OHS 11 and configuration errors

with 2 comments

While trying to work out some rewrite rules for UCM on OHS (Apache) I noticed a new feature that I didn’t notice before. Back in the good old OAS days (when the air was clean and sex was dirty) I was used to check my apache configuration like this:

apachectl configtest

This would prevent Apache from crashing upon restart from opmn. When moving to 11 (and WebLogic) I stopped doing this (could get the configtest to work), which ment I have to doublecheck my configurations before setting them online.

Anyway, constructing rewrite rules is difficult (to me), chances are that you make a mistake while constructing the rule. So when I made a configuration error I noticed this:

$ /u01/app/oracle/admin/instance1/bin/opmnctl restartproc process-type=OHS
opmnctl restartproc: restarting opmn managed processes...
================================================================================
opmn id=testbox.area51.local:6701
0 of 1 processes restarted.

ias-instance id=instance1
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
——————————————————————————–
ias-component/process-type/process-set:
ohs1/OHS/OHS/

Error
–> Process (index=1,uid=893024996,pid=14351)
Process restart failed.
Process is still alive — check configuration.

Log:
/u01/app/oracle/admin/instance1/diagnostics/logs/OHS/ohs1/console~OHS~1.log

Now that’s interesting. Oracle added a new feature: check the configuration before restarting Apache. The “Process is still alive — check configuration.” is new to me. Didn’t read this is the docs, still nice to know.

Hope this helps.

  1. Very interesting! That’s quite smart thinking from Oracle and is a good example of how they can add value when re-packaging Apache 2 into their “web-tier” product.
