DFS0764A PAGE FIX FOR EXCPVR-REQUIRED AREAS FAILED. REPLY 'RETRY' OR 'EXCP'.

Explanation
 The IMS system
attempted to PAGE FIX areas of storage for the EXCPVR option. The
operating system was unable to satisfy the request. The operator can retry
the PAGE FIX or answer EXCP, which cancels the EXCPVR option.

System action
 IMS waits
for the operator reply.

Operator response
(z/OS® System)  The
operator can reply EXCP to cancel the EXCPVR option or can attempt
to make fixable storage available and then answer RETRY. Fixable storage
can be made available by stopping other jobs within the operating
system. Decreasing general activity within the operating system can
also make fixable storage available.
