    Is it possible to change maximum connections for z39.50 server? How?

    • Product: Voyager
    • Relevant for Installation Type: Multi-Tenant Direct, Dedicated-Direct, Local


    It appears we are hitting the maximum connections (50) for the z39.50 server regularly. Is this a limit that is able to be changed? If so, how do we alter this?

    Answer (where xxxdb is the Voyager Database Instance) 

    1. SSH to server as voyager user
    2. cd /m1/voyager/xxxdb/ini/
    3. Open z3950svr.ini for editing
    4. Find this setting:

    # What is the maximum number of simultaneous client connections you'll accept? 

    1. Update the value for MaxSessions=
    2. Save changes
    3. Restart z3950svr process (or wait until after the nightly restart of Voyager)

    Always monitor the effects on your services when making such a change.

    Additional Information

    This setting works in tandem with the idle timeout period for Z39.50 connections.  See: How do I set the timeout period of the Z39.50 server?
