IBM Tivoli Composite Application Agent for J2EE, Version 7.1.1

Silent installation and uninstallation

You can use the Installer to install ITCAM Agent for J2EE in silent mode. To do this, modify the sample file provided on the installation DVD, and then run the installer from the command line.

To perform a silent installation, first you need to prepare the response file. Then, run the installer, supplying the name of the response file. A silent uninstallation does not require a response file.

Preparing the response file for the agent installation

To prepare a response file for installing the agent, perform the following procedure:

On the product installation image, in the top level directory, locate the silent_install.txt file.
Make a copy of this file, and open it in a text editor.

Modify the following property, if necessary. Do not modify any other properties.

Table 1. Agent installation response file properties
Response file property	Meaning
EncryptionKey	The 32-character encryption key used to secure password transmission and other sensitive data across your IBM® Tivoli® Monitoring environment. See IBM Tivoli Monitoring: Installation and Setup Guide for details about the encryption key.

Save the edited copy in a work directory, for example, as /tmp/silent.txt.

Running the Installer in silent mode

After preparing the response file for your installation and uninstallation, run the installer, specifying the path and name for the response file. Perform the following procedure:

Change to the directory of the installation image.
Invoke install.sh:
```
./install.sh -q -h ITM_home -p response_file_name
```
where ITM_home specifies the destination directory where the agent will be installed (by default it is /opt/IBM/ITM; you can use different destination directories to install several copies of the agent on the same host); response_file_name is the name of the response file you have prepared (with full path). For example:
```
./install.sh -q -h /opt/IBM/ITM -p /tmp/silent.txt
```

Attention: if you are performing an upgrade or maintenance level update, and the Monitoring Agent is currently running, silent installation will be aborted.

Performing a silent uninstallation

To uninstall ITCAM Agent for J2EE in silent mode, perform the following procedure:

Change to the ITM_home/bin directory.
Run the command:
```
uninstall.sh -f yj platform_code
```
