I have an application and when data in a table is updated a trigger is executed and sends information from oracle to sql server 2005.  This was working correctly and all of a sudden I began seeing the following error message:

Detail Message=java.sql.SQLException: ORA-28500: connection from ORACLE to a non-Oracle system returned this message: [Generic Connectivity Using ODBC][S1000] [9013]General error in nvITrans_BeginT - rc = -1. Please refer to the log file for details. ORA-02063: preceding 2 lines from KANCARD

I'm not sure why this error occurred or how to correct it.  Help is greatly appreciated as this is in our production environment.

kindly first check database link (from Oracle to sql server ).
check tns service alias using tnsping command.

If there is any issue with databas link then recreate database link from oracle to sql server

create database link ODBC connect to "sa" identified by "pencil" using 'hsodbc'.

If you encase the login and password in double quotes and the tnsnames reference in single quotes, then the connection between Oracle and MSSQL works perfectly.

The user and password does still exist as I was able to log in to SQL Server Mgmt Studio with it.

Prior to seeing this message I did drop the link and recreate the link which seemed to "fix" the problem.  I still have no idea what caused the problem and more importantly I have no idea when this problem is going to take us down again.  I know I can work around this problem by setting something up to schedule the link to be dropped and created at some given interval but I really would like to understand why this is happening and how to prevent/handle it rather than just blindly recreating the link.
