Good evening all, I have a very interesting issue. I have an oracle database on unix and nt. The dba says that his delete process runs in 22 mins on nt. When I run the same delete process on unix, it run in an hour. I downloaded sarcheck to see what was going on. It told me abpout the autoup... (3 Replies)

hi,
I am trying to determine a 'rule of thumb' threshold for memory usage on different Solaris versions.
I know that prior to Solaris 8, "page scan rate > 300" can be used as a general rule of thumb to determine any memory shortages. Since Solaris 9 and 10 have a different memory handling... (2 Replies)
Dear all,
I have a Local zone , where users feel that performance is not good.
Is it wise to collect the inputs from the local zone rather than taking from the global zone.
And also Can I tune from Global zone , so that it will reflect in local zone.

We have a SPARC T4-1 server, running Solaris 11, and it's doing some pretty extensive parsing on roughly 100GB data set.
All was well still few weeks ago, when I was testing the performance, I was reaching rougly 50minute calculation times, and it was more or less expected performance.
Now... (0 Replies)
I have identical M5000 machines that are needing to transfer very large amounts of data between them. These are fully loaded machines, and I've already checked IO, memory usage, etc... I get poor network performance even when the machines are idle or copying via loopback. The 10 GB NICs are... (7 Replies)

Hi,
I need general tips for solaris 11 performance optimization.
For example - disable the unused services, etc.
Thanks,

plimit
plimit(1) User Commands plimit(1)NAME
plimit - get or set the resource limits of running processes
SYNOPSIS
plimit [-km] pid...
plimit {-cdfnstv} soft,hard... pid...
DESCRIPTION
If one or more of the cdfnstv options is specified, plimit sets the soft (current) limit and/or the hard (maximum) limit of the indicated
resource(s) in the processes identified by the process-ID list, pid. Otherwise plimit reports the resource limits of the processes identi-
fied by the process-ID list, pid.
Only the owner of a process or the super-user is permitted either to get or to set the resource limits of a process. Only the super-user
can increase the hard limit.
OPTIONS
The following options are supported:
-k On output, show file sizes in kilobytes (1024 bytes) rather than in 512-byte blocks.
-m On output, show file and memory sizes in megabytes (1024*1024 bytes).
The remainder of the options are used to change specified resource limits. They each accept an argument of the form:
soft,hard
where soft specifies the soft (current) limit and hard specifies the hard (maximum) limit. If the hard limit is not specified, the comma
may be omitted. If the soft limit is an empty string, only the hard limit is set. Each limit is either the literal string unlimited, or a
number, with an optional scaling factor, as follows:
nk n kilobytes
nm n megabytes (minutes for CPU time)
nh n hours (for CPU time only)
mm:ss minutes and seconds (for CPU time only)
The soft limit cannot exceed the hard limit.
-c soft,hard Set core file size limits (default unit is 512-byte blocks).
-d soft,hard Set data segment (heap) size limits (default unit is kilobytes).
-f soft,hard Set file size limits (default unit is 512-byte blocks).
-n soft,hard Set file descriptor limits (no default unit).
-s soft,hard Set stack segment size limits (default unit is kilobytes).
-t soft,hard Set CPU time limits (default unit is seconds).
-v soft,hard Set virtual memory size limits (default unit is kilobytes).
OPERANDS
The following operands are supported.
pid Process ID list.
EXIT STATUS
plimit returns the exit value zero on success, non-zero on failure (such as no such process, permission denied, or invalid option).
FILES
/proc/pid/* process information and control files
