在Oracle中，如何将一个数据库添加到CRS中？
答案部分
虽然通过DBCA（DataBase Configuration Assistant，数据库配置助手）创建的数据库会自动加入CRS中，但通过RMAN创建的数据库是不会被加入CRS中的，在这种情况下就需要手动添加，将数据库加入CRS中后就可以通过srvctl来管理数据库了。
主要的命令包括：
srvctl remove database -d lhrrac1 -f
srvctl add db -d lhrrac1 -o /u01/app/oracle/product/11.2.0/dbhome_1 -c RAC -p '+DATA/lhrrac1/spfilelhrrac1.ora' -r PRIMARY
srvctl add instance -d lhrrac1 -i lhrrac11 -n raclhr-11gR2-N1
srvctl add instance -d lhrrac1 -i lhrrac12 -n raclhr-11gR2-N2
crsctl start res ora.lhrrac1.db
srvctl config db -d lhrrac1 -a
crsctl stat res ora.lhrrac1.db -p
修改数据库的属性：
srvctl modify database -d lhrrac1 -p '+DATA/lhrrac1/spfilelhrrac.ora'
srvctl modify database -d lhrrac1 -s MOUNT
srvctl modify database -d lhrrac1 -t ABORT
srvctl modify database -d lhrrac1 -s open -t immediate
禁用数据库随CRS的启动而启动：
crsctl modify resource ora.lhrrac1.db -attr AUTO_START=never
crsctl stat res ora.lhrrac1.db -p | grep AUTO_START
禁止CRS管理数据库：
srvctl disable db -d lhrrac1
crsctl stat res ora.lhrrac1.db -p | grep ENABLE
crsctl modify res ora.lhrrac1.db -attr "ENABLED=0"
属性AUTO_START表示Oracle Clusterware在群集服务器重启后是否自动启动资源。有效的AUTO_START值为：
l always：在服务器重新启动时重新启动资源，而不管服务器停止时资源的状态如何。
l restore：将资源恢复到服务器停止时的状态。如果在服务器停止之前TARGET的值为ONLINE，那么Oracle Clusterware会尝试重新启动资源。
l never：无论服务器何时停止，Oracle Clusterware都不会重新启动资源。
下面的例子演示了如何将一个物理DG添加到CRS中。

[ZHLHRDB2:oracle]:/oracle>srvctl add database -h
Adds a database configuration to the Oracle Clusterware.
Usage: srvctl add database -d <db_unique_name> -o <oracle_home> [-c {RACONENODE | RAC | SINGLE} [-e <server_list>] [-i <inst_name>] [-w <timeout>]] [-m <domain_name>] [-p <spfile>] [-r {PRIMARY | PHYSICAL_STANDBY | LOGICAL_STANDBY | SNAPSHOT_STANDBY}] [-s <start_options>] [-t <stop_options>] [-n <db_name>] [-y {AUTOMATIC | MANUAL | NORESTART}] [-g "<serverpool_list>"] [-x <node_name>] [-a "<diskgroup_list>"] [-j "<acfs_path_list>"]
-d <db_unique_name> Unique name for the database
-o <oracle_home> ORACLE_HOME path
-c <type> Type of database: RAC One Node, RAC, or Single Instance
-e <server_list> Candidate server list for RAC One Node database
-i <inst_name> Instance name prefix for administrator-managed RAC One Node database (default first 12 characters of <db_unique_name>)
-w <timeout> Online relocation timeout in minutes
-x <node_name> Node name. -x option is specified for single-instance databases
-m <domain> Domain for database. Must be set if database has DB_DOMAIN set.
-p <spfile> Server parameter file path

-t <stop_options> Stop options for the database. Examples of shutdown options are NORMAL, TRANSACTIONAL, IMMEDIATE, or ABORT.
-n <db_name> Database name (DB_NAME), if different from the unique name given by the -d option
-y <dbpolicy> Management policy for the database (AUTOMATIC, MANUAL, or NORESTART)
-g "<serverpool_list>" Comma separated list of database server pool names
-a "<diskgroup_list>" Comma separated list of disk groups
-j "<acfs_path_list>" Comma separated list of ACFS paths where database's dependency will be set
