Log Segments With 'RetainedFree' Status

Problem: There are many log segments on the Primary site with the status "RetainedFree".

Solution:

1. Disable the replication on the Primary Site

hdbnsutil -sr_disable --force

2. Reclaim the logsegments

Alter system SAVEPOINT;

Alter system RECLAIM LOG;

3. Enable the replication on the Primary Site.

hdbnsutil -sr_enable --name=<PrimarySiteName>

Notes: 

For Reference, there are couple of Snotes that are helpful.
