psgrep not found

[Mary Ann Lipa]

hi,
i am having problems with my cluster's config.
it says:
psgrep: not found
i checked customer.functions and the psgrep line seems OK..
i also looked for psgrep but i cant find it anywhere.
trying to work it with MCSG A.11.13 and SAP

please help...
thanks

which version of the SGeSAP toolkit are you using to create your SAP package?
I am not aware of a psgrep command

[Massimo Bianchi]

Neither i know of a "psgrep" command.

It may be an alias...

try issuing, from shell

alias | grep ps

and see.

Not knowing anything about SAP peculiarities, I simply would assume that psgrep is nothing more than an alias or a shell func definition by the user account that runs the SAP instance.
I further would assume that this alias or like is already defined in some (shell specific) dotfile in the sap user's $HOME.
Probably your package control script just needs to source this dotfile?

[Mary Ann Lipa]

thanks. i'll consult my sap guy.

Ah, found it.

I remembered we had a box that runs SAP.

Thereon I did this:


# swlist|grep -i sap
B7885BA B.03.07 MC/Service Guard Extension for SAP
PHSS_28733 1.0 OV DP5.00 patch - SAP packet
# swlist -l file B7885BA
# Initializing...
# Contacting target "warnow"...

/opt/cmcluster/sap/SID/startdb.sql
/opt/cmcluster/sap/customer.functions
/opt/cmcluster/sap/sap.functions

# grep -l psgrep $(swlist -l file B7885BA|grep /opt)
/opt/cmcluster/sap/customer.functions
/opt/cmcluster/sap/sap.functions

# grep alias\ psgrep /opt/cmcluster/sap/sap.functions
alias psgrep='ps -ef | grep -v grep'

There we got the culprit.
I think you must provide your customer_defined_cm{run|halt}_commands()
somehow with an invocation (probably sourcing) of this sap.functions file.

[Mary Ann Lipa]

Thanks Ralph..
got it now....
its just an alias..

[Ralph Grothe]

Mary Ann,

don't know if the basic SAP file layout is the same on most HP-UX boxes.

However I found on our's in one of the SG packages' directories this sapdbci.cntl file lingering.

Therein is a variable assignment that gives the path to the sap.functions.
Maybe this one is lacking in your installation?

# grep ^FUNC_FILE /etc/cmcluster/Z01/sapdbci.cntl
FUNC_FILE=${FUNC_FILE:-/etc/cmcluster/sap.functions}

It looks like this function was in the older versions of the SGeSAp Toolkkit, as it is no longer in the newer versions that I have.
You should find in the /opt/cmcluster/sap/sap.functions file that there is a line:
alias psgrep=`ps -ef | grep -v grep`
All this is doing is enabling later grep command lines to be shortened in htese scripts.
This is definitley in the B.03.06 release.
As I say, this no longer seem to appear in the later SGeSAP toolkit releases.
Checking my B.03.07 it is still htere, but in hte newer B.03.08 it is no longer there.
