SAP PI 7.1 - Runtime Workbench Error - "Service Unavailable"

[Former Member]

Hi there,

We have just installed SAP PI 7.1 on an iSeries 6.1 server, all seems to be successfully installed except that the runtime workbench will not start. It seems to be that the runtime workbench service was not deployed successfully during the install.

The error when trying to launch the Runtime Workbench is:

Application cannot be started!

Has anybody had this error before? Or how easy is it to manually re-deploy the service again?

Thanks for the help

I'm not sure if we the same issue as before here but definitely the reason I've encountered this type of error is that my Java is 1.4 and PI 7.1 requires 1.5.

I have just seen this on the forum as well which is exactly the same question that I have....

I will try it now and will let you know
