Answer / swetha
Persistent cache: yoU 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, yoU 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 you want to cache the target table and
insert new rows into cache and the target, you can create a
look up transformation to use dynamic cache.The informatica
server dynamically inerts data to the target table.
shared cache: yoU can share the lookup cache between
multiple transactions.yoU can share unnamed cache between
transformations inthe same maping.

Answer / rekha
Types are
STATIC CACHE : IT IS A READ ONLY CACHE USED FOR SINGLE
LOOK UP
DYNAMIC CACHE : USE THIS CACHE TO REFLECT THE CHANGED DATA
DIRECTLY ,WHEN THE TARGET TABLE IS LOOKUP
SHARED CACHE : THE CACHE USED AMONG MULTIPLE SESSIONS
PERSISTANT CACHE : THE CACHE USED AMONG MULTIPLE
TRANSFORMATIONS

Answer / anushka jain
Lookup Cache boost the performance of look up by reading the data from lookup source only once and then using it for for rest of the mapping. We can enable the Cache by checking the “Lookup caching Enabled†in the Properties tab of lookup Transformation.
Different Type of Cache are
1.static cache
2.dynamic cache
3.persistant cache
4.shared cache
