Whenever adop prepare phase is initiated, a new patch edition is created in the database.During Online patching (ADOP) : An additional column ZD_EDITION_NAME is populated in the seed tables.As we do more online patching cycles, the number of entries for database editions will increase. This affects system performance and also increases cleanup time.When the number of old database editions reaches 25 or more, you should consider dropping all old database editions by running the adop actualize_all phase and then performing a full cleanup.
To drop older database editions, follow the below steps:
$ adop phase=prepare
$ adop phase=actualize_all
$ adop phase=finalize finalize_mode=full
$ adop phase=cutover
$ adop phase=cleanup cleanup_mode=full
