===Requested server name not found===


Sybase returns the following lengthy error, when the DSQUERY variable has not been set:

{{{
([Sybase Server]) ct_connect(): directory service layer: internal directory control layer error: Requested server name not found.
}}}

If you experience "server name" errors, take the action, which corresponds to your drivers:

**Multi-Tier Drivers**

1. Use a text editor to open your <nop>OpenLink Session Rules Book (oplrqb.ini). You will find the Session Rules Book in the /bin sub-directory of your <nop>OpenLink installation.

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

{{{
[Environment SYBASE12]
DSQUERY = SYBASE
SYBASE = C:\SYBASE
Path = C:\SYBASE\DLL;C:\WINNT\System32
CURSOR_SENSITIVITY = LOW ; Set to HIGH after loading oplrvc.sql
}}}

3. Insure that the correct value is passed to your DSQUERY variable. For example:

{{{
DSQUERY = SATURNUS
}}}

4. Save your changes and exit the file.

5. Restart your Request Broker.

6. Test.



**Single-Tier Drivers** 

1. Open your Single-Tier Data Source.

2. Click on the <nop>NetLib(Sybase) tab.

3. Locate the Server Name: field.

4. Place the appropriate DSQUERY variable in this Server Name: field.

5. Apply your changes.

6. Test.
