Warnings about GTK or ulimit on Linux or UNIX when installing or migrating

On the Linux or UNIX operating system, when you are installing or migrating, you might see a warning about 32-bit GTK libraries or increasing your ulimit.

GTK warning

If you are on a 64-bit system, you might receive the following message:

Your operating system failed the launchpad prerequisites check. The following 32-bit GTK Library for running IBM Installation Manager is not available in underlying OS:  list_of_missing_files. Please install the 32-bit GTK Library and restart your installation.

If you see this message, your server does not have the 32-bit version of the GTK library installed, or the library is an incorrect version. You must update your server with the correct version of the 32-bit GTK library before you continue the installation.

You can get the library from the DVD or official website of your operating system.

ulimit warning

If you receive the following warning message during the prerequisite checking, use the platform-specific steps below to increase the ulimit number.

Current system has detected a lower level of ulimit than the recommended value of  recommended_value. Please increase the ulimit number to minimum value of  recommended_value and re-start the installation.

Shutdown your installer. If you are a root user open a command prompt and issue ulimit -n  recommended_value and then restart the installer. If you are a non-root user, work with your system administrator to increase your ulimit -n  recommended_value and then restart the installer.

The required value is calculated based on the version of WebSphere Application Server and the configuration that you are installing.

1. Set the maximum number of open files using the following steps:
   
   1. Open /etc/security/limits.
   2. Edit or add the default section and include this line:

      nofiles = recommended_value

   3. Save and close the file.

   4. Log off and log in again.
   
   
   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 recommended_value

      * soft nofile recommended_value

   3. Save and close the file.

   4. Log off and log in again.
   
   
   1. Open /etc/system and add the following line to the end of the file:

      set rlim_fd_max=8800

   2. Save and close the file.

   3. Log off and log in again.
2. Restart the computer.
3. Restart the installer.
