GROUP NAME field (GRPNAME subsystem parameter)
The GRPNAME subsystem parameter identifies the name of a new or existing Db2 data sharing group that is to be used for this subsystem.
| Acceptable values: | 1–8 characters consisting of letters A–Z, numbers 0–9, $, #, @ |
|---|---|
| Default: | DSNCAT |
| DSNZPxxx: | DSN6GRP GRPNAME |
The group name encompasses the entire data sharing group and forms the basis for the coupling facility structure names.
To avoid names that IBM® uses for its z/OS® cross-system coupling facility (XCF) groups, the first character must be an uppercase letter J - Z unless the name begins with DSN. Do not use SYS as the first three characters, and do not use UNDESIG as the group name.
