When hosting multiple views in Ambari, it is strongly recommended you increase the amount of memory available available to the Ambari Server. Since each view requires it’s own memory footprint, increasing the Ambari Server maximum allocable memory will help support multiple deployed views and concurrent use.

1. On the Ambari Server host, edit the ambari-env.sh file:

   vi /var/lib/ambari-server/ambari-env.sh

2. For the AMBARI_JVM_ARGS variable, replace the default -Xmx2048m with the following:

   -Xmx4096m -XX:PermSize=128m -XX:MaxPermSize=128m

3. Restart Ambari Server for this change to take effect.

   ambari-server restart
