hi guys i need help in creating oracles tap and target connector for my saas and also it should support version of oracle how can i do it

https://sdk.meltano.com/en/latest/dev_guide.html would be a good place to start. Worth noting that https://hub.meltano.com/extractors/tap-oracle and https://hub.meltano.com/loaders/target-oracle exist - have you tried these?

Hey Vikas, the quickest and easiest way to get this set-up is Meltano Cloud. You'll then have managed connectors that are kept up to date by the Meltano team. More than happy to walk you through the details, my calendar is open, here.
