Adeptia checks available resources on every node of the cluster before allocating a job in round-robin method. In other words, Adeptia system will first check the availability of the resources on every node before randomly allocating the job to the relevant node. If resources are not available it will move to the next node and check again before allocating the job.
To enable resource-based allocation in Clustering:
- Go to ...\AdeptiaSuite-6.9\AdeptiaServer\ServerKernel\etc\cluster.
- Open cluster properties file.
- Change the value of cluster.load.balance.policy from Round-Robin to Resource-Based-Round-Robin.
That is, change cluster.load.balance.policy=Round-Robin to
cluster.load.balance.policy=Resource-Based-Round-Robin
- Save the file.
- Restart Kernel and WebRunner.
After you have enabled resource-based allocation of jobs in the Cluster Properties file, you should give threshold value of each of the resource. Note that these values should be same for all the nodes of a cluster. To set the values:
- Login to Adeptia Suite.
- Go to Administer > Setup> Application Settings.
- From Application Settings, go to Update System Properties > Load Management.
- In Load management set the threshold in relevant property.
- Click Save.
Users can view the notification about unsuccessful allocation of the job to a node in the kernel logs file.
