Oracle: io.vertx.core.VertxException: URLs with multiple hosts are not supported

[AbuzarHussain]

Version

vertx-oracle-client 4.3.2

Context

I'm unable to connect to the oracle instance with failover/clustering configuration. The connectionURI is constructed in EZConnect format and passed to fromUri() method, below is the example snippet,

const connectOptions = OracleConnectOptions.fromUri("oracle:thin:@host1,host2...hostn:port/service_name?failover=on&retry_count=30&retry_delay=10")
.setUser(username)
.setPassword(password)

 const poolOptions = new PoolOptions()
  .setMaxSize(maxPoolSize)
  .setShared(true)

 client = OraclePool.pool(vertx, connectOptions, poolOptions)

An exception is thrown :
java.lang.IllegalArgumentException: Cannot parse invalid connection URI: oracle:thin:@host1,host2,host3,host4:port/service_name?failover=on&retry_count=30&retry_delay=10 -> at io.vertx.oracleclient.impl.OracleConnectionUriParser.parse(OracleConnectionUriParser.java:55) -> at io.vertx.oracleclient.impl.OracleConnectionUriParser.parse(OracleConnectionUriParser.java:28) -> at io.vertx.oracleclient.OracleConnectOptions.fromUri(OracleConnectOptions.java:89) -> at io.reactiverse.es4x.impl.EventEmitterImpl.emit(EventEmitterImpl.java:44) -> at io.reactiverse.es4x.ESVerticleFactory.waitFor(ESVerticleFactory.java:184) -> at io.reactiverse.es4x.impl.JSVerticleFactory.access$100(JSVerticleFactory.java:25) -> at io.reactiverse.es4x.impl.JSVerticleFactory$1.start(JSVerticleFactory.java:84) -> at io.vertx.core.impl.DeploymentManager.lambda$doDeploy$5(DeploymentManager.java:196) -> at io.vertx.core.impl.ContextInternal.dispatch(ContextInternal.java:264) -> at io.vertx.core.impl.ContextInternal.dispatch(ContextInternal.java:246) -> at io.vertx.core.impl.EventLoopContext.lambda$runOnContext$0(EventLoopContext.java:43) -> at io.netty.util.concurrent.AbstractEventExecutor.runTask(AbstractEventExecutor.java:174) -> at io.netty.util.concurrent.AbstractEventExecutor.safeExecute(AbstractEventExecutor.java:167) -> at io.netty.util.concurrent.SingleThreadEventExecutor.runAllTasks(SingleThreadEventExecutor.java:470) -> at io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:503) -> at io.netty.util.concurrent.SingleThreadEventExecutor$4.run(SingleThreadEventExecutor.java:997) -> at io.netty.util.internal.ThreadExecutorMap$2.run(ThreadExecutorMap.java:74) -> at io.netty.util.concurrent.FastThreadLocalRunnable.run(FastThreadLocalRunnable.java:30) -> at java.base/java.lang.Thread.run(Thread.java:829) -> Caused by: io.vertx.core.VertxException: URLs with multiple hosts are not supported yet ->

Hi team, We're currently holding our next release because of this issue. As the milestone is set to vertx 4.3.5, can you please let me know when the vertx 4.3.5 would be released along with this fix? so that we can plan accordingly.

It's not planned yet, we've just released 4.3.4.

In the meantime, you can put your connection settings in a tnsnames file and use a tns alias in connection URI (see https://vertx.io/docs/vertx-oracle-client/java/#_connection_uri)
