Troubleshoot: The removeNode command returns an out of memory error

The removeNode command returns a node from a network deployment cell to a stand-alone application server.

 

Problem

When executing the removeNode command, an out of memory error is encountered.

 

Solution

If this error occurs:

1. AIX|Linux|Solaris|Ensure that the removeNode.sh command is not running.

2. Windows:

   Ensure that the removeNode.bat command is not running.

3. AIX|Linux|Solaris|Log on as root.

4. Open the following file in a text editor:

   • AIX|Linux|Solaris|WAS_installdir/bin/removeNode.sh

   • Windows:

     WAS_installdir/bin/removeNode.bat

5. In the text file, find the following line of text:

   • AIX|Linux|Solaris|"$JAVA_HOME"/bin/java \

   • Windows:

     "$JAVA_HOME"\bin\java \

6. Insert the following line of text below the "$JAVA_HOME"/bin/java \ line of text

   -Xmx
   max_allowedm \
   

   Where max_allowed is the maximum value allowable by your operating system. This value must a multiple of 1024. Append the letter k or K to indicate kilobytes, or m or M to indicate megabytes.

7. Save the changes and exit the text editor.

8. Windows:

9. Windows:

   Expand System Administration > Deployment Manager > Java and Process Management > Process Definition > Java Virtual Machine.

10. Windows:

    You can reduce this number once you have completed the removeNode process.

11. Windows:

    Restart the Deployment Manager.

    1. Restore the configuration backup you made when removing the node of by issuing one of the following commands:

       • AIX|Linux|Solaris|WAS_installdir/bin/restoreConfig.sh backup_file.zip

       • Windows:

         WAS_installdir/bin/restoreConfig.bat backup_file.zip

       where backup_file is the full path to the backup file.

    2. Run the removeNode command again.
