How to enable 64-bit gateway in Cognos 10.2

With IBM Cognos 10.2, IBM introduced 64-bit gateways to be more efficient. Well, this new features isn't enabled by default when you install IBM Cognos 10.2

As a result, there's a step that you would have to follow to make your gateways run in 64-bit mode.
You'll have to open command prompt on Windows operating system and terminal on Linux/UNIX system.

Navigate to <Cognos 10.2 Installation Location>\cgi-bin\ folder

On Windows, type and run

copyGateMod.bat 64bit

On Linux/UNIX, type

./copyGateMod.sh 64bit

As a result, the 64-bit gateway files are copied from the cgi-bin/lib64 directory to the cgi-bin directory.

The official IBM documentation for this is located here.

64-bit mashup: Cognos on Websphere Application Server

My earlier blog post about integration of Cognos with Websphere Application Server was based on 32-bit versions. Recently, someone contacted me as they were facing problems because they had 64-bit versions of both Cognos and Websphere Application Server (WAS that we call, for short).

It was showing some CAMCrypto.dll error. I reviewed the steps they had followed (actually they followed steps from my blog-post ;) ). So, I thought of putting this little post about initial analysis.

Whenever you are trying to run Cognos over Websphere Application Service, please

1. Make sure both are using same version of java, otherwise it will cause unacceptable behaviour.
2. Make sure you've copied bcprod*.jar (and db2 jars, if using db2 as Content Store) into <java>/lib/ext.
3. Double check the ports used by Websphere profile and Cognos environment in Cognos configuration.

Well, this was all correct. There's one small change for playing with 64-bit versions. In step 23, of deploying Cognos over WAS, change PATH to point to <your Cognos installation directory>\bin64 instead of <your Cognos installation directory>\bin for 32-bit versions.


64-bit versions lets your Cognos use more memory than 2Gbyte limitation of 32-bit JVM. So, that you could have more resources for your Cognos.

Let me know, if you still face issues.
