goldengate ERROR: Failed to open data source for user OGG
今日做veridata软件的测试，需要先配置一个用goldengate同步数据的环境，在目标端配置goldengate的复制进程时，使用dblogin userid ogg,password ogg命令出现错误ERROR: Failed to open data source for user OGG，纠结了一两天了，都不知道是什么问题，好在现如今终于得到解决。配置goldengate环境是win 2008操作系统，数据库为11g。
在目标端安装完goldengate,启动了mgr进程，globals文件也配置好，执行如下命令报错：
[*]GGSCI (WIN-RDG14W8R3AD) 1> info all
[*]
[*]Program Status Group Lag Time Since Chkpt
[*]
[*]MANAGER RUNNING
[*]
[*]
[*]GGSCI (WIN-RDG14W8R3AD) 2> dblogin userid ogg,password ogg
[*]ERROR: Failed to open data source for user OGG.
[*]
[*]GGSCI (WIN-RDG14W8R3AD) 3> dblogin userid ogg,password ogg
[*]ERROR: Failed to open data source for user OGG.
[*]
[*]GGSCI (WIN-RDG14W8R3AD) 4> dblogin userid ogg@localhost:1521/gc,password ogg
[*]ERROR: Failed to open data source for user OGG@LOCALHOST:1521/GC.
于是，开始排查对于权限，已给goldengate用户授予connect,resouce,dba角色，所以在权限上ogg用户是没有问题的；是不是监听的问题呢？
查看监听没问题，但是如果用sqlplus ogg/ogg@localhost:1521/gc 和 sqlplus ogg/ogg@127.0.0.1:1521/gc 都连接不进去，而使用sqlplus ogg/ogg@192.168.88.18:1521/gc
可以连接进去，监听文件内容如下：
[*]sqlnet.ora内容：
[*]SQLNET.AUTHENTICATION_SERVICES= (NTS)
[*]
[*]NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
[*]
[*]listener.ora内容：
[*]LISTENER =
[*](DESCRIPTION_LIST =
[*] (DESCRIPTION =
[*] (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.88.18)(PORT = 1521))
[*] )
[*])
[*]
[*]tnsnames.ora内容：
[*]GC =
[*](DESCRIPTION =
[*] (ADDRESS_LIST =
[*] (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.88.18)(PORT = 1521))
[*] )
[*] (CONNECT_DATA =
[*] (SERVER = DEDICATED)
[*] (SERVICE_NAME = gc)
[*] )
[*])
查看host文件内容：
[*]127.0.0.1 localhost
[*]::1 localhost
[*]192.168.88.18 WIN-RDG14W8R3AD
准备重新配置监听，将listener.ora 和tnsnames.ora里面的host值 改成主机名，然后监听重启，接着用
sqlplus ogg/ogg@localhost:1521/gc 和 sqlplus ogg/ogg@127.0.0.1:1521/gc
sqlplus ogg/ogg@192.168.88.18:1521/gc和 sqlplus ogg/ogg@WIN-RDG14W8R3AD:1521/gc 四种方式都可以连接进去。
下面再次使用dblogin命令，
[*]GGSCI (WIN-RDG14W8R3AD) 6> info all
[*]
[*]Program Status Group Lag Time Since Chkpt
[*]
[*]MANAGER STOPPED
[*]
[*]
[*]GGSCI (WIN-RDG14W8R3AD) 7> dblogin userid ogg,password ogg
[*]ERROR: Failed to open data source for user OGG.
[*]
[*]GGSCI (WIN-RDG14W8R3AD) 8> dblogin userid ogg@gc,password ogg
[*]ERROR: Failed to open data source for user OGG@GC.
[*]
[*]GGSCI (WIN-RDG14W8R3AD) 9> dblogin userid ogg@localhost:1521/gc,password ogg
[*]Successfully logged into database.
看到没，这次进去了。。。。。
------------------------------------------实验遇错排错记录。中间有重新建用户重配一样没解决问题。最后发现还是监听引起的问题。
