# Run stored procedures in other schemas from stored procedure

oracleoracle-12cparallelismstored-procedures

I have a current process: a large procedure in one schema.
There is a plan to have A, B1, B2, B3 schemas (B-schemas are identical, could be B-n schemas) in Oracle 12c database.
Schemas B1, B2, B3 have synonyms to A.
Schema A stores all the connections information to other schemas.

Is it possible to run a stored procedure in A and call the stored procedure in other B-schemas (dynamically determine schemas to run and do it in parallel).

There is also .Net part and it is better to put this logic there and make calls to the B-schemas stored procedure in different threads?
