Saving an index ddl and restore it

Question

HI during our ETL load we need to drop the index and then after the load recreate it.
So we are doing a procedure that will store all the ddl of the corresponding index so the interface will be something like
savedropidx(schema_name,table_name,index_name)
savedropidx(schema_name,table_name) --all the index of that table
savedropidx(schema_name) --all the index of that schema
restoreidx(schema_name,table_name,index_name)
restoreidx(schema_name,table_name) --all the index of that table
restoreidx(schema_name) --all the index of that schema
we would use dbms_metadata to get the ddl.  and store it onto the table and when the bulk load is done we restore those indexes based on the saved ddl definition
Is this a good approach or another alternative approach ?
Also if there is foreign key involved this can be hairy ? any thought on that one ?

Answer 1

actually it looks like it can be only run as sys or invoker. so is there a way I can still run it as pl/sql using dbms_metadata and not login as sys ??
the approach we thought in mind will not work as roles are disabled..
From  dbms_metadata 11g release 2 doc.
In stored procedures, functions, and definers-rights packages, roles (such as SELECT_CATALOG_ROLE) are disabled. Therefore, such a PL/SQL program can only fetch metadata for objects in its own schema. If you want to write a PL/SQL program that fetches metadata for objects in a different schema (based on the invoker's possession of SELECT_CATALOG_ROLE), you must make the program invokers-rights.
