Monitoring, Version 6.2
On AIX®, the Tivoli Enterprise™ Portal Server process (KfwServices) is linked with the default memory model, which allows for data and stack storage of only 256 MB. In large environments, this can cause the portal server to crash at startup. In smaller environments, this may not cause a problem at startup, but may cause a problem at some later point as more virtual storage is required.
The problem can be predicted if the AIX topas command shows KfwServices with PgSp value of 180-250 MB. If a smaller environment is close to that value, it may occur when large queries are being handled. If the topas output shows that KfwServices is nearing these values, the memory model should be changed in smaller environments as well as large ones. See “Increasing virtual memory on AIX for large environments" in the IBM Tivoli Monitoring Installation and Setup Guide for instructions for changing the memory model.
