ORA-28547 on oracle 10g/solaris9/sun cluster

Question

I get an error ORA-28547 each time I try to connect to the running instance of from a host different than the one oracle is running on.
The listener.ora is as follows:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = IMA)
(ORACLE_HOME = /opt/oracle/app/oracle/product/10.1.0/db_1)
(PROGRAM = extproc)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = oracle-lh)(PORT = 1521))
the tnsnames.ora:
IMA =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = oracle-lh)(PORT = 1521))
(CONNECT_DATA =
# (SERVER = DEDICATED)
# (SERVICE_NAME = IMA)
(SID = IMA)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
and the sqlnet.ora:
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
any idea of what's wrong? A ps -ef reports this process running:
oracleIMA (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))
can PROTOCOL=beq be the cause of the mess?
Please help!!
Thanks in advance

Answer 1

In the block
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = IMA)
(ORACLE_HOME = /opt/oracle/app/oracle/product/10.1.0/db_1)
(PROGRAM = extproc)
you have to remove line (PROGRAM = extproc)
This line belongs to an external procedure call, not to a database instance, here's a simple example:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = C:\oracle\server)
(PROGRAM = extproc)
(SID_DESC =
(GLOBAL_DBNAME = Oracle.wkawollek.de)
(ORACLE_HOME = C:\Oracle\Server)
(SID_NAME = ORACLE)
)
