REM By default the script will use JAVA_HOME to determine which java
REM to use, but you can set a specific path for Solr to use without
REM affecting other Java applications on your server/workstation.
REM set SOLR_JAVA_HOME=

REM Increase Java Min/Max Heap as needed to support your indexing / query needs
set SOLR_JAVA_MEM=-Xms512m -Xmx512m

REM Enable verbose GC logging
set GC_LOG_OPTS=-verbose:gc -XX:+PrintHeapAtGC -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps -XX:+PrintTenuringDistribution -XX:+PrintGCApplicationStoppedTime

REM These GC settings have shown to work well for a number of common Solr workloads
set GC_TUNE=-XX:NewRatio=3 ^
 -XX:SurvivorRatio=4 ^
 -XX:TargetSurvivorRatio=90 ^
 -XX:MaxTenuringThreshold=8 ^
 -XX:+UseConcMarkSweepGC ^
 -XX:+UseParNewGC ^
 -XX:ConcGCThreads=4 -XX:ParallelGCThreads=4 ^
 -XX:+CMSScavengeBeforeRemark ^
 -XX:PretenureSizeThreshold=64m ^
 -XX:+UseCMSInitiatingOccupancyOnly ^
 -XX:CMSInitiatingOccupancyFraction=50 ^
 -XX:CMSMaxAbortablePrecleanTime=6000 ^
 -XX:+CMSParallelRemarkEnabled ^

REM Set the ZooKeeper connection string if using an external ZooKeeper ensemble
REM e.g. host1:2181,host2:2181/chroot
REM Leave empty if not using SolrCloud
REM set ZK_HOST=

REM Set the ZooKeeper client timeout (for SolrCloud mode)
REM set ZK_CLIENT_TIMEOUT=15000

REM By default the start script uses "localhost"; override the hostname here
REM for production SolrCloud environments to control the hostname exposed to cluster state
REM set SOLR_HOST=192.168.1.1

REM By default the start script uses UTC; override the timezone if needed
REM set SOLR_TIMEZONE=UTC

REM By default the start script enables some RMI related parameters to allow attaching
REM JMX savvy tools like VisualVM remotely, set to "false" to disable that behavior
REM (recommended in production environments)
set ENABLE_REMOTE_JMX_OPTS=true

REM Anything you add to the SOLR_OPTS variable will be included in the java
REM start command line as-is, in ADDITION to other options. If you specify the
REM -a option on start script, those options will be appended as well. Examples:
REM set SOLR_OPTS=%SOLR_OPTS% -Dsolr.autoSoftCommit.maxTime=3000
REM set SOLR_OPTS=%SOLR_OPTS% -Dsolr.autoCommit.maxTime=60000
REM set SOLR_OPTS=%SOLR_OPTS% -Dsolr.clustering.enabled=true
