# Settings here will override settings in existing env vars or in bin/solr.  The default shipped state
# of this file is completely commented.

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

# This controls the number of seconds that the solr script will wait for
# Solr to stop gracefully or Solr to start.  If the graceful stop fails,
# the script will forcibly stop Solr.  If the start fails, the script will
# give up waiting and display the last few lines of the logfile.
#SOLR_STOP_WAIT="180"

# Increase Java Heap as needed to support your indexing / query needs
#SOLR_HEAP="512m"

# Expert: If you want finer control over memory options, specify them directly
# Comment out SOLR_HEAP if you are using this though, that takes precedence
#SOLR_JAVA_MEM="-Xms512m -Xmx512m"

# Enable verbose GC logging...
#  * If this is unset, various default options will be selected depending on which JVM version is in use
#  * For Java 8: if this is set, additional params will be added to specify the log file & rotation
#  * For Java 9 or higher: each included opt param that starts with '-Xlog:gc', but does not include an
#    output specifier, will have a 'file' output specifier (as well as formatting & rollover options)
#    appended, using the effective value of the SOLR_LOGS_DIR.

# By default the start script uses UTC; override the timezone if needed
#SOLR_TIMEZONE="UTC"
