10g upgrade problem

Question

We upgraded from BPM 5.7 to OBPM 10g and the installation went smoothly. However, when we published our projects, which had been converted from 5.7 code to 10g code, and then deployed the projects, we got the CannotUpdateEngineExternalVariablesException. Anyone experienced similar problems?
Here is the full stack trace from webconsole.log.

Answer 1

Hi,
Are you able to successfully publish a project that doesn't have a project variable in it?
If this is the case, could you ask the DBA if the database user created for the Engine has "ALTER" privileges? If you're able to publish a project that does not have a project variable (called "external variables" in previous releases) successfully, but run into this error when publishing a project that does have a project variable this might be the case. Publishing a new project with a new project variable will result in an additional column on the PPROCINSTANCE engine table for each project variable being added.
Hope this helps,
Dan
