q: buffer busy wait(data block wait) when P3=130

all,

1. table cause the following waits had been identified. this table defined with default freelists and freelist group and intrans.
2. the session_wait p3 = 130 according to steve adams.

   1013 Block is being read by another session and no other  or 130 suitable block image was found, so we wait until the read

           is completed. This may also occur after a buffer cache
           assumed deadlock. The kernel can't get a buffer in a
           certain amount of time and assumes a deadlock. Therefore it
           will read the CR version of the block.

3. Question: would increaing freelists/freelist group/intrans would
             help in reducing data block wait when p3 = 130 ?

thnx ted chyn
