Updating an agent on UNIX and Linux operating systems

This scenario describes the procedure to update an agent on UNIX operating systems.

To update the agent, complete the following steps:

Note: For a description of the operating system commands, see Command reference.

Go to the Downloads section on the Your subscription page.
Go to the directory where you saved the compressed agent update files, in this example, /SaaSAgent.
Extract the agent update files to this directory:
- For Linux for IBM System z: extract the SCWA-SaaS_LINUX390.zip
- For Linux 32 bit operating systems: extract the SCWA-SaaS_LINUX_I386.zip
- For Linux 64 bit operating systems: extract the SCWA-SaaS_LINUX_X86_64.zip
- For AIX operating systems: extract the SCWA-SaaS_AIX.zip
- For HP-UX operating systems: extract the SCWA-SaaS_HPIA64.zip
When the extraction completes, the following directory structure is created in the SCWA-SaaS directory on your computer:
From a shell on the computer on which you want to update the product, log on:
- As root, if the agent was installed by the root user.
- Using the login of the user who installed the agent, if the installer was a non-root user. To find the login name used by the installer, see the InstallationLoginUser parameter in the JobManager.ini configuration file available in TWA_home>/TWSDATA/ITA/cpa/config.
To update the agent using the default settings, run the following command from the directory where you downloaded the agent update files:
```
./installAgent.sh -update [-uname user_name] -acceptlicense yes
```
Where:

-update

Updates the agent on the workstation where you run the command.

-uname user_name

The user name of the agent, defined at installation time. If you are logged in as a non-root user, you can omit this keyword, since user_name equals the login name.

-acceptlicense yes|no

Specify whether or not to accept the License Agreement. If you specify no, the update exits without performing any action.

After a successful update, proceed with the update of another agent if necessary.

If the update did not complete successfully, an error is displayed on the screen. Correct the error as described in the Operator Response error that you can find in the twsinst_operating_system_user_name^version_number.log file located in TWA_home>/TWSDATA/installation/logs, and rerun the update.
