In my new microservices arch we are planning to 2PC protocol to handle distributed TX mgmt as we are using Oracle shared DB. I am unable to find any right implementation over the web. Is there any link having proper implementation for the same?

A proper documentation on how to implement 2Pc protocol using java spring boot

  • You don't need 2-phase commit when you only have one database. Commented Aug 8, 2023 at 12:27
  • how can i handle distributed transactions ? if any of my microservice fails i need to roll back my other microservices DB commits as well. Commented Aug 8, 2023 at 12:46
  • Your system should not have that requirement. stackoverflow.com/questions/52031350/… Commented Aug 8, 2023 at 12:51
  • i may be missing something here to understand your answer. Let me elaborate my expectation. I have microservice1(m1) calls M2 for updating few records and M2 calls M3 to update/insert few records. If in case M3 failed to update then my system should roll back M2 and M1 DB transactions as well. I hope i am clear with my questions here. Commented Aug 8, 2023 at 13:03
  • Yes, I understand. You think you should be able to do whatever you want in a distributed architecture, and there should be a way to make it fine... but you can't and there isn't. After M1 and M2 do their updates, everything might die. The DB needs to be left in a consistent and valid state if that happens. Commented Aug 8, 2023 at 13:19
