How can I increase size of /tmp directory

Hi All,

I am working with open solaris and in that I need to install one application which first put it's all files in /tmp directory and then place it in respective directory.but when i am trying to do it,it is giving the following message--

Quote:

Abc@opensolaris#. ./xyz.bin
Using /tmp for temporary storage.
bash: fork: Not enough space
bash: [: =: unary operator expected
Unpacking to /tmp/X.tar...
tail: cannot open input
Checksumming...
sum1=0
sumResults1=
sum2=0
sumResults2=
Unable to perform the installation. Either the distribution
file is corrupt or there is insufficient free space in /tmp.
This product requires free space at least 3 times the size
of the distribution file in /tmp. If that much is available,
please try downloading the file again.
Use 'bash <path>' to specify an alternate temporary directory.

So Please tell me how can I increase the size of /tmp directory in openSolaris.

Thanks in advance..

These lines are unexpected and the second indicates a script (or data) error

Code:

bash: fork: Not enough space
bash: [: =: unary operator expected

Are you really short of space in /tmp? What is the output from

Code:

df -h

output of df is as follows--

159 MB is small for /tmp so we can believe it is a genuine problem but it would be prudent to resolve the shellscript error, especially as you are presumably running this installation as root.

I don't know OpenSolaris so cannot safely advise how to enlarge /tmp. If there is an entry for /tmp in fstab then you may be able to comment out that line and have /tmp on / where you have lots of space. It is prudent not to have /tmp on / in case some badly-behaving program writes too much to it and fills it so you may want to back out any such change after using it for the installation.

An alternative if offered by "Use 'bash <path>' to specify an alternate temporary directory" but I do not understand what it is saying.

Long term it would be useful to increase the size of /tmp while keeping it somewhere other than /. Hopefully an OpenSolaris-spert will advise options for doing that.

Your program suggests (although it is poorly phrased) to use an alternate temporary directory so I would do it that way in your case.

Alternatively, if you want to increase /tmp size, you need to add a vdev dataset to your root zfs pool and add it as a swap device.

Code:

zfs create -V 1gb rpool/extraswap
swap -a /dev/zvol/dsk/rpool/extraswap
