All,
Our SA is considering setting the max open files from 2048 to 30K. This sounds like a drastic change. Does anybody have an idea of the negative impacts of increasing the open files too high? Would like to know if this change could negatively impact our system. What test should we run to... (2 Replies)

Morning,
Somebody can tell me in AIX 6.1 what is the different between the maxuproc (lsattr -El sys0 | grep max) and the for a user.
Example:
Oracle is limited by :

But lsattr -El sys0| grep maxuproc show me :
maxuproc 16384

NAME
profile - DTrace profile interrupt provider
DESCRIPTION
The profile driver is a DTrace dynamic tracing provider that adds time-based interrupt event sources that can be used as DTrace probes.
Each profile event source is a time-based interrupt firing every fixed, specified time interval. You can use these probes to sample some
aspect of system state every unit time and the samples can then be used to infer system behavior. If the sampling rate is high, or the sam-
pling time is long, an accurate inference is possible. By using the DTrace facility to bind arbitrary actions to probes, you can use the
profile provider to sample practically anything in the system. For example, you could sample the state of the current thread, the CPU
state, or the current machine instruction each time a probe fires.
The profile driver is not a public interface and you access the instrumentation offered by this provider through DTrace. Refer to the
Solaris Dynamic Tracing Guide for a description of the public documented interfaces available for the DTrace facility and the probes
offered by the profile provider.
