Oracle 11g Grid: Using EMCLI , A command line Grid Control Interface

Posted By Sagar Patil

The Enterprise Manager Command Line Interface (EM CLI) enables you to access Enterprise Manager Grid Control functionality from text-based consoles (shells and command windows) for a variety of operating systems. You can call Enterprise Manager functionality using custom scripts, such as SQL*Plus, OS shell, Perl, or Tcl, thus easily integrating Enterprise Manager functionality with a company’s business process.

1. Requirements : Before installing EM CLI, you will need the following:
Java version 1.6.0 or greater
Workstation running Solaris, Linux, HPUX, Tru64, AIX, or Windows with NTFS (client installation)

2. Download the EM CLI Kit to your workstation.
If you have Grid control in place use URL http://%Gridcontrol%HOST%/em/console/emcli/download

3. Install EM CLI Client.

You can install client portion of EM CLI in any directory either on the same machine as the OMS or on any machine on your network (download the emclikit.jar to that machine).
Run “java -jar emclikit.jar client -install_dir=<emcli client dir>”

4. The CLI must be set up and connected to an OMS

Execute “emcli help setup” from the EM CLI Client for instructions on how to use the “setup” verb to configure client for a particular OMS. Setup emcli to work with the EM Management Server (OMS) specified by the -url argument. Issuing the “emcli setup” command with no arguments will show current OMS connection details.
