Hello!
Can anyone walk me thru the steps to change the length of an IMS DB?
As far as I understand:
a)Change the DBD with the new length
b)Recompile all PSBs accessing that DB
c)Create ACBs (?)
d)Change the IO-area used by the cobol programs to access the DB
e)Recompile all the cobol programs using that DB (to pick up the changed IO area)
I am not sure if I have to perform the steps b and c.
Would be nice if anyone could throw some light on this. |

Hi naive,
we need to recompile the PSB's too i feel. this is mandate, if there happens to be change in key of segments.
Can you please throw some light on ACB?
thanks in advance,

Ummm I am not sure about the ACBs either. I know that they are made from a combination of the PSB and the DBD, and that usually they are required to run online IMS programs.
Other than that I am not at all sure about them. |

| And oh .. there is no change in the Key, only an increase in length of the DB due to increase in length of some nonkey fields. |
