How to Reload Manager Parameters without Restarting

Many services in Linux support reload action to make new parameter file take effect online without restarts. For example,

[oracle@test ~]$ systemctl reload httpd.service

In the same concept, we can also reload GoldenGate Manager parameter online without interrupting EXTRACT, PUMP or REPLICAT working process.

GGSCI (chicago) 6> refresh mgr
