Create an integrated Windows server memory dump on i5/OS

You can create a Windows memory dump file on i5/OS to help you solve integrated server problems. When you install Windows server on iSeries, by default the dump goes to the system drive.

• %SystemRoot%\Memory.Dmp for Windows Server 2003.
• %SystemRoot%\Memory.Dmp for Windows 2000 servers.

Note:

For Windows to successfully create a complete memory dump the pagefile must reside on the system drive and be at least equal to the memory size plus 12 megabytes. The memory contents are written into the pagefile during the dump. This is the first step in the memory dump process. During the second step the data from the pagefile is written to the actual dump file. This step occurs when the system is booted again after the dump. The drive that contains the memory dump file (memory.dmp by default) must have free space at least as large as the amount of installed memory.

The memory dump is enabled by default if the system drive has enough room for the paging file. To verify that the memory dump support is enabled or to write the memory.dmp file to a different drive, follow these steps.

1. Go to Start, then Settings, then Control Panel.
2. Open the System application.
   • Click the Advanced tab, then the Startup and Recovery button.
3. Click on the Write Debugging Information To check box.
4. Change the location of the dump file if necessary.
5. If you want the system to overwrite the file every time a Kernel STOP Error occurs, click the Overwrite any Existing File check box.
6. Select the appropriate type of memory dump (Small Memory Dump, Kernel Memory Dump, or Complete Memory Dump) based on the size of the page file and the amount of free space available on the system drive.
7. Click OK.
