upon startup. For example: VGRPFST, VGRPD002. The default is VGRPDEFS.
S1_INTERCEPT
Specify whether to enable or disable the initialization of the S1 (STOW) intercept at product startup. Specify one of the following options:
ENABLE
(Default.) Enable the initialization the S1 (STOW) intercept at product startup. To use the PDS_DIR_INC function, you must set S1_INTERCEPT to ENABLE.
DISABLE
Disable the initialization of the S1 (STOW) intercept at product startup. Specify DISABLE only when conflicts occur with other software that intercepts STOW processing.
Note: If you modify the S1_INTERCEPT setting in the OPTIONS member, you must IPL the system and restart Advanced Allocation Management so that the new setting takes effect.
SECURITY_CLASS
The default is FACILITY.
SMF_RECORD_ID
Specify the SMF record type to use for Advanced Allocation Management.
Notes:
  1. If you do not specify the SMF record type, Advanced Allocation Management will not write SMF records.
  2. If you are already recording SMF data for a product and want to record SMF data for Advanced Allocation Management, you must select a new, previously unused record type.

For information about how Advanced Allocation Management uses the SMF record type that you specify, see Event recording and reporting.

SSID
You must specify a unique 4 character alphanumeric subsystem ID for each specific instance of Advanced Allocation Management. For example, specify AOP1, AOP2, and so on. The default subsystem ID is AOPT.
VARDEFS_MEMBER
Specify the name of the variables definitions member to use upon startup. The default variables definitions member name is VARDEFS.
Note: To later change the variables definitions member, use the following command:

F glostc,SETVARDEFS membername

Where membername is the name of the variables definitions member to use.

RLS_INTERCEPT
Specify whether to enable or disable the initialization of the RLS (record-level sharing access mode) intercepts at product startup. Specify one of the following options:
ENABLE
(Default.) Enable the initialization of the RLS (record-level sharing access mode) intercepts at product startup. To use any of the secondary allocation functions for the VSAM data sets that are accessed in RLS access mode, you must set RLS_INTERCEPT to ENABLE.
DISABLE
Disable the initialization of the RLS (record-level sharing access mode) intercepts at product startup.
Note: If you modify the RLS_INTERCEPT setting in the OPTIONS member, you must IPL the system and restart Advanced Allocation Management so that the new setting takes effect.
Z1_INTERCEPT
Specify whether to enable or disable initialization of the Z1 (step termination) intercept at product startup. Specify one of the following options:
ENABLE
Initialize the Z1 intercept at product startup. Specify ENABLE only if you want to use the DATASET_INIT function.
DISABLE
(Default.) Do not initialize the Z1 intercept at product startup.
Note: If you modify the Z1_INTERCEPT setting within the OPTIONS member, you must IPL the system and restart Advanced Allocation Management so that the setting takes effect.
