关于10g RAC监听设置，tnsnames.ora设置，VIP及客户端配置问题

按照文档安装完成，但是lsnrctl status 没有发现节点2

gnd-rac01</etc>$lsnrctl status

监听默认设置：（这里的10.155.4.95是另外一个public nic , 在安装crs的时候do not use ）

gnd-rac01</u01/product/oracle/network/admin>$cat listener.ora
# listener.ora.gnd-rac01 Network Configuration File: /u01/product/oracle/network/admin/listener.ora.gnd-rac01
# Generated by Oracle configuration tools.

LISTENER_GND-RAC01 =

(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = gnd-vip01)(PORT = 1521)(IP = FIRST))
)
(ADDRESS_LIST =

)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
)
)
)

---------------------------------------------------------------------------------------------------------------

tnsnames.ora 设置：

gnd-rac01</u01/product/oracle/network/admin>$cat tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/product/oracle/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

TPC2 =

(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = tpc)
(INSTANCE_NAME = tpc2)
)
)

TPC1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = gnd-vip01)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = tpc)
(INSTANCE_NAME = tpc1)
)
)

TPC =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = gnd-vip01)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = gnd-vip02)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = tpc)
)
)

LISTENERS_TPC =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = gnd-vip01)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = gnd-vip02)(PORT = 1521))
)

--------------------------------------------------------------------------------------------------------------------------------

这样的默认设置需要如何更改？

在DBCA的时候没有配置TAF , 客户端如何设置连接？

目前用单机连接方式 (ADDRESS = (PROTOCOL = TCP)(HOST = 10.155.4.95)(PORT = 1521)(IP = FIRST)) 可以，配置如下：

GND-RAC1 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.155.4.95)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = tpc)
(INSTANCE_NAME = tpc1)
)
)

只有 10.155.4.95 能连接，其他ip配置都不能连接

-----------------

RAC 客户端程序设置tnsnames.ora

TPC_RAC =
(DESCRIPTION =
(FAILOVER=ON)
(LOAD_BALANCE = ON)
(ADDRESS = (PROTOCOL = TCP)(HOST = gnd-vip01)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = gnd-vip02)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = TPC)
(FAILOVER_MODE=(TYPE=SELECT)(METHOD=BASIC))
)
)

其中VIP名称更改为虚拟IP也可以 .
