我的解决参考：http://www.itpub.net/thread-1870217-1-1.html
根据MOS：Troubleshooting Guide for TNS-12518 TNS listener could not hand off client connection (文档 ID 550859.1)中，
| Error: 32: Broken pipe
Error stack in listener log:
TNS-12518: TNS:listener could not hand off client connection TNS-12547: TNS:lost contact TNS-12560: TNS:protocol adapter error TNS-00517: Lost contact IBM/AIX RISC System/6000 Error: 32: Broken pipe
Cause: The error 32 indicates the communication has been broken while the listener is trying to hand off the client connection to the server process or dispatcher process.
Action: 1. One of reason would be processes parameter being low, and can be verified by the v$resource_limit view. 2. In Shared Server mode, check the 'lsnrctl services' output and see if the dispatcher has refused any connections, if so, then consider increasing the number of dispatchers. 3. Check the alert log for any possible errors. 4. Memory resource is also another cause for this issue. Check the swap, memory usage of the OS. 5. If RAC/SCAN or listener is running in separate home, check the following note:
Note: 1069517.1 ORA-12537 or TNS-12518 if Listener (including SCAN Listener) and Database are Owned by Different OS User
|
根据第5条，因为我的grid是11.2.0.1，而Oracle是11.2.0.3的，查询MOS:ORA-12537 / ORA-12547 or TNS-12518 if Listener (including SCAN Listener) and Database are Owned by Different OS User (文档 ID 1069517.1)，里边明确指出是由于$RDBMS_HOME/bin/oracle文件的权限问题导致。
1.3.4 故障解决
$ORACLE_HOME/bin/oracle文件的权限问题，应该为-rwsr-s--x，属主应该是oracle:asmadmin。
解决办法：
方法：
1、修改oracle的权限为6751
| [root@orcltest bin]# ll /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle -rwxr-s--x. 1 oracle asmadmin 210823844 May 18 2014 /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle [root@orcltest ~]# chmod 6751 /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle [root@orcltest bin]# ll /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle -rwsr-s--x. 1 oracle asmadmin 210823844 May 18 2014 /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle [root@orcltest bin]#
|
2、重新用setasmgidwrap设置oracle
| [root@orcltest bin]# ll /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle -rwxr-s--x. 1 oracle asmadmin 210823844 May 18 2014 /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle [root@orcltest ~]# /u01/app/11.2.0/grid/bin/setasmgidwrap -o /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle [root@orcltest bin]# ll /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle -rwsr-s--x. 1 oracle asmadmin 210823844 May 18 2014 /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle [root@orcltest bin]# [root@orcltest bin]# stat /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle File: `/u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle' Size: 210823844 Blocks: 411776 IO Block: 4096 regular file Device: 802h/2050d Inode: 1717737 Links: 1 Access: (6751/-rwsr-s--x) Uid: ( 501/ oracle) Gid: ( 504/asmadmin) Access: 2017-03-16 11:05:44.809363974 +0800 Modify: 2014-05-18 17:09:50.508549983 +0800 Change: 2017-03-16 12:33:15.733816820 +0800 [root@orcltest bin]# [root@orcltest bin]#

1.4 故障处理总结
如果可执行文件$ORACLE_HOME/bin/oracle的属主或权限设定出了问题，那么可能会造成很多问题。例如：无法登陆到数据库、ora-600错误、“TNS-12518: TNS:listener could not hand off client connection”、“Linux Error: 32: Broken pipe”、“ORA-12537: TNS:connection closed”、访问ASM磁盘出错等。解决办法很简单，可以在grid用户下运行setasmgidwrap命令重新配置$ORACLE_HOME/bin/oracle可执行文件的权限和属主或者直接将oracle文件的权限修改为6751。$ORACLE_HOME/bin/oracle可执行文件正确属主应该是oracle:asmadmin，并且权限必须有s共享才可以，如下所示：

问：在UNIX/LINUX环境中，oracle数据库启动后存在许多后台进程和前台进程，虽然相关进程产生一些trace文件也是常有的事情，但是真正是什么决定了oracle相关进程的属性呢？
答：通常来说，oracle的后台进程的调用是依赖于$ORACLE_HOME/bin/oracle这个二进制文件，但它从远端连入而分配的服务器进程（server process）相关属主的属性则是继承自listener进程，而listener进程的属主属性同样是进程自其启动的用户（分oracle用户和grid用户）$ORACLE_HOME/bin/oracle的属主属性。
其他原因：
启动ORACLE监听的时候 报错 Linux Error: 32: Broken pipe
原因：原来/home/oracle/product/9.2.0.1.0/network/log/listener.log 文件超过2G，监听就会断掉。
解决办法：清空日志文件
[oracle@localhost oracle]$ cd $ORACLE_HOME/network/log
[oracle@chicago log]$ cat listener.log
至此问题解决
有个命令可以对这个写日志进行关闭
LSNRCTL> set log_status off
要继续写日志，只需要
LSNRCTL> set log_status on
也可以在 listener.ora 文件里面添加一项
LOGGING_LISTENER = OFF
添加了这个之后无论你怎么重启监听，都不会写日志了。

PURPOSE
This article discusses how to troubleshoot the ORA-12518/TNS-12518 listener errors.
TROUBLESHOOTING STEPS
Section I: Steps to approach ORA-12518/TNS-12518 Error:
ORA-12518/TNS-12518 indicates a problem while listener hands off the client connection to the server process or dispatcher process.TNS-12518 is logged in the listener log. The client might receive ORA-12518 or some other disconnection errors like ORA-12537. Once TNS-12518 is noted in the listener log, follow the below steps to approach and resolve this error.
Let us have a small discussion about how actually database connections are made:
In Dedicated mode, database client contacts listener and supplies the SERVICE NAME of the database. Then listener spawns a dedicated server process and hands off the client connection to this dedicated server process. TNS-12518 indicates a problem while handing off the client connection to the server process.
In Shared Server mode, database client contacts listener and supplies the SERVICE NAME of the database. Then listener hands off the client connection to one of the dispatcher configured for that service. TNS-12518 indicates a problem while handing off the client connection to the dispatcher server process.
Though this error is logged in the listener log, the listener is just the messenger, ORA-12518/TNS-12518 is mostly related to RDBMS and OS resources.
Step 1. Is listener version compatible to the database
Check if you are using compatible listener version for your database version.
If the database is 8i then use 8i or 9i listeners only. 10g listeners are not compatible to work with 8i databases.
For 9i databases, 9i or 10g listeners can be used.
For 10g databases, only 10g listeners can be used.
The general rule is that use the higher version of the listener when there is a version mismatch between database and the listener.
Step 2. Gather more information from listener log
The first place you would look for the TNS-12518 error is the listener log. Usually the listener log would be located under $ORACLE_HOME/network/log directory. You can use 'lsnrctl status' command output to look for the location of the listener log file.
- - -
- - -
Listener Parameter File /ora10g/home_ora10g/network/admin/listener.ora
Listener Log File /ora10g/home_ora10g/network/log/listener.log
- - -
- - -
listener log gives the complete error stack and the database service name to which the client tried to connect to.
TNS-12518: TNS:listener could not hand off client connection
TNS-12547: TNS:lost contact
TNS-12560: TNS:protocol adapter error
TNS-00517: Lost contact
Linux Error: 32: Broken pipe
In the above example, listener log shows the complete error stack, the bottom error being 32 is the OS error. It also shows that the jdbc client from IP 10.10.10.3 has tried to connect to the database service 'test.oracle.com' and failed with the error 12518.
Look for the lowest error in the stack. That is the error we have to concentrate on and try to resolve it. In the above example, the lower error is 'Linux Error: 32: Broken pipe'.
Step 3. Are service handlers in blocked state
Check if the handlers are in blocked state. Check the output of the 'lsnrctl services'. Examine the status information under the database service name. From the listener log you would know which database service was affected by the 12518 error, now with the output of the 'lsnrctl services' under that service name gather more information.
Instance "db10g", status READY, has 2 handler(s) for this service...
Handler(s):
"DEDICATED" established:9 refused:0 state:ready
LOCAL SERVER
"D000" established:10 refused:0 current:0 max:972 state:ready
DISPATCHER
(ADDRESS=(PROTOCOL=tcp)(HOST=oid.mohan.com)(PORT=33487))
The highlighted state should be in 'ready' state for the connection to be successful. If the state is in 'blocked' then the connection are not possible. The state of a handler could be in blocked state in the following scenario:
i. The database parameter processes reached its value.
ii. The database is in the process of startup or shutting down.
In shared server mode, the number of dispatchers should be set according to the load that you expect. 'lsnrctl services' output shows the maximum number(max:997) of connections that the dispatcher would accept and the number connections refused (refused:0) by this dispatcher. If any connections refused by the dispatcher, then consider increasing the number of dispatchers.
If you are using PFILE edit init.ora and increase the dispatchers parameter. If you are using SPFILE you can dynamically increase the dispatchers parameter by the'alter system set' command.
Step 4. Is a local BEQ connection successful
Check if local BEQ connection to the database works fine. It also verifies if the database is up and in good condition to accept the connection. If the database is down or in a hung state then a connection request to the database by the listener will not be possible.
Connect to the database server via telnet or ssh and check if a local bequeath SQL*Plus connection works. In other words, issue:
sqlplus username/password [Enter]
This connection bypasses the listener and directly connects to the database via the BEQ (bequeath) protocol. If this fails, then the TNS-12518 listener error is simply a result of the database issue.
One such error is:
ORA-12560: TNS:protocol adapter error
A possible cause for this error on Microsoft Windows servers, is that the Windows Database Service has not yet been created (common when creating a "standby" instance).
Resolution for this would be to create the Windows Service first by using the "oradim" command (see the Database Admin guide for details on oradim and service creation).
Step 5. Has number of processes reached its limit?
If local BEQ is successful, check the below query
RESOURCE_NAME CURRENT_UTILIZATION MAX_UTILIZATION INITIAL_AL LIMIT_VALU
-------------------- ------------------- --------------- ---------- ----------
processes 249 250 250 250
sessions 54 82 280 280
- - - - - -
- - - - - -
Verify if the processes or sessions reached its limit value. If these database parameters reached its limit value, then consider increasing it accordingly.
In the above example, the processes parameter has been set to 250. It's MAX_UTILIZATION has reached the limit value of 250, so the processes parameter should be increased further to accomodate the number of incoming connections.
Edit the init.ora and set the processes parameter to a higher value. By default, if you just increase the processes it is enough, the sessions value would automatically be increased.
Check the alert.log for a corresponding error such as "ksvcreate" process failed, etc. Check timestamp against listener.log timestamps for causal relationship.
Step 6. Are OS kernel parameters configured for optimum?
Database is operated by a single user, normally it would be 'oracle' user. At the Operating System level, there is a limit for the number of process spawned by a user. And also there is a limit for the total number of process running on the entire OS.
The Oracle Database and the newly spawned processes would be owned by the 'oracle' user. And so make sure that these values are set accordingly.On Unix these values are configured through the configurable OS kernel parameters and is specific to Operating Systems. You will have check your corresponding OS documentation for your OS.
For example for HP-UX the configurable kernel parameters are,
maxuprc Maximum number of processes for each non-root user
nproc Maximum number of processes on the system
Step 7. Does alert log have any errors?
Look in alert log and look for any errors related to memory or process during the time the error TNS-12518 occurred in the listener log. If the alert log has any memory related errors, there there is a potential memory resource issue at the OS level.
OS memory issues can be addressed by the below:
i. Make sure that the OS has been configured with the enough Swap memory. In case of Windows it is called as Virtual Memory.
ii. Reduce the size of SGA, thus the newly spawned server process will have some more system memory available.
iii. Reduce the PGA size, so that the newly spawned server process would occupy less memory.
iv. If you are in DEDICATED mode, try switching to MTS mode.
To address memory issue for 32-bit Windows: Refer Note 371983.1
However, the errors in the alert logs are not being discussed in this article, they are out of the scope of this article.
Step 8. If using a statically defined SID_DESC in the listener.ora file for your sid, ensure that it is configured properly.
A common mistake is to include a (PROGRAM=EXTPROC) parameter:
(SID_LIST=
(SID_DESC =
(GLOBAL_DBNAME = ORCL.oracle.com)
(SID_NAME = ORCL)
(PROGRAM=extproc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)))
This misconfiguration occurs when the PLSExtproc SID_DESC is copied, pasted and edited in the listener.ora file. The inclusion of the PROGRAM line will cause an ORA-12518 to be returned to the client. Here's the corrected SID_DESC for our example SID:
(SID_LIST=
(SID_DESC =
(GLOBAL_DBNAME = ORCL.oracle.com)
(SID_NAME = ORCL)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)))
Section II: Commonly Known Errors:
This section lists some of the known and reported errors. It is also recommended that you refer the Section I above for a generic troubleshooting approach to the error TNS-12518.
Below shows example error stack that can be found in the listener log. The last line in the error stack shows the actual operating system name. Depending on the OS, only the operating system name would be different. For example, if you encounter error 32: Broken pipe, according to the OS, the last line in the error stack would be different only by the OS name, as shown below.
Solaris Error: 32: Broken pipe
HPUX Error: 32: Broken pipe
Linux Error: 32: Broken pipe
_______________________________________________________________________________________________________________________________________
Error: 32: Broken pipe
Error stack in listener log:
TNS-12518: TNS:listener could not hand off client connection
TNS-12547: TNS:lost contact
TNS-12560: TNS:protocol adapter error
TNS-00517: Lost contact
IBM/AIX RISC System/6000 Error: 32: Broken pipe
Cause:
The error 32 indicates the communication has been broken while the listener is trying to hand off the client connection to the server process or dispatcher process.
Action:
1. One of reason would be processes parameter being low, and can be verified by the v$resource_limit view.
2. In Shared Server mode, check the 'lsnrctl services' output and see if the dispatcher has refused any connections, if so, then consider increasing the number of dispatchers.
3. Check the alert log for any possible errors.
4. Memory resource is also another cause for this issue. Check the swap, memory usage of the OS.
5. If RAC/SCAN or listener is running in separate home, check the following note:
Note: 1069517.1 ORA-12537 or TNS-12518 if Listener (including SCAN Listener) and Database are Owned by Different OS User
______________________________________________________________________________________________________________________________________

TNS-12560: TNS:protocol adapter error
TNS-00519: Operating system resource quota exceeded
IBM/AIX RISC System/6000 Error: 11: Resource temporarily unavailable
Cause:
As the error indicates operating system resource has exceeded.
Action:
1. Increase the appropriate OS kernel parameters for 'maximum number of processes allowed per user'.
For example for HP-UX the parameters are maxuprc and nproc.

TNS-12560: TNS:protocol adapter error
TNS-00519: Operating system resource quota exceeded
IBM/AIX RISC System/6000 Error: 12: Not enough space
Cause:
This is a memory related issue. The error indicates that there is not enough memory available to spawn and hand off the client connections.
Typical problems are:
- Out of system memory / swap
- Out of process slots in the process table
- Streams resources depleted
- Out of File Handles
- sga memory usage
Action:
1. Check in the alert log for any possible memory related error.
2. Increase swap/Virtual memory if possible the available memory.
3. SGA and PGA can be reduced to address the memory consumption.
4. MTS mode can be used to reduce the amount of process and memory consumption.

Section III: Errors Specific to Windows
It is also recommended that you refer the Section I above for a generic troubleshooting approach to the error TNS-12518.
This section briefly describes about the errors that are encountered on Windows Operating System. TNS-12518 most commonly occurs on 32-bit OS due to its memory constraint, however TNS-12518 can occur on 64-bit OS as well. See Note 873752.1 for more information on Windows memory addressing and the 3GB switch.

SYMPTOMS
In environment where listener home (including SCAN listener which resides in GRID Infrastructure/ASM home) and database home are owned by different OS user, ORA-12537 could happen when connecting through listener, when creating database through DBCA, or when installing database software and creating a database in runInstaller. Job Role Separation is a typical example as SCAN and local grid home listener is owned differently than database.

// *Action: None needed; this is an information message.
Before the error is reported, connection could hang for a while, and a core file may also be generated.

SEVERE: [FATAL] [INS-30502] No ASM disk group found.
CAUSE: There were no disk groups managed by the ASM instance +ASM1.
CAUSE
1. In environments where the listener is not run in the same ORACLE_HOME where the database resides, the listener owner (including SCAN listener) may not be able to access the oracle binary in the database home. This is common in RAC or whenever a GRID_HOME and a database ORACLE_HOME are installed.
As listener owner:
ls: /home/oracle/app/oracle/product/11.2/db/bin/oracle: Permission denied
2. Oracle binary in database home has wrong permission:
-rwxr-x--x 1 oracle asmadmin 184286251 Aug 9 16:25 /home/oracle/app/oracle/product/11.2/db/bin/oracle
The permission "-rwxr-x--x" is wrong as it's missing suid bit, oracle binary should have permission of 6751:
Note: If Job Role Separation is in place, the group will be , otherwise it will be
3. File System for database home does not support setuid/suid or has nosetuid/nosuid set:
/home/oracle on /dev/dsk/diskoracle read/write/nosuid..
4. RDBMS_HOME/lib has wrong ownership/permission:
As listener owner:
ls: /home/oracle/app/oracle/product/11.2/db/lib: Permission denied
5. Another cause may be permissions on the RDBMS Directory structure or Home directory which needs to be accessed by the CRS user.
Check that the RDBMS $ORACLE_HOME is set to 755.
This can be seen from an OS trace such as strace or truss when using it to trace the CRS user running the "oracle" executable which fails with the "Permission denied" error.
Also:
a) Log in as the "GRID" user on each node, and issue the following (on each directory under the RDBMS Home) :-
ls: cannot open directory /u01/app/oracle: Permission denied
***NOTE: the Oracle directory has 700 for the permissions, which should be changed to 755:
Current (incorrect) -->
drwx------. 8 oracle oinstall 4096 Oct 12 08:38 oracle
Should be (correct) -->
drwxr-xr-x. 8 oracle oinstall 4096 Oct 12 08:38 oracle
b) Likewise the /product directory has 700 perms, so change to 755 -->
ls: cannot open directory /u01/app/oracle/product: Permission denied
Current (incorrect) -->
drwx------. 3 oracle oinstall 4096 Oct 12 08:58 product
Should be (correct) -->
drwxr-xr-x. 3 oracle oinstall 4096 Oct 12 08:58 product
c) Now a connection should work:
SQL>
SOLUTION
Solution is to make sure file system for database home has setuid/suid set, database binary($RDBMS_HOME/bin/oracle) has correct ownership and permission, and listener owner is able to access database oracle binary (as listener owner, "ls -l $RDBMS_HOME/bin/oracle" will tell)

CAUSE
Extensive paging/swapping activity is a clear indication that the system is running out of the physical memory.
SOLUTION
Solution :
1. Increase the physical memory of the system.
OR
2. Apply the Patch 6139856 for unpublished Bug 6139856 if available for your platform.
OR
3. Configure Hugepages on the OS. Ref : Note 361323.1
A Note on HugePages:
Hugepages is a mechanism that allows the Linux kernel to utilise the multiple page size capabilities of modern hardware architectures. Its important to know that utilising a huge amount of physical memory with the default page size consumes the TLB and adds processing overhead. The Linux kernel is able to set aside a portion of physical memory to be able be addressed using a larger page size. Since the page size is higher, there will be less overhead managing the pages with the TLB. In the Linux 2.6 series of kernels, hugepages is enabled using the CONFIG_HUGETLB_PAGE feature when the kernel is built. Systems with large amount of memory can be configured to utilise the memory more efficiently by setting aside a portion dedicated for hugepages. The actual size of the page is dependent on the system architecture. A typical x86 system will have a Huge Page Size of 2048 kBytes. The huge page size may be found by looking at the /proc/meminfo :
# cat /proc/meminfo |grep Hugepagesize Hugepagesize: 2048 kB
For more on configuring Hugepages please refer Note 361323.1

Cause:
Action:
2. In Shared Server mode, check the 'lsnrctl services' output and see if the dispatcher has refused any connections, if so, then consider increasing the number of dispatchers.
4. Memory resource is also another cause for this issue. Check the swap, memory usage of the OS.

鉴于当时操作系统有100多天没有重启过了，于是在2014-12-12 23：00重启了一下Linux服务器，到目前为止已经运行了3天，暂时没有出现这个错误。因为有可能一些内存泄露也会导致内存资源不足情况，例如，TNSListener Leaking Memory Using Dedicated Server (文档 ID 785742.1)。所以暂时没有实施上面方案2、3、想运行一段时间，验证一下自己的想法，如果还是出现这个错误，则尝试方案2、3、

--------------------------------------------------------------------------------------------------------------算是oracle bug问题了，当操作系统物理内存不足，swap/page 耗尽，将会导致listener异常崩溃。
而且从操作系统日志中，可以看到linux自己kill 进程的信息(由于事后总结，且信息在内网内，权限有限，贴不出日志内容)。
所以我的理解就是，当操作系统物理内存居高不下，操作系统会自己杀掉一些他认为的空闲进程之类，而不巧，杀掉的恰好是oracle的监听进程，
从而导致监听异常崩溃。
之所以说恰好是监听进程，是因为在/var/log/messages中，看到之前也有杀掉oracle进程的信息，但当时监听并未停掉，所以怀疑当时杀掉的并不是oracle监听进程，可能是其他非本地进程。

重启数据库服务器2次，也没弄好、。
| 问题解决，结贴。 方法： 1、修改oracle.exe的权限为6751; [oracle@jkxtrac1 bin]$ ls -l ./oracle -rwxr-s--x 1 oracle asmadmin 239627031 Jan 21 18:59 ./oracle [oracle@jkxtrac1 bin]$ ls -l oracle -rwxr-s--x 1 oracle asmadmin 239627031 Jan 21 18:59 oracle [oracle@jkxtrac1 bin]$ chmod 6751 oracle [oracle@jkxtrac1 bin]$ ls -l oracle -rwsr-x--x 1 oracle asmadmin 239627031 Jan 21 18:59 oracle 2、重新用setasmgidwrap设置oracle.exe [root@jkxtrac1 ~]# cd /data/app/11.2.0/grid_1/bin/ [root@jkxtrac1 bin]# ./setasmgidwrap o=/home/oracle/app/oracle/product/11.2.0/dbhome_1/bin/oracle 感谢各位朋友的帮助；； |
