Why after upgrade to Archer 6.X release, some of the data feeds are failing with following error message
“An unexpected error has occurred: is_dde_filter_value_list_action_cumulative” ?
Here are more symptoms
- Data feed fails intermittently
- There are no logs in log file about this error
- Generally there is no details on ACP JOB engine monitoring plugin about this failed data feed
Root Cause
There is a additional instance of Archer JOB engine still running in environment ( probability "Disaster Recovery" ) This instance is not upgraded to latest Archer version but it can still connect with Archer instance data base and pick up JOBS from job queue. As it is running an older version, it will fail with error ( “An unexpected error has occurred: is_dde_filter_value_list_action_cumulative” )
Solution
Identify this host that is running older version of JOB engine using one of the following options
- ACP JOB engine monitor plugin.
- ACP Configuration report plugin to see if there are any additional JOB engine hosts
- Use database activity monitor to check incoming connections to instance database
Once all the hosts are identified, make sure that they are wither upgraded to same version or if they are not used, uninstall the JOB engine from that host.
