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@rh6 dbs]$ rman target / catalog rman/rman@orcl
Recovery Manager: Release 11.2.0.1.0 - Production on Tue Apr 7 11:29:41 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@rh6 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 ch1 device type disk;
6> delete noprompt obsolete recovery window of 15 days;
7> release channel ch1;
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？
