If you’ve changed attributes of the QCTL subsystem and lost track of what the defaults should be, or worse yet you’ve changed the controlling subsystem in some way that the system refuses to IPL properly, there’s a little known “backup” version of the controlling subsystem called QSYSSBSD. It’s specially protected so that it cannot be changed, only displayed. It’s always there, in the QCTL library, waiting for you “just in case”.

6/19/09 How To Generate a Disk Analysis Report
Another way to see what is taking up your disk space is to view the i5/OS disk analysis report. To build the Disk Analysis file, use the following command:
SBMJOB CMD(RTVDSKINF) JOB(RTVDSKINF) JOBQ(QSYSNOMAX)
You can monitor the job by issuing the following:
WRKACTJOB SBS(QSYSWRK)
Job name = RTVDSKINF
Once the job finishes running, create the print report:
SBMJOB CMD(PRTDSKINF RPTTYPE(*LIB)) JOB(PRTDSKINF) JOBQ(QSYSNOMAX)
Other ways of seeing what is using disk space can be found on these two posts:

6/08/09 Create a Virtual Printer
Use the following steps to create a virtual printer that will print directly from an output queue to a network deskjet or laser printer.
- Start System i Navigator on your PC (If you do not have System i Navigator on your PC then it is possible to complete this task using CRTDEVPRT from a 5250 session)
- Select Basic operations, Printers.
- Right click and select Add Printer.
- Use the wizard and accept defaults, enter the IP address of the printer, enter your own name for the printer (not OfficeJet…).
- When wizard complete no need to print a test page as this will not print correctly anyway.
- Go on to a 5250 session and enter GO PRINTER
- Take Option 4 on the PRINTER menu
- Take Option 8 against the Printer Description created in step 4. For more information about this on the internet, go to the IBM information center using this link http://publib.boulder.ibm.com/iseries/. Search for the command “CHGDEVPRT” and you will find a list of printer manufacturers and models, lookup the Manufacturer and Model of your printer in the list of information and make a note of the value for MFRTYPMDL (e.g. *HP520 is the HP Deskjet 520.
- Return to the 5250 session and take Option 2, scroll down and change the setting for MFRTYPMDL to the value appropriate to your printer (e.g. *HP520).
You can now print directly to the Printer Description. You may need to first start the writer (GO PRINTER option 2 and option 1 against the appropriate printer).

5/29/09 Working with Spool files on System ASPs or iASPs
An output queue can be created in a library on an ASP or iASP. However, when using the WRKSPLF command you may not see the spool files that exist on the ASP/iASP unless you first set the iASP group using the command SETASPGRP (ASP/iASP Name).
Note to programmers: If you do programming with some iSeries APIs that retrieve information about spool files, it is not always necessary to specify the ASP/iASP name (unless, of course, you wish to). For example the API QUSLSPL will retrieve a list of spool files on *SYSBAS and on all available ASPs/iASPs without the need to use SETASPGRP; similarly QUSRSPLA will also retrieve spool file attributes without the need to use SETASPGRP.

5/19/09 How to see scheduled jobs in order of submission
When doing various system maintenance and management functions it is sometimes necessary to hold jobs on the Job Scheduler. Instead of using the command WRKJOBSCDE, which presents jobs alphabetically by name, use the command WRKJOBSCDE SEQ(*DATETIME). This will present the list of jobs in the order they are to be submitted, allowing you to quickly find those scheduled jobs that will occur during the timeframe of your system maintenance and management tasks.

5/8/09 How to execute a command on a remote system using FTP
Simply type the command as you normally would, but have it preceded by "QUOTE RCMD"
For example:
QUOTE RCMD CHKOBJ OBJ(QGPL) OBJTYPE(*LIB)
QUOTE RCMD CALL PGM(Yourpgm/Yourlib) PARM(Parms)

4/27/09 - How to delete a specifc relative record if the file is keyed
You can delete a specific relative record number when a file is keyed and the UPDDTA command can’t do it. Simply use normal OS/400 SQL and run the following:
delete from LIBRARY/FILENAME A where RRN(A) = 3
The above example deletes RRN number 3. Just replace LIBRARY and FILENAME with library and file names the ‘A’ after file name is needed. Then change the 3 at the end to be the actual RRN number you want to delete.
You may want to use a ‘select’ statement first to ensure you have the right record, here’s an example of that:
select * from LIBRARY/FILENAME A where RRN(A) = 3
