Instructions

先決條件：

1.設定 Data Domain 複寫。下列知識庫文章可用於提供指導：

2.指派 ddboost 使用者到複製的 mtree。

ddboost storage-unit modify "MTREE NAME" user "DDBoost User"
取得執行的儲存單元清單： ddboost storage-unit show
取得 DD Boost 使用者執行的清單： ddboost user show

Oracle RMAN 代理程式：

1.Data Domain 及其他對應儲存裝置的註冊密碼箱：

RUN {
ALLOCATE CHANNEL C1 TYPE 'SBT_TAPE' TRACE 5 PARMS 'BLKSIZE=1048576,
SBT_LIBRARY=/home/oracle1/rman_agent_home/lib/libddobk.so,
ENV=(BACKUP_HOST=DD1.lss.emc.com,
RMAN_AGENT_HOME=/home/oracle1/rman_agent_home)';
send 'set username q_ost password 1X3quest servername DD1.lss.emc.com storageunit rman_su1';
send 'set username q_ost password 1X3quest servername DD2.lss.emc.com storageunit rman_su1_dr';
RELEASE CHANNEL C1;
}


2.使用 RMAN 指令檔將資料庫備份至主要 Data Domain 

RUN {
ALLOCATE CHANNEL CH1 TYPE 'SBT_TAPE' TRACE 5 PARMS
'BLKSIZE=1048576,
SBT_LIBRARY=/home/oracle1/rman_agent_home/lib/libddobk.so,
ENV=(STORAGE_UNIT=rman_su1,
BACKUP_HOST=DD1.lss.emc.com,
RMAN_AGENT_HOME=/home/oracle1/rman_agent_home)';
BACKUP DATABASE FORMAT './testdir/%u_%p';
RELEASE CHANNEL CH1;
}


3.從主要 Data Domain 執行資料庫還原。 

RUN {
ALLOCATE CHANNEL C1 TYPE 'SBT_TAPE' TRACE 5 PARMS 'BLKSIZE=1048576,
SBT_LIBRARY=/home/oracle1/rman_agent_home/lib/libddobk.so,
ENV=(STORAGE_UNIT=rman_su1,
BACKUP_HOST=DD1.lss.emc.com,
RMAN_AGENT_HOME=/home/oracle1/rman_agent_home)';
RESTORE DATABASE;
RECOVER DATABASE;
RELEASE CHANNEL CH1;
}


4.從次要 Data Domain 執行資料庫還原。 

RUN {
ALLOCATE CHANNEL C1 TYPE 'SBT_TAPE' TRACE 5 PARMS 'BLKSIZE=1048576,
SBT_LIBRARY=/home/oracle1/rman_agent_home/lib/libddobk.so,
ENV=(STORAGE_UNIT=rman_su1_dr,
BACKUP_HOST=DD2.lss.emc.com,
RMAN_AGENT_HOME=/home/oracle1/rman_agent_home)';
RESTORE DATABASE;
RECOVER DATABASE;
RELEASE CHANNEL CH1;
}

DDBEA

主要 Data Domain 的 CFG configuration_file1

DDBOOST_USER = ddboost
DEVICE_HOST = DD1.lss.emc.com
DEVICE_PATH = /rman_su1
CLIENT = orahost1

次要 Data Domain 的 CFG configuration_file2

DDBOOST_USER = ddboost
DEVICE_HOST = DD2.lss.emc.com
DEVICE_PATH = /rman_su1_dr
CLIENT = orahost1

1.註冊主要 Data Domain 的加密箱。

/opt/dpsapps/dbappagent/bin/ddbmadmin -P -z configuration_file1


2.使用 RMAN 指令檔將資料庫備份至主要 Data Domain 

RUN {
ALLOCATE CHANNEL C1 DEVICE TYPE SBT_TAPE PARMS 'BLKSIZE=1048576, 
SBT_LIBRARY=/opt/dpsapps/dbappagent/lib/lib64/libddboostora.so, 
SBT_PARMS=(CONFIG_FILE=/orasnb/configuration_file1)'
FORMAT '%d_%U';
BACKUP DATABASE;
RELEASE CHANNEL CH1;
}


3.從主要 Data Domain 執行資料庫還原。 

RUN {
ALLOCATE CHANNEL DEVICE TYPE SBT_TAPE PARMS
'SBT_LIBRARY=/opt/dpsapps/dbappagent/lib/lib64/libddboostora.so,
SBT_PARMS=(CONFIG_FILE=/orasnb/configuration_file1)';
RESTORE DATABASE;
RECOVER DATABASE;
RELEASE CHANNEL CH1;
}


4.從次要 Data Domain 執行資料庫還原。

i） 為次要 Data Domain 註冊加密箱：
/opt/dpsapps/dbappagent/bin/ddbmadmin -P -z configuration_file2

ii） 執行資料庫復原： 
RUN {
ALLOCATE CHANNEL C1 DEVICE TYPE SBT_TAPE PARMS 'BLKSIZE=1048576, 
SBT_LIBRARY=/opt/dpsapps/dbappagent/lib/lib64/libddboostora.so, 
SBT_PARMS=(CONFIG_FILE=/orasnb/configuration_file2)';
RESTORE DATABASE;
RECOVER DATABASE;
RELEASE CHANNEL CH1;
}
