然后在listener.ora, tnsnames.ora中,dbname因为CDB, PDB是不同的,可以单独配置。以下是listener.ora

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(GLOBAL_DBNAME = G_ORCL)

(ORACLE_HOME = /app/oracle/product/12.1.0/dbhome_1)

(SID_NAME = GORCL)

)

(SID_DESC =

(SID_NAME = CLRExtProc)

(ORACLE_HOME = /app/oracle/product/12.1.0/dbhome_1)

(PROGRAM = extproc)

)

(SID_DESC =

(GLOBAL_DBNAME = P_ORCL)

(ORACLE_HOME = /app/oracle/product/12.1.0/dbhome_1)

(SID_NAME = GORCL)

)

)

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.89.134)(PORT = 1521))

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

)

)


以下是tnsnames.ora

PORCL =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.89.134)(PORT = 1521))

)

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = G_ORCL)

)

)

GORCL =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.89.134)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = G_ORCL)

)

)

所以使用tnsping是针对上面tnsnames.ora中的设置建立的,都是指向同一个service,因此其实只有一个service。

直接连接到PDB的方法如下:

OGG针对db12c多租户只需要配置一个extract,指向多个pdb;然后使用多个传输进程传输不同PDB的数据到目标端,当然也可以只用一个传输进程。
目标端针对不同的PDB,必须配置不同的rep进程。
