What causes the wallet functions to be disabled?

Question

I have run bitcoind as a server on one host. On a second host, I have configured bitcoin-cli to interact with bitcoind. However, all wallet commands are now disabled with this new configuration. When I run simple commands such as:

bitcoin-cli listaccounts

or

bitcoin-cli getaccountaddress "new_account"

I get:

error: {"code":-32601,"message":"Method not found (disabled)"}

When I call any other bitcoin-cli method that does not involve wallets, I get a normal response.

What is happening? What causes the wallet functionality to be disabled?

The configuration file reads as follows:

server=1
rpcuser=jared
rpcpassword=1234
rpcport=8332
rpcallowip=192.168.0.0/16
gen=0
prune=600

Answer 1

In Bitcoin Core 0.11 pruning is experimental, and incompatible with the wallet.

So turning on the prune= option automatically disables the wallet function.

In 0.12 the wallet will work with pruning (though you obviously won't be able to rescan past the pruning cutoff).
