===Unable to Connect to Destination===

If you receive "TNS-12203: TNS: unable to connect to destination" errors, take the following action:

1. Use a text editor to open the oplrqb.ini file which you find in the /bin sub-directory of your <nop>OpenLink server components installation.

2. Locate the [generic_ora8xx] section which corresponds to your <nop>OpenLink Database Agent. For example:

{{{
[generic_ora81]
Program = ora81_mv.exe
Environment = ORACLE8
ReUse = always
;Directory = c:\temp
;ConnectOptions =
;ReadOnly =
;CommandLine =
;Database =
;UserID =
;Password =
}}}

3. Set the <nop>ReUse rule to "Never." For example:

{{{
[generic_ora81]
Program = ora81_mv.exe
Environment = ORACLE8
ReUse = Never
}}}

4. Save your changes and exit the file.

5. Restart your Broker.

6. Test.
