I am using TRU Unix 64 V 5.1A. I have an Oracle database sitting on it. Now both the OS and DB are now moving fairly slowly. To improve/enhence performance I am assuming one starts by tuning Hardware, then OS and lastlty DB.(First Question: is this assumption valid?). Hower at the present moment i do not have the resources to enhence the hardware, and that gets me to the OS.
Currently my space operates at btwn 80 and 98% of the 177 GB Raid 5 Hard Disks. (The system really gets worse after 96% and i clean up some unncessary log files to bring it back to 80% - still its not good enough) CPU usage is usually below 40%. However I am not sure footed on analysing the 2GB memory that i have. Second Question is how do i analyse the memory and third question is are there other aspects of the OS worth looking at before moving to the DB. (My DB questions will be in the Oracle area!). Thanx.
