Database 名称为'；传感器信息表'；已由其他人在DolphinDB中注册

我部署了一个具有6个数据节点的DolphinDB集群。我想模拟一个场景，其中600个设备每100ms收集一次数据，然后将其写入流表。在每个数据节点中，订阅者订阅流表并将数据写入数据库。我编写sql代码如下：

//create stream table, then subscribe it
def PrepareStreamEnv(){
  clearAllCache()
  n = 1000000;
  tableSchema = streamTable(n:0,`hardwareId`ts`temp1,[INT,TIMESTAMP,DOUBLE])
  share(tableSchema,"sensorInfoTable")
  enableTablePersistence(objByName("sensorInfoTable"), false, false, n)

  //dfs subscribe 
  dfsTable = loadTable("dfs://iotDemoDB0","sensorInfoTable")
  subscribeTable(, "sensorInfoTable", "save_to_db", -1, append!{dfsTable}, true,50000,1)
}
// create database
def prepareDatabase(){
  tableSchema = table(100:0,`hardwareId`ts`temp1,[INT,TIMESTAMP,DOUBLE])
  if(exists("dfs://iotDemoDB0"))
      dropDatabase("dfs://iotDemoDB0")
  db1 = database("",VALUE,(today()-1)..(today()+1))
  db2 = database("",RANGE,0..60*1000)
  db = database("dfs://iotDemoDB0",COMPO,[db1,db2])
  dfsTable = db.createPartitionedTable(tableSchema,"sensorInfoTable",`ts`hardwareId)
}
//clear stream environment
def clearStreamEnv(){
  clearTablePersistence(objByName("sensorInfoTable"))
  unsubscribeTable(,"sensorInfoTable","save_to_db")
}
//write a record for every devices
def writeData(hardwareVector){
  hardwareNumber = size(hardwareVector)
  return table(take(hardwareVector,hardwareNumber) as hardwareId ,take(now(),hardwareNumber) as ts,rand(20..41,hardwareNumber) as temp1)
}

def simulate(hardwareIds,interval,freq){
    hardwareNum=size(hardwareIds)
    PrepareStreamEnv()

    t=objByName("sensorInfoTable")
    for(i in 0:freq){
        t.append!(writeData(hardwareIds))
        sleep(interval) 
    }
    clearStreamEnv()
}
def mainJob(interval,freq,devices){
  nodes = getDataNodes()
  nodeCount = nodes.size()
  hardwareVectors = cut(0..(devices*nodeCount - 1), devices)
  jobids=array(string, nodeCount, 10);
  prepareDatabase()
  for( index in 0:nodeCount){
      rpc(nodes[index], submitJob, "submit_" + nodes[index], "submit_" + nodes[index], simulate{hardwareVectors[index], interval, freq})
  }
 }

 login("admin","123456")
 interval = 100
 freq =50
 devices = 1000
 mainJob(interval,freq,devices)

我在GUI中执行代码，但发现数据库中的表中没有插入任何记录。然后我执行以下代码来获取作业的信息

pnodeRun(getRecentJobs)

结果表明。如何解决它
