Multiple issues with execution of Schedules on Resource Pool

We are facing below issues while using Resource Pool.

  1. Session not getting created on one of the Resources in the pool
Description: We have a Schedule for Logging in to all the Resources. Schedule consists of One Task and in the Task we have 4 Scheduled sessions thrown on the Resource Pool. “Fail Fast on error” is disabled.
Requirement here is to start the Login process on all the Resources inside the Pool.
Issue: When this Schedule is executed, we observed that sometimes session is created only on 3 Resources out of 4. Even when all the Resources are idle. The error message seen in the Recent Activity report says “Session creation failed on resource ‘RobotsPool’: RobotsPool is too busy to run that process.”

  1. Session remains in “Pending” state for one of the Resources in the pool
Description: We have a Schedule for Logging in to all the Resources. Schedule consists of One Task and in the Task we have 4 Scheduled sessions thrown on the Resource Pool. “Fail Fast on error” is disabled.
Requirement here is to start the Login process on all the Resources inside the Pool.
Issue: When this Schedule is executed, we observed that sometimes sessions are created for all 4 Resources inside the pool, but one of the session remains in “Pending” state. It is not executed at all. It then needs manual intervention.

  1. If a Process running on a Resource from the Resource Pool is in Warning State, subsequent Schedules on the Resource Pool fail to execute
Description: We have multiple schedules on the Resource Pool named ‘RobotsPool’. This is the scenario where Schedule 1 starts executing a Process on the Bot Pool and if the Process runs into the “Warning” state.
Issue: Suppose a process, scheduled on the Resource pool somehow runs into a “Warning” state, then Schedule 2 and rest of the schedules executed on the Resource Pool fail to execute. Even when there are idle Resources available in the Pool. The error message seen in the Recent Activity report says “Session creation failed on resource ‘RobotsPool’: RobotsPool is too busy to run that process.”

If anyone has faced any or all of the above issues, please provide any pointers on how to make sure these issues do not arise.

Thanks,
Anish

Hi Anish,

  1. Session not getting created on one of the Resources in the pool
For error 1 i.e. “Session creation failed on resource ‘RobotsPool’: RobotsPool is too busy to run that process.”...check the size of BPAsesssionlog_nonunicode table...if this table is huge around 1TB or 2TB start and plan to reduce the session logs via running DB maintenance script provided by BP or archiving option in BP...you will see the error is gone...

2. Session remains in “Pending” state for one of the Resources in the pool
This also gets resolved once pt no 1 is fixed.

3. If a Process running on a Resource from the Resource Pool is in Warning State, subsequent Schedules on the Resource Pool fail to execute

Even this issue is resolve if pt no1 is fixed. however understand one thing if control machine of a pool is offline then complete pool is offline.
