Yes.... but there might be more to take into consideration
- if the error occured in spite of you did not upgrade some filesets or lpps
the firmware level is not necessarily the cause of the problem.
- IBM's helpdesk tends to make you upgrade the firmware level /oslevel if
problems occur because this is much easier for them. As long as a particular
error cannot be assigned to a particular error (i.e. that exactly this error
is known already and thus a solution exists) I would be cautious to upgrade
the firmware because of the two following reasons:
- if you upgrade the firmware level and you use an 'old' RML you might then
be forced to upgrade the operating system as a consequence. So if you go
this way make sure that you have the latest RML update at hand. Installing
an RML might again give you a chance to reboot.
- if you upgrade the RML you might be forced to install some patches for
Oracle...
You are getting the picture. So check you service contract whether it is a
conditio sine qua non that IBM will help only if you use the latest firmware
and if it is not kick their shinbone. However should you find out that
upgrading the firmware is your only chance then you are out of luck. As
Jurjen pointed out already you cannot have your car's wheels changed while
driving in circles round the garage. Coming to think about it: IBM says that
even an HACMP cluster is not suitable for true 24x7 - and you are running a
single server you cannot reboot over night or over the weekend? Hmmh, maybe
you can try a background reboot: # sync; sync; sync; reboot &
