Setup Sequence Replication
Oracle GoldenGate supports Oracle Sequences replication.There are some limitations with sequence replication.
1.sequence replication in bi-directional is not supported
2.cache size,increment interval,and cycle/no-cycle settings must be identical on source and target databases

Setup Heartbeat Job
In order to start the pump,we need to make target 11g database server ready,by installing Oracle GoldenGate and starting manager.Before we do that lets setup a heartbeat job in cron.
The purpose of heartbeat job is to keep updating ggs_mon.ggs_heartbeat table,those transactions will be extracted by Oracle GoldenGate,causing extract RBA to move,and also keep record of lag time in ggs_lagtime table on the target side.
[oracle@zwc ~]$ cd /ggs
[oracle@zwc ggs]$ mkdir scripts
[oracle@zwc ggs]$ touch ggs_heartbeat.sh
[oracle@zwc ggs]$ chmod 755 ggs_heartbeat.sh
[oracle@zwc ggs]$ cat ggs_heartbeat.sh
#!/bin/sh
#Purpose: To update heartbeat table for OGG monitoring
cd ${HOME}
source ${HOME}/.bash_profile > /dev/null 2>&1
echo $GG_HOME
cd $GG_HOME
DATETIME=`date`
echo "Heartbeat for DB ${ORACLE_SID} start at ${DATETIME}…
"
sqlplus -L -S ggs_mon/ggs_mon << EOF 2>&1
update ggs_heartbeat set ts = sysdate;
commit;
exit
EOF
Setup cron for this to run every minute
* * * * * /ggs/ggs_heartbeat.sh > /tmp/ggshb.log 2>&1

Also in replicat we have not created yet,but when we will create replicat parameter file,then we will add following MAP statement in it to make heartbeat work properly.
MAP ggs_mon.ggs_heartbeat, TARGET ggs_mon.ggs_lagtime,
KEYCOLS (ID),
INSERTALLRECORDS,
COLMAP (USEDEFAULTS,
id = 0,
committime = @GETENV ("GGHEADER", "COMMITTIMESTAMP"),
groupname = @GETENV ("GGENVIRONMENT", "GROUPNAME"),
host = @TOKEN("host"),
local_insert_time = @DATENOW()
);
Now if we invoke ggsci and run "info" command on extract couple of times after few intervals,we will be able see that its RBA is moving even when there is no application activity going on in the database.
