Oracle 21c was released in Sept 2021, we should verify and test against this new version.

• Verify LogMiner compatibility
  • OracleClobDataTypeIT#shouldNotEmitClobFieldValuesWhenLobSupportIsNotEnabled
  • A side effect of the signalsSchemaChange below.

• Verify Xstream compatibility
  • OracleRowIdDataTypeIT#shouldSnapshotAndStreamRowIdAndURowIdColumnTypes
    This is unrelated to Oracle 21 and also fails on Oracle 19 since ROWID isn't compatible with XStream.
    This has been reported and will be fixed in DBZ-4702.

  • OracleSchemaMigrationIT#shouldNotEmitDdlEventsForNonTableObjects
    This is unrelated to Oracle 21 and also fails on Oracle 19; due to addition of Logback Logger which disabled a specific logger causing LogInterceptor assertions to fail.
    This has been reported and will be fixed in DBZ-4703.
