How to deactivate the exclusive mode of a decision rule ?

To verify if the mode of the table is exclusive :
peldsp display_ruletable -n table_name
result: rt_is_rules_table_exclusive='Y'

If the mode of the table is exclusive, you could modify that by this command:
peladm update_ruletable -n table_name -type XFER_CHANGE_STATE -excl N

To verify if the mode of the table is not exclusive :
peldsp display_ruletable -n table_name
result: rt_is_rules_table_exclusive='N'
