Hi Paul,
<div class=""><br class="">
</div>
<div class="">
<div class=""> You can enable the keepAlive on the client object with</div>
<div class="">conn.c.enableKeepAlive(300)</div>
<div class="">See 5.2 docs: <a href="https://downloads.openmicroscopy.org/omero/5.2.0/api/omero/client.html#enableKeepAlive-int-" class="">
https://downloads.openmicroscopy.org/omero/5.2.0/api/omero/client.html#enableKeepAlive-int-</a> </div>
<div class=""><br class="">
</div>
<div class="">Also you can set this in the etc/omero.properties file.</div>
<div class="">See discussion at <a href="https://www.openmicroscopy.org/community/viewtopic.php?f=6&t=495" class="">

<div class="">Dear OMERO Users/Developers,<br class="">
<br class="">
I'm writing a client application which connects to an OMERO server through a BlitzGateway object but I get a lost-connection exception. Could someone please advise me on how to keep a connection open? The snippet of code is roughly the following:<br class="">
<br class="">
conn = omero.gateway.BlitzGateway(...)<br class="">
roi = <some large ROI object><br class="">
conn.getUpdateService().saveObject(roi)<br class="">
<br class="">
Please see the traceback below:<br class="">
