Review Comment:
This parameter "debezium.database.pdb.name" needs to be configured, but if
multiple partitions are executed, it will report a "table not found" error.
[issues/8463](https://github.com/apache/seatunnel/issues/8463#issuecomment-2650075780)
The reason is here in the
[complete](https://github.com/apache/seatunnel/blob/0fed6f605c77f19f0578b7f9d5bd577002c0c162/seatunnel-connectors-v2/connector-cdc/connector-cdc-oracle/src/main/java/org/apache/seatunnel/connectors/seatunnel/cdc/oracle/source/reader/fetch/scan/OracleSnapshotSplitReadTask.java#L173)
method, the jdbcConnection is reset to CDB. When the next partition uses the
same jdbcConnection, during the execution of doExecute, it tries to query PDB
tables in CDB, which results in a "table not found" error. So I added a check
in the prepare method to switch PDB.
