Managing the event processor
About this task
The only maintenance issue for the event processor is the management of the EIF event queue, cache.dat. The event queue is circular, with events being added at the end and removed from the beginning. However, if there is no room to write an event at the end of the queue it is written at the beginning, overwriting the event at the beginning of the queue.
To increase the size
of the event processor queue, follow this procedure:
- At the workstation running the event processor, locate the file:
where WAS_profile_path corresponds to the WebSphere Application Server profile path you specified at installation time. The default path is TWA_home/WAS/TWSprofile.<WAS_profile_path>/temp/TWS/EIFListener/eif.templ - Edit the file and locate the keyword:
BufEvtMaxSize - Increase the value of this keyword, according to your requirements.
- Stop and restart the WebSphere Application Server using the conman stopappserver and conman startappserver commands (see Starting and stopping the application server and appservman).
