Prepare the AIX operating system

  1. If we have AIX 7.1 Technology Level (TL) 1, Service Pack (SP) 0 or 1, find the corresponding technote available at the HCL WebSphere Portal Knowledge Base Technical Articles and complete the steps.

  2. Set the file descriptor limit to 10240.

      ulimit -n 10240

  3. Set max size of files.

    For Web Content Manager only:

    1. Determine the size of the largest file we must upload to the content server.

    2. Use ulimit -f to set the maximum size to be larger than the result.

        ulimit -n maxfilesize

      To remove any limit on file size, run:

        ulimit -f unlimited

  4. If we are using IBM General Parallel File System (GPFS), set the file system inodes limit to 25000 or higher. For example, run...

      mmchfs /dev/gpfs1nsd -F 250000

    /dev/gpfs1nsd is the HCL WebSphere Portal installation file system.

  5. To use the graphical user interface the installation program provides, configure X server on AIX (such as X Window System or GNOME)

  6. Increase the paging space 1024 - 8192 MB.

  7. To install in a Work Load Partition (WPAR)

    1. Review guidelines in this technote.

    2. Request new IP address and host name on the same subnet as the host system.

    3. Create a WPAR containing a non-shared file system. A non-shared file system means /usr and /opt are private to this new WPAR.

        mkwpar -r -l -n newhostname

    4. Verify that the mkwpar task completed successfully.

    5. Use the host system smitty to configure network interfaces with the new information.

    6. Use the telnet or ssh command to connect and log in to the system.

    7. Verify that the /usr and /opt directories are writable.

  8. Ensure that the DB2 settings are not defined within the root user environment where the installation program runs. DB2 cannot be included within the PATH, the DB2INSTANCE variable cannot be set, and the root user is not required to run the db2profile command. The HCL WebSphere Portal and WCM packages installs a copy of DB2 for its own use and definitions within the root environment for other DB2 installations can interfere with that process.
