DSNB892I grpname IS NOT A VALID GROUP NAME FOR THIS DB2

Explanation

The group name specified as part of the full coupling facility cache structure name on an ALTER GROUPBUFFERPOOL or DISPLAY GROUPBUFFERPOOL command is incorrect. On the commands, you can specify either the correct 16-byte coupling facility cache structure name or the Db2 group buffer pool name. The coupling facility cache structure name is a 16-character name specified as follows: 
 groupname_gbpname

The gbpname can be GBP0, GBP1, ..., GBP49 GBP32K, GBP32K1, ..., GBP32K9. The groupname is the Db2 data sharing group name. The underscore (_) is used as a delimiter between the groupname and the gbpname. The coupling facility cache structure names are left-justified with a blank as the rightmost padding character. Db2 adds the padding blanks if they are not specified on the command.

System action

The request is rejected.

System programmer response

Reissue the command, specifying a valid group buffer pool name.
