How to re-run particular instance of a node with MNI

I have the similar kind of issue, I have an array of 10 values and two of them have failed randomly. I can think of the possibility is to remove the success values and restart MNI with errorred one's. But how to identify for which value node has executed and which one failed.

Quick response is appreciated.

Thanks

How about putting your node in a sub process and configure MNI for the sub process instead. In this way you can put a retry mechanism on the node that could possibly fail.

Consider consolidating the node to write everything at once instead of using MNI.

Don't think you can re-start them. You could modify the process instance and pull out of the array that you're using for your mni all the failed ones and then add a new write to database node to process just those.

1. You can make use of "Get Processes By Node Status" plugin to get list of failed processes
nodes depending upon what process node status is being used ( e.g TASK STATUS PAUSED BY EXCEPTION = 8). You can pass specific failed DB node UUID . The UUIDs of the process nodes to be searched (see the Process Model documentation)

2. Design a process to pass above failed processes in batched manner to cancel the node first and then restart, you can use Process Management Services plugin to cancel and start a node

There is one more plugin available but i haven't tried the same.
