Composition Disaster Recovery - Mirroring

Hi Experts,

I am planning to setup Disaster Recovery site for the current Production.

The Environment is:

SAP NetWeaver 7.2 SR 1

DB2 9.1 on AIX 6.1

I am quite doubt on the strategy of mirroring the java. We have few CAFs and BPM running in current production.

Kindly provide your valuable inputs.

Regards,

Nikhil Bose
