Merge Result<br />
All entities could<br />
be merged<br />
without any<br />
problems<br />
3 entities which<br />
were out of the<br />
scope of the merge<br />
are merged<br />
nevertheless since<br />
they are referenced<br />
from other merged<br />
entities<br />

Strong and Weak references<br />
• Strong references include, for example:<br />
– References between a map and its associated axes,<br />
– References between typedef chains,<br />
– References between an array and an enum<br />
• To prevent structural impact on the destination data pool, definitions have to<br />
be excluded from the merge if they contain a strong (mandatory) reference<br />
to a "missing" entity. This is necessary in cases such as:<br />
– Map - axis is referenced but missing<br />
– Instances - element type is referenced but missing<br />
– Instances - memory type is referenced but missing<br />
– Struct / union instance - struct / union type is referenced but missing<br />
– Arrayed instances or structure type - #define is used as array index but<br />
missing<br />
• Weak references include, for example:<br />
– The reference of an online instance and its format string<br />
• Weak references can easily be discarded during the merge because their loss<br />
has no significant impact on the destination data pool.<br />

Miscellaneous<br />
How to delete a configurationUnit ?<br />
Configuration Units (GRL files) can be deleted by:<br />
• either merging an empty GRL file into the database<br />
• or by using the new “Delete ConfUnit” functionality of<br />
V4.1.0Update1<br />
Using CompareMerge in command line<br />
- Compare two databases and generate a difference file in *.htm<br />
