How Is a Memory Dump Taken

How Is a Memory Dump Taken? Technote (FAQ) Problem It has been determined that a memory dump must be taken on a Domino server to further narrow down a problem. How is this done? The following errors are some that would require the collection of a memory dump: "Maximum Number of Memory Segments that Notes Can Support Has Been Exceeded. " "Insufficient Memory. " "Insufficient Memory. NSF Pool is Full. " Solution Note: When you create a memory dump on your Domino server, the file is always saved with the same file name (memory. dmp). As a result, if the preceding memory. dmp file is not removed (or renamed) prior to initiating a subsequent memory dump, the information in the file will be overwritten. For information about avoiding that, refer to the document titled "How To Avoid Memory Dumps Being Overwritten on a Domino Server" (#193090). Method 1: To create a Notes memory dump, do the following: 1. From an operating system prompt, switch to the Notes program directory. 2. Issue one of the following commands, depending on whether the server is R4 or R5: R4 Servers: notes server -m R5 Servers: nserver -m NOTE: For Unix machines (Solaris, AIX, HP-UX), the command is: server -m This will create a file called MEMORY. DMP that will be placed in the Notes\Data directory. NOTE: If the memory dump is being collected on a Domino partitioned server, the following command should be issued after switching to the Notes program directory and before the memory dump is actually taken (this will set the partition on which the memory dump will be taken): Set Notespartition="x" (where "x" represents the number of the partition on which you want to run the memory dump. ) The MEMORY. DMP file should be sent in to Lotus Notes Support for analysis. Method 2: Another way to take a memory dump is with the following command on the server console: sh memory dump This will yield the memory available, including virtual memory on the server console. It will also create a MEMORY. DMP file in the Page 1 of 2IBM - How Is a Memory Dump Taken? 15/08/2008http://www-1. ibm. com/support/docview. wss?rs=899&context=SSKTK9&con. . .
