ORA-01110

My Database Setup is :

Primary : 2 Node RAC 12.1.0.2 with Multitenant Architecture and ASM file structure

Standby : 2 Node RAC 12.1.0.2 with Multitenant Architecture and ASM file structure

During Data Guard Configuration, the standby file management was kept to manual (by mistake). After that we have created one new tablespace in primary database and which has shutdown the MRP process in Data Guard with below errors in alert log of standby instance.
