I have changed the names of the database and server in this example.
I had a new Oracle 11.1 database, which I was trying to access remotely using an Oracle 11.2 listener:
Solaris > sqlplus /@XXXXXX
SQL*Plus: Release 11.2.0.1.0 Production on Tue Nov 6 18:25:48 2012
Copyright (c) 1982, 2009, Oracle. All rights reserved.
ERROR:
ORA-12537: TNS:connection closed
The following errors appeared in the listener log:
<msg time='2012-11-06T18:25:48.133+00:00' org_id='oracle' comp_id='tnslsnr'
type='UNKNOWN' level='16' host_id='xxx-xxxxxx-xxxx'
host_addr='99.99.9.999'>
<txt>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
Solaris Error: 32: Broken pipe
</txt>
</msg>
There is more than one possible reason for this. On this occasion the entry for the new database in the listener parameter file was as follows:
(SID_DESC =
(SID_NAME = XXXXXX)
(ORACLE_HOME = /oracle/app/oracle/product/11.1.0)
)
I added an extra line like this:
(SID_DESC =
(SID_NAME = XXXXXX)
(ORACLE_HOME = /oracle/app/oracle/product/11.1.0)
(ENVS="LD_LIBRARY_PATH=/oracle/app/oracle/product/11.1.0/lib")
)
I restarted the listener:
Solaris > lsnrctl reload listener_11
LSNRCTL for Solaris: Version 11.2.0.1.0 - Production on 06-NOV-2012 18:40:10
Copyright (c) 1991, 2009, Oracle. All rights reserved.
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=xxx-xxxxxx-xxxx)(PORT=1529)))
The command completed successfully

Then I was able to connect to the database remotely:
Solaris > sqlplus /@XXXXXX
SQL*Plus: Release 11.2.0.1.0 Production on Tue Nov 6 18:42:27 2012

Hello Andrew,
ReplyDeleteI faced with same issue. In my environment I using 12.1.0.2 listener and 11.2.0.3 database.
I traced tnslsnr process (truss -w 2 -fp ) and found that libodm11.so not found in path:

As you see libodm11.so searched first in ORACLE_HOME=/pub/home/m.velikikh/oracle/product/12.1.0.2
And after in standard OS places.
I added (ENVS = "LD_LIBRARY_PATH=/pub/home/m.velikikh/oracle/product/11.2.0.3.7/lib")
line into listener.ora and that's resolve my issue.
Best regards,
Mikhail.
