If you are having trouble booting aix, you can open verbose mode by doing following things:

While booting system pres1 button for “open firmware”. On firmware prompt;

1. For AIX 5.3 and greater, use: 
   At the 0> prompt, enter “boot -s verbose”
   0> boot -s verbose
   
2. For AIX 5.2 or earlier use: 
   At the 0> prompt, enter “boot -s trap”
   0> boot -s trap
   

Linux

Umount -l /fs

 AIX

Fuser -xuck /fs

Umount -f /fs

Tar command normally have ability to uncompress z files. But in aix it is not available. We have a solution for aix.

To compress:

“tar cvf – abc | gzip > abc.tar.gz”

“tar cvf – abc | bzip2 > abc.tar.bz2″

To uncompress:

“gunzip < abc.tar.gz | tar xvf -”

 ”bzip2 < abc.tar.bz2 | tar xvf -”

(you can remove “v” option for faster process, because “v” means verbose)

To check the SAG version , please issue the command by SAG Admin ID:

1. Change to the installation directory of your SAG (for example c:\SWIFT\SNL\SwiftNet\bin on Windows system).
   
2. Issue swiftnet version -a to get the version .

# diff cookies.old cookies.new
5c5
< One cup vanilla extract
—
> One teaspoon vanilla extract
7d6
< Six ounces chopped liver
21a22
> Note: The previous version of this recipe had a few errors!

The output is actually a description of how to transform the old file into the new one. Here, diff is telling you three things:

1. The fifth line of the file has undergone a change. The 5c5 message says to replace line 5 of the old file with line 5 of the new file. Both the old and new text are displayed, separated by a line of three dashes. (The less-than (<) notation means “remove this line,” and the greater-than (>) sign means “add this line.”)
   
2. Line 7 of the old file does not appear in the new file. The 7d6 message says to delete line 7 from the old file, and the files will then be in sync, starting at line 6 of the new file. The text to be deleted is displayed on the next line.
   
3. A line was added to the new file. The 21a22 message says to add a new line after line 21 of the old file. The text to be added is displayed on the final line of the output.

Update the system’s argument length fixes that…

On Solaris 10, IPv4 addresses are looked up in /etc/inet/ipnodes before /etc/inet/hosts.

From /etc/nsswitch.dns:

# Note that IPv4 addresses are searched for in all of the ipnodes databases
# before searching the hosts databases.

This means that if you have the following in /etc/nsswitch.conf (which is the default from /etc/nsswitch.dns)

ipnodes:    files dns
hosts:      files dns

the IPv4 resolution order will be:

1. /etc/inet/ipnodes
2. DNS (name servers in /etc/resolv.conf)
3. /etc/hosts
4. DNS (name servers in /etc/resolv.conf)

This may confuse administrators accustomed to placing IPv4 addresses in /etc/hosts to override resource records in DNS.

The easiest way to check /etc/inet/ipnodes and /etc/hosts before DNS is to remove dns from the /etc/nsswitch.conf ipnodes: entry.

ipnodes:    files
hosts:      files dns

The IPv4 resolution order will be:

1. /etc/inet/ipnodes
2. /etc/hosts
3. DNS (name servers in /etc/resolv.conf)

Procedure

• Create the file in /dev/lpx. Enter the following sequence of commands:
  
•     cat /dev/null > /dev/capture
  
•     chgrp printq /dev/capture
  
•     chmod 777 /dev/capture
  
• To create the queue, do the following:
  
  • Enter smit mkpq.
    
  • Choose:
    
  •  File     File (in /dev directory)
    
  • Choose the manufacturer of the selected printer.
    
  • Choose the printer model.
    
  • Name of existing FILE in /dev
    
  • directory        capture
    
  • Enter queue names for various emulations and press Enter or DO.
    
• Print to the file. Enter:
  

  echo “AAAAA” | qprt -Pqueue_name    (This is easy to find in the capture file.)
  

  qprt -P<queue> <filename>
  

• View the results and complete the following steps:
  
  • Enter cat -v /dev/capture.
    
  • To see the results, enter vi /dev/capture.
    
  • To identify control characters, enter od -ca /dev/capture.
    
• To rezero the capture file, enter:
  

  cat /dev/null > /dev/capture’
