Buffer space full

[Former Member]

Hi ,

--5 Program

| | |-----DirectoryUsed 9 % , Green 16.02.2010 , 12:12:13

| | |-----SpaceUsed 100 % , Red 16.02.2010 , 12:12:13

| | |-----HitRatio 100 % , Green 16.02.2010 , 12:12:13

| | |-----Swap 93.5 /min, Yellow 16.02.2010 , 12:12:13

CCMS shows error at space in red . this happening in case of Scren Bufer also

please guide me . is this a critical situation ? I need to increase space ? or just a restart is enough ?

Thank you Sir,

But this is DEV server , In Production there are more than 75 users logging in single day & swap count is more than 3.5 Lac

Is there big issue ahead ? & also it is possible to change parameters without restart ?

You need to do an analisys... excessive swapping is usually linked with bad configuration and could build performance issues. You need to restart your system after parameters changes (only dinamically switchable enabled parameters can be changed while system is running you can check that in RZ11)

Abap/buffersize is set to 600000 which is not a small value (depending on the size of your system)... simply is been used if the buffer gets full some swapping will happen, as far as I can see you have almost 100000 swaps that is not a small number.

Maybe you should consider increasing parameter abap/buffersize to 700000 and see how it goes... this will require a system restart

Check your program buffer parameters in ST02... and post them here
