COMM (Communicate with MUF) › COMM REQABORT (Abort a Request) › When to Use

When to Use

Use this option to terminate a request that has been waiting or running a long time due to one of the following:

Primary or secondary exclusive control
Many read I/O events
Waiting on a task

Requests which can impact wait time and for which this command is effective are LOCxx, REDxx, RDUxx, GETxx, CNTxx, and SELxx requests.

Also supported are ADDIT, DELET, and UPDAT commands. If one of these commands is subjected to REQABORT, the request, though aborted, is subject to a rollback to reverse any data area or Index Area changes made.

If commands are executing on behalf of an SQL request, the REQABORT might be accepted immediately or delayed. The decision to accept immediately or delay the REQABORT request is based upon the SQL process that is executing.
