Client gets message "z39.50 gate not running"

• Article Type: General
• Product: Aleph
• Product Version: 19.01

Description:
We are testing the 18 to 19 upgrade and I find that I can't search a z39.50 target from the within the v.19 client. After selecting a z39.50 target in the "Base" selection list of the Search tab in the Cataloging client and trying to perform a search the error message "z39.50 gate is not running" displays. I verified with Util W that the z39_gate was running and also stopped and restarted it to see if that would make a difference (also stopped and restarted the pc_server to be sure). So far nothing has fixed the problem. In the pc_server log I see the following:

SERVICE : C1011
MODULE : OPAC Services
DESCRIPTION: Send Find Request
ACTION :
PROGRAM : pc_sear_c1011

connect: No route to host

The "connect: No route to host" is particularly interesting. What does that error mean in the pc_server log? I have tried several institutions and so far they all are having the same problem.

Also, looking at the log for the z39_gate there seems to be no indication at all that it was communicated with by the client after I try to perform a z39.50 search.

Resolution:
I found this in aleph_start:

setenv Z39_HOST aserv33

However, when I echo $HOST, I get this:

>>echo $HOST
aserv32.usa.edu

Your Z39_HOST definition in aleph_start is defined incorrectly. aserv33 is a different server hosing your Oracle application. I found this in your aleph_start:

setenv ORA_HOST aserv33

You need to change the Z39_HOST definition to:

setenv Z39_HOST aserv32

In other cases the entry in aleph_start for Z39_HOST must be changed to the internal server address (don't use the the external address).
