oracle11g - Oracle 11gR2 Listener stop automatically -


my problem after started oracle listener succesfully, stop automatically after few seconds.

cache1-> lsnrctl start  lsnrctl linux: version 11.2.0.1.0 - production on 20-may-2013 16:35:36  copyright (c) 1991, 2009, oracle.  rights reserved.  starting /u01/app/oracle/product/11.2.0/db_1/bin/tnslsnr: please wait...  tnslsnr linux: version 11.2.0.1.0 - production system parameter file /u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora log messages written /u02/ora/diagnostic_dest/diag/tnslsnr/cache1/listener/alert/log.xml listening on: (description=(address=(protocol=tcp)(host=127.0.0.1)(port=1521)))  connecting (description=(address=(protocol=tcp)(host=127.0.0.1)(port=1521))) status of listener ------------------------ alias                     listener version                   tnslsnr linux: version 11.2.0.1.0 - production start date                20-may-2013 16:35:36 uptime                    0 days 0 hr. 0 min. 0 sec trace level               off security                  on: local os authentication snmp                      off listener parameter file   /u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora listener log file         /u02/ora/diagnostic_dest/diag/tnslsnr/cache1/listener/alert/log.xml listening endpoints summary...

during mean time, tnsping other server worked.

cache2-> tnsping cache1  tns ping utility linux: version 11.2.0.1.0 - production on 20-may-2013 16:35:38  copyright (c) 1997, 2009, oracle.  rights reserved.  used parameter files:  used hostname adapter resolve alias attempting contact (description=(connect_data=(service_name=))(address=(protocol=tcp)(host=192.168.1.2)(port=1521))) ok (0 msec)

after few seconds, check again, stopped automatically:

cache1-> lsnrctl status  lsnrctl linux: version 11.2.0.1.0 - production on 20-may-2013 16:36:36  copyright (c) 1991, 2009, oracle.  rights reserved.  connecting (description=(address=(protocol=tcp)(host=127.0.0.1)(port=1521))) tns-12541: tns:no listener  tns-12560: tns:protocol adapter error   tns-00511: no listener    linux error: 111: connection refused

and tnsping doesn't work.

cache2-> tnsping cache1  tns ping utility linux: version 11.2.0.1.0 - production on 20-may-2013 16:36:37  copyright (c) 1997, 2009, oracle.  rights reserved.  used parameter files:  used hostname adapter resolve alias attempting contact (description=(connect_data=(service_name=))(address=(protocol=tcp)(host=192.168.200.2)(port=1521))) tns-12541: tns:no listener

the listener.ora:

/u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora sid_list_listener =   (sid_list =     (sid_desc =       (sid_name = ora)       (global_dbname = ora)       (oracle_home = /u01/app/oracle/product/11.2.0/db_1)     )   )  listener =       (description =       (address = (protocol = tcp)(host = 127.0.0.1)(port = 1521))     )  adr_base_listener = /u02/ora/diagnostic_dest

thanks

faced simillar issue oracle11gr2 in rhel 6.x...

not sure if same issue ...check log.xml file trc log location in case:

/u01/app/oracle/diag/tnslsnr/dbserver/listener/alert/log.xml

from above file got link following log file:

/u01/app/oracle/diag/tnslsnr/dbserver/listener/trace/listener.log

the above file, checked , keep getting following :

warning: subscription node down event still pending 13-feb-2017 17:28:42 * (connect_data=(cid=(program=)(host=dbserver)(user=oracle))(command=status)(arguments=64)(service=listener)(version=186647040)) * status * 0 warning: subscription node down event still pending

after googling little bit found info in "https://docs.oracle.com/cd/e11882_01/network.112/e10835/listener.htm#netrf312" need add following @ end of listener.ora 

/u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora  subscribe_for_node_down_event_listener = off
