Ok, here is one solution.
Why this suddenly works today is beyond me. It is exactly
what I had done before I put this post on! Yet another one of
computing's great mysteries ...
ORACLE DBA SUBJECTS
- CONFIGURING THE LISTENER TO WORK WITH TWO DIFFERENT INSTANCES OF
ORACLE
- using one listener.ora file, and only one port for all databases
- Use the listener.ora file from the latest version of Oracle
- put the different paths for each database in the listener.ora file.
If the database was created in 805, use this path.
- in the .profile for the Unix user that starts Oracle, use the
ORACLE_HOME from the latest version of Oracle
LISTENER =
(ADDRESS_LIST =
(ADDRESS= (PROTOCOL= IPC)(KEY= PNPKEY))
(ADDRESS= (PROTOCOL= TCP)(Host= blue)(Port= 1521))
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(ORACLE_HOME= /apps/oracle/product/805)
(SID_NAME = JUNK805 )
)
(SID_DESC =
(ORACLE_HOME= /apps/oracle/product/734)
(SID_NAME = JUNK )
)
)
LSNRCTL> start
Starting /apps/oracle/product/805/bin/tnslsnr: please wait...
Services Summary...
JUNK has 1 service handler(s)
JUNK805 has 1 service handler(s)
