1. How to make job list activate an Aleph service twice a month or once a month
Yoel Kortick

2. Introduction
The Aleph job_list from $alephe_tab is designed to work on a weekly basis.
It is possible to have the job_list activate a secondary script which will then run the job on either a “every other week” or “once a month“ basis.
There are many ways to do this, and here we will show only one way for each frequency.

3. Run the job and get parameters
The first step is to run the desired Aleph service once from GUI and then get desired parameters from $alephe_scratch log file
Here we run ret-03

4. Run the job and get parameters
Here we get the parameters of the job ret-03
il-aleph02-19(4) USM50-YOELK>>cd $alephe_scratch
il-aleph02-19(4) USM50-YOELK>>grep ^start usm01_p_ret_
start USM01,wti_library,wti=library,
Here we make a simple script which includes a line to run the job (we will soon edit this script)
il-aleph02-19(4) USM50-YOELK>>cat /exlibris/users/yoelk/aleph_op_p_ret_03_main
csh -f $aleph_proc/p_ret_03 USM01,wti_library,wti=library, > $alephe_scratch/p_ret_03.log.`date '+%Y%m%d.%H%M%S'`

5. Twice a month - Make variable
Now we will make a second script which will contain a variable which will start as “Y” but, as we will see, change back and forth between Y and N every time the job is run. Here is the starting situation of the script.
il-aleph02-19(4) USM30-YOELK>>cat /exlibris/users/yoelk/aleph_op_p_ret_03_variable
set ran_previous_time = Y
If source is done on this file then a parameter will be created “ran_previous_time”

6. Run the job depending on variable
Now we will edit the first script as follows:
If the variable “ran_previous_time” = Y then the job will not run, and will change the file “aleph_op_p_ret_03_variable” so that next time “aleph_op_p_ret_03_main” is run the variable will be “N”
If the variable “ran_previous_time” = N then the job will run, and will change the file “aleph_op_p_ret_03_variable” so that next time “aleph_op_p_ret_03_main” is run the variable will be “Y”

7. Run the job depending on variable
il-aleph02-19(4) USM30-YOELK>>cat /exlibris/users/yoelk/aleph_op_p_ret_03_main
source /exlibris/users/yoelk/aleph_op_p_ret_03_variable
if ($ran_previous_time == "Y") then
echo "ran_previous_time" is $ran_previous_time
echo "job not running because it ran last time"
perl -pi -e 's/Y/N/' /exlibris/users/yoelk/aleph_op_p_ret_03_variable
endif
if ($ran_previous_time == "N") then
echo "job running because it did not run last time"
csh -f $aleph_proc/p_ret_03 USM01,wti_library,wti=library, > $alephe_scratch/p_ret_03.log.`date '+%Y%m%d.%H%M%S'`
perl -pi -e 's/N/Y/' /exlibris/users/yoelk/aleph_op_p_ret_03_variable

8. Testing the script
Now if we run the script then the first time it should not run p_ret_03 and the second time it should run p_ret_03
the third time it should not run p_ret_03 and the fourth time it should run p_ret_03
This will continue indefinitely

9. Testing the script Did not run Did run Did not run Did run
il-aleph02-19(4) USM30-YOELK>>csh -f /exlibris/users/yoelk/aleph_op_p_ret_03_main
ran_previous_time is Y
job not running because it ran last time
il-aleph02-19(4) USM30-YOELK>>
ran_previous_time is N
job running because it did not run last time
Did not run
Did run
Did not run
Did run

10. Adding the script to job_list
Now all that is left to do is add the script to $alephe_tab/job_list for once a week.
One week the script will run the ret_03 and the next week it will not. !
!!-!!!!!!!!-!-!!!!!!!!!!!!!!!!!!!!-!!!!!-!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!-!!!!!!
00 06:00:00 N ret_03.log csh -f /exlibris/users/yoelk/aleph_op_p_ret_03_main

11. Script for once a month
Now we will make a script which will run p_ret_03 once a month, on a particular date every month
The script will first check the date of the month and
If it is a particular predefined date then ret_03 will run.
If it is not a particular predefined date then ret_03 will not run.

12. Script for once a month There are many date options in UNIX
The command man date will show them all
We will use date '+%d' which shows the numeric date of the month
il-aleph02-19(4) USM30-YOELK>>date '+%d' 13

13. Script for once a month
Here is the script as set to run only if the date is the 04th of the month:
il-aleph02-19(4) USM30-YOELK>>cat /exlibris/users/yoelk/aleph_op_p_ret_03_once_a_month
set day_of_month = "`date '+%d'`"
if ($day_of_month == "04") then
echo "Today's date is" $day_of_month
echo "p_ret_03 will run"
csh -f $aleph_proc/p_ret_03 USM01,wti_library,wti=library, > $alephe_scratch/p_ret_03.log.`date '+%Y%m%d.%H%M%S'`
else
echo "Today is not the 04th of the month, p_ret_03 will not run"
endif
When date is 04 script will run
When date is not 04 script will not run

14. Script for once a month
Here is what happens when the date is not the 04th of the month:
il-aleph02-19(4) USM30-YOELK>>csh -f /exlibris/users/yoelk/aleph_op_p_ret_03_once_a_month Today's date is 13 Today is not the 04th of the month, p_ret_03 will not run
Here is what happens when the date is the 04th of the month:
il-aleph02-19(4) USM30-YOELK>>csh -f /exlibris/users/yoelk/aleph_op_p_ret_03_once_a_month Today's date is 04 p_ret_03 will run il-aleph02-19(4) USM30-YOELK>> il-aleph02-19(4) USM30-YOELK>>cd $alephe_scratch il-aleph02-19(4) USM30-YOELK>>ls -lrt | tail -1 -rw-rw-r aleph exlibris Jan 04 13:02 p_ret_03.log

15. Script for once a month
Now all we have to do is add this to job list to run every day.
When it is the fourth of the month is will activate ret_03, and when it is not the fourth of the month it will not activate ret_03. !
