Operating system

Oracle WebLogic is certified on various operating systems, such as:

  • Linux versions, including as Redhat, Oracle Linux, and SLES
  • Sun Solaris
  • HP-UX
  • AIX
  • Windows 2000-2003-2008 Server, XP

For a complete list of certified operating systems, see the Certification Matrix at http://www.oracle.com/technetwork/middleware/downloads/fmw-11gr1certmatrix.xls.

In your case, you will choose Oracle Enterprise Linux version 5, which is somewhat similar to the Redhat version. You can download it from Oracle TechNet.

The rest of this chapter will focus on installing WebLogic on a Linux platform.

Other prerequisites

  • There should be a dedicated operating system user as the local owner of the WebLogic Server software. The typical name would be oracle, assigned with the group oinstall.
  • There should be some file prerequisites set for the user:

    File limits should be set in /etc/security/limits.conf 

    # /etc/security/limits.conf
#<domain> <type> <item> <value>
weblogic hard nofile 4096
weblogic soft nofile 4096
  • On some Linux systems, the /tmp filesystem is of a very small size. If this is the case, ask your OS administrator to increase it or else choose your own directory. This can be accomplished by entering the following option on the command line, when you start the installation program:
    -Djava.io.tmpdir=tmpdirpath
  • Here, tmpdirpath is the full path of the directory that you want to designate as a temporary storage area for the installation program.
