How To Growth Heap Retentiveness Of Apache Tomcat Server
Increasing Heap size of Tomcat
You tin increment heap size of Tomcat past times setting JAVA_OPTS or CATALINA_OPTS at the move past times of the catalina.sh, file if you lot are running Tomcat inwards Linux together with past times putting JAVA_OPTS or CATALINA_OPTS into the catalina.bat file if you lot are running Tomcat inwards Windows. This approach volition run irrespective of tomcat version i.e. you lot tin increment the heap retention of tomcat 5.5, tomcat 6, tomcat vii together with fifty-fifty tomcat 8 past times using this technique. You tin discovery the catalina.sh together with catalina.bat file inwards the bin directory of tomcat installation folder e.g. inwards my automobile catalina.sh together with the catalina.bat file is located nether C:\Program Files\Apache Software Foundation\Apache Tomcat 7.0.41\bin directory. If you lot opened upwardly the catalina.bat belongings you lot volition encounter the advice given past times Tomcat creator itself on how to give additional JVM options to Tomcat process.
When you lot increment heap retention past times setting JAVA_OPTS pick every bit shown below. Don't worry that it volition non override whatsoever previous JVM options, all the places a novel value is fix they ensure that it is appending to the existing values.
Btw, I prefer setting it inwards the startup.sh instead of catalina.sh. Setting it inwards catalina.sh would apply to the procedure started past times shutdown ascendancy every bit well, which may non hold upwardly necessary.
Go to catalina .bat together with fix this
set CATALINA_OPTS=-Xms1024m -Xmx2048m;
or
set JAVA_OPTS=-Xms2048m -Xmx2048m;
The higher upwardly ascendancy volition increment the heap size of tomcat to 2GB for both startup together with maximum memory.
export CATALINA_OPTS=-Xms1023m -Xmx2048m;
-Xms – is the minimum or initial size of your heap
-Xmx – is the maximum size
or
export JAVA_OPTS=”-Xms1024m -Xmx1024m”
On Linux, you lot tin every bit good fix inwards the startup.sh file which is every bit good available inwards the same bin folder.
Note that CATALINA_OPTS is a amend house than JAVA_OPTS for putting JVM heap retention settings. The onetime is solely used when genuinely starting the Tomcat instance. JAVA_OPTS is every bit good used to kickoff JVMs that solely interact alongside Tomcat (for representative the JVM representative that is used to transportation the shutdown message to a running Tomcat instance).
If you lot opened upwardly the catalina.bat or catalina.sh file, you lot volition encounter this approach is recommended past times Tomcat itself:
One to a greater extent than payoff of this approach is that it doesn't affair whether you lot are running Tomcat inwards Eclipse or NetBeans, this approach volition run inwards all status because fifty-fifty IDEs volition telephone phone these scripts to kickoff the Tomcat inwards the respective operating system.
Btw, If your Tomcat is constantly going downward alongside java.lang.OutOfMemoryError: Java Heap space together with hence it mightiness hold upwardly the fourth dimension to motility to 64-bit JVM together with increasing heap size of Tomcat. Since Tomcat is every bit good a Java process, you lot tin increment Tomcat's heap size only similar whatsoever other Java application e.g. past times using -Xmx option.
The 64-bit JVM allows you lot to fix fifty-fifty larger heap retention e.g. 8 to 10GB to cater the necessitate of bigger Java spider web application which holds millions of user records. On the other hand, 32-bit JVM theoretically allows 4GB of the heap but practically it fifty-fifty lesser than that. See here for to a greater extent than details on maximum heap retention available on 32-bit together with 64-bit Java virtual machines.

You tin increment heap size of Tomcat past times setting JAVA_OPTS or CATALINA_OPTS at the move past times of the catalina.sh, file if you lot are running Tomcat inwards Linux together with past times putting JAVA_OPTS or CATALINA_OPTS into the catalina.bat file if you lot are running Tomcat inwards Windows.

Btw, I prefer setting it inwards the startup.sh instead of catalina.sh. Setting it inwards catalina.sh would apply to the procedure started past times shutdown ascendancy every bit well, which may non hold upwardly necessary.
Steps to increment heap size inwards Tomcat on Windows:
Go to catalina .bat together with fix this
set CATALINA_OPTS=-Xms1024m -Xmx2048m;
or
set JAVA_OPTS=-Xms2048m -Xmx2048m;
The higher upwardly ascendancy volition increment the heap size of tomcat to 2GB for both startup together with maximum memory.
Steps to increment heap size inwards Tomcat on Linux:
export CATALINA_OPTS=-Xms1023m -Xmx2048m;
-Xms – is the minimum or initial size of your heap
-Xmx – is the maximum size
or
export JAVA_OPTS=”-Xms1024m -Xmx1024m”
On Linux, you lot tin every bit good fix inwards the startup.sh file which is every bit good available inwards the same bin folder.

JAVA_OPTS is every bit good used to kickoff JVMs that solely interact alongside Tomcat (for representative the JVM representative that is used to transportation the shutdown message to a running Tomcat instance).
If you lot opened upwardly the catalina.bat or catalina.sh file, you lot volition encounter this approach is recommended past times Tomcat itself:
rem CATALINA_OPTS (Optional) Java runtime options used when the "start",and
rem "run" or "debug" ascendancy is executed.
rem Include hither together with non inwards JAVA_OPTS all options, that should
rem solely hold upwardly used past times Tomcat itself, non past times the halt process,
rem the version ascendancy etc.
rem Examples are heap size, GC logging, JMX ports etc.
rem JAVA_OPTS (Optional) Java runtime options used when whatsoever command
rem is executed.
rem Include hither together with non inwards CATALINA_OPTS all options, that
rem should hold upwardly used past times Tomcat together with every bit good past times the halt process,
rem the version ascendancy etc.
rem Most options should larn into CATALINA_OPTS.
One to a greater extent than payoff of this approach is that it doesn't affair whether you lot are running Tomcat inwards Eclipse or NetBeans, this approach volition run inwards all status because fifty-fifty IDEs volition telephone phone these scripts to kickoff the Tomcat inwards the respective operating system.
