The Replicat process maintains cursors for cached SQL statements and for SQLEXEC operations. Without enough cursors, Replicat must age more statements. By default, Replicat maintains as many cursors as allowed by the MAXSQLSTATEMENTS parameter. You might find that the value of this parameter needs to be increased. If so, you might also need to adjust the maximum number of open cursors that are permitted by the database. See Reference for Oracle GoldenGate for more information.
