Answer 1

all configurations was ok and working fine (meaning data was extracted on source and replayed on target) before extract/replicat processes restart
I did not touch any of the configuration files, after restart processes shows as up & running without any actual errors or rejects on the logs
please find extract configuration file:
EXTRACT e_enva
SETENV ( ORACLE_SID=orcl )
USERID USER_SCHEMA_A, PASSWORD AACAAAAAAAAAAAHAOFVCXAUANCVHIHCE, ENCRYPTKEY DEFAULT
DISCARDFILE C:\GG\dirrpt\e_enva.dsc, APPEND, MEGABYTES 10
REPORTCOUNT EVERY 10000 RECORDS, RATE
NOTRACETABLE
EXTTRAIL C:\GG\dirdat\enva\ce
SQLEXEC "CALL USER_SCHEMA_A.pkg.event_message('START', null, 'ALL','e_enva')";
SQLEXEC "CALL USER_SCHEMA_A.pkg.event_message('STOP', null, 'ALL','e_enva')" ONEXIT;
TABLE USER_SCHEMA_A.T_TABLE, KEYCOLS (ID_OBJECT);
TABLE USER_SCHEMA_A.T_TABLE_REF, KEYCOLS (ID_XREF, PKEY_SRC, SYSTEM, IND);
logging and supplemental logging enabled, commits performed and again nothing was changed in configuration except that processes was restarted
thank you
