swinstall analysis

[Daedalus_1]

Hi

I've downloaded a script (see attachment) from HP which is used to generate depot base on patch files. It call some commands like swcopy, swpackage which will make use of "/tmp".

However, my machine got around 65Mb /tmp disk space only.

Is there any other get-around?


Thank & regards

Hi Daedalus,

The script does not use /tmp but $PWD = current dir for files, so if you move the tree to an other place you can execute the script there. The depot will be created in $PWD/depot.

Hi,
This srcipt creates depot for you in the directory where you are. Now what you do is use "bdf" command to look out for space and Switch yourself to the convenient directory and execute this script.
Hope that helps.

However, when I run the script when temp has only 35MB(the directory where i extract the depot has more than 1 GB disk space). The following error message appeared.

/*****************************************

The default location for depots is /var/adm/sw. It's probably a good idea to set this up as a separate filesystem in its own logical volume so it doesn't fill /var.

Once you've done this:

cd /var/adm/sw

then run the script.

Hi Daedalus,

I noticed that in your script may be is missing the following line:

SD_LIST=

After:

#
# Temporary values
#
PID=$$
#PSF=depot$PID.psf
PSF=depot.psf

## HERE:
SD_LIST=

#
# Upon exit...
#
#trap 'rm -f $PSF; exit' 0 1 2 15

Hope this will help!

Regards,

Eric

Some more new findings on the problem.

I found where exactly in the script promp out error message. It is when the script running the PHSS_* files by calling a shell.

(e.g>/bin/sh PHSS_XXXXX)

Which patch files will result on error? It depends on how much /tmp size we got. When there's around 50 MB. Only running PHSS_26945 will result error.


Here's a example when I run the line on the command prompt alone.

when only 50MB in /tmp

Hi Daedalus,

If you don't specify the -d option with the script, then it will create the depot in the current working directory. So, find out a filesystem where you have enough space (say /apps1 ) and then specify it with the script. For ex.,

./create_depot -d /apps1/depot

It will create the depot at /apps1/depot location. Find it out by issuing the command

'swlist -l depot'.

I think this error occurs because unsharing of the patch file (sh PHSS_26945) creates some temporary files in /tmp.

Towards the end of PHSS_26945 file, there are following two lines.

uncompress /tmp/compress$$
mv /tmp/compress$$ PHSS_26945.depot

This temporary file (compress$$) is probably too big for /tmp and therefore you are getting the error.

You can use the following awk script to replace references to /tmp with TMPDIR.

$ cat addTMPDIR.awk
/..@EOF/ {scan_off=1}
/^@EOF/i {scan_off=0}
/unpacker <<.@eof./ {scan_off=1}
{
if(scan_off != 1) {
gsub ("/tmp", "$TMPDIR")
}
print $0
}

$ cp PHSS_26945 PHSS_26945.orig
$ awk -f addTMPDIR.awk PHSS_26945.orig > PHSS_26945

Repeat this procedure for every patch that's causing the problem.

Before you run the script to create the depot again make sure you define TMPDIR to a directory with sufficient free space.

$ export TMPDIR=
