The first time I had to find out what version of Oracle Application Server was running, I thought it would be a pretty straight forward task, but it’s not so straight forward as you’d first think, so I thought I’d blog it so I know for next time 😉
Some people check the $ORACLE_HOME/install/readme.txt file, which is fine for a fresh install, but doesn’t account for future updates.
The easiest way is to check the following on the server (where $ORACLE_HOME is your Oracle AS instance home):
grep Version $ORACLE_HOME/config/ias.properties Version=10.1.2.3.0
You could also check the following URL for your installation:
http://[hostname]:[port]/emd/console/aboutApplication
…or for a more detailed overview of the various Oracle AS components, and applied patches, you could check the inventory:
$ORACLE_HOME/OPatch/opatch lsinventory -detail
