Haddii aad la kulmeyso arrimaha waxqabadka Tomcat , sababta caadiga ah waa la'aanta JVM ( Mashiinka Virtual Machine^{(Java Virtual Machine)} ) qoondaynta xusuusta. Meesha ugu sarraysa ee cabbirka ugu badnaan waa 64MB ama 128MB. Waxaad kordhin kartaa cabbirka ugu badan ee codsiyada adiga oo dejinaya cabbirka -Xmx^(-Xmx) JVM.

Tusaale ahaan,  -Xmx512m waxa^(-Xmx512m) ay ogolanaysaa ugu badnaan 512MB tuulo in loo qoondeeyo JVM . Si aad u hagaajiso cabbirkan, midig guji sumadda Kumbuyuutarkayga^{(My Computer)} , ka dibna dooro tab Advanced . Guji badhanka Isbedelka Deegaanka :^{(Environment Variables)}

Samee doorsoomiyaha CATALINA_OPTS , oo deji qiimaha la rabo, tusaale ahaan " -server -Xmx256m ".

Haddii aad ku shaqeyso Linux ama UNIX , aad terminalka oo isticmaal akoontada tomcat adiga oo isticmaalaya sudo su –tomcat ama magac akoon oo u dhigma iyadoo ku xiran habkaaga. Waa inaad isticmaashaa akoonka loo isticmaalo socodsiinta Tomcat .

Hubi labada CATALINA_OPTS iyo JAVA_OPTS doorsoomayaasha deegaanka. U deji doorsoomayaasha deegaanka qiime sare. Tusaale ahaan, haddii doorsoomaha JAVA_OPTS uu ka kooban yahay ugu yaraan 64MB iyo 128MB cabbirka ugu sarreeya, u kordhi 128MB iyo 256MB qiimayaal.

OLD: JAVA_OPTS="-Xms64m -Xmx128m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"

OLD: JAVA_OPTS="-Xms128m -Xmx256m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"

Hubi^(Make) inaad isticmaasho qiimaha ugu badan oo ka yar cabbirka RAM-kaaga jireed, haddii kale waxaa lagu dhejin doonaa disk-ga adag, taas oo keeni karta arrimo badan oo waxqabad ah.

Si aad u hubiso in goobaha cusub ay hirgelayaan, aad URL -ka server-kaaga Tomcat ka bacdina guji Status :

Waa inaad ku aragto qiime cusub hoosta qaybta JVM :

Haddii aadan ku arkin xusuusta JVM ee la cusboonaysiiyay ee bogga, isku day inaad dib u bilowdo Tomcat maadaama isbeddellada cabbirku ay u baahan yihiin Tomcat dib u bilaabo ka hor intaysan dhaqan gelin. Tani waa inay hagaajisaa arrimahaaga waxqabadka liita ee Tomcat iyo sidoo kale ka fogow dhibaatooyinka xusuusta ee qoraallada dhinaca serverka. Haddii aad su'aalo qabto, noogu soo sheeg faallooyinka. Ku raaxayso!

How to Increase Tomcat’s Memory Allocation

If yоu are experiencing performance issues with Τomcat, a сommon caυse is the lack of JVM (Java Virtual Machine) memory allocation. The default setting of the maximum heap size is 64MB or 128MB. Υou can increase the maximum heap size of applications by settіng the -Xmx JVM parameter.

For example, -Xmx512m allows maximum 512MB heap to be allocated for the JVM. To adjust this parameter, right click the My Computer icon, then choose the Advanced tab. Click the Environment Variables button:

Create the CATALINA_OPTS variable, and set the desired value, for example “-server -Xmx256m“.

If you are running on Linux or UNIX, go to the terminal and use the tomcat account by using sudo su – tomcat or a corresponding account name depending on your setup.  You should use the account that is used to run Tomcat.

Check both CATALINA_OPTS and JAVA_OPTS environment variables.  Set the environment variables to a higher value. For example, if the JAVA_OPTS variable is containing a minimum of 64MB and 128MB maximum heap size, increase it to 128MB and 256MB values.

OLD: JAVA_OPTS="-Xms64m -Xmx128m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"

OLD: JAVA_OPTS="-Xms128m -Xmx256m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"

Make sure to use a maximum value that is less than your physical RAM’s size, otherwise it will be paged to the hard disk, which could cause more performance issues.

To check if the new settings are in effect, go to the URL of your Tomcat server and then click Status:

You should see a new value under the JVM section:

If you did not see an updated JVM memory on the page, try restarting Tomcat as parameter changes need a Tomcat restart before taking effect. This should fix your issues on poor Tomcat performance and also avoid out of memory problems with your server side scripts. If you have questions, let us know in the comments. Enjoy!
