We have Oracle Database 18.104.22.168 with Database Vault functioning ok but we need to change two rule sets.
We modify the rule sets with dvsys.dbms_macadm.UPDATE_RULE_SET and the change was applied immediately.
After bounce the database the changes were lost and we have to applied again.
Specifically we want to change a rule set from no static to static so we run the following commands:
rule_set_name => 'Limit DBA'
,description => 'Limit DBA access'
,enabled => 'Y'
,eval_options => 2
,audit_options => 1
,fail_options => 1
,fail_code => NULL
,handler_options => 0
,handler => ''
,is_static => TRUE
