System p550 2 PCU (partition into 4) AIX 5.3L, memory 3790 M, with BAAN 5c on hdisk2 and Oracle 10g on hdisk1 (data on hdisk3)
Last night, I modified three parameters maxuproc (sys0)= 512, maxservers (aio0) =300 and and lgpg_regions = 119 (16M), based on SGA of Oracle.
However, as the busy hour, the topas indicated that the hdisk0, which is all of OS programs staged, is always 95% busy, and there seem to have high % of read (Kb-read) and write (K-write). On the hand did not indicated busy CPU% by any user. Some high number of PageIn and Pageout.
I have another set of AIX test box with very similar set up (same hw, same parameter setups, same programs setup). but testing the BAAN/Oracle did not show very busy on hdisk0.
So how can I solve the problem? very urgent! Please help.
