Some system admins have very little paging space configured to ensure everything stays in memory. The collection (a new binary occurrence) starts every 24 hours, ensure that the file system you are looking for has not been added and mounted too recently to be captured by nmon. In the above output, we can determine that user ukinst2 is using 1.16 GB of  real memory, 30MB is used by the paging space, 30MB is pinned in memory, and 50MB is currently in virtual memory. (ie hostname_YYYYMMDD.nmon). This approach is generally used when performance is a high priority and no paging of the application should happen. Using this information, anyone should be able to find what the potential performance issues might be and, more importantly, where the source of the problem is. See nmon -h for the details. The application to be pinned will require further configuration for this, so use the following vmo command to view current attributes set: In normal operations, AIX will move page frames that contain files and programs around in order to free up memory.
