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

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> }

告警日志:

[oracle@rh7 ~]$ tail -f /u01/app/oracle/diag/rdbms/prod/prod/trace/alert_prod.log
Tue Apr 07 11:27:16 2015

Tue Apr 07 11:27:19 2015

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?
