Hi All,
  I'm installing an 841 distributed environment on 64-bit Linux and can't get my CM to start up.  I keep getting

INFO, "[main]", "Silent Execution Mode (start)"
EXEC, "[main]", "Loading configuration file"
SUCCESS, "[main]", "Completed successfully."
ERROR, "[main]", "IBM Cognos Configuration was unable to successfully use the cryptographic information with the current Java Runtime Environment located in /<path>/cognos841/bin/jre/1.5.0.

The appropriate JAR files must be installed in the Java Runtime Environment referred to by JAVA_HOME (using jre1.5.0_12). For more information, see the Installation and Configuration Guide.
[Validation] CAM-CRP-1057 Unable to generate the machine specific symmetric key.

this seems to say cognos can't find the bcprov jar but its in my lib/ext directory with 777 permissions.

Any ideas?

mpflug,

on my AIX machine, when I installed Cognos. It didn't install a Java Runtime with it like in Windows installation. That's why I configured the JAVA_HOME to point to another  Java Runtime that was installed by another IBM product and then copied the bcprov-jdknn-nnn.jar file into the LIB directory under this path and then everything worked fine.

I am not sure if this will be the case for Linux, but it may give you a clue.

Another thing that come into my mind now, the beprov file is marked with version 1.4 and you have Java 1.5 , it may be the problem. You can also check this.

Hope this could help.
