DSNB301E csect-name GROUP BUFFER POOL gbp-name CANNOT BE CONNECTED DB2 REASON CODE = reason-code MVS IXLCONN REASON CODE = ixlconn-reason

Explanation

Db2 was not able to connect to the named group buffer pool. This message is generally issued once for each Db2 subsystem for each Db2 reason code, except 00C20204, until the failure condition is corrected.
csect-name
The name of the control section that issued the message.
gbp-name
The name of the group buffer pool.
reason-code
The Db2 reason code.

For Db2 reason code 00C20204, which indicates a problem during MVS IXLCONN processing, the DSNB301E message is issued once for each Db2 subsystem for each IXLCONN reason code until the failure condition is corrected.

ixlconn-reason
When the Db2 reason code is 00C20204, the MVS IXLCONN reason code. For all other Db2 reason code values, ixlconn-reason contains zeros.

System action

If the connection was requested on behalf of an access request by an SQL user on this Db2, SQLCODE -904 (resource unavailable) is returned to the SQL user with the Db2 reason code shown in this message.

If the connection was requested on behalf of an SQL user on another Db2 in the data sharing group, SQLCODE -904 (resource unavailable) is returned to the SQL user with Db2 reason code 00C20252. This indicates that the requested table space or index space is unavailable because another Db2 cannot connect to the group buffer pool.

If the MVS IXLCONN reason code is xxxx0C08 (structure allocation failed because there was no suitable facility to allocate based on the preference list in the MVS CFRM administrative policy), or if the MVS IXLCONN reason code is xxxx084C (user does not have proper Security Access Facility (SAF) authorization), then IFCID 0250, if active, contains additional diagnostic information.

System programmer response
