Hello,
I am learning Natural and Adabas through manuals… There is something i do not understand from the manuals,and i am trying to find the answer in Vain. Its regd how a data is stored in Adabas.
I took the below table from Adabas documentation. If you notice the ISN 10, ISN 11 and ISN 12, it resides on same block number, but it contains different data. I was under the impression that ISN would be unique for the data record until it is reassigned or when data gets deleted. Would you be able to examine the below table – blk size 237, and let me know how same ISN would be used by ADABAS for storing different datarecord. And possibly what would address convertor contain in such case?
