Preparing Linux systems for installation

Before you can install IBM Integration Designer, you must prepare your Linux operating system.

Because WebSphere Application Server is a prerequisite of IBM Integration Designer, complete all the required preparation steps in the Preparing Linux systems for installation topic in the WebSphere Application Server information center.

Ensure that you have Mozilla Firefox installed at version 3.5.x.x or higher.

Because certain steps are specific to a version of the operating system, all steps might not apply to your environment. If no qualifier is provided for a particular step, complete the step for all versions of the operating system. To install Installation Manager on Red Hat Enterprise Linux 6.0 (64-bit), see Unable to install Installation Manager on RHEL 6.0 (64-bit).

Cognos bundles an alternate version of the libfreebl3.so library for Red Hat Enterprise Linux 6.0 (64-bit). Ensure that you preinstall this system library that is required for other utilities.


Procedure

Complete the following steps on your Linux system before installing IBM Integration Designer:

  1. If you are planning to install IBM Integration Designer using DB2 Express with Red Hat Enterprise Linux 6, ensure that the user has administrative privileges (root user). As a root user, you must also ensure that all kernel requirements are met before the DB2 Express installation begins. You can locate the current values by parsing the output of the ipcs -l command. To change the values:

    1. Add the following lines, in the following order, to the /etc/sysctl.conf file: 
      kernel.shmmni=4096 
kernel.shmmax=4294967296 
kernel.shmall=8388608 
#kernel.sem=<SEMMS><SEMMNS><SEMOPM><SEMMNI> 
kernel.sem=250 256000 32 4096 
kernel.msgmni=16384 
kernel.msgmax=65536 
kernel.msgmnb=65536

    2. Add the following lines to the end of the /etc/security/limits.conf file: 
      # - stack - max stack size (KB)
* soft stack 32768
* hard stack 32768
# - nofile - max number of open files * soft nofile 65536
* hard nofile 65536
# - nproc - max number of processes * soft nproc 16384
* hard nproc 16384
    3. Reboot your system.

  2. If you are NOT planning to install IBM Integration Designer using DB2 Express, increase the maximum number of open files. The default setting is usually not enough. You can check your current maximum number of open files by using ulimit -n. The following example shows the maximum number of open files being increased to 8800, which is large enough for most systems. The ulimit requirement is dynamically calculated at installation time and might need to be larger based on the options you select.
    1. Open /etc/security/limits.conf.
    2. Locate the nofile parameter and increase the value. If a line containing the nofile parameter does not exist, add the following lines to the file:

      * hard nofile 8800

      * soft nofile 8800

    3. Save and close the file.

    4. Log off and log in again.
    For more information about this setting, run man limits.conf or see the Preparing Linux systems for installation topic in the WebSphere Application Server information center.

  3. Install the following packages for your operating system:
    Option Description
    Red Hat Enterprise Linux 5

    • libXp-1.0.0-8
    • rpm-build-4.4.2-37.el5

    Red Hat Enterprise Linux 6 ksh-version.rpm Korn shell
    You can also install a later release of any of these packages if there are new packages as errata. If you have additional packages that are specific to your hardware, install them.

    The following command example shows how to use the default package manager on supported Linux distributions.

    • Red Hat Enterprise Linux 5: 
      yum install libXp rpm-build

  4. Set the umask value to 022 using the following command:

    • umask 022

  5. On Red Hat Enterprise Linux 5 systems, disable SELinux, or set it to a permissive mode.
  6. Restart the computer.

  7. Complete the steps in Tuning Linux systems.
