RHEL 5.6
one primary and three standby replica sets.
Local disk storage with RAID 10
RAM : 72GB
Db size: 73GB
OPLOG : 20GB
Description
Hi,
We want to change the oplog size to 50GB on primary database because of the stale replication issues.
after increasing the oplog,Will the local database(50GB) would be a part of mapped memory by mongod?
what should be the impact on overall database performance in a replication/journal enabled environment, if the size of the database is larger than the available physical memory on the system.
Thanks,
Rajesh Bhatt
