If you wonder what is the password for Oracle Internet Directory(OID) user cn=orcladmin after OIM installation, well, it is exactly the same as ias_admin password specified during installation of OIM. If you really want to reset the password, use included utility resetiASpasswd.sh in $ORACLE_HOME\bin as follows:

First make sure your environment is setup properly for OIM home. (ORACLE_HOME param.)
$ORACLE_HOME/bin/resetiASpasswd.sh cn=orcladmin your_new_pass $ORACLE_HOME

To reset OID password use oidpasswd utility as Robbert pointed out.

If you’ve just upgraded from 9i to 10g, and you are using unsupported collection return types in pipelined functions you are no longer able to compile the code due to a more restrictive 10g compiler. Your pipelined functions compiled just fine on 9i. You are unable to compile the functions with the following error message PLS-00630: pipelined functions must have a supported collection return type. If rewriting huge amounts of code is not an option for you, this event will allow you to compile the code:

ALTER session SET events= '10946 trace name context level 4';

Microsoft Windows (1.7 GB)
Linux x86 (1.7 GB)

You can use the following query to determine your log switch frequency past 7 days (by hour):

Our Linux OAS should be started using the same NLS_LANG as client is using, in our case NLS_LANG=SLOVAK_SLOVAKIA.EE8MSWIN1250

export NLS_LANG=SLOVAK_SLOVAKIA.EE8MSWIN1250

cd $ORACLE_HOME/opmn/bin

# restart OAS
./opmnctl stopall
opmnctl: stopping opmn and all managed processes...

./opmnctl startall
opmnctl: starting opmn and all managed processes...
