Oracle Study之--RMAN启用block change tracking错误

Oracle Study之--RMAN启用block change tracking错误

系统环境：

  操作系统： RedHat EL6

  Oracle:   Oracle 11g R2

Target DB:    prod

Catalog DB:   orcl

      在使用rman备份做增量备份后，启动“block change tracking” 出现了ORA-600错误！

案例分析：

1、启用block change tracking

11:23:43 SYS@ prod>alter database enable block change tracking using file '/home/oracle/blk.trc' reuse;

Database altered.

告警日志：
alter database enable block change tracking using file '/home/oracle/blk.trc'
Block change tracking file is current.
Starting background process CTWR
Tue Apr 07 11:36:55 2015
CTWR started with pid=33, OS id=5576
Block change tracking service is active.

2、通过rman建立备份脚本

[oracle@rh7 dbs]$ rman target / catalog rman/rman@orcl

告警日志：

     从日志可以看到CTRW进程关闭了Instance！

3、停止使用block change tracking

11:31:33 SYS@ prod>alter database disable block change tracking;

Database altered.

Elapsed: 00:00:01.13

告警日志：

alter database disable block change tracking
Tue Apr 07 11:31:50 2015
Block change tracking service stopping.
Stopping background process CTWR
Deleted file /home/oracle/blk.trc
Completed: alter database disable block change tracking
Tue Apr 07 11:34:36 2015

再通过rman建立备份脚本：

[oracle@rh7 dbs]$ rman target / catalog rman/rman@orcl

Recovery Manager: Release 11.2.0.1.0 - Production on Tue Apr 7 11:29:41 2015

Copyright (c) 1982, 2009, Oracle and/or its affiliates.  All rights reserved.

connected to target database: PROD (DBID=239333010)
connected to recovery catalog database

RMAN> create global script global_del_obso comment 'A script for obsolete backup and delete it'
{
2> 3>  crosscheck archivelog all;
4>  delete noprompt expired archivelog all;
5>  allocate channel ch2 device type disk;
6>  delete noprompt obsolete recovery window of 15 days;
7>  release channel ch2;
8>  }

这是备份脚本建立成功！

 注：

       在后面又出现了一样的错误，在操作系统下删除了trace文件“blk.trc”后，又恢复正常，现在还没有搞清楚造成这个问题的具体原因是什么？
