IS ADABAS C same as normal ADABAS?
What is difference?
Definition:
ADABAS C is SAGA’s Adaptable Database management system.
thanks
Adabas C (centralized?) is the one most of us use - “normal Adabas”, as you say. It’s available on the mainframe and Linux/Unix/Windows.
Adabas D (distributed) is a relational version.
There was an Adabas M version for a while, too.
thanks, what about the terminologies.
we are running ADABAS on z/OS.
I am reading ADABAS C Fundamental Guide, they had mentioned General Control Block (GCB), File Control Blocks (FCBs) and Free Space Table (FST). But I did not find this in our ADAREP.
These components are used internally by Adabas. We have no direct access to them, so there is no use in including them in an Adarep.
These control blocks are discussed in the Adabas Internals training class. SAG’s Technical Forums are not a replacement for such courses.
But a lot of information ADAREP shows you is obtained from GCB and FCBs. FST = “Unused Storage”.
I did not find “Unused Storage”. in ADAREP

What should be GCB and FCBs. FST?
The “unused storage” printed on an ADAREP only tells you about the free space
at the container level, but not at the file level, i.e. you will not see FST information there.
The report gives you “unused” informatio at the file level
File Name Alloc.: NI UI AC Data/Cyl
Unused:
1 CHECKPOINT 3 3 12 100/3
1 3 2 52/1
4 ADASCR 2 2 2 30/1
4 1 0 29/0
8 FNAT 17 13 66 1800/60
8 15 10 1797/59 but this has nothing to do with the FST either.
When you look at the physical layout

simply because the low range contains the GCB and the FCBs, how many
blocks are reserved for that depends on the maxfiles setting.
Is there a way to Migrate Adabas C (Mainframe) into Adabas D(Unix)?
If yes and SAG tools are available on this, please provide me the needed information.
Thanx.
Yes, a number of tools are available, but all at additional cost.
With “built in” tools you will have to unload/decompress from Adabas C,
creating fixed format output, then on Linux somehow “flatten” the structures
and load into Adabas D.
there is no any info about differences adabas c and adabas d on the website.

how can i reach to documentation for “adabas c in linux”?
Adabas C == alias Adabas Open Systems == alias Adabas LUW
