Examples with InternalDistributedSystem org.apache.geode.distributed.internal.InternalDistributedSystem used on opensource projects

Example 1 with InternalDistributedSystem

use of org.apache.geode.distributed.internal.InternalDistributedSystem in project geode by apache.

the class AdminDistributedSystemFactory method defineDistributedSystem.

/**
   * Defines a distributed system configuration for administering the distributed system to which
   * this VM is currently connected. The <code>DistributedSystem</code> is used to configure the
   * discovery mechanism (multicast or locators), bind address, SSL attributes, as well as the
   * logger of the <code>DistributedSystemConfig</code>. Note that the distributed system will not
   * be able to be administered until the {@link AdminDistributedSystem#connect connect} method is
   * invoked.
   *
   * @param system A connection to the distributed system
   * @param remoteCommand The shell command that is used to launch processes that run on remote
   *        machines. If <code>null</code>, then the
   *        {@linkplain DistributedSystemConfig#DEFAULT_REMOTE_COMMAND default} will be used.
   *
   * @since GemFire 4.0

Example 2 with InternalDistributedSystem

use of org.apache.geode.distributed.internal.InternalDistributedSystem in project geode by apache.

the class GemFireMemberStatus method initializePeers.

Example 3 with InternalDistributedSystem

use of org.apache.geode.distributed.internal.InternalDistributedSystem in project geode by apache.

the class DistributedSystem method connect.

//////////////////////// Static Methods ////////////////////////
/**
   * Connects to a GemFire distributed system with a configuration supplemented by the given
   * properties. See {@linkplain ConfigurationProperties} for available GemFire properties and their
   * meanings.
   * <P>
   * The actual configuration attribute values used to connect comes from the following sources:
   * <OL>
   * <LI>System properties. If a system property named "<code>gemfire.</code><em>propertyName</em>"
   * is defined and its value is not an empty string then its value will be used for the named
   * configuration attribute.
   *
   * <LI>Code properties. Otherwise if a property is defined in the <code>config</code> parameter
   * object and its value is not an empty string then its value will be used for that configuration
   * attribute.
   * <LI>File properties. Otherwise if a property is defined in a configuration property file found
   * by this application and its value is not an empty string then its value will be used for that
   * configuration attribute. A configuration property file may not exist. See the following section
   * for how configuration property files are found.
   * <LI>Defaults. Otherwise a default value is used.
   * </OL>
   * <P>
   * The name of the property file can be specified using the "gemfirePropertyFile" system property.
   * If the system property is set to a relative file name then it is searched for in following
   * locations. If the system property is set to an absolute file name then that file is used as the
   * property file. If the system property is not set, then the name of the property file defaults
   * to "gemfire.properties". The configuration file is searched for in the following locations:
   *
   * <OL>
   * <LI>Current directory (directory in which the VM was launched)</LI>
   * <LI>User's home directory</LI>
   * <LI>Class path (loaded as a {@linkplain ClassLoader#getResource(String) system resource})</LI>
   * </OL>
   *
   * If the configuration file cannot be located, then the property will have its default value as
   * described <a href="#configuration">above</a>.
   *
   * @param config The <a href="#configuration">configuration properties</a> used when connecting to
   *        the distributed system
   *
   * @throws IllegalArgumentException If <code>config</code> contains an unknown configuration
   *         property or a configuration property does not have an allowed value. Note that the
   *         values of boolean properties are parsed using
   *         {@link Boolean#valueOf(java.lang.String)}. Therefore all values other than "true"
   *         values will be considered <code>false</code> -- an exception will not be thrown.
   * @throws IllegalStateException If a <code>DistributedSystem</code> with a different
   *         configuration has already been created in this VM or if this VM is
   *         {@link org.apache.geode.admin.AdminDistributedSystem administering} a distributed
   *         system.
   * @throws org.apache.geode.GemFireIOException Problems while reading configuration properties
   *         file or while opening the log file.
   * @throws org.apache.geode.GemFireConfigException The distribution transport is not configured
   *         correctly
   *
   * @deprecated as of 6.5 use {@link CacheFactory#create} or {@link ClientCacheFactory#create}
   *             instead.
