ITSM installation Undefined value as a HASH

[jesupi]

Dear all,

I successfully installed OTRS 2.4.7 on Centos 5 on an Oracle database.

The problem is when I installed OTRS::ITSM 2.0.3. I used the Bundle opm from the package manager, but when the process finished I got this page:

-------------
Software error:

Can't use an undefined value as a HASH reference at ../..//Kernel/System/ITSMChange.pm line 1923.

For help, please send mail to the webmaster (root@localhost), giving this error message and the time and date of the error.
--------------

Now each page I try to access, I get the same error. Then I'm blocked.

Any ideas?

Thank you in advance,

Jesús

We have the same problem with otrs 2.4.8.
Even trying to install every single pkg when you install ITSMChangeManagement the same problem occurs.
Our system is CentOS 5.5 and oracle 10.

I had the same problem with my RedHat 5.5 box and Oracle 11gR2
Do not forget to put these lines in Config.pm
The important one is the NLS_DATE_FORMAT. I think it has something to do with the session and the time stamp, which OTRS posts in Oracle
Below are the lines i put in Config.pm
Hope it helps

$ENV{NLS_LANG} = "american_america.el8iso8859p7";
$ENV{ORACLE_HOME} = '/home/oracle/instantclient_11_2';
$ENV{NLS_DATE_FORMAT} = 'YYYY-MM-DD HH24:MI:SS';
