#Dbeaver java heap space portable
On the Connection properties tab page, right-click and select Add new property. First I was using the portable version of dbeaver.
Click Add File and select the obtained JDBC file obtained in 1.d. URL format: jdbc:presto:// IP address of node 1 where the ZooKeeper service resides:2181, IP address of node 2 where the ZooKeeper service resides:2181, IP address of node 3 where the ZooKeeper service resides:2181/hive/default?serviceDiscoveryMode=zooKeeper&zooKeeperNamespace=hsbroker&zooKeeperServerPrincipal=zookeeper/Įxample: jdbc:presto://192.168.8.37:2181 ,192.168.8.38:2181 ,192.168.8.39:2181 /hive/default?serviceDiscoveryMode=zooKeeper&zooKeeperNamespace=hsbroker&zooKeeperServerPrincipal=zookeeper/ 
Enter the URL of HetuEngine in the URL Template text box. Search for Presto in the search box and double-click the Presto icon. Start the DBeaver, right-click Database Navigator, and click Create New Connection. The heap space is created by the JVM when it starts. New objects are always created in the heap space, and references to these objects are stored in the stack memory. Heap space is used for the dynamic memory allocation of Java objects and classes at runtime. setRedraw(Control.java:3664) at .controls.resultset. Whenever new variables and objects are declared, new methods are called or other similar operations are performed, the JVM designates memory to these operations from either the Stack Memory or Heap Space. If DBeaver is started, restart the DBeaver software for the new configuration items in the dbeaver.ini file to take effect. When I use Refresh every 3 seconds for automated query, heap memory usage is. If the current time zone is GMT+, add -Duser.timezone=UTC to the dbeaver.ini file to change the time zone to UTC. The Greenwich Mean Time (GMT) is not supported.
