db2wdog

P: n/a
Hello Folks

I have a simple question. In db2 v7, AIX platform, is db2wdog or
which process is responsible for restarting db2 automatically in case
of a instance problem?
And in the case of db2 process being restarted automatically by
db2wdog, would the process skip instance userid .profile? Im having
some problems with environment variables being 'lost' when calling TSM
api and this is making me bored a lot. I have added the export for
DSMI_CONFIG/DIR/LOG to userprofile file in sqllib dir expecting to
avoid this problem

Anyone have some insights/directions about how db2 v7 are restarted
automatically in case of a instance crash to share?

Thanks a lot
Alexandre

The automatic restart isn't done by the watchdog process.
Check the DB2 Admin Guide and look for db config parm "autorestart":
http://publib.boulder.ibm.com/infoce...0/db2d0140.htm
and
http://publib.boulder.ibm.com/infoce...2d0/cfgdbs.htm

HTH.

And when you are planning to upgrade to a supported version (v8/v9), you
would want to have a look at the Fault Monitor facility:
