# Informatica – Target Optimization

Overall as per my experience Tuning is a tricky and takes time. Target optimization involves both RDBMS and Flat files. Each area [you need](https://srinimf.com/2015/05/04/credit-cards-tokenization/) different optimization techniques. **[Read online complete Informatica interview questions Part-1.](https://srinimf.com/2015/08/24/informatica-interview-questions-part-1-of-2/)**

**Flat files**

Keep Target files in the shared directory, where usually stores only files. If the shared storage used by other tasks performance will be down.

**RDBMS**

- Drop indexes and Constraints
- Use pre-load, post-load [stored procedure](https://srinimf.com/2014/01/05/informatica-stored-procedure/)s
- Use pre-session and post-session SQL to do this activity
- Increase Database Checkpoint intervals
- Use BULK LOAD if required

**Use External Loader**

- For DB2, Oracle, Sybase, Terradata – You can use this method

**Minimize Deadlock**

- Use different database connection for each session

**Optimize target db**

- try to store table and index on separate discs
- Optimize oracle redo log
- Give proper storage space
