Lite Vs Incremental Vs Full optimze ?

Question

Hi all,
I want to understand some basic things :
1- what is the difference between processing an application and optimizing it ?
I know that optimization moves data between fact, fac2 and wb tables, but what does the process do then ?
2 what is the difference between lite, incremental and full optimize
I think lite moves data from short term (wb) table to fac2 table but I am not sure of what the 2 other options do
thank you in advance

Answer 1

Optimizing applications
Optimization cleans up data storage which improves the responsiveness of the system. You should optimize your applications periodically to enhance system performance.
There is no rule of thumb for how often to run optimizations. The need can vary depending on the characteristics of your hardware environment and your application. However, you can set the system to remind you to optimize the application when the system database grows to a certain size.
Data storage types
Optimization options center around three different types of Business Planning and Consolidation data storage:
Data storage type
Real-time(FactWBTable)
This storage area holds the most recent data sent through BPC for Excel and BPC Web. Periodically clearing real-time data greatly optimizes the performance of the system. See the Lite Optimization option, below.
Short-term(Fact2Tale)
This is data that is not real-time data, but is also not in long-term storage yet. When you load data via Data Manager, it loads the data to short-term storage so that the loaded data does not affect system performance.
Long-term(FactTable)
This is your main data storage. All data eventually resides in long-term storage. Data that is not accessed very often remains in long-term storage so that the system maintains performance.
Optimization options
The optimization options interact with the three types of data storage in different ways:
Optimization type
Lite Optimization
Clears real-time data storage and moves it to Short-term data storage. This option does not take the system offline, so you can schedule it to run during normal business activity.
Incremental Optimization
Clears both real-time and short-term data storage and moves both to long-term data storage. This option takes the system offline, so it is best run at off-peak periods of activity.
Full Process Optimization
Clears both real-time and short-term data storage and processes the dimensions. This option takes the system offline and takes longer to run than the Increment Optimization. It is best run scheduled at down-time periods.
In the rare case that you have two application sets on the same server and two different applications from different application sets are optimized at the same time, you may receive an error message. To work around this issue, be sure to optimize applications for one Application Set at a time. It is especially important to schedule application optimization at different times when optimizing applications from different Application Sets that are on the same server.
