Assistance Levels

  • Determines how much information is displayed and how it is formatted.

  • Basic, Intermediate, Advanced, default on USRPRF

  • Page 20, 81-91 in text.

  • Try it out for yourself using the WRKSPLF command and function key F21


AS/400 finds Objects

Note: Library Descriptions, Device Descriptions and User Profiles are systems objects and thus stored in QSYS.

All other Object Types can be stored anywhere else

Except for a ?????????.


Security on the as 400
Security on the AS/400

  • EDiTOBJect AUThority command

  • See pages 22-25, 31-36 for more Details

  • Need authority to the Library and then to the object


For some system specific values use dspsysval with qmodel qsrlnbr etc
For some System specific values useDSPSYSVALwithQMODELQSRLNBRETC.


WHY ?

BACKUP


Backups and restores
Backups and Restores

  • Data may be lost for a variety of reasons and therefore you should be prepared (if necessary) to:

    • restore the entire system

    • restore security data, configuration objects, licensed programs libraries

    • restore any library or any object

    • restore any or all members of a file


Disaster planning
Disaster Planning

  • A disaster plan should be well thought out and well documented.

  • A typical BACKUP plan might be to dofull backups once per week and only backup changes on a daily basis.

  • A RESTORE plan for this scenario would involve Step 1: restoring from the full backupStep 2: restoring from each of the changes backup to the time period desired.

BACKUP

  • Tape or Savefile

  • All or Changes Only

  • Can be done while people are working

    RESTORE

  • Restore the most recent ALL backups of all libraries

  • Restore all of the CHANGES ONLY backups since the last ALL backup

    REBOOT - IPL


When to back up?

Break the procedure up into manageable and practical lots and based on realistic and secure implementation.

System - when it changes

new release

PTF’s

Configuration - -when it changes

devices added

network changed

Libraries - when updates received

IBM licensed products

Security data - new users / reassignments

user profiles

authorizations

OBJECTS - SAVCHGOBJ

DAILY when changed


Create

A

BACKUP plan

For

Daily

Weekly

Monthly

Quarterly

requirements

A dependable backup plan MUST ensure that EVERY object and category

of object has been and is saved on a regular basis.


BACKUP MEDIA

TAPE - DISKETTE - SAVF

Before use initialize

INZTAP - INZDKT

To see the contents

DSPTAP - DSPDKT - DSPSAVF

or use the menu’s

GO TAPE - GO DISKETTE - GO SAVE


Saving data backups
Saving Data (backups)

  • Go Save (menu)

  • Data can be saved to tape, diskette or a savefile.

  • Commands: savsys, savlib, savsecdta, savobj, savchgobj, inztap, inzdkt

    • SAVSYS saves QSYS, licensed programs, security data, configuration objects

    • inztap and inzdkt are like the DOS “format” command


Some Save Commands

  • SAVSTG - saves every object on the system

  • SAVSYS - saves LIC, OS, and all security data

  • SAVSECDAT - saves all security data e.g USRPRF AUTL

  • SAVDLO - saves Document Library Objects

  • SAVLIB - saves “named” libraries

  • SAVCFG - save configuration (devices / lines / controllers +

  • SAVCHGOBJ - saves objects changed since last save function

  • SAV - can save the entire system - recommended for IFS only

    • Integrated File System

It is best to run backup with *SAVSYS authority

For saving *SAVF files to tape you use the

SAVSAVFDTA command

A *SAVF must first be created using the

CRTSAVF command before it can be used

You can think of this as setting a part of the

DASD (direct access storage device) aside and “initializing it”

You can save any object to a save file. E.g. libraries, data files (generic grouping etc


Reclaim storage

RCLSTG recovers all space in use by “FREE” objects

objects with no library reference or not owned by ANY user

! TIME !

Clean up

Remove objects that are no longer required

Clear

libraries - CLRLIB

large dormant files - CLRPF

leaves structures untouched


Preparatory Steps for a backup

Initialize the media

do cleanup tasks

reclaim storage

GO ASSIST or GO SETUP

BACKUP tasks

set up automatic scheduling

! *SAVSYS, Restrict access, notify everybody ‘SNDBRKMSG’

ENDSBS except QCTL

run the backup


Restoring data
Restoring Data

  • Restore commands use saved data from backups to replace damaged or deleted objects.

  • GO RESTORE - GO CMDSAV

  • Commands: RSTLIB, RSTOBJ, RSTCFG, RSTUSRPRF, RSTAUT



Menu functions

GO

CLEANUP - SCHEDULE, CHANGE , START CLEAN UP TASKS

BACKUP - RUN, DISPLAY STATUS, SET UP, INZ???

SETUP - CHANGE REQUIREMENTS, daily, weekly, monthly

schedule changes

ASSIST - option 11 , 5


Security on the as 4001
Security on the AS/400

  • EDiTOBJect AUThority command

  • WRKOBJ option 2 edit authority

  • See Chapter 9 for more Details

  • Need authority to the Library and to the object



Care maintenance of your as 4001
Care & Maintenance of Your AS/400

  • BACKUP

    • Tape or Savefile

    • All or Changes Only

    • Can be done while people are working


Care maintenance of your as 4002
Care & Maintenance of your AS/400

  • RECOVERY

    • Restore the most recent ALL backups of all libraries

    • Restore all of the CHANGES ONLY backups since the last ALL backup


Why do we ipl on the as 400
Why do we IPL on the AS/400?

  • Reclaim Space

  • Reorganize object pointers

  • Restore lost or damaged data

  • activate device configurations

  • implement PTF’s

System values that influence the type/mode of IPL’s being done

PTF ‘s

Program temporary fixes

in between major operating system upgrades several temporary fixes or small

upgrades can be released and accommodated this way.

CUM ‘s PTF ‘s

cumulative

HIPER PTF ‘s

Hi-Impact and pervasive

Follow the accompanying documentation to install any PTF

Can be made permanent, some must be, but in general not recommended because

they can not be reversed when applied permanently

VERY HARDWARE MODEL DEPENDEND


Operating system upgrades ptfs
Operating System Upgrades & PTFs

  • Operating System Upgrade Every Year

    • Currently at Version 5 Release 2

  • PTFs applied every month

    • Program Temporary Fixes: patches that are temporary until the next release of the operating system
