启动listener遇TNS-12555/ TNS-12560 /TNS-00525错误处理

1、问题现象

    在oracle用户下，以lsnrctl start命令启动listener时，遭遇TNS-12555/ TNS-12560 TNS-00525错误，详细报错信息如下：

[oracle@ol6-single ~]$ lsnrctl start   LSNRCTL for Linux: Version 11.2.0.3.0 - Production on 25-OCT-2015 15:56:43 Copyright (c) 1991, 2011, Oracle.  All rights reserved. Starting /dba/oracle/product/11.2.0/db_1/bin/tnslsnr: please wait...   TNSLSNR for Linux: Version 11.2.0.3.0 - Production System parameter file is /dba/oracle/product/11.2.0/db_1/network/admin/listener.ora Log messages written to /dba/oracle/diag/tnslsnr/ol6-single/listener/alert/log.xml Listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=ol6-single)(PORT=1521))) Error listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521))) TNS-12555: TNS:permission denied  TNS-12560: TNS:protocol adapter error   TNS-00525: Insufficient privilege for operation    Linux Error: 1: Operation not permitted

2、问题分析

    上面报错信息，其实是很清晰的报出，是因为权限问题所导致的不能正常启动。

    但是，到底是哪个文件的权限不足所导致的呢？这个很关键。

    经过在metalink上找到一篇文档 ID 434062.1  的文章，文章中列出的CHANGES列出的内容如下：

Some IPC keys have been reused from older listener(s) Same listener has previously been started under different OS users Listeners running under different OS users are using the same IPC keys Permissions in /var/tmp have been previously reset.

    上面四点，前面三点笔者均经过了验证，实际情况是不存在问题的，现在目标直奔第四点，/var/tmp的权限。

    /var/tmp目录下只有一个隐藏文件夹，那就是.oracle，文章中的CAUSE 中也指出：

Older IPC socket file(s) were left in /var/tmp/.oracle and they cannot be deleted by the listener upon startup.

    现在看到是/var/tmp/.oracle文件夹或其下级文件夹的权限问题了。

3、问题解决

#chmod -R 777 /var/tmp/.oracle

 

下面来验证问题解决效果：

[oracle@ol6-single .oracle]$ lsnrctl start  LSNRCTL for Linux: Version 11.2.0.3.0 - Production on 25-OCT-2015 16:12:09  Copyright (c) 1991, 2011, Oracle.  All rights reserved.  Starting /dba/oracle/product/11.2.0/db_1/bin/tnslsnr: please wait...   TNSLSNR for Linux: Version 11.2.0.3.0 - Production System parameter file is /dba/oracle/product/11.2.0/db_1/network/admin/listener.ora Log messages written to /dba/oracle/diag/tnslsnr/ol6-single/listener/alert/log.xml Listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=ol6-single)(PORT=1521))) Listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(KEY=EXTPROC1521)))   Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=ol6-single)(PORT=1521))) STATUS of the LISTENER ------------------------ Alias                     LISTENER Version                   TNSLSNR for Linux: Version 11.2.0.3.0 - Production Start Date                25-OCT-2015 16:12:32 Uptime                    0 days 0 hr. 0 min. 0 sec Trace Level               off Security                  ON: Local OS Authentication SNMP                      OFF Listener Parameter File   /dba/oracle/product/11.2.0/db_1/network/admin/listener.ora Listener Log File         /dba/oracle/diag/tnslsnr/ol6-single/listener/alert/log.xml Listening Endpoints Summary...   (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=ol6-single)(PORT=1521)))   (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(KEY=EXTPROC1521))) The listener supports no services The command completed successfully

   Listener启动成功，问题解决。
