How can i establish rpc properties with the datasource type DB in Corda community edition? - database

Question

To establish an RPC connection in the community edition we need to specify the rpc username, password and permissions but when we are integrating external database like MySQL and change the datasource type from INMEMORY to "DB" it does not allows to give user properties.
these are the settings I am using in my node.conf
security = {
authService = {
dataSource = {
type = "DB"
passwordEncryption = "SHIRO_1_CRYPT"
connection = {
jdbcUrl = "jdbc:mysql://localhost:3306"
username = "root"
password = "password"
driverClassName = "com.mysql.jdbc.Driver"
}
}
options = {
cache = {
expireAfterSecs = 120
maxEntries = 10000
}
}
}

Maybe I didn't understand your question, but database setup in node.conf is separate from RPC user setup in node.conf:
Database (PostGres in my case)
extraConfig = [
'dataSourceProperties.dataSourceClassName' : 'org.postgresql.ds.PGSimpleDataSource',
'dataSourceProperties.dataSource.url' : 'jdbc:postgresql://localhost:5432/postgres',
'dataSourceProperties.dataSource.user' : 'db_user',
'dataSourceProperties.dataSource.password' : 'db_user_password',
'database.transactionIsolationLevel' : 'READ_COMMITTED',
'database.initialiseSchema' : 'true'
]
RPC User
rpcUsers = [[ user: "rpc_user", "password": "rpc_user_password", "permissions": ["ALL"]]]
Ok, I'm adding my node's node.config (it's part of Corda TestNet, and it's deployed on Google Cloud):
baseDirectory = "."
compatibilityZoneURL = "https://netmap.testnet.r3.com"
emailAddress = "xxx"
jarDirs = [ "plugins", "cordapps" ]
sshd { port = 2222 }
myLegalName = "OU=xxx, O=TESTNET_xxx, L=London, C=GB"
keyStorePassword = "xxx"
trustStorePassword = "xxx"
crlCheckSoftFail = true
database = {
transactionIsolationLevel = "READ_COMMITTED"
initialiseSchema = "true"
}
dataSourceProperties {
dataSourceClassName = "org.postgresql.ds.PGSimpleDataSource"
dataSource.url = "jdbc:postgresql://xxx:xxx/postgres"
dataSource.user = xxx
dataSource.password = xxx
}
p2pAddress = "xxx:xxx"
rpcSettings {
useSsl = false
standAloneBroker = false
address = "0.0.0.0:xxx"
adminAddress = "0.0.0.0:xxx"
}
rpcUsers = [
{ username=cordazoneservice, password=xxx, permissions=[ ALL ] }
]
devMode = false
cordappSignerKeyFingerprintBlacklist = []
useTestClock = false
