Re: ** keep/pin objects in sga

Eagle fan,
    Thanks. I tried to look up the REFERENCE manual for 9i but could not find 
explanation for x$ views : x$kghlu, x$ksmss, x$ksmsp
I did find v$ views listed. Can you tell where I can find the explanation. 
Thanks
  About cursor_space_for_time : My current shared pool is 600MB. If I set 
cursor_space_for_time to true then I assume I will need to increase the shared 
pool. Any way I can compute or guess how much I need to increase. Thanks 

  Go eagles.

  hi:

If you have literal sql issue, I suggest you use bind variables rather than 
cusor_sharing.

The parameter cursor_space_for_time is used to pin shared sql in shared_pool. 
You can find more info about this parameter..

For advance warning, you can check the x$ tables: x$kghlu, x$ksmss, x$ksmsp

     Thanks. So no short cut there. OK. So I guess we still need to do keeping 
of objects and sql. And put in bind variables. I assume there is some 
improvement in 9i in handling all this. Is there anything else that can be done 
to improve the sga usage and avoid its fragmentation and is there way to get 
advance warning when it is fragmented and could be heading for problems. Thanks

      cursor sharing still has a lot of bugs.
  it depends on the environment but tom kyte also  asked for the use of this 
only at session level rather than system level

Subject: ** keep/pin objects in sga

  Hi,
    For efficient use of shared pool and SGA : On 9i : I assume it is 
beneficial to keep objects and sql in sga. Or is it not needed on 9i? I think 
parameter CURSOR SHARING can be set to FORCE as alternative to using bind 
variables  and that will help SGA use but there were issues with it. I assume 
in 9i it is better. Any body with experience otherwise or any other catch? 
Thanks for your help.
