Development Preparations

• For downloading and installing Java SDK, see Java.
• If this is your first time using BatchCompute, please see Preparation.

Getting Started

import java.util.TreeMap;
import com.qcloud.QcloudApiModuleCenter;
import com.qcloud.Module.Batch;
import com.qcloud.Utilities.Json.JSONObject;
public class BatchDemo {
      public static void main(String[] args) {
              TreeMap<String, Object> config = new TreeMap<String, Object>();
              config.put("SecretId", "Your secretId");
              config.put("SecretKey", "Your secretKey");
              config.put("RequestMethod", "GET");
              config.put("DefaultRegion", "gz"); // Region, gz: guangzhou
               QcloudApiModuleCenter module = new QcloudApiModuleCenter(new Batch(), config);
      }
}

Creating a Compute Environment

TreeMap<String, Object> envParams = new TreeMap<String, Object>();
envParams.put("ComputeEnv.EnvName", "batch-env");  // Compute environment name
envParams.put("ComputeEnv.EnvType", "MANAGED");
envParams.put("ComputeEnv.DesiredComputeNodeCount", 10);  // Number of desired nodes
envParams.put("ComputeEnv.EnvData.InstanceType", "S1.SMALL1");  // Instance type
envParams.put("ComputeEnv.EnvData.ImageId", "img-er9shcln"); // Image ID
envParams.put("ComputeEnv.EnvData.SystemDisk.DiskType", "LOCAL_BASIC");  // System disk type
envParams.put("ComputeEnv.EnvData.SystemDisk.DiskSize", 50);  // System disk capacity
envParams.put("ComputeEnv.EnvData.LoginSettings.Password", "B1[habcdB1[habcd");  // Login password
envParams.put("Placement.Zone", "ap-guangzhou-2");  // Availability zone
envParams.put("Version", "2017-03-12");
String createRes = null;
try {
  createRes = module.call("CreateComputeEnv", envParams);
  JSONObject result = new JSONObject(createRes);
  System.out.println(result);

  result = result.getJSONObject("Response");
  System.out.println(result.getString("EnvId"));
} catch (Exception e) {
  System.out.println("error..." + e.getMessage());
}

Modifying a Compute Environment

TreeMap<String, Object> envParams = new TreeMap<String, Object>();
envParams.put("EnvId", "env-cc44pzme");  // Compute environment ID
envParams.put("DesiredComputeNodeCount", 100);  // Number of desired nodes
envParams.put("Version", "2017-03-12");
String modRes = null;
try {
  modRes = module.call("ModifyComputeEnv", envParams);
  JSONObject result = new JSONObject(modRes);
  System.out.println(result);
} catch (Exception e) {
  System.out.println("error..." + e.getMessage());
}

Deleting a Computer Cluster

TreeMap<String, Object> delParams = new TreeMap<String, Object>();
delParams.put("EnvId", "env-cc44pzme");  // Compute environment ID
delParams.put("Version", "2017-03-12");
String delRes = null;
try {
  delRes = module.call("DeleteComputeEnv", delParams);
  JSONObject result = new JSONObject(delRes);
  System.out.println(result);
} catch (Exception e) {
  System.out.println("error..." + e.getMessage());
}

Viewing the Creation Information of the Compute Environment

TreeMap<String, Object> infoParams = new TreeMap<String, Object>();
infoParams.put("EnvId", "env-cc44pzme");  // Compute environment ID
infoParams.put("Version", "2017-03-12");
String infoRes = null;
try {
  infoRes = module.call("DescribeComputeEnvCreateInfo", infoParams);
  JSONObject result = new JSONObject(infoRes);
  System.out.println(result);
} catch (Exception e) {
  System.out.println("error..." + e.getMessage());
}

Viewing the Compute Environment Information

TreeMap<String, Object> desParams = new TreeMap<String, Object>();
desParams.put("EnvId", "env-cc44pzme");  // Compute environment ID
desParams.put("Version", "2017-03-12");
String desRes = null;
try {
  desRes = module.call("DescribeComputeEnv", desParams);
  JSONObject result = new JSONObject(desRes);
  System.out.println(result);
} catch (Exception e) {
  System.out.println("error..." + e.getMessage());
}

Viewing the List of Compute Environments

TreeMap<String, Object> listParams = new TreeMap<String, Object>();
listParams.put("Version", "2017-03-12");
String listRes = null;
try {
  listRes = module.call("DescribeComputeEnvs", listParams);
  JSONObject result = new JSONObject(listRes);
  System.out.println(result);
} catch (Exception e) {
  System.out.println("error..." + e.getMessage());
}
