Method Details

resolveScn

protected Scn resolveScn(Document document)

areSameTimestamp

protected boolean areSameTimestamp(Scn scn1,
 Scn scn2,
 OracleConnection connection)
                            throws SQLException

Checks whether the two specified system change numbers have the same timestamp.

Parameters:

scn1 - first scn number, may be null

scn2 - second scn number, may be null

connection - the database connection, must not be null

Returns:

true if the two system change numbers have the same timestamp; false otherwise

Throws:

SQLException - if a database error occurred

getLatestTableDdlScn

protected Optional<Scn> getLatestTableDdlScn(RelationalSnapshotChangeEventSource.RelationalSnapshotContext<OraclePartition,OracleOffsetContext> ctx,
 OracleConnection connection)
                                      throws SQLException

Returns the SCN of the latest DDL change to the captured tables. The result will be empty if there is no table to capture as per the configuration.

Parameters:

ctx - the snapshot contest, must not be null

connection - the database connection, must not be null

Returns:

the latest table DDL system change number, never null but may be empty.

Throws:

SQLException - if a database error occurred
