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

WHY ?

BACKUP

6

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 7

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 backup Step 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 Configuration Libraries when it changes new release PTF’s -when it changes devices added network changed when updates received IBM licensed products Security data new users / reassignments user profiles authorizations OBJECTS - SAVCHGOBJ DAILY when changed 10

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.

11

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 12

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 13

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 14

It is best to run backup with *SAVSYS authority For saving *SAVF files to tape you use the

SAV

SAVF

DTA

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 16

RCLSTG

Reclaim storage

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 17

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 18

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

19

Corresponding Save/Restore Commands Save Command Used SAVSYS Restore command to Use RSTOBJ RSTUSRPRF, RSTAUT RSTCFG SAVSECDTA SAVLIB SAVOBJ SAVCHGOBJ RSTUSRPRF, RSTAUT RSTLIB RSTOBJ RSTOBJ 20

Care & Maintenance of your AS/400

• Reboot! - IPL 23

Care & Maintenance of Your AS/400

• BACKUP – Tape or Savefile – All or Changes Only – Can be done while people are working 24

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 25

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 QIPLSTS , QIPLTYPE 26

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