How to clear pending/stuck print job in AIX

## In this scenario the print queue name/printer name is AV169. This is for SAP printing. Check whether the print queue name/printer name is exist or not and it is pingable or not. If everything is fine, then proceed with the 3 steps below


1) root@sap03_R3P / # disable AV169
** This command will disable the printer for a while


2) root@sap03_R3P / # qcan -x 23 -P AV169
** Look for the first print queue ID that is listed. In this case the first print queue ID is 23

root@pxipvsap03_R3P / # lpstat -oAV169

** Enter the command above to remove that print queue. After that, enter command : lpstat -oAV169 | more . If that print queue is still exist repeat the above command until that print queue is remove and disappear from the list. Then, enter again command lpstat -oAV169 | more for confirmation.


3) root@sap03_R3P / # enable AV169
** To enable again the printer, type the above command.


Follow the below steps for how to :)

** The bdf command displays the amount of free disk space available


To check physical volume of disk, type ioscan -funC disk

** Ioscan scans system hardware, usable I/O system devices, or kernel I/O system data structures as appropriate, and lists the results.



To check further information of physical volume type, pvdisplay /Physical/volumes/path

** pvdisplay - display information about physical volumes within LVM volume group


To check Volume Group (VG), look at the output of the bdf command and see at the Filesystem field, /dev/vg00 <-- vg00 is the Volume Group (VG). Then type command, vgdisplay

volumegr0up [hpa50-12]/ >vgdisplay vg00

To scan the existing volume group, type vgscan

[hpa50-12]/ >vgscan
vgscan: The physical volume "/dev/dsk/c1t15d0" is already recorded in the

"/etc/lvmtab" file.
Physical Volume "/dev/dsk/c3t15d0" contains no LVM information

** vgdisplay - display information about LVM volume groups



To check Logical Volume, look at the output of the bdf command and see at the Filesystem field, /dev/vg00/lvol3, /dev/vg00/lvol1 and /dev/vg00/lvol8. lvol3, lvol1 and lvol8 are the logical volume. To getthe information of logical volume type, lvdisplay /dev/vg00/logicalVolume

Use Variables with Scripts

Using an editor or the cat command, write a script that uses a variable. Note that this script uses the bash shell on LINUX, but you can also use the ksh shell with UNIX.


1) Set a value for the variable first using typeset then check it using set.

[root@vmpc_rh804 root]# typeset first=you
[root@vmpc_rh804 root]# set | more
BASH=/bin/bash
BASH_ENV=/root/.bashrc
BASH_VERSINFO=([0]="2" [1]="05b" [2]="0" [3]="1" [4]="release" [5]="i686-pc-linu
x-gnu")
BASH_VERSION='2.05b.0(1)-release'
COLORS=/etc/DIR_COLORS
.
.
.
first=you
hi=hello
langfile=/root/.i18n


2) Write a short Welcome script that uses a variable.

[root@vmpc_rh804 root]# cat > Welcome.bash
#!/bin/bash
#
first=Student
echo "Welcome to Linux $first"
Ctrl/D


3) Execute your script using the shell interpreter.

$ bash Welcome.bash
Welcome to Linux Student

Invoke a Script

Use various methods to invoke a script, and determine when it runs in your shell, and when a subshell is created.


1) Using an editor or the cat command, write a korn or bash script that:
* Executes the ps command.
* Echos the value of the shell variable hi.

[root@vmpc_rh804 root]# cat > do-ps.bash
#!/bin/bash
# This script displays active processes
#
ps
echo $hi


2) Set the value of hi to hello in your current command line shell.

[root@vmpc_rh804 root]# hi=hello


3) Execute your script using the shell interpreter.

[root@vmpc_rh804 root]# bash do-ps.bash
PID TTY TIME CMD
1311 pts/4 00:00:00 bash
1358 pts/4 00:00:00 bash
1365 pts/4 00:00:00 ps

** Note that it doesn't recognize the hi variable. This is because the variable is local to the shell in which it was defined. When this script is executed, a new shell is started that is outside your local shell. **


4) Add execute privilege to the script file and run it as a command from the current directory.

[root@vmpc_rh804 root]# chmod +x do-ps.bash
[root@vmpc_rh804 root]# ./do-ps.bash
PID TTY TIME CMD
1311 pts/4 00:00:00 bash
1367 pts/4 00:00:00 do-ps.bash
1374 pts/4 00:00:00 ps


5) Use the built-in source command to execute the commands in the script file.

[root@vmpc_rh804 root]# source do-ps.bash
PID TTY TIME CMD
1311 pts/4 00:00:00 bash
1375 pts/4 00:00:00 ps
hello
[root@vmpc_rh804 root]#


** Note that it is able to recognize the hi variable. This is because the source command runs this script in the local shell. **
