How do you manage the mountpoints when applying service with SMP/E? I am planning on discussing this at a BOF at SHARE next week, and I'd appreciate any thoughts that you have. I have a PMR open with IBM also.
All of the documentation simply says to mount the alternate HFS at /service, but I don't find that to be a very adequate solution. To me it is akin to running SMP/E with a PROC that includes DD statements for every target data set that specifies the target volumes, and it is asking for trouble. My preference is to use Automount to manage /service and set the PATHs in my DDDEFs to /service/IPLVOL/... where IPLVOL is the first sysres for the target zone. Automount would then mount OMVS.IPLVOL.ROOT as needed. In the old days, with only one HFS per target zone, this worked fine. Now that we have other products broken out into their own HFS, it becomes a little more complicated. For example, Java is designed to be mounted at /usr/lpp/java/ and the DDDEF PATH is to be -PathPrefix-/usr/lpp/java/J1.4. Since I am automount managing /service/ I need another place to mount the Java HFS for SMP/E. I set my automount policy to manage /service/mvs with the corresponding change to the PATHs to /service/mvs/IPLVOL/.... To provide a mount point that I can use for Java, I also manage /service/java and changed the path to /service/java/J1.4. Unfortunately, this does not work, because when it comes time to run AJVSCRPT, it expects the path to be of the form -PathPrefix-/usr/lpp/java/J1.4. My solution to this was to create a /usr directory in the Java root. Within that directory I created a lpp directory with a symbolic link at /usr/lpp/java in the Java HFS. This symbolic link has a value of "../.." (without the quotes). The result is that AJVSCRPT can find /service/java/IPLVOL/usr/lpp/java/J1.4. This allows everything to work. When I clone my target zone the /usr/lpp/java structure that is in the Java HFS gets copied along with everything else. There are ZONEEDITs to fix the DDDEF PATHs and I don't have to manually ensure that the correct HFSes are mounted for SMP/E. I think that XML, Host on Demand and MQ Series have similar requirements, but I have not spent much time investigating them yet. The PMR that I have open is against Unix System Services, but I think it might more appropriately be against SMP/E. The SMP/E manuals have numerous references to /service/usr/lpp/ without giving any hint of how to manage the mounting of the HFSes needed when applying service. I have looked at the AJVSCRPT script and it looks to me as if the limitation of using -PathPrefix-/usr/lpp/java is a result of the way that SMP/E calls the script. Any thoughts would be greatly appreciated.
