Starting installation

To Start installation• # /srbusr/srb/install.pl

Some minor issues with the script and its workaround• It requires postgresql tar file as postgresql-7.3.3.tar without the

letters ‘base’ as it expects installation dir name to be same as tar file name.

• Some source files expect java to be located at /usr/local/apps/jdk1.4.1/bin – Hence softlinks may need to be created

• Keep the Srb Admin name same as unix account eg srbusr
