SUBGRP ATTACH field
The SUBGRP ATTACH field identifies the name of a new or existing subgroup attachment that is to be associated with this subsystem. A subgroup attachment name can be specified with a group attachment name to organize how TSO, CAF, RRSAF, JDBC, ODBC, and Db2 utilities connections find an active Db2 subsystem.
Acceptable values: | blank, 1–4 characters. Characters must be letters A–Z, numbers 0–9, $, #, or @ |
---|---|
Default: | blank |
Update: | modify IEFSSNxx and IPL |
DSNZPxxx: | none |
The value that you specify for the SUBGRP ATTACH field is used in the IEFSSNxx member of SYS1.PARMLIB.
The default value, blank, means that the member that is specified in the MEMBER NAME field is not to be associated with a subgroup attachment. If a subgroup attachment name is entered in the SUBGRP ATTACH field, a group attachment name must also be specified in the GROUP ATTACH field. A subgroup attachment can belong to only one group attachment and cannot have the same name as the group attachment. A member can belong to one subgroup attachment at most.
