[oracle@SIT130093 ~]$ oerr ORA 0039200392, 00000, "log %s of thread %s is being cleared, operation not allowed"// *Cause:  An operation encountered this online log in the middle of being//          cleared.  The command that began the clearing may have terminated//          without completing the clearing.// *Action: If the clear command is still executing then wait for its//          completion. If it terminated then reissue the clear command, or//          drop the log.

解决方案

SYS@cams>select GROUP#,STATUS from v$log;     GROUP# STATUS---------- ---------------- 1 CLEARING 3 CLEARING 2 CLEARING_CURRENT SYS@cams>alter database clear logfile group 1; Database altered. SYS@cams>alter database clear logfile group 2; Database altered. SYS@cams>alter database clear logfile group 3; Database altered. SYS@cams>select GROUP#,STATUS from v$log;     GROUP# STATUS---------- ---------------- 1 UNUSED 3 UNUSED 2 CURRENT

RMAN> alter database open resetlogs; database opened

如果使用clear logfile的方案不好使，可采用如下方案：

Recreate the controflile with the RESETLOGS option.1) Get the controlfile trace from below command :SQL> ALTER DATABASE BACKUP CONTROLFILE TO TRACE AS '/tmp/control.sql' resetlogs ;2) Modify the CREATE CONTROLFILE  script /tmp/control.sql and ensure that all directories for the online redo logs exist and Oracle has permission to write to it3) Create the controlfile in NOMOUNT state :SQL> STARTUP FORCE NOMOUNTSQL> @/tmp/control.sqlcontrolfile created4) Run a fake recovery :SQL> RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL ;Type  when prompted5) Open with RESETLOGS option:SQL> ALTER DATABASE OPEN RESETLOGS;
