[mapguide-users] DB XML Error and Packages

[David Bowen]

I'm encountering an issue when trying to load packages using Maestro. For
example, I'm attempting to load the package created from our Production
environment into the Development environment and I get the following errors:

The remote server returned an error: (559) MgDbXmlException.:
An exception occurred in DB XML component.
Error: DB_BUFFER_SMALL: User memory too small for return value

Based on previous threads, I've attempted to increase the following
parameters in the serverconfig.ini file but have had no success.

#SessionDBXMLPageSize = 0.5
SessionDBXMLPageSize = 1.0
#SessionDBPageSize = 2
SessionDBPageSize = 4
#SessionLogBufferSize = 1
SessionLogBufferSize = 5
#LibraryLogBufferSize = 12
LibraryLogBufferSize = 24
#DBXMLPageSize = 32
DBXMLPageSize = 64
#DBPageSize = 32
DBPageSize = 64

Has anyone else encountered this issue and have figured out a solution?

Thanks,
David
