Is my JVM parameter setting correct?

[Former Member]

Hi all,

I have installed ERP, Solution Manager and Gateway on a single host. I never had a stable environment and I assume that my JVM configuration is not correct.

Would you like to review my JVM parameters as shown below?

Host and system details:

• I have installed an ERP system and Solution Manager on the same Windows box
• The host is Amazon EC2 instance running Windows 2008R2 SP1 Server 64 bit (total memory 15 GB and Processing Power 8 ECUs) .
• The ERP system is ERP 6.0 Support Release 3, MaxDB 7.8, Central System.
• The Solution Manager 7.1 Support Release 1, MaxDB 7.8, Central System.
• Gateway 2.0 on the top of the Solution Manager ABAP stack.
• SAP MaxDB version 7.8.02.26, the ERP and Solution Manager have their own DB.

The initial size of the paging file is 23038 MB and the Maximum is 65536 MB.

Many thanks for your help.

Regards,

Andreas

Hi

what you mean with stable environment? what error do you face? how many users connect to this box?

Let me know

Hi a,

at one day, all systems are running and without any changes, I am not able to restart a system anymore. Some processes did not work in the past. I am hosting the SAP system in a virtual environment so that I am able to roll back the systems to the last persisted state. After that, all systems are working again.

Right now, it is just a single person using the system.

I am not a SAP admin so that I do not know the right configuration. I would like to know whether my JVM configuration makes sence.

Many thanks for your questions.

Regards,

Andreas
