Today I was asked to assist in troubleshooting an Oracle Client (10g) installation. The installation halted very quickly with a java.lang.NullPointerException:

My collegue that is working with me on the current project was packaging another application that uses Oracle.
The interesting thing about it is that he ran into the same error I did: the Oracle client tries to create (and access) an Object in the Global namespace.
But he got an entirely different error message:
To confirm it was the same issue I gave a test user the Create Global Objects privilege and after logging on again the problem went away.
So I applied the same fix that I wrote about yesterday in Redirect Global Object to Local Objects (aka fix that bad app!) to this application and it worked nicely!

Today I was working on Unattended Installation of an Application called SmartDocuments.
The application seemed to behave nicely on a Multi User (Citrix/Terminal Server) environment: it writes user configuration to the user part of the registry and writes configuration files in a user accessible path.
When testing with a normal user account I ran into a problem though, I got an Oracle ORA-01019 error message:
The English message is ORA01019: unable to allocate memory in the user side.

Last week I needed to an unattended installation of the Oracle Client, in my case version 10.2.0.1.0.
Oracle has a record switch that allows you to record an installation and generate a response file using: setup -record -destinationFile response_file_name. This is documented here.
When you are finished you can use this response file to perform the unattended install, eg setup -silent -responseFile response_file_name.
There is a problem though, the installer (setup.exe) launches a java based installer and immediately returns.
This was a problem for me since I cannot deploy a dependant application if the Oracle install hasn’t finished yet.
I did some googling and found a lot of questions about this subject and saw a common resolution where a script is watching a certain file that is creating when the installation has finished in a loop.
I figured there should be a better wait so I to a closer look at the installer with Ida Pro. I noticed that setup.exe launches another exe. called oui.exe (Oracle Universal Installer) which in turn launches Java.
