Hi all,

first let me preface this question with... I do not yet have access to the server or database and i have only seen 1 awr report and a the output from df-k and du.

I have an 11g database running on z-linux and frequently the thing starts swapping to disk.  The server has 72g of ram and it is not that heavily used.  some things that jumped out at me are
pga_aggregate_target       6442450944 or 6g
sga_max_size             59055800320  = 55g

Instance Activity Stats - Absolute Values
Statistic Begin Value End Value 
session pga memory max 3,872,656,816 3,125,364,624 
session cursor cache count 1,279,656 1,432,730 
session uga memory 63,353,187,248 63,755,218,768 
opened cursors current 15,253 17,204 
workarea memory allocated 172,094 261,297 
logons current 488 539 
session uga memory max 106,526,891,136 113,217,114,960 
session pga memory 2,009,472,880 2,236,766,544 

Open in new window


so the UGA is greater than the pga
another thing i noticed or rather didnt notice is the shmfs
I recall when installing 11g on redhat and using more than 25% of avail memory i had to set my shmfs or i would get memory_target not supported.

my question is on z-linux is the shmfs required as it is on redhat and is it acceptable to have the uga > pga

Thanks

Steve

first ,it's never acceptable to have uga>pga , something is really off , secondarily ,yes,You do have to set shmfs  ,z-linux can be more redhat in the installation but in the end it won't be pretty
