Compare marker lost, since the table is skipped by read param.

set param SP_ORD_SKIP_OBJECT <table_id>

1.Source
sql>select object_id, owner from dba_objects where owner='SPLEX' and object_name='SHAREPLEX_DATAEQUATOR';
sp_ctrl>set param SP_ORD_DEBUG_OBJECT <object_id> --for SHAREPLEX_DATAEQUATOR
sp_ctrl>set param SP_OCT_GEN_DEBUG_OBJID <object_id> --for SHAREPLEX_DATAEQUATOR
sp_ctrl>show read internal
sp_ctrl>show capture detail
sp_ctrl>qstatus

Target
sp_ctrl>set param sp_opo_debug_flag 0x00010000
sp_ctrl>show post detail
sp_ctrl>qstatus

2.compare again
sp_ctrl>reset param SP_ORD_DEBUG_OBJECT
sp_ctrl>reset param SP_OCT_GEN_DEBUG_OBJID
sp_ctrl>reset param sp_opo_debug_flag

3.Check source & target log, confirm DEQ MARKER exist or not
source side:
compare server log
event_log, *ocap*.log, *ord*.log

target side:
compare client log,
event_log
*opo*.log

reset param SP_ORD_SKIP_OBJECT

SP_OPO_DISABLE_OBJECT_NUM may also affect compare.
