Prepare the Solaris operating system

View information on setting up your operating system for WebSphere Portal. Other components might require additional steps; see the product documentation for the specific components you want to install.

Prerequisites

Prepare prerequisite and corequisite software on Solaris

To prepare your operating system:

1. To prepare the Solaris kernel settings:

   Several Solaris kernel values are typically too small for the messaging requirements of WebSphere Portal. Starting the internal JMS server or client with insufficient kernel resources produces a First Failure Support Technology (FFST) file in the /var/errors directory.

   Before installing WebSphere Portal, review the machine's configuration.

   The values described here are a starting point for messaging in WebSphere Portal only.

   If your system has other applications installed, the value requirements will likely be different.

   For example, if values that are already set are higher than the settings listed here, the values should NOT be lowered. Be sure to check the requirements made on /etc/system by other already-installed applications before altering existing values.

   1. Type the sysdef -i command to review the configuration.

   2. Set shmsys:shminfo_shmmax (valid for Solaris Version 9 only) to 4294967295.

   3. Set shmsys:shminfo_shmmni (valid for Solaris Version 9 only) to 1024.

   4. Set semsys:seminfo_semaem (valid for Solaris Version 9 only) to 16384.

   5. Set semsys:seminfo_semmni (valid for Solaris Version 9 only) to 1024.

   6. Set semsys:seminfo_semmns (valid for Solaris Version 9 only) to 16384.

   7. Set semsys:seminfo_semmsl (valid for Solaris Version 9 only) to 100.

   8. Set semsys:seminfo_semopm (valid for Solaris Version 9 only) to 100.

   9. Set semsys:seminfo_semmnu (valid for Solaris Version 9 only) to 2048.

   10. Set semsys:seminfo_semume (valid for Solaris Version 9 only) to 256.

   11. Set msgsys:msginfo_msgmap (valid for Solaris Version 9 only) to 1026.

   12. Set msgsys:msginfo_msgmax (valid for Solaris Version 9 only) to 65535.

   13. Set rlim_fd_cur to 1024.

   14. Reboot the operating system to apply the updates.

2. Web Content Management only:

   Use the ulimit -f command to set the maximum size of files that can be created to be at least the size of the largest file you would need to upload to the content server. The command ulimit -f -1 removes any limit on file size.

3. To prepare for non-global zone:

   1. Do not inherit package directories when you create the non-global zone because the inherited software packages will be read-only.

   2. Stop WebSphere Portal and all related processes before installing or uninstalling.

   3. Verify that the following processes are stopped:

      • /opt/IBM/WebSphere/AppServer/java/bin/java

      • /opt/IBM/WebSphere/AppServer/java/jre/bin/java
