    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?


    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?
