Oracle 11g client: TNS-illegal ADDRESS parameter

Question

Hi,
I am working on a database application. The application uses OCI interface to connect and query to the Oracle Database
The application used to work with Oracle 10g client, but using Oracle 11gR1 or 11gR2 client application is failing to connecto the Database
The sqlnet.log on client machine is showing following error
Fatal NI connect error 12533, connecting to:
(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=vm-oedsdev1)(PORT=1521))(CONNECT_DATA
=(SERVICE_NAME=orcl)(CID=(PROGRAM=_orasrv@bespin)(HOST=bespin)(USER=sgarg))))
VERSION INFORMATION:
TNS for Solaris: Version 11.1.0.6.0 - Production
TCP/IP NT Protocol Adapter for Solaris: Version 11.1.0.6.0 - Production
Time: 07-JUL-2011 05:48:50
Tracing to file: /scratch/sgarg/wrk/bug/OE00175173/oe102b/64bit/trace/cli_8585
.trc
Tns error struct:
ns main err code: 12533
TNS-12533: TNS:illegal ADDRESS parameters
ns secondary err code: 0
nt main err code: 0
nt secondary err code: 0
nt OS err code: 0
Following is my test environment
Platform and OS - Solaris 2.9 SPARC V9
Oracle client version - 11.1.0.6.0
Oracle Server version - 11.1.0.6.0
On Database server which is running on 64 bit Windows, listener log and listener trace have following error logs
listenr.log:
TNS-12502: TNS:listener received no CONNECT_DATA from client.
Following is the header of the listener.log file
TNSLSNR for 64-bit Windows: Version 11.1.0.6.0 - Production on 07-JUL-2011 09:04:56
listener.trc:
The corresponding listner trace has following trace entry
[07-JUL-2011 11:51:51:668] ntt2err: Read unexpected EOF ERROR on 460
The Oracle client (version 11.1.0.6.0) is running on Solrias 64 bit machine.
Please help me understanding why are these errors appearing with Oracle 11g client.

Sachin

Hi,
Thanks for your reply, but your assumption is incorrect that I did not read the error message in the documentation. I read it many times, but could not correlate it with any wrongdoing.
solaris64:102b$ oerr TNS 12533
12533, 00000, "TNS:illegal ADDRESS parameters"
// *Cause: An illegal set of protocol adapter parameters was specified. In
// some cases, this error is returned when a connection cannot be made to the
// protocol transport.
// *Action: Verify that the destination can be reached using the specified
// protocol. Check the parameters within the ADDRESS section of
// TNSNAMES.ORA. Legal ADDRESS parameter formats may be found in the
// Oracle operating system specific documentation for your platform.
// Protocols that resolve names at the transport layer (such as DECnet object
// names) are vulnerable to this error if not properly configured or names are
// misspelled.
The above says that, illegal set of protocol adapters was specified...., I am using 'Local Naming (tnsnames.ora)' connection method and using TCP/IP protocol.
Following are the tnsnames.ora content
solaris64:102b$ cat tnsnames.ora
oeora11g1 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = vm-oedsdev1)(PORT = 1521))
(CONNECT_DATA =
(service_name = orcl)
and the following are the sqlnet.ora content
solaris64:102b$ cat sqlnet.ora
# sqlnet.ora Network Configuration File: /gateways/solaris64/oracle/client/10.2/network/admin/sqlnet.ora
# Generated by Oracle configuration tools.
NAMES.DIRECTORY_PATH= (TNSNAMES, ONAMES)
DIAG_ADR_ENABLED=NO
trace_level_client=SUPPORT
trace_directory_client=/scratch/sgarg/wrk/bug/OE00175173/oe102b/64bit/trace
My bad that the information was not enough to comment on anything on the problem.
I think, the above info would be helpful
Thanks,
Sachin
