Can Some one please help me how to fix this

Thanks

Please try the following:

1. Run cmd.exe, then set NLS_LANG environment variable to say AMERICAN_AMERICA.UTF8,
   then from the same window start netxmsd

2. If #1 doesn't help run cmd.exe and check if the Oracle environment variables are ok
   (ORACLE_HOME, PATH to Oracle binaries, TNS_ADMIN) - if not set them to proper
   locations

3. If #1 and #2 dont help and you're using Oracle instant client try to specify fully
   qualified TNS name instead of SID in DBServer parameter of netxmsd.conf
   Please see explanation here:
   http://www.oracle.com/technology/tech/oci/instantclient/ic-faq.html#A4428

Hope this helps

The following messages is done at this try：

SQL> CREATE USER netxms IDENTIFIED BY netxms;

the user is created.

SQL> grant connect,resource to netxms;

authorized successfully。

SQL> select instance_name from v$instance;

INSTANCE_NAME
----------------
zhmg

and at command line,
c:\sqlplus netxms/netxms
can connect oracle successfully.

Bset regards

There are two problems with your netxmsd.conf:

• For Oracle, DBServer parameter must be set to your Oracle SID, not the hostname. This is the main problem which prevents NetXMS from connecting to your database
• Setting DBLogin to system (Oracle's administrator username) is a very very very bad idea. NetXMS doesn't need admin rights and by using "system" you are not only giving it full admin rights but also cluttering system schema with absolutely foreign objects. Please create a separate username, assign "connect" and "resource" roles to it and you'll be fine.

The proper netxmsd.conf file looks like this:

# Driver - Oracle
DBDriver = oracle.ddr
# Oracle SID (check tnsnames.ora)
DBServer = ODB1
# Not used by NetXMS Oracle driver
DBName = netxms_db
# Oracle user name (schema)
DBLogin = NETXMS
# Oracle user password
DBPassword = NETXMS
