You can have Linux, UNIX and Windows servers do tasks and runs scripts right from an i5/OS command line or a CL program. If you use CL, your program will even wait until the other sever completes its task before moving to the next instruction.
Use the RUNRMTCMD command and enter the foreign system command in the COMMAND parameter, the IP address or host name in the REMOTE LOCATION parameter, and indicate *IP for Type. Of course, you’ll also need a user name and password for the remote server.
The RUNRMTCMD will end and the next CL statement will execute when the command completes on the target system. If you want things to happen "asynchronously," use the COMMAND parameter to run a script on the foreign system that submits another job or spawns off another process. Just remember, whatever process you invoke on the target system has to finish before control returns to your CL. If the target system gets stuck, so does your program.
Using this command can also be a handy way to automatically perform functions when switching servers using the your high availability automation; you can trigger scripts that automatically change DNS, clear DNS cache, alter software configurations, and more.

7/17/09 How to find journaled files that are regularly cleared
If you are using a logical replication or high availability solution and you have certain files that are cleared on a regular basis, the following command can be used to identify those objects. If the file is cleared then it may be a file that does not need to be replicated, which will save you bandwidth in the replication process.

6/30/09 There's a backup version of the controlling subsystem (QCTL)
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 QSYS 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.
