How to change java.io.tmpdir in system properties

[chung_yonge1684]

Hello Everypne,

In order to change the java.io.tmpdir to 'C:\Adobe\AEM\Author\cq-temp', I changed like the below that  in C:\Adobe\AEM\Author\crx-quickstart\bin\start.bat

::* -------------------

::* Default JVM options

::* -------------------

set CQ_JVM_OPTS=-server

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -Djava.awt.headless=true

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -Xms8192m

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -Xmx8192m

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -XX:MaxMetaspaceSize=512m

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -XX:NewRatio=1

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -XX:MaxTenuringThreshold=15

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -XX:+UseConcMarkSweepGC

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -XX:ConcGCThreads=4

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -XX:ParallelGCThreads=4

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -Djava.io.tmpdir=C:\Adobe\AEM\Author\cq-temp

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -XX:+HeapDumpOnOutOfMemoryError

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -XX:HeapDumpPath=C:\Adobe\AEM\Author\cq-temp

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -Doak.queryLimitInMemory=500000

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -Doak.queryLimitReads=100000

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -Dupdate.limit=250000

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -Doak.fastQuerySize=true

But it doesn't  change.

My environment is the following :

-AEM 6.3

-Windows 10

-Java 1.8.1

Can you help me with mine?

Regards

Chung Yong.

When I upload the package file, java.lang.OutOfMemoryError : Java heap space happens.

I want to fix java.lang.OutOfMemoryError : Java heap space.

[arunpatidar]

You may need to increase heap memory

e.g.

-Xmx

The flag Xmx specifies the maximum memory allocation pool for a Java Virtual Machine (JVM), while Xms specifies the initial memory allocation pool. A common use for these flags is when you encounter a java.lang.OutOfMemoryError.

-Xms        set initial Java heap size

-Xmx        set maximum Java heap size

-Xss        set java thread stack size

[Jörg_Hoh]

Have you restarted your instance?

[chung_yonge1684]

Yes, I have restared instance.

[Jörg_Hoh]

"GC overhead limit excessed" means that you ran out of heap memory, not disk memory :-)

[chung_yonge1684]

I have imported package1.zip successfully in Package Manager.

but we could not import contenct2.zip because of GC overhead limit exceeded

--------------------------------------------

package1.zip       : 20 MB

cotent2.zip          : 723 MB

Here is my JVM options.

set CQ_JVM_OPTS=-server

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -Djava.awt.headless=true

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -XX:NewRatio=1

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -XX:+UseParallelGC

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -XX:+UseParallelOldGC

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -XX:ParallelGCThreads=4

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -Xms8192m

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -Xmx8192m

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -XX:PermSize=256m

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -XX:MaxPermSize=1024m

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -Djava.io.tmpdir=C:\Adobe\AEM\Author\cq-temp

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -XX:+HeapDumpOnOutOfMemoryError

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -XX:HeapDumpPath=C:\Adobe\AEM\Author\cq-temp

set CQ_JVM_OPTS=%CQ_JVM_OPTS% -Djackrabbit.maxQueuedEvents=1000000

My environment is the following :

-AEM 6.3

-Windows 10

-RAM 8 GM.

-Java 1.8.1

[smacdonald2008]

Do you have another instance to test with. As Joerg as pointed out, looks like memory issue with your server.

[chung_yonge1684]

My friend has the same environment with me.

-AEM 6.3

-Windows 10

-RAM 8 GM.

-Java 1.8.1

he has the same error(GC overhead limit exceeded)  with me.

Do we have to replace the ram size from 8 G to 16 G in order to fix the memory issue ?

[smacdonald2008]

that would be a good way to start. 8 GB of Ram is not a lot of RAM for an enterprise server. However 8 is within specification of AEM Technical Requirements

[Jörg_Hoh]

Adding more RAM to the machine itself does not solve the problem in the first place, you need to give the JVM more heap. In my local development environments I always used -Xmx1G and it worked flawlessly.

What kind of package do you install?

Jörg

[chung_yonge1684]

This is my CQ_JVM_OPTS.

CQ_JVM_OPTS='-server -Xms4096m -Xmx4096m  -Xss1024k  -XX:MaxPermSize=512m  -XX:-UseGCOverheadLimit -Djava.awt.headless=true -Djava.io.tmpdir=C:\Adobe\AEM\Author\cq-temp'

When I upload cotent2.zip(723 MB) into Package Manager,  GC overhead limit exceeded happens.

This is my system.

This is my Task Manager.

[wasil_z]

In case if you are not starting the instance using <crx-quickstart>\bin\start.bat,  please do. It seems you are starting by double-clicking on the jar file.

Thanks

Wasil

[chung_yonge1684]

Yes, I was starting by double-clicking on the jar file.

Can you explain how to run start.bat in command.

I referenced the following url.

Command Line Start and Stop

But I can not run start.bat

[wasil_z]

In Windows explorer, just execute the start.bat by double clicking it. I assume java is set on the path environment variable already[1].

It would launch the AEM instance in new CMD shell as follows :

Thanks

P.S. : Stop existing running AEM instance to avoid any port conflict while startup.

[smacdonald2008]

Our Cust Care team suggested:

There is a powershell script they can run on their windows environment to capture thread dumps and windows process information (similar to top)

https://github.com/cqsupport/jstackSeries.sh/blob/master/jstackSeries_powershell.ps1

CPU utilization would be high here as GC would be throttling the instance

That -xss JVM flag seems … out of place.  It limits the thread stack to 1 MB which is tiny .

That MaxPermSize flag is also useless if they are on Java8.

[chung_yonge1684]

I have already added JAVA_HOME in Environment Varialble for System.

But I can not start start.bat in Windows PowerShell too.

This is my start.bat

You could be facing a bug of some sort. Customer care and AEM community members have attempted to answer this. If you are still facing issues, i recommend opening a support ticket so our cust care team can investigate this and get to the bottom of what is happening.

[chung_yonge1684]

I fixed the error.

CQ_JVM_OPTS In start.bat changed like the below that.

if not defined CQ_JVM_OPTS set CQ_JVM_OPTS=-Xms8192m -Xmx8192m -Xss1024k -XX:MaxPermSize=1024m -XX:-UseGCOverheadLimit -Djava.awt.headless=true -Djava.io.tmpdir=C:\Adobe\AEM\Author\cq-temp

Thank you.
