Increase the user process limits for the apg user account to a maximum of 65536. This modification enables services to open 65536 files and 65536 processes when needed. This step is required for proper functioning of the core software.

Prerequisites

  • Make sure you have a login with root privileges.
  • The core software installed on a server running Red Hat Enterprise Linux 6/7, CentOS Linux 6/7, or any other supported Linux operating systems.

Procedure

  1. Open the /etc/security/limits.conf file.
  2. Add the following lines for the user.
    In this example, the user is apg. 
    apg   hard  nofile  65536
apg   soft  nofile  65536
apg   hard  nproc   65536
apg   soft  nproc   65536
  3. Save the file.
  4. To verify the changes, type the following command:
    su apg -c 'ulimit -n -u'
    Following is the output: 
    open files                      (-n) 65536
max user processes              (-u) 65536
  5. In the opt/APG/bin/apg.properties file, edit the hostname to a FQDN host name.
  6. To restart the services, type the following commands from the bin directory of the installation:
    ./manage-modules.sh service stop all
    ./manage-modules.sh service start all
