Greetings All,

I am trying to connect to the Sybase database instance but I am unable to connect isql to Sybase database instance due to the following error:

CT-LIBRARY error:
ct_connect(): directory service layer: internal directory control layer error: : There was an error encountered while binding to the directory service

This error is most common error in case of connection failure.
Please check if sql.ini is correctly set. Check if ASE server is running.

All,

The Sybase instance I am working with is running on the Linux server.  And yes, the Sybase intance is running.  I receive this error message when I try to use Sybase isql on the Linux server.

When I submit the command:
isql -U myid -P mypw

I receive the following error message:
CT-LIBRARY error:
        ct_connect(): directory service layer: internal directory control layer error: Requested server name not found.

Any ideas are greatly appreciated.

Thank you.

All,

I just tried the following and it still does not work.  I am providing more information about the interfaces file entries.

[SERVERNAME]
query=TCP,10.202.16.82,2640

isql -U myid -P mypw -S query=TCP,10.202.16.82,2640

I am still getting the following error msg:
CT-LIBRARY error:
        ct_connect(): directory service layer: internal directory control layer error: Invalid syntax found in interfaces file.

Another question I have is there another Sybase configuration file, ie RUN_server file,  I need to check/use?

Any help is greatly appreciated.

Thank you.

That format is for Windows sql.ini file. Interfaces file format on UNIX/Linux platforms is different. You shouldn't edit interfaces file directly. You can use dscp to edit it.

I think you should restore original interfaces file and use isql by providing the actual server name:

isql -U myid -P mypw -S <SERVERNAME>

Alpmoon,

Thank you for the response.
The interfaces file I displayed in my previous comment is on the Linux server in the directory:
/opt/SYBASE

-rw-r--r--  1 root   root     41 Nov  3 06:32 interfaces

INTERFACES FILE
---------------------
[SERVERNAME]
query=TCP,10.202.16.82,2640

I did not create this file as I am just started working with this company.
So, you are saying I should change the interfaces to use a different format?

Let me know.
Thanks.

My comment was based on the message you got at your last post before mine:

"Invalid syntax found in interfaces file."

In your previous post the message was "Requested server name not found."

So it looks the files were different.

You can try dscp to check interfaces file:

$ dscp
>> open
ok
Session 1 InterfacesDriver>> list

Server objects found:
    XXXX
    XXXX_BS
