Installing products into the file system
When you install other products into the file system, create new directories where the files associated with the new product will be installed. You might also need to create a new file system for the new product and mount it to a new directory.
To help you decide how many file systems you need, see the information about product sets in the topic that discusses placing data sets on specific volumes in z/OS Planning for Installation.
The procedures in this topic apply to those installing products into the /etc file system on a production system.
Because /etc is a symbolic link, it cannot receive product or service code. You need to run jobs that change /etc to a directory, install the code, and change /etc back to a symbolic link. The jobs you use are in SYS1.SAMPLIB.
- Mount a clone of the root file system at the /service mount point.
- Run the sample job BPXISETD to convert the /etc symbolic
link to a directory. Pass the /etc as a parameter
to the REXX exec.
Optionally, you can use BPXISJCL to submit the job in the background.
- Mount the /etc file system.
- Install the products or service.
- Unmount the /etc file system after everything is installed.
- Run the sample job BPXISETS to convert the /etc back to a symbolic link.
