Oracle cleanup - flyway fails on tables that have Flashback enabled

[awal11]

I have a schema with tables set to use Oracle Flashback/Total Recall (full audit implemented completely on database side).

After I create the tables with command like

ALTER TABLE USERS FLASHBACK ARCHIVE FDA_TRAC

Oracle creates 'magic' tables like SYS_FBA_HIST_61527 that flyway fails to delete automatically, throwing:
ORA-55622: DML, ALTER and CREATE UNIQUE INDEX operations are not allowed on table "SCOTT"."SYS_FBA_HIST_61527"

To be able to clean the schema one would need to execute

ALTER TABLE USERS NO FLASHBACK ARCHIVE

before attempting to delete anything.

So how should I help:

• if this pull request DbSupport extensibility (allows for overriding doClean(), etc.) #629 gets accepted - I guess I don't need to do anything - is there a chance for it?
• I could update OracleSchema.java to detect and 'NO FLASHBACK' appropriate tables automatically - would such patch be accepted?
• if so - should I add a test case for it? It will end up @Ingored as Flashback not enabled in most oracle instances and not very popular.

Thanks for your report and your offer.

A pull request with an @ignore test case would really be ideal. This way not only you, but all other users of Flyway will also benefit from this.

Looking forward to your contribution!
