Hi Vlado,
I apologize for the very late reply. Unfortunately, opening a db tunnel was not reliable at the time we tried it. Sometimes we get the connection but most of the time it fails.
As another solution, I tried looking for a java webapp which I can deploy on HCP and that would act as our SQL client. I found RiverSql. Midway through my tinkering with the setup of the said app, the team decided to just move to Hana. Eclipse DTP works well with Hana DB.
Thanks,
Christine
