This looks like you have an error in your configuration. Is this a new install or upgrade? Is it a split schema? Please share the full PegaRules log file showing the start of the system.
From the error log I see 3 different schema references - schema1, schema2 and pegarules_aut. What are the actual names of your rules and data schemas? What database user are you using in your PegaRULES datasource?
In the startup logs we see that the default schema is set to pegasevenrules as you want. Was this system starting previously and all of a sudden stopped working? It seems like someone is setting up an environment in the PEGARULES_AUT schema and it is interferring with your environment.
It seems like there is a trigger PEGARULES_AUT.TRPR_DATAADM which is incorrectly linked to the PEGASEVENRULES.pr_data_admin table. You should have a PEGASEVENRULES.trpr_dataadm trigger in your schema. Get the trigger content for both versions so we can confirm that is what the issue is.
