CT Library call fails - ct_connect() - HP-UX

Hi All,

I am using Sybase Open Client on HP-UX B.11.11 U 9000/800. I
am trying to use ct_connect in my application. This call
fails with the follwoing error:

-----
ct_connect(): network packet layer: internal net library
error: Net-Lib protocol driver call to connect two endpoints
failed
-----
Note that SHLIB_PATH is set to $SYBASE_OCS/lib.

However, when I try doing the same with SHLIB_PATH set to
$SYBASE_OCS/devlib (debug libraries), the ct_connect call is
successful.

Could someone please exaplin the difference in behaviour
between the two cases?

Note that I am able to connect to the sybase server using
isql.

Thanking in advance,
Reshma

Hello,

That error should not have anything to do with using
the devlib versus the normal production lib. That
error indicates a problem with the "interfaces" file.
It means that the server/port combination specified
in the "interfaces" file is incorrect or the server is
not running and listening to that port.

The SHLIB_PATH should not be set to $SYBASE_OCS/lib.
You must specify the entire path to that directory:
SHLIB_PATH = $SYBASE/$SYBASE_OCS/lib

What is the difference between your application and
the ISQL program? Is your application multithreaded?
If so, did you link with the threadsafe libraries?
(The threadsafe libraries have an "_r" in their names,
assuming that you are using 12.5 or 12.5.1).

Can you compile and run any of the sample programs in
the $SYBASE/$SYBASE_OCS/sample/ctlibrary directory?

If they can connect, what is different between these
applications and yours?

Thanks,
Neal
