Нашел только одну грамотную статью в тему — One Long and Nasty Recovery. Причина падения — попытка Oracle откатить (rollback) данные не зафиксированных транзакций (uncommitted data). Далее автор пытается разобраться в причинах крушения базы при применении данных из UNDO (подробно статью дальше не читал, т.к. не было времени).

Я проверил все файлы с помощью dbv. Только одно табличное пространство оказалось битым — SYSAUX. Поэтому я для себя сделал вывод, что при попытке отката транзакции идет обращение именно к этим битым блокам и здесь экземпляр почему-то падает, хотя по идее не должен (но это на совести программистов).

Предлагается использовать событие event=»10513 trace name context forever, level 2″, чтобы отключить восстановление транзакций.
©Bobrovsky Dmitry

SQL> conn sys/passwd@xe as sysdba
SQL> shutdown immediate;
SQL> ALTER SYSTEM SET EVENTS '10513 trace name context forever, level 2';
SQL> startup

Но это не помогло БД всё равно падала. Далее то что называется «чуйка» 🙂 При просмотре лога меня смутило «sessions = 49«. Чисто интуитивно добавил еще установку sessions и processes. (Если  ALTER SYSTEM SET EVENTS не срабатывает, можно добавить параметр event в spfile).

SQL> conn sys/passwd@xe as sysdba
SQL> shutdown immediate;
SQL> startup mount
SQL> alter system set processes=150 scope=spfile;
SQL> alter system set sessions=170 scope=spfile;
SQL> shutdown immediate;
SQL> ALTER SYSTEM SET EVENTS '10513 trace name context forever, level 2';
SQL> startup mount
SQL> alter database open

Это помогло и база запустилась. Но при этом есть данные не зафиксированных транзакций и битые блоки в SYSAUX. Т.к. рабочая схема находится в ТП USERS и она небольшая, то я решил не заморачиваться, а слить дамп с рабочей схемы, создать новую БД и залить его туда, а эту БД удалить.
