[20181204]低版本toad 9.6直连与ora-12505.txt

[20181204]低版本toad 9.6直连与ora-12505.txt

--//我们生产系统还保留有一台使用AMERICAN_AMERICA.US7ASCII字符集的数据库,这样由于toad新版本不支持该字符集的中文显示.
--//我一直保留toad 9.6的版本,并且这个版本是32位的,我必须在我的机器另外安装10g 32位版本的客户端,这样才能连上数据库.

--//同事前一段时间遇到使用该版本的连接问题,我已经解决,链接:http://blog.itpub.net/267265/viewspace-2219005/

--//前几天同事告诉我配置tnsnames.ora连接没有问题.而使用toad下直连模式报ora-12505错误.数据库是18c的版本
--//TNS:listener does not currently know of SID given in connect descriptor

$ oerr ora 12505
12505, 00000, "TNS:listener does not currently know of SID given in connect descriptor"
// *Cause:  The listener received a request to establish a connection to a
// database or other service. The connect descriptor received by the listener
// specified a SID for an instance (usually a database instance) that either
// has not yet dynamically registered with the listener or has not been
// statically configured for the listener. This may be a temporary condition
// such as after the listener has started, but before the database instance
// has registered with the listener.
// *Action:
//  - Wait a moment and try to connect a second time.
//  - Check which instances are currently known by the listener by executing:
//    lsnrctl services <listener name>
//  - Check that the SID parameter in the connect descriptor specifies
//    an instance known by the listener.
//  - Check for an event in the listener.log file.

--//有点奇怪的是我明明直连使用服务名连接,为什么报TNS:listener does not currently know of SID given in connect descriptor.
--//而是有关sid的信息呢?

--//注意看服务名orcl里面指向的实例是orclcdb.
--//突然想起链接:http://blog.itpub.net/267265/viewspace-2140061/的测试.
--//从提示上也是
ORA-12505: TNS:listener does not currently know of SID given in connect descriptor
Warning: You are no longer connected to ORACLE.
--//我明明使用服务名连接访问数据库,为什么报sid之类的错误.

--//视乎toad 9.6版本的直连模式也很奇怪,视乎还要对上sid.
--//修改监听配置文件./u01/app/oracle/product/18.0.0/grid_home/network/admin/listener.ora
--//加入如下:
USE_SID_AS_SERVICE_listener=on

--//注意文件的位置,我们的数据库很特殊,单实例asm.要修改/u01/app/oracle/product/18.0.0/grid_home/network/admin/目录下的监听配置文件.
--//监听重启也要执行:
$ srvctl stop listener ; srvctl start listener

--//这样再使用toad下直连模式就没有任何问题,连接cdb与pdb都没有问题.
--//我最终发现这个版本的toad(9.6)有bug(服务名和sid一样连接就没有问题),如果使用使用toad 12以上版本没有这个问题.

--//我在我的测试环境配置如下:
