If you want a trigger to be enabled on golden gate target then you need to explicitly define it in replicat file. By default trigger firing is disabled

add belwo line in replicat file. schema – INFRA, trigger – AUDIT_TRIG

SQLEXEC "begin dbms_ddl.set_trigger_firing_property('INFRA','AUDIT_TRIG',FALSE); end;"

after chnage file will look like this

Replicat R1
SETENV(ORACLE_HOME="/u01/oracle/product/12.1/db_1")
SETENV(ORACLE_SID = "TROY_1")
AssumeTargetDefs
DiscardFile ./dirrpt/rpdw.dsc, append, megabytes 4096
SOURCECHARSET PASSTHRU
UserID ggadmin@TROY, Password ggadmin
DDL INCLUDE ALL
DDLERROR DEFAULT IGNORE
map  INFRA.*, target INFRA.*;
SQLEXEC "begin dbms_ddl.set_trigger_firing_property('INFRA','AUDIT_TRIG',FALSE); end;"

to disable set TRUE
