There may be a need to use a silent install for Linux, such as needing to install multiple servers without using the GUI or needing to install SRAdmin into a custom location.
When following the documented steps for a silent install of SRAdmin the install fails.

I perform the following command:
./srainstall.bin -f /opt/sp-media/sradmin-properties

With the following lines in my properties file:

But the only files I get in my /opt/spectrum directory is:

4.4M ./sradmin/Uninstall
188M ./sradmin/jre
192M ./sradmin
192M .
Spectrum 10.1.x
Spectrum 10.2.x
Spectrum 10.3
There is a need to create a temporary installation directory and export it as a variable of IATEMPDIR.

1. Create a temp directory for the installer under tmp and assign permissons
cd /tmp
mkdir sradmin
chmod 755 sradmin

2. Export the IATEMPDIR variable to the temp location made from step 1.
export IATEMPDIR=/tmp/sradmin;

3. You can verify that the variable exists by echoing the variable

If you run the install again it should be successful.

The documentation should be updated, but this techdoc is to be used interim
