测试环境:
1.1更改为强制日志切换
在DataGuard环境中,为了减少故障时数据损失,我们可以设置ARCHIVE_LAG_TARGET参数,强制进行日志切换。
SYS@ocp> selectlog_mode,force_logging from v$database;
LOG_MODE FOR
------------ ---
ARCHIVELOG NO
SYS@ocp> ALTERDATABASE FORCE LOGGING;
Database altered.
SYS@ocp> selectlog_mode,force_logging from v$database;
LOG_MODE FOR
------------ ---
ARCHIVELOG YES
1.2 创建备库日志文件
首先查询主库的
SYS@ocp> selectgroup#,bytes/1024/1024 from v$log;
GROUP# BYTES/1024/1024
-------------------------
1 50
2 50
3 50
SYS@ocp> selectmember from v$logfile;
MEMBER
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
/database/ocp/redo03.log
/database/ocp/redo02.log
/database/ocp/redo01.log
创建standby日志组的个数是原日志组个数+1再与thread的积，size不能小于原日志文件的大小。
alter database addstandby logfile '/database/ocp/standby01.log' size 50m;
alter database addstandby logfile '/database/ocp/standby02.log' size 50m;
alter database addstandby logfile '/database/ocp/standby03.log' size 50m;
alter database addstandby logfile '/database/ocp/standby04.log' size 50m;
具体步骤：
SYS@ocp> alterdatabase add standby logfile '/database/ocp/standby01.log' size 50m;
Database altered.
SYS@ocp> alterdatabase add standby logfile '/database/ocp/standby02.log' size 50m;
Database altered.
SYS@ocp> alterdatabase add standby logfile '/database/ocp/standby03.log' size 50m;
Database altered.
SYS@ocp> alterdatabase add standby logfile '/database/ocp/standby04.log' size 50m;
Database altered.
SYS@ocp> selectmember from v$logfile;
MEMBER
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
/database/ocp/redo03.log
/database/ocp/redo02.log
/database/ocp/redo01.log
/database/ocp/standby01.log
/database/ocp/standby02.log
/database/ocp/standby03.log
/database/ocp/standby04.log
7 rows selected.
1.3 确认已经开启数据库闪回
SYS@ocp> selectlog_mode,open_mode,flashback_on from v$database;
LOG_MODE OPEN_MODE FLASHBACK_ON
-------------------------------- ------------------
ARCHIVELOG READ WRITE NO
1.4修改参数文件
SYS@ocp>alter system set log_archive_config='DG_CONFIG=(ocp,oca)';
System altered.
SYS@ocp>altersystem set log_archive_dest_2='SERVICE=ocaVALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=oca' scope=spfile;
SYS@ocp> altersystem set log_archive_dest_state_1='enable';
System altered.
SYS@ocp> altersystem set log_archive_dest_state_2='enable';
System altered.
SYS@ocp>altersystem set db_file_name_convert='/database/ocp','/database/ocp' scope=spfile;
System altered.
SYS@ocp> altersystem set log_file_name_convert='/database/ocp','/database/ocp'scope=spfile;
System altered.
SYS@ocp>alter system set fal_server='ocp';
System altered.
SYS@ocp>alter system set fal_client='oca';
System altered.
SYS@ocp> altersystem set standby_file_management='AUTO';
System altered.
由于上述生效需要重启，所以重启数据库
SYS@ocp> shutdownimmediate
Database closed.
Database dismounted.
ORACLE instance shutdown.
SYS@ocp>
SYS@ocp>
SYS@ocp> startup
ORACLE instancestarted.

1.1更改为强制日志切换
在DataGuard环境中,为了减少故障时数据损失,我们可以设置ARCHIVE_LAG_TARGET参数,强制进行日志切换。
SYS@ocp> selectlog_mode,force_logging from v$database;

ARCHIVELOG NO
SYS@ocp> ALTERDATABASE FORCE LOGGING;

SYS@ocp> selectlog_mode,force_logging from v$database;
LOG_MODE FOR
------------ ---
ARCHIVELOG YES
1.2 创建备库日志文件
首先查询主库的
SYS@ocp> selectgroup#,bytes/1024/1024 from v$log;
GROUP# BYTES/1024/1024
-------------------------
1 50
2 50
3 50
SYS@ocp> selectmember from v$logfile;
MEMBER
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
/database/ocp/redo03.log
/database/ocp/redo02.log
/database/ocp/redo01.log
创建standby日志组的个数是原日志组个数+1再与thread的积，size不能小于原日志文件的大小。
alter database addstandby logfile '/database/ocp/standby01.log' size 50m;
alter database addstandby logfile '/database/ocp/standby02.log' size 50m;
alter database addstandby logfile '/database/ocp/standby03.log' size 50m;
alter database addstandby logfile '/database/ocp/standby04.log' size 50m;
具体步骤：
SYS@ocp> alterdatabase add standby logfile '/database/ocp/standby01.log' size 50m;
Database altered.
SYS@ocp> alterdatabase add standby logfile '/database/ocp/standby02.log' size 50m;
Database altered.
SYS@ocp> alterdatabase add standby logfile '/database/ocp/standby03.log' size 50m;
Database altered.
SYS@ocp> alterdatabase add standby logfile '/database/ocp/standby04.log' size 50m;
Database altered.
SYS@ocp> selectmember from v$logfile;
MEMBER
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
/database/ocp/redo03.log
/database/ocp/redo02.log
/database/ocp/redo01.log
/database/ocp/standby01.log
/database/ocp/standby02.log
/database/ocp/standby03.log
/database/ocp/standby04.log
7 rows selected.
1.3 确认已经开启数据库闪回
SYS@ocp> selectlog_mode,open_mode,flashback_on from v$database;
LOG_MODE OPEN_MODE FLASHBACK_ON
-------------------------------- ------------------
ARCHIVELOG READ WRITE NO
1.4修改参数文件
SYS@ocp>alter system set log_archive_config='DG_CONFIG=(ocp,oca)';
System altered.
SYS@ocp>altersystem set log_archive_dest_2='SERVICE=ocaVALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=oca' scope=spfile;
SYS@ocp> altersystem set log_archive_dest_state_1='enable';

SYS@ocp> altersystem set log_archive_dest_state_2='enable';
System altered.
SYS@ocp>altersystem set db_file_name_convert='/database/ocp','/database/ocp' scope=spfile;

System altered.
SYS@ocp>alter system set fal_client='oca';
System altered.
SYS@ocp> altersystem set standby_file_management='AUTO';
