Set the Limit on the Number of Open Files on CA Performance Center

Verify that the user account that is installing CA Performance Center has a value of at least 65536 on the number of open files. Set this value permanently.

Follow these steps:

1. As the root user or a sudo user, log in to the computer where you are going to install CA Performance Center. Open a command prompt and type the following command to change the ulimit for the open files limit to at least 65536:

   ulimit -n ulimit_number
   

   For example:

   ulimit -n 65536
   

2. Open the /etc/security/limits.conf file on the computer where you are going to install CA Performance Center and add the following lines:

   # Added by Performance Center
   * soft nofile 65536
   # Added by Performance Center
   * hard nofile 65536
   

   Note: Restart CA Performance Center for these changes to take affect. If you are upgrading, the upgrade process automatically restarts CA Performance Center.

3. To verify that the number of open files is set properly on the computer where you are going to install CA Performance Center, type the following command:

   ulimit -n
   

   The command returns the ulimit number that you specified earlier.
