Hi All,

I want to know figure out the IDMS similar function in VSAM, for some functions, we may not be able to map in VSAM environment - what could be the alternate way to tackle?

For Example:
IDMS command - VSAM Command
READY - Open
FINISH - CLOSE

Like the above commands, i want to know the details for the below:

Record Currency -?
Set Currency -?
Area Currency -?
Run Unit Currency -?
Currency loss -?
Storing DB-Key -?
Retrieval By DB-Key -?
FIND Current -?
OB CURRENT -?
IF EMPTY -?
IF MEMBER -?

Also for Oder options like first, last, next, prior, sorted.

Hello,

IDMS is not really comparable with VSAM. . .

VSAM is simply an access method (random or sequential). IDMS is a database management system.

Hi,

Yes, You are correct.

We are going to decommision the IDMS and ADSO. So we are planning to implement in VSAM and CICS in similar functionality. Though it may not be the exact copy, we are trying out to get the several alternatives.

Hello,

If the decision is not final, suggest someone consider going to another database system rather than only VSAM. I do not believe VSAM will have all that is needed to satisfactorily replace the IDMS environment.
