之前从未测试过ogg抽取Physical standby或ADG的情况，今天测试了一下，由于最近一个项目是9208的升级，需要利用OGG。因此下午利用一个vm搭建了DG顺便测试了OGG，如下是简单的步骤，供参考！
1. 主库
[ora9@killdb killdb]$ sqlplus "/as sysdba" SQL*Plus: Release 9.2.0.8.0 - Production on Mon Dec 8 22:44:32 2014 Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved.

2. 备份主库以及控制文件
[ora9@killdb killdb]$ rman target / Recovery Manager: Release 9.2.0.8.0 - Production Copyright (c) 1995, 2002, Oracle Corporation. All rights reserved. connected to target database: KILLDB (DBID=801221485) RMAN> backup database format='/home/ora9/killdb_full.bak'; Starting backup at 08-DEC-14 using target database controlfile instead of recovery catalog allocated channel: ORA_DISK_1 channel ORA_DISK_1: sid=17 devtype=DISK channel ORA_DISK_1: starting full datafile backupset channel ORA_DISK_1: specifying datafile(s) in backupset including current SPFILE in backupset including current controlfile in backupset input datafile fno=00001 name=/home/ora9/oradata/killdb/system01.dbf input datafile fno=00011 name=/home/ora9/oradata/killdb/jwdb01.dbf input datafile fno=00002 name=/home/ora9/oradata/killdb/undotbs01.dbf input datafile fno=00004 name=/home/ora9/oradata/killdb/example01.dbf input datafile fno=00009 name=/home/ora9/oradata/killdb/xdb01.dbf input datafile fno=00005 name=/home/ora9/oradata/killdb/indx01.dbf input datafile fno=00006 name=/home/ora9/oradata/killdb/odm01.dbf input datafile fno=00008 name=/home/ora9/oradata/killdb/users01.dbf input datafile fno=00003 name=/home/ora9/oradata/killdb/drsys01.dbf input datafile fno=00010 name=/home/ora9/oradata/killdb/cwmlite01.dbf input datafile fno=00007 name=/home/ora9/oradata/killdb/tools01.dbf channel ORA_DISK_1: starting piece 1 at 08-DEC-14 channel ORA_DISK_1: finished piece 1 at 08-DEC-14 piece handle=/home/ora9/killdb_full.bak comment=NONE channel ORA_DISK_1: backup set complete, elapsed time: 00:01:06 Finished backup at 08-DEC-14 RMAN> backup current controlfile ; Starting backup at 08-DEC-14 using target database controlfile instead of recovery catalog allocated channel: ORA_DISK_1 channel ORA_DISK_1: sid=12 devtype=DISK channel ORA_DISK_1: starting full datafile backupset channel ORA_DISK_1: specifying datafile(s) in backupset including current controlfile in backupset channel ORA_DISK_1: starting piece 1 at 08-DEC-14 channel ORA_DISK_1: finished piece 1 at 08-DEC-14 piece handle=/home/ora9/product/9.2/dbs/03ppmf95_1_1 comment=NONE channel ORA_DISK_1: backup set complete, elapsed time: 00:00:01 Finished backup at 08-DEC-14
3. 准备备库pfile并启动备库实例
--create pfile SQL> create pfile='/tmp/pfile.ora' from spfile; File created. --修改pfile *.aq_tm_processes=1 *.background_dump_dest='/home/ora9/admin/std9/bdump' *.compatible='9.2.0.0.0' *.control_files='/home/ora9/oradata/std9/control01.ctl','/home/ora9/oradata/std9/control02.ctl','/home/ora9/oradata/std9/control03.ctl' *.core_dump_dest='/home/ora9/admin/std9/cdump' *.db_block_size=4096 *.db_cache_size=50000000 *.db_domain='' *.db_file_multiblock_read_count=8 *.db_name='killdb' *.dispatchers='(PROTOCOL=TCP) (SERVICE=killdbXDB)' *.fast_start_mttr_target=300 *.hash_join_enabled=FALSE *.instance_name='std9' *.java_pool_size=83886080 *.job_queue_processes=10 *.large_pool_size=16777216 *.log_archive_dest_1='location=/home/ora9/arch_s' *.log_archive_start=TRUE *.open_cursors=300 *.pga_aggregate_target=16777216 *.processes=150 *.query_rewrite_enabled='FALSE' *.remote_login_passwordfile='EXCLUSIVE' *.sga_max_size=100000000 *.shared_pool_size=83886080 *.sort_area_size=524288 *.star_transformation_enabled='FALSE' *.timed_statistics=TRUE *.undo_management='AUTO' *.undo_retention=900 *.undo_tablespace='UNDOTBS1' *.user_dump_dest='/home/ora9/admin/std9/udump'
说明：将其中的killdb全部修改为std9
另外创建相关的目录.步骤略.

4. 备库restore数据文件

5. 停止备库
SQL> shutdown abort; ORACLE instance shut down. SQL> startup nomount ORACLE instance started. Total System Global Area 252776884 bytes Fixed Size 450996 bytes Variable Size 201326592 bytes Database Buffers 50331648 bytes Redo Buffers 667648 bytes
6. 主库创建standby controlfile
SQL> alter database create standby controlfile as '/tmp/std9.ctl'; Database altered.
7. 替换备库的控制文件
cp /tmp/std9.ctl /home/ora9/oradata/std9/control01.ctl cp /tmp/std9.ctl /home/ora9/oradata/std9/control02.ctl cp /tmp/std9.ctl /home/ora9/oradata/std9/control03.ctl
说明，由于我是在同一个VM进行操作，因此这里我直接cp覆盖即可.
8. 启动备库
SQL> startup nomount ORACLE instance started. Total System Global Area 252776884 bytes Fixed Size 450996 bytes Variable Size 201326592 bytes Database Buffers 50331648 bytes Redo Buffers 667648 bytes SQL> alter database mount standby database; Database altered.
9. 修改tsnames.ora,listener.ora
--tnsnames.ora KILLDB = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521)) ) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = killdb) ) ) std9 = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521)) ) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = std9) ) ) ---listener.ora SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = PLSExtProc) (ORACLE_HOME = /home/ora9/product/9.2/) (PROGRAM = extproc) ) (SID_DESC = (GLOBAL_DBNAME = jw) (ORACLE_HOME = /home/ora9/product/9.2) (SID_NAME = jw) ) (SID_DESC = (GLOBAL_DBNAME = killdb) (ORACLE_HOME = /home/ora9/product/9.2) (SID_NAME = killdb) ) (SID_DESC = (GLOBAL_DBNAME = std9) (ORACLE_HOME = /home/ora9/product/9.2) (SID_NAME = std9) ) )
注意，这里最好是使用静态注册.
10. rename备库数据文件
由于替换了备库的控制文件，因此我们需要rename 数据文件，否则启动dg的recover会报错。
SQL> alter system set standby_file_management=manual; System altered. SQL> alter database rename file '/home/ora9/oradata/killdb/system01.dbf' to '/home/ora9/oradata/std9/system01.dbf' ; Database altered. SQL> alter database rename file '/home/ora9/oradata/killdb/undotbs01.dbf' to '/home/ora9/oradata/std9/undotbs01.dbf'; Database altered.

SQL> select name from v$controlfile; NAME -------------------------------------------------------------------------------- /home/ora9/oradata/std9/control01.ctl /home/ora9/oradata/std9/control02.ctl /home/ora9/oradata/std9/control03.ctl SQL> select name from v$datafile; NAME -------------------------------------------------------------------------------- /home/ora9/oradata/std9/system01.dbf /home/ora9/oradata/std9/undotbs01.dbf /home/ora9/oradata/std9/drsys01.dbf /home/ora9/oradata/std9/example01.dbf /home/ora9/oradata/std9/indx01.dbf /home/ora9/oradata/std9/odm01.dbf /home/ora9/oradata/std9/tools01.dbf /home/ora9/oradata/std9/users01.dbf /home/ora9/oradata/std9/xdb01.dbf /home/ora9/oradata/std9/cwmlite01.dbf /home/ora9/oradata/std9/jwdb01.dbf 11 rows selected. SQL> select name from v$tempfile; no rows selected SQL> alter system set standby_file_management=auto; System altered.
12. 修改gap获取参数(备库操作)
SQL> alter system set FAL_SERVER='killdb'; System altered. SQL> alter system set FAL_CLIENT='std9'; System altered.
13. 启动备库的同步
SQL> alter database recover managed standby database disconnect from session; Database altered.
上述为9208 版本的physical standby手工搭建过程，如下是诊断standby 进程ogg同步的配置。
1. 配置源端mgr

2. 配置源端抽取进程

3. 配置源端pump进程
GGSCI (killdb.com) 16> edit param dp1 EXTRACT dp1 RMTHOST 192.168.109.12, MGRPORT 7809 TCPBUFSIZE 5000000 PASSTHRU RMTTRAIL ./dirdat/r1 NUMFILES 3000 TABLE roger.*; ~ ~ ~ "dirprm/dp1.prm" [New] 7L, 129C written GGSCI (killdb.com) 17> add extract dp1, exttrailsource ./dirdat/ra EXTRACT added.

4. 启动源端进程
5. 配置目标端replicat进程
GGSCI (killdb.com) 13> view param rep6 replicat rep6 userid ggs@Roger,password AADAAAAAAAAAAADAKHEJYIFGVAKDPFZBGDFJNEQBBJRISJAAOCHHZEWCEFTCRIRCJDSHUHAJZBFDZEWC,encryptkey kasaur_key reperror default, discard discardfile ./dirrpt/rep6.dsc, append, megabytes 50 assumetargetdefs allownoopupdates numfiles 3000 map roger.t_buffer, target roger.t_buffer; GGSCI (killdb.com) 5> add replicat rep6, exttrail ./dirdat/r1 REPLICAT added.
