Review Comment:
@hailin0 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 session, which results in a "table not found" error. So I added
a check in the prepare method to switch PDB.
