I need to know what does 0.0% swap means. As swap being used is high in the case above compared to free, does that affects the performance of the system as other systems show lower swap in use but there also its like 0.0% swap.
Hi there,
I´m trying to get the information of vmstat & top in two different logfiles.
That not that difficult.
vmstat 30 >> myfile.log
top >> myfile2.log
But I also like to include a timestamp every 30 sec to be sure from what date the logs are.
For the Top command I were able to... (2 Replies)
Hi Guru's,
Since Iam learning Solaris 10 and want to instal it on to my computer in which 'Windows' is already installed. Also many other applications including Oracle, Java etc,. were also installed associated with Windows.
Now how can I install Solaris 10 on my system with out affecting my... (4 Replies)
Hi folks,
Sorry to barge in and ask a question right off the bat without contributing first.
I have a V440, 4 X 1GHZ, 32GB ram, and recently syslogd has started showing 30+ % cpu usage. It's also repeating entries in the syslog, over and over.
the /var/log/syslog file had grown to over 2GB - I... (2 Replies)
I am changing jobs and need to know a little about Solaris specific commands. I come from AIX and we have commands like errpt, smit, and lsattr that are AIX specific.
Any help is appreciated. (4 Replies)
Hi all,
I have a server running an Oracle database that is part of a Solaris M5000 container. Presumably this is referred to as a zone within a cluster, not sure if I get the terminology right.
Anyway, a third-party manages the zone and unfortunately is not "helpful/friendly" to assist me on... (1 Reply)

Hello Guru's
I'm trying to take the output of solaris top command and output to a txt file every few minutes. The issue that I'm experiencing is that I can run the following:

Hi guys,
I got an issue today with one of my servers. The guy is reporting by top only 1.8 available Gig for physical memory.
I see my processes and they don't even get to 15Gigs, I have 64 physical Gigs.
Details
Memory: 64G phys mem, 1820M free mem, 32G total swap, 32G free swap
I have... (4 Replies)

allocate_fs_swapmap
allocate_fs_swapmap(5) File Formats Manual allocate_fs_swapmap(5)NAME
allocate_fs_swapmap - determines when swapmap structures are allocated for filesystem swap
VALUES
Failsafe
Default
Allowed values
or
DESCRIPTION
The tunable is used to determine whether to allocate all needed filesystem swap structures during the initialization of the filesystem swap
device or wait until they are needed. Pre-allocation of all filesystem swap structures upon initialization saves time during later usage
of the filesystem swap, and prevents later allocation failure due to physical memory contention.
Dynamic allocation decreases the memory footprint of the filesystem swap system.
Who is Expected to Change This Tunable?
Anyone.
Restrictions on Changing
Changes to this tunable take effect at the next reboot.
When Should the Value of This Tunable Be Raised?
Systems under heavy memory load may not be able to acquire enough memory to hold the swap mapping structures for an addition of file system
swap. These calls to add swap would fail with the error though presumably they would be retried. Frequent failure on file system swap
addition with would merit enabling this tunable.
What Are the Side Effects of Raising the Value?
All the swap map structures for each file system swap device would be preallocated during swap initialization at kernel boot, increasing
the memory footprint of the kernel. The amount of increase depends on the number and size of file system swap devices.
When Should the Value of This Tunable Be Lowered?
Systems with limited memory available to the kernel that also have limited use of file system swap devices should disable this tunable to
decrease kernel memory usage.
What Are the Side Effects of Lowering the Value?
File system swap additions may fail with when memory contention is high.
What Other Tunable Values Should Be Changed at the Same Time?
None.

Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation,
some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun-
