Alternatives for Dblink in oracle?

Question

we have an SSIS job that inserts data into a table in server A from data in table which is located in some other server B.

For this,we are making use of dblinks to connect to other database . But, this is causing lot of performance issues and job is failing because it is taking lot of time to execute the query.

So, i would like to know , what are the alternatives for Dblinks. The one thing i got is , using Materialistic views .

BUt i am not sure , how that works ? Please suggest..
