Preparing Solaris systems for installation

Before you can install IBM BPM, you must prepare your Solaris operating system.

Before you begin

Because WebSphere Application Server is a prerequisite of IBM BPM, you must complete the required preparation steps in the Preparing Solaris systems for installation topic in the WebSphere Application Server information center.

About this task

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.

Procedure

Complete the following steps on your Solaris systems before installing IBM BPM:

1. 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.

   Before installing, run the following command:

   • ulimit -Hn 8800

   Alternatively, you can use the following steps to edit the resource limits file:

   1. Open /etc/system

   2. Add the following line to the end of the file:

      • set rlim_fd_max=8800

   3. Save and close the file.

   4. Log off from the operating system and log in again.

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

   • umask 022

3. Complete the steps in Tuning Solaris systems.
