Chapter 9

1.  Operating System, Licensed Program Products, and PTFs



2.  IBM Software

	*Four main types:

		-The operating system, OS/400. 

		-Optional Licensed Program Products (LPPs). 

		-Optional Programming Request for Price Quotations (PRPQs). 

		-Program Temporary Fixes (PTFs). 



3.  Operating System – OS/400

	*Basic functions

	*Multi-user

	*Multi-tasking

	*DB2/400

	*Industry's highest-level security

	*Network and communication support

	*Serve PC and UNIX files

	*Program scheduling



4.  Operating System Major Functions

	*Running more than one program at a time concurrently.

		-Scheduled

		-Active vs. Inactive

		-Priority

	*Handling printed output (spooling).

	*Scheduling work on the system.

	*Communicating with the user.



5.  Concurrent Processing

	*Jobs are allocated the following:

		-Computer processor

		-Main storage

		-I/O devices

		-Data resources



6.  Running Programs/jobs

	*A program or series of programs can be scheduled. 

	*Series of programs run concurrently and/or sequentially. 

	*Programs waiting - low priority. 

	*Programs running - high priority. 

	*Programs inactive due waiting for resources. 



7.  OS/400 Versions

	*Version

	*Release

	*Modification

	*Called "Release Level"

	*For Example:

		-V4R4M0

11.  Ordering Software

	*The new release of the operating system, comes with:

		-OS/400.

		-All current PTFs for new OS/400. 

		-Licensed product program(s).

		-All current PTFs for licensed program(s).

		-RPRQs and all current PTFs for them.



12.  Installation Guide Determines

	*Length of installation. 

	*Schedule work load. 

	*Predict two things: 

		-Additional disk space. 

		-Speed of AS/400 after new release. 



13.  Pre-installation Process

	*Cleaning up the system:

		-Test files. 

		-Libraries for vendor demos. 

		-Old system logs.

	*PTFs needed before new release.

14.   *Multiple AS/400 connects on a network, check interoperability.

	*Make 2 complete backups.

		-Include changed objects in Q libraries. 

	* Verify users QSECOFR and QLPINSTL in system directory (DSPDIRE). 



15.  Display Directory Entries

16.  Licensed Program Products (LPP)

	*Examples of LPPs are:

		-Client Access/400 

		-All program compilers (Languages) 

		-Query products 

		-Office Vision/400 

		-Application Development Toolset 

		-Advanced backup/recovery tools

19.  Programming Request for Price Quotations (PRPQs) 

	*PRPQs are smaller 

	*Single-function programs 

	*Not "supported" by IBM 



20.  Program Temporary Fix -PTFs 

	*PTFs installed permanent or temporary.

	*Not just installed rather loaded, then applied. 

		-Applied permanent or temporary. 

		-Delayed or immediate. 



21.  Two Types of PTFs

	*Normal

	*High-impact pervasive PTFs (HIPER)

	*DSPPTF 5769999   	-	LIC

	*DSPPTF 5769SS1   	-  	OS/400

	*DSPPTF 5769CB1		-	COBOL

28.  PTF Status - Continued

	SEE TABLE()



29.  Order PTF

	*ECS (Electronic Customer Service) 

	*Cover letter placed in file QAPZCOVER (library QGPL) 

	*Member named with P followed by PTF number 

30.   *Display Physical File Member (DSPPFM) command  

	*Print with Copy File (CPYF) command specifies OFILE(QSYSPRT) 

	*HIPERs through Internet at  http://www.as400service.ibm.com 



31.  Ordering

	*You can order PTFs through: 

		-On AS/400 through ECS modem - Send PTF 

             Order (SNDPTFORD) command. 

		-Your marketing representative 

		-Call AS/400 Service 

		-Internet at: http://www.as400service.IBM.com 



32.  Send PTF Order

	SEE TABLE()



33.  Special PTF Numbers

	-v is the OS/400 version number 

	-r is the release number 

	-m is the modification level 



34.  Reserved PTFs

35.  Contact Information Screen

36.  Verification Screen

37.  PTF Installation

	*PTFs must be loaded then applied to make active.  

	*ECS-delivered PTFs are "loaded." 

	*Read the cover letter. 

	*Follow any instructions. 



38.  Before Applying Any PTFs

	*Do the following:

		-Make a backup of your system -  SAVSYS command. 

		-All users sign off the AS/400. 

		-Sign on with SECOFR authority. 



39.  Two PTF Install Operations

	*Load PTF (LODPTF). 

	*Apply PTF (APYPTF). 



40.  Load PTF

	SEE TABLE()



41.  Applying PTFs

	*PTFs are applied in two conditions:

		 -Temporary: 

			-Takes a little longer when they run. 

			-Can be removed in the future. 

		-Permanent: 

			-Becomes a permanent part of the program product. 

			-Runs fast. 

			-Cannot be removed. 



42.  Further Two PTFs Types 

	*Immediate—Once applied, take effect immediately. 

	*Delayed—Once applied,  do not take effect until after the next IPL. 



43.  Apply PTF

	SEE TABLE()



44.  Applying PTFs Permanently

	*PTFs are applied temporarily by default. 

	*System keeps two versions of system objects:

		-Old one is in IPL storage area A. 

		-New one is in area B 



45.  Removing PTFs

	*Only PTFs not applied permanently can be removed. 

	*PTF removal. 

		-Temporarily 

		-Permanently
