Cenário: EE 12.1.0.2.0OEL 6.5 standloneInstance em shutdown Me deparei com um cenário que o cliente não tem backup (físico, lógico, hot, cold, full, incremental, anything), também não possui nenhum plano de contigência... Pois bem, tentei realizar o seguinte procedimento:
1- Criei um pfile a partir do spfile 2 - alterei o paramentro undo_management para manual 3 - startup mount usando o pfile criado e alterado 4 - coloquei o datafile de UNDO em modo offline drop 5 - Quando tento abrir a base, para depois dropar a tablespace e criar outra, me gera o seguinte erro: ERROR at line 1:ORA-01092: ORACLE instance terminated. Disconnection forcedORA-00604: error occurred at recursive SQL level 2ORA-00376: file 4 cannot be read at this timeORA-01110: data file 4:'/u01/app/oracle/oradata/<INTANCE_NAME>/datafile/o1_mf_undotbs1_d2kfszv2_.dbf'Process ID: 5030Session ID: 237 Serial number: 55395 Também já realizei o procedimento antes de tentar abrir o database, mandei um shutdown immediate para baixar a instancia de forma sincronizada, e repeti os passos, porém também sem sucesso. O mesmo erro é gerado.
