MongoDb: Request for input on changing wiredTigerCacheSizeGB value

+1 vote

In cluster environment, we have two shards (i.e primary, secondary and arbiter servers in each shard).

We have 64GB RAM and wiredTigerCacheSizeGB is currently 32 (by default). Here I need your advise, these serevers are dedicated to Mongo instances.

Can I change to wiredTigerCacheSizeGB to 50GB (leaving 14GB for OS and other processeses).

We are running MongoDB 3.0 with wiredTiger storage engine and wiredTigerCacheSizeGB is 24.
Now, I want to increase the wiredTigerCacheSizeGB value from 24 to 32. Is it possible to increase this variable without restart the service ?
