netweaver AS java not stating

[nelson_chamba2]

Dear all,

I´m having problem starting my AS Java, as the screenshot shows. It says starting but it´s not changing is status.

The error message is 503 Service Unavailable.

On the console I can see that the disk+work.exe did not started completely.

any idea please?

Best regards,

The problem is pretty understandable.

You only have 8 GB of memory and there is Database, ABAP, Java and SMD running.

For sure the system is undersized.

If possible consider adding more memory to the server.

The only thing I can suggest is to reduce the heap memory for the Java server node from 2 GB to 1GB. For that you need to change the -Xmx and -Xms to value 1024 and restart the Java stack.

This is something not which is not recommended according to the SAP note.

1603093  - SAP JVM 4.1 parameters NetWeaver 2004 and 7.0

There is not need to run Jcmon. You need to select the "AS Java Process table" in the SAP MMC to see the status of the J2EE processes.

Sharman,

the link is great but all my settings looking good or according with the recommended and I still don´t know why this is not running.

It was running perfect since the license problems. it was running with a temp license and it expired and I lost connections till i request a new one that gave me problems because of the product choose. so I had to chose a new product that was Standard Java and not the J2EE.

Now i don´t know if that was the problem

Please advise.

Hi,

Could you please paste the output of JCMON in your command prompt.

Use the below comand in your system:-

login with sidadm and open cmd:-

jcmon pf=/usr/sap/<SID>/sys/profile/<SAPSID>_<INSTANCE_ID>_<HOST>

Hi all,

SAP Support team is suggesting this

(1) Please check if OS reboot could resolve your problem.

(2) If not, please shutdown NetWeaver Java (leave ABAP running),

  and make sure there's enough physical memory (at very least 3GB).

(3) You can launch configtool and assign 1.5GB max heap size AND xms

for server node and restart AS Java, and see if it could be started.

My question is how do I do the step (2)?

Best regards,

(1) Please check if OS reboot could resolve your problem.

You already tried this.

(2) If not, please shutdown NetWeaver Java (leave ABAP running), and make sure there's enough physical memory (at very least 3GB).

Tx SMICM

(3) You can launch configtool and assign 1.5GB max heap size AND xms for server node and restart AS Java, and see if it could be started.

Check my suggestion in the last reply.

Hi Marius,

this is not what your are expecting to see???

[former_member206552]

Hi Nelson,

no not if you are trying to access jcmon

then you need to execute

jcmon pf=\\SAP1\sapmnt\SLM\profile\SLM_DVEBMGS00_SAP1

from command line.

But please follow the recommendations of Reagan, and let us know the results

Hi Nelson,

What is the reason for the restart ?

Reason for asking is when we load packages it takes sometime up to an hour for java to start the first time

As requested please upload the logs

Hi Marius,

Look my heap size is 256 how big should I set it to?

My servers is running Windows 2008 R2 EE 64bit with 7.1 of 8.0 GB of RAM, 2 partition one with 67 of 175 GB free and the database with 139 of 273 GB free.

Hello

-> arg[ 34]: -Xmx2048M
-> arg[ 35]: -Xms2048M
-> arg[ 36]: -Xss2M

You need to expand the instance node and then check the memory assigned for the server0 node.

Regards

RB

[nelson_chamba2]

Hi Benjamin,

there are in 3 different places:

1. instance

2. dispatcher

3. server_ID

all of the have Xmx, Xms and Xss with different values, some of them has the 2048 and another 256.

What should I change and where?

regards,

nelson chamba\

[Reagan]

You need to look for the heap memory assignment of the server0 node.

That is where the error is.

Regards

RB

[nelson_chamba2]

Hi Benjamin,

I believe we are close but I still can´t find that, can you please help?

[Reagan]

Expand the part I have highlighted.

There you will see the dispatcher node and the server node.

Regards

RB

[nelson_chamba2]

Hi Benjamin,

Yes I can see and than?

[nelson_chamba2]

Hi Kamil,

this is not the case, the problem is:

Error occurred during initialization of VM

Could not reserve enough space for object heap

Now I don´t know which values should I set in order to make it run because so far it has -Xms2048 and -Xss2M

Any idea?

Best regards,

Nelson Chamba\

[Reagan]

Hello

Is it possible to restart the server and then start the SAP system ?

I wouldn't suggest changing any of he parameters now as the heap parameters are already set with the standard values.

What is the memory available on the machine ? You need to make sure that there is sufficient memory available on the server for the ABAP, JAVA and the database.

Regards

RB

[nelson_chamba2]

Hi Benjamin,

I restarted the server and the memory is 8GB, after starting the SAP instance it goes up till 7.1GB of usage.

Please see the screenshot for more details.

Hi Nelson,

Is there any logs under \usr\sap\<SID>\DVEBMGS01\j2ee\cluster\server0\log

application.log , defaultTrace.log

if yes please attach those.

Thanks,

[former_member183107]

Hi Nelson,

Please paste the logs of jvm: dev_disp and dev_jcontrol etc in /work folder.

also logs at location usr\sap\SID\JC<>\j2ee\cluster\server\\log.

from the screenshot i suppose you should wait for sometime as i can see some processes are running and then check the url.

Hello Nelson,

Upload logs such as bootstrap, dev_disp, sever.out jcontrol to investigate.
