We have deployed consortium ethereum block chain in azure portal. I don't have access to the azure portal except the cloud url. By using the cloud url i have wrote the nodejs code with web3 api to get the balance and unlock the account and send the transaction.I got the getBalance but When i am trying to unlock the account it's showing me error "Failed to unlock the personal_unlock account is not available or does'nt exist" and i am unable to proceed further for the transaction. What should i do?

This is probably because the Ethereum node started does not expose personal api of the geth interface. This can be changed by starting the rpc server with the rpcapi flag specifying which api's of geth to expose on RPC. By default when a rpc server is started it does not expose all the api of geth through RPC due to security reasons. You can find how to start a node by exposing required modules of the geth API here.

  • Hi Thanks for your response. Do u mean that we should run those commands in azure? – prasanna Aug 3 '17 at 12:39
  • Yes, you will have to restart the RPC server exposing the required API. – joifsi Aug 3 '17 at 15:24
