Why do I want to talk about the Why do I want to talk about the not talked about products?not talked about products?

• Because Gary is paying me.• Because they are good.• Because I like the sound of my own voice.

• Because I believe not everybody knows about them all.

• Because I believe it will prolong the life of MODEL 204 if people make more use of them.


My AimMy Aim

• Not to describe how they work.

• Not to describe them technically.

• Let you know why you need them.

• To invite you to share your ideas on how to get the most from them.

FastFast UnloadUnload


FAST UNLOADFAST UNLOAD

• Built to speed the work of unloading data out of MODEL 204.

• 5 to 10 times faster than standard MODEL 204.


FAST UNLOAD - UsesFAST UNLOAD - Uses

• To extract data out of MODEL 204 for external systems.

• Because some processing was faster to perform outside of MODEL 204.

• File reorganisation.

• Allows more use of the invisible Index


FAST UNLOAD – rethinkFAST UNLOAD – rethink

• To extract data out of MODEL 204 for external systems.

– If the aim is to put the data into an external system such as a spreadsheet that can be done directly using the JANUS products today.

– If the external systems start by summing the data, that can now be done on the way out by FAST UNLOAD itself.



• Because some processing was faster to perform outside of MODEL 204.

– FAST UNLOAD will now allow you to SUM and do mathematical work on data and pass that data straight back to USER LANGUAGE code.



• File reorganisation.

– Restructuring (shuffle records, fields)– Tuning

• Change field attributes• Managing Extension records

• As part of a reorganisation.

• Allows more use of the invisible Index


FAST RELOAD – Re thinkFAST RELOAD – Re think

• Check correct numbers of buffers specified


FastFast BackupBackup


Fast BackupFast Backup

• ‘Plug-in’ replacement for M204 DUMP / RESTORE


M204 dump / restoreM204 dump / restore

Uses standard database I/O routines uses standard buffer management routines

Results in :

Inefficient I/O usage

Significant disruption to users

‘Hung’ online


Fast Backup - Problems Solved!Fast Backup - Problems Solved!

• Uses OWN buffer pool.

• Full track I/O.

• Does not interfere with online.

• 5 to 10 times faster than Dump/Restore.

• Built to speed the work of cross region access

• 100’s of times faster than standard MODEL 204 CRAM.

• CCA released their own version with MODEL 204 v 4.1


FAST CRAM - UsesFAST CRAM - Uses

• Speeds CICS to MODEL 204

• Speeds BATCH2 work

• Speeds any other reason when CRAM is required

RULES for TUNINGRULES for TUNING

1.There are no rules

2. All you try may not work


FIND TUNINGFIND TUNING1) Remove fixed criteria's outside of FOR

Loops.

2) Beware FIND's with GT , or LT very expensive.

3) Beware FIND's with LIKE

4) Beware FIND's with Wild Card searches

5) Consider option of removing some criteria from find, then checking in a FOR loop.

6) Merge multiple keys into 1.

7) Reorganise files.

8) Change file structure.

9) Sort Every File.

10) The majority of indexes should be ordered.

If you have SIRTUNE.

It is simple to use.

If you use it you will save a large slice of the CPU M204 uses.
