Location of actual data in datasets

In Dataset Management while copying a dataset without giving any explicit path which location the dataset gets created. Also .ds is the descriptor file. Where is the actual location of the records in the dataset. Is it a single path or multiple path in the disk.

Gurus,


I was doing a quick search in the Forum regarding more information about datasets including the above question,

Can you please explain (or point to forum locations if this was previously discussed? )

When I go through the documentation " It just says that dataset stores data in a persistant form)
From the documentation , a dataset is an OS file managed by a control file.

What does this exactly mean,
Do we create datasets from sequential files and use these files instead of sequential files?

what are we achiving by using datasets? Where can we look at the actual data ?

Thank you

Dataset Path is mentioned in resource disk in Configuration file

Multiple, determined by the number of resource disk references in the current configuration file. The actual files have system-generated names, which are recorded in the descriptor file. This is not a text file; use the Data Set Management tool to learn the location of the segment files (select any node and these are in the bottom grid).

Don't hijack someone else's thread unless you have exactly the same question. Here you don't. Please start a new thread. It will make life easier for future searchers.

I could not view the response. I am assuming that the resource disk path written inside the config file for each node stores the dataset data.

Meanwhile, spend some time investigating what the Data Set Management tool can show you about segment files.

I did check in the dataset management and the segment file paths. The data is stored in segments in each of this path for each node. Thank you all.
