Issue

• "Out of memory" warning dialogue window pops up when trying to access objects in Vista.
• How to create a performance log to monitor Vista's memory usage

Environment

All Operating Systems

TAC Vista 5.1.X - server and workstation

Cause

Memory usages exceeds the allocated memory on the PC.

Resolution

1. Check the memory usage.
   1. The first step is to simply check the memory usage of all the processes that are running. Open task manager (right-click on the task bar and select from the context menu).
   2. Select the tab Processes and check that there are no processes using a large amount of memory. Especially interesting are TACOS.exe (Vista server) and TACVistaExplorer.exe (Vista Workstation).
2. If everything looks OK here monitor Vista's memory usage.
   1. Click on Start->Run and type in perfmon. Click on OK.
   2. Select System Monitor in the menu-tree to the left.
      
   3. Click on the + (plus) symbol in the graph pane to the right.
   4. Use the following settings:
       
   5. Click add and then do the same adding TACVistaExplorer.
   6. In the same way add Memory - Available bytes
   7. Monitor the memory usage and check to see if anything unusual happens - if TACOS's memory usage is near the available bytes or if TACOS's memory usage keeps growing etc.
      
3. If it's possible to establish that TACOS and TACVistaExplorer are using a large percentage of the PC's memory, upgrade to Vista 5.1.6. and/or increase the physical RAM of the PC (if possible).
   A lot of improvements have been made to TAC Vista that have optimized memory usage. A significant reduction in memory usage should occur after upgrade.
