Check current size of /tmp space like this:
[root@primary01 /]# df -g /tmp
Filesystem GB blocks Free %Used Iused %Iused Mounted on
/dev/hd3 3.00 2.49 18% 71 1% /tmp
It's 3 GB only.
Since we have more and more demands on /tmp space of this server, we should raise the size of /tmp, say 10GB.
[root@primary01 /]# chfs -a size=10G /tmp
Filesystem size changed to 20971520
Check the size of /tmp once again.
[root@primary01 /]# df -g /tmp
Filesystem GB blocks Free %Used Iused %Iused Mounted on
/dev/hd3 10.00 9.49 6% 71 1% /tmp
