MaxDB on VMWare - sometimes JDBC interrupts

Former Member

Hi,

we have MAxDB 7.7 installed on VMWare (2 Core, 6 GB cacheSize; community licence).

An non sap application establishes some JDBC connections to this database. Sometimes a jdbc call does not work and I'm getting an error (but no SQL-Error).

If the MaxDb is installed on an application server without VMWare everything works.

Do I have to change some MaxDB parameters for running under VMWare?

Regards

community license - doesn't matter for the technical background.

There is no difference to the code that SAP customers get.

Ok, but what kind of error do you get?

Where do you see the error?

Have you checked the KNLMSG log and the XServer log ?

No, there aren't any special parameter settings.

It would be odd though, since virtualisation is meant to be totally transparent for the code running inside the virtual machine, wouldn't it?

So maybe there is something with the VMWare not working correctly.

Is the network constantly available (e.g. no DHCP re-inits or something the like)?

And: what os are you using?

regards,

Lars
