Abstract
In an IMS/ESA environment, an ITASK is provided so as periodically to check IMS application programs to determine whether any is hung, thus providing notification for hung transactions that sometimes occur after an asynchronous APPC call issued by IMS from the IMS dependent region during syncpoint processing. APPC calls cause a time stamp to be written, which is used by the ITASK to determine how long the transaction is in a response wait state. The ITASK is reactivated after a waiting period dynamically determined on the basis of the processes active and a minimum interval. Detection of hung transactions results in a remedial action being taken.
