In 1PC, a single coordinator manages the transaction. It contacts all involved nodes (participants) to ensure their readiness for commit. If all nodes are ready, the coordinator initiates the commit phase, where all participants execute the transaction. If successful, the coordinator sends a commit message, otherwise, it sends an abort message. This protocol is simple but has limitations in ensuring atomicity and reliability. 2PC involves a coordinator and multiple participants. It operates in two phases: the prepare phase and the commit phase. During the prepare phase, the coordinator asks participants if they are ready to commit. If all participants agree, it proceeds to the commit phase; otherwise, it aborts the transaction. This protocol ensures atomicity but can suffer from blocking issues if the coordinator fails during the process.

where exactly we can check that we are having database connection leaks or not ?

A connection which is not handed over to the connection pool once work is finished called the leaked connection. You have to observe the patterns, in case of leak connection pool your pool will always get out of connection or you will see multiple inactive connections at db

dbping is to test connectivity between weblogic and db host, you have to provide username and password in dbping as well. If you want to connect db to connect SQL prompt to work on db then you have to install Oracle db client on weblogic host
