What r the types of lookup caches?

Persistent cache: U can save the lookup cache files and reuse them the next time the informatica server processes a lookup transformation configured to use the cache.

Recache from database: If the persistent cache is not synchronized with he lookup table,U can configure the lookup transformation to rebuild the lookup cache.

Static cache: U can configure a static or readonly cache for only lookup table.By default informatica server creates a static cache.It caches the lookup table and lookup values in the cache for each row that comes into the transformation.when the lookup condition is true,the informatica server does not update the cache while it prosesses the lookup transformation.

Dynamic cache: If u want to cache the target table and insert new rows into cache and the target,u can create a look up transformation to use dynamic cache.The informatica server dynamically inerts data to the target table.

shared cache: U can share the lookup cache between multiple transactions.U can share unnamed cache between transformations inthe same maping.

There are 2 important caches.
1. Static : By default integration service chooses statyic cache.It is read only cache . when you first query the lookup table, it caches the table. whenever a row comes into the transformation it caches lookup table and look up values. it doesn't update the chache.
2. Dynamic cache: data will be inserted dynamically to the look up cache as well as target table.
other types of caches are Persistaent, Shared and Rechace.
