00C20204

Explanation
 Db2 is unable
to connect to a group buffer pool because MVS detected
a problem on the IXLCONN request.

System action
 SQLCODE -904 (resource not available) and the
group buffer pool name are returned to the user. Unless already issued
for the IXLCONN code, message DSNB301E, which contains this reason
code and the IXLCONN code, is issued to the console.

User response
 Contact the system programmer.

Problem determination
 The reason code returned by the IXLCONN
request is given in message DSNB301E.
 If the connection
problem was caused by insufficient storage in a coupling facility,
tell the MVS system administrator
to alleviate the storage constraint problem by making additional storage
available to the involved coupling facility, or by changing the active MVS CFRM administrative policy to redefine the coupling facility structure to a different coupling facility.  Another alternative is to have the database administrator reassign those inter-Db2 sharing page sets to a different Db2 buffer pool.
