If mounting the /tmp directory is not an option, a temporary directory could be created as a workaround.
1) Create a new tmp directory:
# mkdir /tmp2
2) Ensure it has proper permissions:
# chmod 755 /tmp2
**optional based on install method**
3) Customize your RPM package to reflect the new tmp directory.
# customize_eac_rpm -t /tmp2
4) Install the program
5) You can remove the /tmp2 directory after the server reboots.
