Multiple Instance Limitations

The following limitations apply when running multiple instances of TIBCO iProcess® Objects Servers:

•

The same user logging into multiple instances consumes one license per instance. This is because each instance must create a separate SAL session for the user.

•

An SWXList (TIBCO iProcess Objects) or pageable list (TIBCO iProcess Server Objects) of work items or predicted work items is tied to a specific server instance. If an SWXList/pageable list of work items or predicted work items is created, that list can only be accessed on the server instance where it was created. This is not just limited to getting the work items on an SWXList/pageable list, but also to the method calls on work items obtained from an SWXList/pageable list. However, all other operations can be performed against any instance in the cluster (bearing in mind the licensing limitation above).

•

Since each instance caches the procedures, user, groups, roles, attributes, tables, and lists, more memory is required system-wide due to duplication of this information.
