配置data guard broker时遇到的几个问题
primary: RAC
standby: instance
> primary database is 'tantest'
> connect identifier is tantest;
Error:
ORA-16525: the Data Guard broker is not yet available
ORA-06512: at "SYS.X$DBMS_DRS", line 228
ORA-06512: at line 1
DGMGRL> create configuration 'DRSoution' as
> primary database is 'tantest'
> connect identifier is tantest;
Error: ORA-16584: operation cannot be performed on a standby database
上面问题是必须连接到主库dgmgrl
> primary database is 'tantest'
> connect identifier by tantest;
connect identifier by tantest;
^
Syntax error before or at "by"

Error: ORA-16571: Data Guard configuration file creation failure
Failed.
这个问题是因为dg_broker_config_file1 指定的目录有问题：
我的源端是RAC环境，该目录在ASM中，目录路径没有写全，导致出现该问题。文件broker配置中会自动创建，但目录不会自动创建，必须写全。
> connect identifier is dgbro;
Error: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
SQL下连接正常，在dgmgrl下不正常。
原因是connect identifier is dgbro;读的dgbro是在主库的tnsname.ora中的，必须把主库的写正确。
