Netbackup 126.96.36.199 in need of more space in /tmp
I have an NetBackup 7.5 and trying to upgrade to 188.8.131.52 (HPUX ia64). During the installation it says me I have about 1.2 GB of free space in /tmp and NetBackup needs about 2.4 GB in /tmp.
The problem is, my /tmp is a fixed size, about 1.4GB in total. Can I redirect where NetBackup can extract the files to another directory with more disk space?
