Answers to: 64bit Server and 32bit Clientshttps://answers.axonivy.com/questions/2921/64bit-server-and-32bit-clients<p>Hi all,</p> <p>I was wondering if I can use a 64-bit Engine with increased java memory (we used 8GB in the server config file) in combination with 32-bit Clients. </p> <p>We are using an Ivy application with ULC, the engine is running on version 6.0.11 and struggle with the situation that we can run the server but clients will not start. It looks like that the 8GB configuration of the server is transfered to the clients which cannot use that amount of memory (32-bit) and therefore fail to start.</p> <p>Do I miss something here or is this combination of 64-bit server and 32-bit clients not possible.</p> <p>Thx and BR,</p> <p>Gerald</p>enFri, 20 Oct 2017 09:48:18 -0400Comment by Gerald on Christian Strebel's answerhttps://answers.axonivy.com/questions/2921/64bit-server-and-32bit-clients#2923<p>Thx, thats helped a lot :)</p>GeraldFri, 20 Oct 2017 09:48:18 -0400https://answers.axonivy.com/questions/2921/64bit-server-and-32bit-clients#2923Answer by Christian Strebelhttps://answers.axonivy.com/questions/2921/64bit-server-and-32bit-clients/2922<p>Hi</p> <p>If you mean the config in "configuration/jnlpconfig.any" there you can only change the memory settings of the ULC/RIA clients. To change the memory settings of the of the enine itself:</p> <p>Windows (<a href="https://developer.axonivy.com/doc/latest/EngineGuideHtml/misc.html#misc-toolreference-ilc">See docu</a>):</p> <ul> <li>Copy the Example.ilc file and rename it to AxonIvyEngine.ilc (or AxonIvyEngineService.ilc if you use the windows service to start the engine)</li> <li> <p>Change the property "ivy.heap.max.size" to your desired value in Mega bytes. E.g.:</p> <p>ivy.heap.max.size=4096</p> </li> </ul> <p>Linux (<a href="https://developer.axonivy.com/doc/latest/EngineGuideHtml/misc.html#misc-toolreference-unix">See docu</a>):</p> <ul> <li> <p>Set the Xmx as you like in the bin/AxonIvyEngine.conf file. E.g.:</p> <p>JAVA_OPTS="$JAVA_OPTS -Xmx4g"</p> </li> </ul>Christian StrebelFri, 20 Oct 2017 07:51:36 -0400https://answers.axonivy.com/questions/2921/64bit-server-and-32bit-clients/2922
