下面测试来至一次增加与删除实例实验，在10G RAC中知道监听是通过netca来管理的，跟11G的机制不一样。
当增加节点的时候，需要手动执行netca来注册监听服务。其实我们也可以通过crs_profile工具来手动注册监听服务。

1，配置tnsnames.ora与listener.ora文件
如下：
| [root@www.htz.pw admin] $ cat listener.ora # listener.ora.sol1 Network Configuration File: /oracle/app/oracle/product/10.2.0/db_1/network/admin/listener.ora.sol1 # Generated by Oracle configuration tools.
LISTENER_SOL1 = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.111.48)(PORT = 1521)(IP = FIRST)) (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.111.46)(PORT = 1521)(IP = FIRST)) ) ) #这里建议使用IP地址 SID_LIST_LISTENER_SOL1 = (SID_LIST = (SID_DESC = (SID_NAME = PLSExtProc) (ORACLE_HOME = /oracle/app/oracle/product/10.2.0/db_1) (PROGRAM = extproc) ) )
[root@www.htz.pw app] $cd $ORACLE_HOME/network/admin [root@www.htz.pw admin] $ cat tnsnames.ora # tnsnames.ora.sol1 Network Configuration File: /oracle/app/oracle/product/10.2.0/db_1/network/admin/tnsnames.ora.sol1 # Generated by Oracle configuration tools.
LISTENERS_SOL10G = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = sol1-vip)(PORT = 1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = sol2-vip)(PORT = 1521)) ) #这里建议使用IP地址，在10G中配置REMOTE_LISTENER的时候，默认会用到这里的东西 SOL10G2 = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = sol2-vip)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = sol10g) (INSTANCE_NAME = sol10g2) ) )
SOL10G1 = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = sol1-vip)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = sol10g) (INSTANCE_NAME = sol10g1) ) )
SOL10G = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = sol1-vip)(PORT = 1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = sol2-vip)(PORT = 1521)) (LOAD_BALANCE = yes) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = sol10g) ) ) |
2，crs_register注册监听服务
注意监听服务有两种方法，1，利用现在的监听的配置信息。2，使用crs_profile来创建
2.1 利用现有的监听配置信息
| [oracle@www.htz.pw oracle] $ crs_stat -p ora.sol2.LISTENER_SOL2.lsnr >/tmp/listener.txt 这里导出正常节点的监听配置信息
[oracle@www.htz.pw oracle] $ cat /tmp/listener.txt NAME=ora.sol1.LISTENER_SOL1.lsnr #这里需要注意的LISTENER_SOL1这个名字需要跟listener.ora中的监听名一致 TYPE=application ACTION_SCRIPT=/oracle/app/oracle/product/10.2.0/db_1/bin/racgwrap ACTIVE_PLACEMENT=0 AUTO_START=1 CHECK_INTERVAL=600 DESCRIPTION=CRS application for listener on node FAILOVER_DELAY=0 FAILURE_INTERVAL=0 FAILURE_THRESHOLD=0 HOSTING_MEMBERS=sol1 OPTIONAL_RESOURCES= PLACEMENT=restricted REQUIRED_RESOURCES=ora.sol1.vip RESTART_ATTEMPTS=5 SCRIPT_TIMEOUT=600 START_TIMEOUT=0 STOP_TIMEOUT=0 UPTIME_THRESHOLD=7d USR_ORA_ALERT_NAME= USR_ORA_CHECK_TIMEOUT=0 USR_ORA_CONNECT_STR=/ as sysdba USR_ORA_DEBUG=0 USR_ORA_DISCONNECT=false USR_ORA_FLAGS= USR_ORA_IF= USR_ORA_INST_NOT_SHUTDOWN= USR_ORA_LANG= USR_ORA_NETMASK= USR_ORA_OPEN_MODE= USR_ORA_OPI=false USR_ORA_PFILE= USR_ORA_PRECONNECT=none USR_ORA_SRV= USR_ORA_START_TIMEOUT=0 USR_ORA_STOP_MODE=immediate USR_ORA_STOP_TIMEOUT=0 USR_ORA_VIP= 一共就3个地址需要修改 [oracle@www.htz.pw oracle]$ mv /tmp/listener.txt $ORA_CRS_HOME/crs/public/ora.sol1.LISTENER_SOL1.lsnr.cap [oracle@www.htz.pw oracle]$ crs_register ora.sol1.LISTENER_SOL1.lsnr [oracle@www.htz.pw oracle]$ crs_start ora.sol1.LISTENER_SOL1.lsnr Attempting to start `ora.sol1.LISTENER_SOL1.lsnr` on member `sol1` Start of `ora.sol1.LISTENER_SOL1.lsnr` on member `sol1` succeeded. 监听能正常启动 |
2.2 使用crs_profiler来手动创建监听
不到万不得以，不建议使用下面的方法
| [oracle@www.htz.pw oracle]$ crs_profile -create ora.sol1.LISTENER_SOL1.lsnr -t application -a /oracle/app/oracle/product/10.2.0/db_1/bin/racgwrap -d "CRS application for listener on node" -h sol1 -r ora.sol1.vip -p restricted -o as=1,ci=600,st=600,ra=5
[oracle@www.htz.pw oracle]$ cat ora.sol1.LISTENER_SOL1.lsnr.cap NAME=ora.sol1.LISTENER_SOL1.lsnr TYPE=application ACTION_SCRIPT=/oracle/app/oracle/product/10.2.0/db_1/bin/racgwrap ACTIVE_PLACEMENT=0 AUTO_START=1 CHECK_INTERVAL=600 DESCRIPTION=CRS application for listener on node FAILOVER_DELAY=0 FAILURE_INTERVAL=0 FAILURE_THRESHOLD=0 HOSTING_MEMBERS=sol1 OPTIONAL_RESOURCES= PLACEMENT=restricted REQUIRED_RESOURCES=ora.sol1.vip RESTART_ATTEMPTS=5 SCRIPT_TIMEOUT=600 START_TIMEOUT=0 STOP_TIMEOUT=0 UPTIME_THRESHOLD=7d USR_ORA_ALERT_NAME= USR_ORA_CHECK_TIMEOUT=0 USR_ORA_CONNECT_STR=/ as sysdba USR_ORA_DEBUG=0 USR_ORA_DISCONNECT=false USR_ORA_FLAGS= USR_ORA_IF= USR_ORA_INST_NOT_SHUTDOWN= USR_ORA_LANG= USR_ORA_NETMASK= USR_ORA_OPEN_MODE= USR_ORA_OPI=false USR_ORA_PFILE= USR_ORA_PRECONNECT=none USR_ORA_SRV= USR_ORA_START_TIMEOUT=0 USR_ORA_STOP_MODE=immediate USR_ORA_STOP_TIMEOUT=0 USR_ORA_VIP=
[oracle@www.htz.pw oracle]$ crs_register ora.sol1.LISTENER_SOL1.lsnr [oracle@www.htz.pw oracle]$ crs_start ora.sol1.LISTENER_SOL1.lsnr Attempting to start `ora.sol1.LISTENER_SOL1.lsnr` on member `sol1` Start of `ora.sol1.LISTENER_SOL1.lsnr` on member `sol1` succeeded
其实如果是VIP资源的时候，我们需要注意了，因为VIP资料的属组是root [oracle@www.htz.pw oracle]$ crs_stat -ls Name Owner Primary PrivGrp Permission ----------------------------------------------------------------- ora....L1.lsnr oracle oinstall rwxrwxr-- ora.sol1.gsd oracle oinstall rwxr-xr-- ora.sol1.ons oracle oinstall rwxr-xr-- ora.sol1.vip root oinstall rwxr-xr-- ora.sol10g.db oracle oinstall rwxrwxr-- ora....g2.inst oracle oinstall rwxrwxr-- ora....SM2.asm oracle oinstall rwxrwxr-- ora....L2.lsnr oracle oinstall rwxrwxr-- ora.sol2.gsd oracle oinstall rwxr-xr-- ora.sol2.ons oracle oinstall rwxr-xr-- ora.sol2.vip root oinstall rwxr-xr |
