Answer / shiv prakash tiwari

Only transparent tables and pooled tables can be buffered.
Cluster tables cannot be buffered.

The following two points speak against table buffering:-

1: The data read by the application must always be
up-to-date. Delays caused by the synchronization mechanism
cannot be accepted.

2: The table data is frequently modified. In this case the
cost of synchronization could be greater than the gain in
performance resulting from buffering. Roughly speaking, it
does not make sense to buffer a table if more than one
percent of the accesses to the table are modifying accesses.

Answer / harry

Buffering is primarily to speed up data retrieval. If a
table is buffered on application server, then database hits
will be reduced thereby speeding the ease of access.

There are 3 types of buffering: -

1. single record buffering : only one table record will be
buffered when it is read from database

2. Full table buffering: If one record is read from a table,
then all records of table will be buffered.

3. Generic buffering: - The table records matching generic
key are buffered. The generic key is the one that we define
while setting the buffering settings for table.
