Install Linux Dialog Instance w/ an AIX Xentral Instance.

[Former Member]

Has anyone Been able to install a Linux Dialog instance onto an existing AIX CI?

How have you resolved the isses of the Binaries Syncing from the AIX Sapmnt? I have altered the Startup Profile for the app server so that the DIR_CT_DIR point to /sapmnt/BQ1/exe/uc/linuxintel (instead of $(DIR_EXE_ROOT)/run).

But there are stil scripts that point to the Executables on the /sapmnt/<SID>/exe area.

I would assume it would be best to point all the Directories to /usr/sap/<SID>/D00/exe (where SAPCPE moves the executables to). The question is, how do I modify everything to point there?

These give me tons of good options!

We have the same system constellation and are currently installing DIs (SLES 10 / x86_64) too. We never had such a problem and so i don't "understand" the problem...

Which problems do you have with syncing from CI to DI; How does this happen, what are the effects...

We didn't mount the /sapmnt/<SYSID>/exe from CI and DI globally. They are local.

We mounted the SAPMNT Globally so the App server could get all the params, Job Logs, etc from sapmnt.

The way the Directory structure for unix/linux works, SAPCPE syncronizes from /sapmnt/<sid>/exe There are also some scripts that point there. automatically. Like running startsap. Even after installing the correct kernal on the /usr/sap/<sid>/exe/run area it will point to /sapmnt to run R3trans....

I have tried changing the DIR_CT_RUN variable in Both the start & system profiles. So far my success has been limited.

Can't you simply create a symlink from /usr/sap/<SID>/D00/exe to /sapmnt/<SID>/exe ?

Do you mean from /sapmnt/<SID>/exe to /usr/sap/<SID>/D00/exe?

Since /sapmnt/<SID>/ is an NFS Mount from the CI, would that affect anything on the CI? Or would the Sym link only occur Locally?

My other option would be to not mount /sapmnt/<SID> from the CI.. instead to mount /sapmnt/<SID>/global & /sapmnt/<SID>/Profile separately & leave /sapmnt/<SID>/exe as a Local File system.

Hi,

another simple approach is to have platform dependent folders like:

/sapmnt/SID/exe_aix
/sapmnt/SID/exe_linuxx86_64
/sapmnt/SID/exe_linuxia64
...

which you link to /usr/sap/SID/SYS/exe/run or /usr/sap/SID/Instance/exe

You can also have several of them with some kind of revisioning of the patchlevel in case the latest patchlevel does not work:

/sapmnt/SID/exe_aix_pl86
/sapmnt/SID/exe_aix_pl112
/sapmnt/SID/exe_aix_pl146

Your "other" option is the way I would do it, mount global and profile directory separately then symlink as I mentioned in my previous post or additionally as Hannes has pointed out.

I would export a separate directory on the CI and mount that as /usr/sap/<SID>/D00/exe on the DI.
