DFS4380W OTMA XCF MESSAGES FROM member
name HAVE REACHED 80% OF THE MAXIMUM MESSAGE LIMIT nnn
Explanation
OTMA processing could slow down because a problem
with RACF® I/O, queue manager
I/O, or other unknown internal component was encountered by the IMS system. XCF messages from an
OTMA client, such as IMS Connect or IBM® MQ,
can pile up in the IMS causing
a potential flood condition. When OTMA detects this condition, OTMA
issues this warning message. It then sends out a protocol message
to the OTMA client so that the client can reroute the subsequent transactions
to a different IMS. The XCF messages
from the OTMA client eventually are processed by the IMS when the slow down condition is relieved
or resolved. If the OTMA transaction expiration function is activated
in the IMS system, these XCF
messages could be discarded.
System action
Processing continues. An OTMA protocol message with
the warning status is sent to the OTMA client.
System programmer response
A potential XCF message flood has occurred
in this IMS. Reroute new transaction
requests to a different IMS.
