Explanation
Db2 cannot connect to a group buffer pool. The group buffer pool is not usable by this release of Db2. This Db2 subsystem is a member of a data sharing group containing Db2 members of different release levels. A later release level of Db2 specified an option for this group buffer pool that is not supported by the previous Db2 releases. The presence of this option makes the group buffer pool inaccessible to the previous Db2 releases.
System action
Db2 takes
the following actions:
- Unless already issued, message DSNB301E is sent to the console with this reason code to indicate that a connect failure occurred.
- SQLCODE -904 (resource not available) is returned to the user with this reason code. The resource type and resource name are also returned. For an explanation of resource-type and resource-name values, see Resource types.
System programmer response
Take one of the following actions:
- Issue the -ALTER GROUPBUFFERPOOL command from a Db2 that is at the later release level to remove the new option so that previous release levels of Db2 can access the group buffer pool.
- Migrate the previous release levels to the current release.
