The event_log had these three entries pointing to some DDL message with very large byte size:
Notice 2018-12-27 09:14:52.022000 6380 7972 Capture: Got Long DDL of length 339917, splitting into multiple msg with max length of 327277 (capturing from SOURCE_SID) [module oct]
Notice 2018-12-27 09:15:02.024000 6380 7972 Capture: Got Long DDL of length 663836, splitting into multiple msg with max length of 327277 (capturing from SOURCE_SID) [module oct]
Notice 2018-12-27 09:15:05.025000 6380 7972 Capture: Got Long DDL of length 423896, splitting into multiple msg with max length of 327277 (capturing from SOURCE_SID) [module oct]
The Capture DDL log (*ocap* *ddl*) contained a series of large DDLs (like PL/SQL procedures) as follows:
ocap_ddl 2018-12-27 09:14:45.021000 6380 7972 User Name: "SYS" Status: Not Replicated
ocap_ddl 2018-12-27 09:14:45.021000 6380 7972 DDL = CREATE OR REPLACE PROCEDURE procedure_name (
ocap_ddl 2018-12-27 09:14:45.021000 6380 7972 p_rdbms_version IN VARCHAR2,
ocap_ddl 2018-12-27 09:14:45.021000 6380 7972 p_apps_release IN VARCHAR2 )
ocap_ddl 2018-12-27 09:14:45.021000 6380 7972 IS
ocap_ddl 2018-12-27 09:14:45.021000 6380 7972 my_sequence INTEGER := 0;
ocap_ddl 2018-12-27 09:14:45.021000 6380 7972
ocap_ddl 2018-12-27 09:14:45.021000 6380 7972 PROCEDURE ins (
ocap_ddl 2018-12-27 09:14:45.021000 6380 7972 p_version IN VARCHAR2,
ocap_ddl 2018-12-27 09:14:45.021000 6380 7972 p_name IN VARCHAR2,
.

For all DDLs, whether replicated or not, there is a size limit of 327277 bytes for DDL logging in the Capture DDL log. DDLs over this size limit are split into chunks of 327277 bytes with the last chunk less than 327277 bytes. The log is located in /vardir/log directory where vardir refers to the variable directory of SharePlex. The event_log entries are for information purpose only and they do not impact replication in any way.
