Oracle 9I Data Guard配置

Posted on by

1、修改参数文件
primary:
*.standby_archive_dest=’/opt/ora9/oradata/txzldb/stdarch/’
*.log_archive_dest_2=’service=txzldb.Standby optional reopen=60′ –配置tns
*.utl_file_dir=’/opt/ora9′
*.remote_archive_enable=TRUE
*.standby_file_management=AUTO
*.fal_server=’txzldb.Standby’
*.fal_client=’txzldb.Primary’
*.log_archive_dest_state_2=defer

standby:
*.standby_archive_dest=’/opt/ora9/oradata/txzldb/stdarch/’
*.log_archive_dest_2=’service=txzldb.Primary optional reopen=60′ –配置tns
*.utl_file_dir=’/opt/ora9′
*.remote_archive_enable=TRUE
*.standby_file_management=AUTO
*.fal_server=’txzldb.Primary’
*.fal_client=’txzldb.Standby’
*.log_archive_dest_state_2=defer

2、备份主库
backup database format=’/home/oracle/full_backup_%U_%s.bak’;
sql “alter system archive log current”;
–backup filesperset 10 archivelog all format=’/home/oracle/archivlog_%U_%s.bak’;（可选）
alter database create standby controlfile as ‘/home/oracle/control01.ctl’;

3、拷贝密码文件控制文件
scp /opt/oracle/product/9.2.0/dbs/orapwora9i
192.168.3.2:/opt/oracle/product/9.2.0/dbs/
scp control01.ctl
192.168.3.2:/opt/oracle/oradata/ora9i/control01.ctl

4、恢复备机
拷贝备份至备机与主机相同的目录
sqlplus “/ as sysdba”
　　startup nomount pfile=”
　　alter database mount standby database;
　　exit
　　rman target / nocatalog
　　restore database
–restore archivelog all;（可选）
–recover automatic standby database;（可选）

5、启动恢复状态
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;
create spfile from pfile=”;
alter system set log_archive_dest_state_2=enable scope=both;

6、添加临时表空间
recover managed standby database cancel;
alter database open read only;
alter tablespace temp add tempfile ‘/opt/oracle/oradata/ora9i/temp01.dbf’
SIZE 412M AUTOEXTEND ON NEXT 640K MAXSIZE UNLIMITED;
shutdown immediate;
startup nomount pfile=”
alter database mount standby database;
recover managed standby database disconnect from session;

Oracle 调度程序作业–修改执行时间

Posted on by 
--DBMS_SCHEDULER 运行信息
select job_name,state,enabled,to_char(last_start_date,'yyyy-mm-dd hh24:mi:ss'), schedule_name 
from dba_scheduler_jobs; 

--DBMS_SCHEDULER运行成功与否信息
SELECT log_id, job_name, status,TO_CHAR(ACTUAL_START_DATE,'yyyy-mm-dd HH24:MI:ss') start_date,
           TO_CHAR (log_date, 'yyyy-mm-dd HH24:MI:ss') log_date
      FROM dba_scheduler_job_run_details 
     WHERE job_name = 'GATHER_STATS_JOB' 
     order by 4 DESC;
      
--查询执行时间情况
select t1.window_name,t1.repeat_interval,t1.duration from dba_scheduler_windows t1,dba_scheduler_wingroup_members t2 
 where t1.window_name=t2.window_name and t2.window_group_name='MAINTENANCE_WINDOW_GROUP'; 
 
--修改执行时间
begin 
dbms_scheduler.set_attribute('WEEKEND_WINDOW','REPEAT_INTERVAL','freq=daily;byday=SAT;byhour=0;byminute=0;bysecond=0'); 
dbms_scheduler.set_attribute('WEEKEND_WINDOW','DURATION','+002 00:00:00'); 
end;

ORA-01410: invalid ROWID 分析

Posted on by

1、跟踪错误表
alter session set max_dump_file_size=unlimited;
alter session set db_file_multiblock_read_count=1;
alter session set events ‘10200 trace name context forever, level 1’;
执行下面语句
SELECT COUNT(*) FROM QXTDEV1.TAB_SMS_MT_DOWN
报错
ORA-01410: invalid ROWID
alter session set events ‘10200 trace name context off’;

2、查看跟踪文件尾部
Consistent read started for block 0 : 00400652
env: (scn: 0x0abf.1ee04657 xid: 0x0000.000.00000000 uba: 0x00000000.0000.00 statement num=0 parent xid: xid: 0x0000.000.00000000 scn: 0x0000.00000000 0sch: scn: 0x0000.00000000)
Consistent read finished for block 0 : 400652
Consistent read finished for block 0 : 400652
通过这个文件看到文件读到400652的块的时候终止了，错误应该在这块上

3、分析400652块内容
–转换为10进制
SELECT to_number(‘400652′,’xxxxxxxx’) FROM dual;
–求文件号和块号
SELECT DBMS_UTILITY.DATA_BLOCK_ADDRESS_FILE(4195922),
DBMS_UTILITY.DATA_BLOCK_ADDRESS_BLOCK(4195922)
FROM DUAL;

4、dump文件号为1，块号为1618的内容
alter system dump datafile 1 block 1618;
Block header dump: 0x00400652
Object id on Block? Y
seg/obj: 0xde csc: 0xabf.1e400c0c itc: 2 flg: O typ: 1 – DATA
fsl: 0 fnx: 0x0 ver: 0x01
得到object_id为de，转化为十进制
SELECT to_number(‘de’,’xx’) FROM dual;
查询all_objects表
SELECT * FROM All_Objects WHERE object_id=222;
发现这个数据库（绝对块号400652，相对：文件号1，块号1618）指向的表为dual

5、得出结论
我们的QXTDEV1.TAB_SMS_MT_DOWN表中的数据块指向了sys.dual表，从而出现了ORA-01410错误

undo损坏恢复–有事务

Posted on by

startup nomount;
create pfile=’/tmp/pfile’ from spfile;

修改pfile
*._allow_resetlogs_corruption=true
*._corrupted_rollback_segments=(_SYSSMU1$,_SYSSMU2$,_SYSSMU3$,_SYSSMU4$,
_SYSSMU5$,_SYSSMU6$,_SYSSMU7$,_SYSSMU8$,_SYSSMU9$,_SYSSMU10$)

startup pfile=’/tmp/pfile’ mount;
–undo数据文件不用离线也可以打开的时候（2），不行采用下面的方法
alter database datafile 2 offline drop;
alter database open;

CREATE UNDO TABLESPACE UNDOTBS01
DATAFILE ‘/opt/oracle/oradata/xifenfei/UNDOTBS01.dbf’ SIZE 50M;
select segment_name,status from dba_rollback_segs;–查看是否有回滚段被创建，处于offline状态
shutdown immediate;

修改pfile：
*.undo_tablespace=’UNDOTBS01′

startup pfile=’/tmp/pfile’
–alter tablespace undotbs1 offline normal;（2）–使数据文件先离线，如果开始已经离线，这里不需要处理
select segment_name,status from dba_rollback_segs;
drop rollback segment “_SYSSMUx$”;
drop tablespace UNDOTBS02 including contents and datafiles;
select * from v$recover_file;–验证是否还有文件需要恢复
shutdown immediate

修改参数文件
#*._allow_resetlogs_corruption=true
#*._corrupted_rollback_segments=(_SYSSMU1$,_SYSSMU2$,_SYSSMU3$,_SYSSMU4$,_SYSSMU5$,
_SYSSMU6$,_SYSSMU7$,_SYSSMU8$,_SYSSMU9$,_SYSSMU10$)

startup pfile=’/tmp/pfile’;
create spfile from pfile=’/tmp/pfile’;
