server's total available ram..

[PoRnosJH]

i have this machine : Xeon E5504 - 12gb DDR3 Ram - 140gb 10k SAS x2(raid 0 = 280 gb HDD)

 

i want to know if my l2j server can run on all ram(12gb) or atleast to 10gb ram...

i have to do some edits?and if yes where?

or if i dont...if your windows allow you more than 12gb ram (to my situtation i have Windows Server Enterprise 32bit and gives up to 64gb ram)im ok??my server will take all the available ram if ll needs to??

 

and last..what the reason for -xmx -xms -xmn on StartgameServer.bat (edit)??only for carbage collector-lagg??or there is something to do with the max amount of ram my server can run on...

 

ty for your time..i m w8 for your help!!

Because you have 12 gb ram this doesnt mean that your server will use the 100% of it. It just use only the part that it need.

[PoRnosJH]

ofc..but i dont asked that..i asked if he needs to run on 10gb ram he will?..for example..if he ll needs to uses 5gb ram he will??or i got to do any edit to gameserver.bat or in my windows or i dont even know...(or to install something addon windows)

 

and like i asked ...

 

and last..what the reason for -xmx -xms -xmn on StartgameServer.bat (edit)??only for carbage collector-lagg??or there is something to do with the max amount of ram my server can run on...

 

ty for your help..extremedwarf and i already learn a lot from your guides-comments..but plz try to help me little more here...

 

im still w8 for your help guys...i want to fully understand this...ty

with windows 32x you cant set more then 1 GB ram for usage... install 64x and use your ram :P

with windows 32x you cant set more then 1 GB ram for usage... install 64x and use your ram :P

it's 3.25.

Who says that o0 ?

[PoRnosJH]

kuba you have a way to use 10gb ram for l2 on Windows Server Enterprise x32???

 

if yes plz can you tell it to me too....(on microsoft's page i find that my version is up to 64gb ram..but i cant put more than -1580xmx -1580xms. . . . ..(i have 12gb ramm). . ..

[kuba90]

xmx is the maximum heap size in the JVM.

xms is the initial heap size in the JVM.

 

Ill give you an example to understand how to use those values. Lets say you give 1 GB maximum heap size. When the server starts, it doesnt use all that memory, it doesnt need to. After many players login, or server is up for a long time ( memory leaks but dont pay attention to that ) memory starts getting filled up. If memory gets filled up to 1 GB / 1 GB then when JVM tries to allocate a new object it doesnt find any space to do that. So the garbage collector , starts "scanning" whole heap which adds load to the server making it not able to respond easily and in reasonable time. He does that so as he can collect garbages to free some space.

 

Usually in server applications you use xmx = xms , the same value. And that value is limmited by your adressing model or by your rams maximum. But, you shouldnt use ALL your ram in the JVM, cause free ram is needed for "other" things. Based on what you say:

 

but i cant put more than -1580xmx -1580xms.

 

How did you figure that out ?

well to be honest if you dont have that much knowledge your server will never ever going to use that much memory hence you dont need to worry about this 1,5gb ram is enough for 100-120 player(ofc depends on the pack too but in general)

[PoRnosJH]

i got 12gb ram ..i m thinking to put about -xmx8600 -xms8600 ... i tried to put -xmx3200 -xms 3200 ..

 

and my bat dont starts... now im trying to put x64 windows... and then i ll try again...

 

8-9gb for server and 3 gb for the rest machine isnt nice idea to your opinion..?

you really dont have absolutely 0 knowledge so to speak...

 

1st the maximum heap size JVM can initialize under 32bit is 1,5gb hence to setup more you need 64bit...

2nd you dont need 8-9gb and 3gb for the rest you never going to use that much memory(to comparison 2000player on an l2j server = pc with 16gb memory with usual optimalizations)

3rd dont use the same amount of maximum heap size and initial heap size use google to find out what value is for what...

[kuba90]

He is asking, he didnt suggested anything .... chill out.

 

1st the maximum heap size JVM can initialize under 32bit is 1,5gb hence to setup more you need 64bit...

 

The maximum heap size JVM can initialize under 32 bit is 4 GB ( do the maths ) , just some OS limmit it to 3 GB, some others to even less ( 1GB etc ).

 

2nd you dont need 8-9gb and 3gb for the rest you never going to use that much memory(to comparison 2000player on an l2j server = pc with 16gb memory with usual optimalizations)

 

Thats true, you wont need that much memory. You can run fine with 4GB with 800 players ( tested ).

 

3rd dont use the same amount of maximum heap size and initial heap size use google to find out what value is for what...

 

Wrong. If you allocate a small initial heap size ( xms ) then the JVM will reallocate ( increase/decrease ) the heap size each time its filled. For example, when it reaches initial xms ( 1GB ) it will reallocate more ( if xmx > xms ) which will add additional CPU overhead. For server applications, the best practice is to use xms = xmx. And always start with a quite sufficient xms ( eg 4 GB ) so as you wont need memory reallocation.

asking is one thing using google is another thing...and no its not wrong since again...the allocated memory always depends on how big server you have and since 100-120player server run fine with 512mb allocation on boot and only 1gb maximum heap size than whats the point of 1st a pc like and 2nd such a big heap...

 

+ still 32bit is stupid under a server pc(same stupidity as windows under server pc)

 

about the heap size(depends on OS since i test at home on win xp 32bit for me its 1,5gb just like for him)and on server pc who cares i use 64bit anyway...

 

also for the allocation i would prefere a bigger mysql heap size and if the server pc run the website too than watch for the apache server too since mysql and apache are the vulnerable parts...

[kuba90]

What exactly is apache doing in the gameserver machine o0 ?  :P

[JustMyStyle]

What exactly is apache doing in the gameserver machine o0 ?  :P

 

many ppl(most ppl) run their server website on the same pc where the server runs

[kuba90]

Know that, just making fun of it  ;D
