DELETE MOL-file data in a repository

For each DBMS version Mega provides a Mol-file.

 

Can we delete the old version(s) of a DBMS from our repositories without risk ?

I mean, can we delete the PACKAGE (and CLASSES)  corresponding to a certain DBMS version we do not use anymore, because we use a more recent version of the DBMS ?

 

Can someone give me some hints&tips how I can realise this ?

 

thanks

Hello m van poucke

 

For each RDBMS version provided by MEGA, there should be a MEGA option

Ex: Options > Data modeling > SQL Generation > Oracle 9i

If this option is inherithed and you disable it at MEGA environment level, it should not be displayed in the properties of a database object.

 

If ou delete a package containing class-datatypes, there is a risk to impact column datatype values.

Theses values are computed dynamically from the definition of RDBMS version and the corresponding packages.

For example, if you delete the package 'MEGA:: Standard:: Types:: Sql:: Oracle 9i', you may impact the columns of the database that are configured with target RDMS = Oracle 9i.

 

More generally, if for some reasons, links exist around theres packages and their classes, you may loose information.
