IIS Configuration

By default in IIS, the default application pool recycles worker processes every 1740 minutes (29 hours). This means that on HPOM for Windows management servers, IIS restarts the HPOM Incident Web Service every 29 hours. This restart may cause problems with any operations that are in progress. In particular, restarting the service releases any enumeration contexts. After it releases an enumeration context for a subscription, the service does not maintain an event queue of new or updated incidents until the client subscribes again. (See SubscribeOp.)

You can avoid this problem by disabling worker process recycling. In addition, you should develop clients that can handle a restart of the service.

To disable worker process recycling:

1. In Internet Information Services (IIS) Manager, right-click DefaultAppPool, and then click Properties. The DefaultAppPool Properties dialog box opens.

2. Clear the Recycle worker processes check box.

3. Click OK.
