篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了测试客户端连接12c ASM实例相关的知识，希望对你有一定的参考价值。
环境：Oracle 12.2.0.1 RAC
背景：用户反映12c ASM创建的用户具备sysasm权限，但无法在客户端连接到ASM实例，且没有报错。
1.ASM实例创建用户赋予sysasm权限
sqlplus / as sysasm
SQL> create user infa identified by infa;
User created.
SQL> grant sysasm to infa;
Grant succeeded.2.客户端tnsnames.ora配置
分别针对ASM实例1和实例2配置对应的信息：
ASM12c1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.90)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = +ASM)
(INSTANCE_NAME = +ASM1)
)
)
ASM12c2 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.92)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = +ASM)
(INSTANCE_NAME = +ASM2)
)
)因为是12c版本，无需配置UR=A，关于UR=A可参考之前的测试：
3.客户端测试连接
客户端测试连接ASM12c1:
[[email protected] admin]$ sqlplus infa/[email protected] as sysasm
