DSNT547I THE RESULT OF THE WLM REFRESH REQUEST IS UNKNOWN BECAUSE THE SYSTEM DID NOT REPLY WITHIN n SECONDS
Explanation
The DB2®-supplied stored procedure, WLM_REFRESH, accepted and validated the request to refresh a WLM environment and passed it to z/OS® for processing. However, z/OS did not respond within the wait period of n seconds.
System action
WLM_REFRESH terminates with return code 4.
System programmer response
This message indicates that your system is suppressing one or more of the messages that can be generated in response to the VARY WLM command. DSNTWR, the external module for WLM_REFRESH, uses an extended MCS console (also named DSNTWR) to monitor whether or not the VARY WLM command succeeded or failed. Messages with the IDs IWM032I (refresh complete) and IWM031I (refresh in progress) indicate that the refresh request processed successfully. So, for WLM_REFRESH to function correctly, you need to ensure that the system does not suppress messages IWM031I and IWM032I.
This error can also occur if the specified WLM environment requires more than n seconds to refresh. In this case, you need to increase the wait time allowed for the reply by updating the setting of the WAITLMT constant in the source code of the external module for WLM_REFRESH, DSNTWR. You need to prepare and bind DSNTWR again for the change to take effect.
