Adaptive Server stores data generated by dbcc checkstorage in dbccdb. You should periodically clean up dbccdb by using sp_dbcc_deletehistory to delete data for the target database that was created before the date you specify.
When you delete a database, you should also delete from dbccdb all configuration information and dbcc checkstorage results related to that database. Use sp_dbcc_deletedb to delete all database information from dbccdb.
