Hello Alexey,
as if i tried different things i found an unusal way to solve that problem. Now
i wanted to ask you (and the whole group) what side-effects can (or will) be
caused by this procedure.
- i dropped the idexes (INDEX_20 & INDEX_26)
- i modified the RDB$RELATIONS table to remove the SYSTEMFLAG off of the
RDB$COLLATIONS
- after that i was abled to drop that corrupt RDB$COLLATIONS table
- i disconnected the database
- i reconnected the database and received an error (missing table / some
relations)
- i executed a script to rebuild the RDB$COLLATIONS table ant its indexes
- i modified the RDB$COLLATIONS table to add the SYSTEMFLAGS for that table and
its indexes
- then i re-inserted the 148 datasets that were originally in the
COLLATIONS-table
Now, backup/restore/everything else is working fine. Or it seems so.
All of that has been done in an testing-environment!
Now i need to know if there is anything that i should be worried about. If so:
where`s my mistake?
Greetings from Germany!

Hello Maik,

This is a database corruption, but our IBFirstAID will not help in this
case, since it's a system index problem.
You can contact support at ib-aid.com to get professional recovery
support through remote desktop.
