Chapter 2: Installation Procedures

Preinstallation tasks

Before you install Unwired Accelerator, you must:

Verify that there is a “.” (dot) in the PATH environment variable.
Verify the $JAVA_HOME environment variable points to a valid JVM directory.
Verify that you have write permission on your login home directory, the directory where you install the software, and the /tmp/logs directory. If the logs directory does not exist, one is automatically created during installation.
Verify that you have 500MB free space in your temporary directory; otherwise, the installation fails.

If you do not have enough space in your /tmp directory, redirect the installer to use a different directory for temporary space.

The temporary directory to which you are redirecting must exist before you set the environment variable.

To redirect your temporary directory, enter:
```
./setupLinux.bin -is:tempdir /work/tmp
```
where /work/tmp is the directory of your choice.
Know the domain name of the machine where you are installing Unwired Accelerator. To find your domain name, contact your system administrator, or at a command prompt, enter:
```
domainname
```
Your domain displays, for example, sybase.com.
Install EAServer 5.2 EBF #12978 if you plan to install Unwired Accelerator in EAServer instead of Tomcat. See Appendix A, “Installing Unwired Accelerator in EAServer 5.2”.
