客户端不能正常连接oracle，监听状态为"Not All Endpoints Registered"

1,现象描述，应用反应不能正常

2,经过查询，原因如下，数据库起了两个listener，一个oracle用户起的，一个grid用户启动；正常情况下，应该只有grid用户起的
[grid@sdcmpdb1 ~]$  ps -ef|grep LISTENER
oracle    8317     1  0 15:41 ?        00:00:01 /oracle/app/oracle/product/11.2.0/db_1/bin/tnslsnr LISTENER -inherit
grid     14518     1  0 15:47 ?        00:00:00 /oracle/11.2.0/grid/bin/tnslsnr LISTENER -inherit
grid     21614 21346  0 16:45 pts/0    00:00:00 grep LISTENER
3，停掉一个后，应该恢复正常了
[grid@sdcmpdb1 ~]$ ps -ef|grep LISTENER
grid     14518     1  0 15:47 ?        00:00:00 /oracle/11.2.0/grid/bin/tnslsnr LISTENER -inherit
grid     21895 21724  0 16:49 pts/0    00:00:00 grep LISTENER
4，metailink上也有此报错的文章，主要是listener端口被占用导致不能正确启动导致
Cause

The problem is caused by another listener defined statically in listener.ora, using the same port and IP is running from the RDBMS ORACLE_HOME, started manually causing the default listener starting from GRID_HOME can not register its endpoint. Hence the error reported in dbca.
ps -ef | grep tns:

grid   7222 1 0 Apr26 ? 00:00:13 /u01/app/11.2.0/grid/bin/tnslsnr LISTENER_SCAN1 -inherit
grid   7237 1 0 Apr26 ? 00:00:13 /u01/app/11.2.0/grid/bin/tnslsnr LISTENER -inherit
oracle 7354 1 0 Apr26 ? 00:00:01 /u02/app/oracle/product/11.2.0/db/bin/tnslsnr LISTENER -inherit


   Another possible cause is the listener or scan listener being defined manually in listener.ora, for example:
LISTENER_SCAN3 =                          
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = racnode1)(PORT = 1523))
  )

LISTENER_SCAN1 =                           
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = racnode1)(PORT = 1521))

  

  
Solution

From 11.2 onwards, all listeners should be runing from GRID_HOME, listener and listener_scan<n> entry should be added automatically into listener.ora, no manual editing is required for TCP definition.

1. Stop the listener running from RDBMS ORACLE_HOME

$<RDBMS ORACLE_HOME>/bin/lsnrctl stop LISTENER

2. stop the listener from GRID_HOME

$<GRID_HOME>/bin/srvctl stop listener -n <node name>
$<GRID_HOME>/bin/srvctl stop scan_listener -i <scan#>

eg:

$<GRID_HOME>/bin/srvctl stop listener -n racnode1
$<GRID_HOME>/bin/srvctl stop scan_listener -i 1

If above command fails to stop the tnslsnr process, please use "kill -9 <pid of tnslsnr>" to stop the LISTENER and LISTENER_SCAN1 process.

3. remove any manually added LISTENER definition from listener.ora if it exists

4. restart the LISTENER and LISTENER_SCAN1  from GRID_HOME

$<GRID_HOME>/bin/srvctl start listener -n <node name>
$<GRID_HOME>/bin/srvctl start scan_listener -i <scan#>

5. check crsctl stat res -t output, they both should show ONLINE status now.
