    1. 1 Chapter 9 Operating System, Licensed Program Products, and PTFs

    2. Understanding AS/400 System Operations 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. Understanding AS/400 System Operations 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. Understanding AS/400 System Operations 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. Understanding AS/400 System Operations 5 Concurrent Processing Jobs are allocated the following: Computer processor Main storage I/O devices Data resources In concurrent processing it appears as though multiple jobs are processing at the same time. Jobs enter the system from job queues. Jobs move between various resources while processing. Jobs when moving between resources queue up to obtain resource. For example: Job waits on CPU Gets access to CPU Processes until it reaches the end of it time slice or requires other resources (example: data records.) Job moves to I/O queue waiting to access disk and data. When job move from CPU another job accesses CPU. When initial job has records it returns to CPU queue. Etc. Various resources have queues and a job can be active on each resource at a time. Thus, multiple jobs are processing in different stages of processing at the same time but no jobs are doing the same process at the same time. Really only 1 process is active in one resource at the same time. In concurrent processing it appears as though multiple jobs are processing at the same time. Jobs enter the system from job queues.

Really only 1 process is active in one resource at the same time.

    6. Understanding AS/400 System Operations 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. Understanding AS/400 System Operations 7 OS/400 Versions Version Release Modification Called “Release Level” For Example: V4R4M0

    8. Understanding AS/400 System Operations 8 Licensed Program Menu Figure 9-1: Sample of the LICPGM menu. Access with following command: GO LICPGM Option 1 – Installs all software from shipped media. Option 5 – new with V4R1 – An automated process that checks your system in preparation of the new installation. Estimates space requirement, software compatibility, supported etc. Option 10 – Shows what licensed programs installed and their release level. Option 11 – Allows you to select which Licensed programs you want to install. Can install a single product or a component of a product.Figure 9-1: Sample of the LICPGM menu.

    11. Understanding AS/400 System Operations 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. Understanding AS/400 System Operations 12 Installation Guide Determines Length of installation. Schedule work load. Predict two things: Additional disk space. Speed of AS/400 after new release.

    13. Understanding AS/400 System Operations 13 Pre-installation Process Cleaning up the system: Test files. Libraries for vendor demos. Old system logs. PTFs needed before new release.

    14. Understanding AS/400 System Operations 14 Pre-installation Process 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).

    29. Understanding AS/400 System Operations 29 Order PTF ECS (Electronic Customer Service) Cover letter placed in file QAPZCOVER (library QGPL) Member named with P followed by PTF number

    30. Understanding AS/400 System Operations 30 Order PTF - Continued 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. Understanding AS/400 System Operations 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.IBM.com/servers/eserver/support/iseries

    32. Understanding AS/400 System Operations 32 Send PTF Order Figure 9-13: Sample screen to send a PTF order.Figure 9-13: Sample screen to send a PTF order.

    33. Understanding AS/400 System Operations 33 Special PTF Numbers v is the OS/400 version number r is the release number m is the modification level

    34. Understanding AS/400 System Operations 34 Reserved PTFs Figure 9-14: Reserved PTF numbers. If possible demonstrate using SNDPTFORD to receive an informational PTF. Go over the information received.Figure 9-14: Reserved PTF numbers. If possible demonstrate using SNDPTFORD to receive an informational PTF. Go over the information received.

    35. Understanding AS/400 System Operations 35 To retrieve a PTF from the Web Go to the URL on previous slide Enter then PTF number or the reserved PTF number For Example: to retrieve cumulative PTF enter SF97530 Where SF97 means cumulative PTF and 530 is for V5R3M0

    36. Understanding AS/400 System Operations 36 Retreive PTF through iSeries Use SNDPTF command iSeries must have a modem connected Complete information as shown in the next slides

    37. Understanding AS/400 System Operations 37 Contact Information Screen Figure 9-15: Shipping and contract information change after SNDPTFORD.Figure 9-15: Shipping and contract information change after SNDPTFORD.

    38. Understanding AS/400 System Operations 38 Verification Screen Figure 9-16: Verification screen before the order is sent.Figure 9-16: Verification screen before the order is sent.

    39. Understanding AS/400 System Operations 39 PTF Installation PTFs must be loaded then applied to make active. ECS-delivered PTFs are “loaded.” Read the cover letter. Follow any instructions.

    40. Understanding AS/400 System Operations 40 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.

    41. Understanding AS/400 System Operations 41 Two PTF Install Operations Load PTF (LODPTF). Apply PTF (APYPTF).

    42. Understanding AS/400 System Operations 42 Load PTF Figure 9-17: The prompted version of command LODPTF.Figure 9-17: The prompted version of command LODPTF.

    43. Understanding AS/400 System Operations 43 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.

    44. Understanding AS/400 System Operations 44 Further Two PTFs Types Immediate—Once applied, take effect immediately. Delayed—Once applied, do not take effect until after the next IPL.

    45. Understanding AS/400 System Operations 45 Apply PTF Figure 9-18: Command APYPTF after supplying the product code. Figure 9-18: Command APYPTF after supplying the product code.

    46. Understanding AS/400 System Operations 46 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 A is the Permanent side. B is the Temporary side.A is the Permanent side. B is the Temporary side.

    47. Understanding AS/400 System Operations 47 Removing PTFs Only PTFs not applied permanently can be removed. PTF removal. Temporarily Permanently
