Creating a role with read only and execute privileges on APPS schema in EBS R12.1.3

Hi All,

Please help me in creating a role with "read only and execute privileges" on apps schema on Oracle EBS R12.1.3.

Once role is created, I have to assign this role to our newly joined DBA team members.

Instead of creating apps read only users or using apps schema, we have to assign this role to the team members.

Request you to please provide any resolution

Thanks,
