Afternoon all.

I've been working on a listener problem all day. Because there is quite 
a bit of evidence, I've posted the problem on my blog at 
http://t.co/ss0KHSbfSd - if you care to take a look and make any 
suggestions back here, I'd be very grateful!

The link above is a short form of 
http://qdosmsq.dunbar-it.co.uk/blog/2013/05/this-listener-problem-is-driving-me-mad/
 
- in case you are suspicious of short form links.

In summary, a database is running and so is the listener.

$ . oraenv<EOF
orcl11g
EOF

$ sqlplus user/password
...
SQL> select 'It Worked!' from dual
...

However, connecting via the listener results in carnage:

$ . oraenv<EOF
orcl11g
EOF

$ sqlplus user/password@orcl11g

ERROR:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Linux-x86_64 Error: 2: No such file or directory
Process ID: 0
Session ID: 0 Serial number: 0

I have Googled and MOS'd until I'm blue in the face. Just about 
everything says to start the database. Or, relates to a RAC SCAN - and 
this is a single instance database, no RAC in use.

Appreciate any info, as it is, driving me mad! However, please don;t 
respond until you have seen what I've already done at the above URL. 
Thanks. (And sorry! But I know someone will tell me to make sure 
ORACLE_HOME in listener.ora is correct and such like, trust me, I've 
been and done all that. I resolved this error yesterday on another 
server by exactly that method!)


Cheers,
Norm.
