Configure Java Virtual Machines

To configure a Java Virtual Machine (JVM), set Java options by using the JAVA_OPTS environment variable.

You can set the Java options in the following file:

On UNIX.

JBoss installation directory

>/bin/standalone.conf

On Windows.

JBoss installation directory

>\bin\standalone.conf.bat

The following table describes the Java options settings:

Java Options	Description
-server	Results in a slower startup but subsequent operations are faster.
-De360.mdm.host -De360.mdm.port	Application server host and port. If you want to deploy the MDM Hub applications on a JBoss port other than 4447, set the following Java options: -De360.mdm.host . Set to the IP address of the JBoss host. -De360.mdm.port . Set to the JBoss remote port configured in place of 4447. If your environment uses the HTTPS communication protocol and the security certificate is issued to a Fully Qualified Domain Name (FQDN), set the hostname to the FQDN displayed in the security certificate. If you do not configure this parameter, Informatica Data Director screens based on the Entity 360 Framework might not work as expected.
-De360.connection.channel	Specifies the communication protocol the Entity 360 application uses to communicate with the MDM Hub Server. Specify whether the communication protocol to use is EJB, HTTP or HTTPS. Default is -De360.connection.channel=http . Ensure you set the supporting application server host property -De360.mdm.host and application server port property -De360.mdm.port to the default values.
-Didd.mdm.port	Required if you want to deploy Data Director with subject areas using a non-default HTTP or HTTPS listener port. The property is used for deploying the subject area application during server initialization. Specifies the HTTP or HTTPS listener port used by the JVM for the applications. Default is 8080 .
-Didd.protocol	Required if you want to deploy Data Director with subject areas. The property is used for deploying the subject area application during server initialization. Specifies whether the communication protocol to use is HTTP or HTTPS. Default is HTTP .
-Ddb2.jcc.charsetDecoderEncoder	Required to use the MDM Hub Sample Operational Reference Store. Enables the JDBC driver to return the Unicode replacement character (U+FFFD) in place of a sequence of bytes that is not a UTF-8 string. Set to 3 .
-Djava.net.preferIPv4Stack	Specifies whether Java uses Internet Protocol version 4 (IPv4). If the operating system uses Internet Protocol version 6 (IPv6), set to true .
-Djboss.as.management.blocking.timeout	Time in seconds to wait for JBoss to deploy. To ensure that JBoss does not fail to start, you can set the value to 5000 . Adjust the time period based on your environment. Default is 300 . If you do not configure the parameter, you might encounter a JBoss deployment timeout.
-Djgroups.bind_addr	Interface on which JGroup must receive and send messages. Required in multinode or cluster environments. Ensure that each node binds to its own network interface.
-DFrameworksLogConfigurationPath	Path to the log4j.xml file.
-Dmdm.node.groupid	Specifies a group ID for Java Virtual Machines in the MDM Hub implementation. Required only if you want logical groupings of Hub Servers and Process Servers.
-Dmdm.ps.zk.node	Required if you want to use smart search with Solr. Set this Java option on the JVM for the Process Server that is intended to be the ZooKeeper server. Set to true .
-Dmdm.ps.search.node	Required if you want to use smart search with Solr. Set this Java option on the JVMs for the Process Servers that will have search processing enabled and function as Solr servers. Set it to true .
-Dsearch.service.port	Required if you want to use smart search with Solr. Required if you want to install multiple Process Servers on the same machine but on different JVMs and enable smart search on all the Process Servers on the machine. This Java option specifies the port used by the JVM for the search service. To avoid port conflicts, use the default port for the JVM of one Process Server, and set this Java option to the relevant port numbers for the JVMs of the remaining Process Servers.
-Dfile.encoding -Dorg.apache.catalina.connector.URI_ENCODING	Required if you want to use Informatica Data Director and use REST APIs to search for records. Set both the Java options to UTF-8 to ensure that you can find and save records that contain UTF-8 characters.
-Dorg.apache.coyote.http11.Http11Protocol.MAX_HEADER_SIZE	Maximum size of the HTTP headers, in bytes. The smart search requests might fail if the header size is low. Set to 16384 .
-Dtask.pageSize=<maximum number of tasks>	Specifies the maximum number of ActiveVOS tasks that are retrieved for each request. Default is 5000 . Increase the number if your environment has a large number of tasks.
-Dstricttransportsecurity.flag	Specifies whether web browsers must convert all attempts to access Data Director using the HTTP requests to the HTTPS requests instead. Set to true .
-Xms	Initial heap size. Set to 2048m .
-Xmx	Maximum JVM heap size. Set to 4 GB or higher. For example, to set the -Xmx to 4096m , use the following JAVA_OPTIONS environment variable setting: set "JAVA_OPTIONS=-server ... -Xmx4096m"
XX:+UseCodeCacheFlushing	Specifies whether the JVM disposes of compiled code when the code cache is full.
-XX:ReservedCodeCacheSize	JIT code cache size. To enhance the performance of the MDM Hub environment, set to 512m .
-XX:MaxMetaspaceSize	Maximum metaspace size. To prevent the JVM from running out of memory, set to 1G .
