• 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 ?????????.

4

Security on the AS/400

• EDiT OBJect 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

DSPSYSVALwith QMODELQSRLNBR

ETC.

WHY ?

BACKUP

7

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

8

Disaster Planning• A disaster plan should be well thought out and

well documented.

• A typical BACKUP plan might be to do full 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.

Disaster Planning cont’d

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

10

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 releasePTF’s

Configuration - -when it changesdevices addednetwork changed

Libraries - when updates receivedIBM licensed products

Security data - new users / reassignmentsuser profilesauthorizations

OBJECTS - SAVCHGOBJ DAILY when changed

requirements

A dependable backup plan MUST ensure that EVERY object and category of object has been and is saved on a regular basis.

12

BACKUP MEDIA

TAPE - DISKETTE - SAVF

Before use initializeINZTAP - INZDKT

To see the contentsDSPTAP - DSPDKT - DSPSAVF

or use the menu’sGO TAPE - GO DISKETTE - GO SAVE

13

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

14

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

16

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 theCRTSAVF 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

17

Reclaim storageRCLSTG recovers all space in use by “FREE” objects

objects with no library reference or not owned by ANY user! TIME !

Clean upRemove objects that are no longer required

Clear libraries - CLRLIB

large dormant files - CLRPF

leaves structures untouched

18

Preparatory Steps for a backup

Initialize the mediado cleanup tasks reclaim storage

GO ASSIST or GO SETUPBACKUP tasks

set up automatic scheduling ! *SAVSYS, Restrict access, notify everybody ‘SNDBRKMSG’

ENDSBS except QCTL

run the backup

19

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

Care & Maintenance of your AS/400

• Reboot! - IPL

24

Care & Maintenance of Your AS/400

• BACKUP– Tape or Savefile– All or Changes Only– Can be done while people are working

25

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

26

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 ‘sProgram temporary fixes

in between major operating system upgrades several temporary fixes or small upgrades can be released and accommodated this way.

CUM ‘s PTF ‘scumulative

HIPER PTF ‘sHi-Impact and pervasive

Follow the accompanying documentation to install any PTFCan be made permanent, some must be, but in general not recommended because

they can not be reversed when applied permanently

VERY HARDWARE MODEL DEPENDEND

28

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
