Planning and implementing for Linux

Linux High Availability provides an environment that ensures a fast and reliable recovery of important applications from hardware and software failures. Linux High Availability is referred to as Linux HA hereafter.

Before installing InfoPrint Manager or any of the components for your Linux HA configuration, you need to plan for the configuration of system resources, plan for the configuration of important file systems across your installation, and plan the sequence that products should be installed on your Linux server.

InfoPrint Manager supports Red Hat Enterprise Linux High Availability Add On and SUSE Linux Enterprise High Availability Extension.

The following sections provide the Linux HA implementation requirements for InfoPrint Manager:

  1. Resource configuration planning
  2. File system configuration planning
  3. Installation order planning
    Note:
  • If you are installing InfoPrint Manager for AIX in an existing high availability installation, you should note that InfoPrint Manager appends information to the end of the /etc/inittab file. If a high availability application has been installed on the AIX server before InfoPrint Manager for AIX, the InfoPrint Manager information appears at the end of the /etc/inittab file.
  • InfoPrint Manager is not supported with mutual takeover and cannot run in that environment.
  • The InfoPrint Manager information must be commented out in the /etc/rc.d/rc.local(RedHat Enterprise Linux/CentOS Linux) or /etc/init.d/after.local (SUSE Enterprise Linux) file by adding "#" in front of InfoPrint Manager lines. For example:
    #rcpd:2:once:/etc/rc.pd >/var/log/pd/rc.pd.out 2>&1 # InfoPrint Manager server
