Migration for XWIKI-7564: Manually change the SQL type of long binary columns from LONG RAW to proper BLOBs when the
underlying database is Oracle. More specifically, this migrator changes the attachment content and attachment archive
columns from LONG RAW to BLOB, and rebuilds the indexes on those tables afterwards. The columns must be switched to
BLOB since this is the expected column type when using the new mapping files. Rebuilding the indexes is needed
because changing a table's columns automatically invalidates the indexes on those tables, and with unusable indexes
any new insertion in those tables will trigger an exception.
- Since:
- 3.5.1
