I just finished installing Solaris 2.6 and several applications just to realize that I made a bonehead mistake during the install. When setting up the filesystems, I entered /tmp and no swap! Is it possible to permanantly declare the entire /tmp partition as swap? I am guessing an entry in the... (4 Replies)
Hi,
I have a solaris 9-sparc box, which after bouncing is giving swap space related error messages(that swap space is not enough). could it be possible that there was some command issued or setting made before bouncing, which was lost after bouncing? please let me know how i can add swap space...

Hi Guys !
I have found this problem many times that the swap space (/tmp space more precisely )of my Server becomes full specially when i run a complete back up of the server .
once the /tmp space is full I am not able to run simple commands as i get error like :
fork no space

We have a SPARC system which is running on Solaris-9 and Physical memory size is 16GB.We have allocated 32GB SWAP space(2 times of physical memory).But when we use df -h command it shows following output and SWAP space size shows more than our allocated space
# df -h
Filesystem size used... (2 Replies)
Hello Team,
By the way of introduction, I am new member in this forum and proud too :)
Here is my questions:
In one of our Solaris Sparc v9 box, we are facing issues related to swap space. Our custom applications are using swap space even though physical memory is available.
From some... (3 Replies)
Hello,
Ive got a bunch of numbers here e.g:
6065
6094
6348
6297
6161
6377
6338
6290
How do I find out if there is a difference between 10% or more between one of these numbers ? I am trying to do this in Bash.. but no luck so far.. Does anyone have an Idea ??
Thanx,

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.
