Hi,

1) Running a dataset on 4 node config file, and after the run if i change the number of nodes to 6, Can i read the data in the dataset?
2) Running a dataset on 4 node config file, and after the run if i change the node names Can i read the data in the dataset?
3) If i cant read that, how can i recover the data from the dataset?

Thanks in advance

Kind Regards,
Aditya

The dataset stores information pertaining to a configuration file and if that is changed the dataset will be corrupted so my guess to that would be a NO to all three.

Can't we recover the data.

Yes, by creating a job that reads it or using a command that dumps it, with the APT_CONFIG_FILE environment variable set to the same configuration file as the one that was used to create the Data Set. Or a compatible one.

Hi Ray,

Thanks for the reply

What if the node names are changed, even then can i recover the data?

Probably, provided that they are identically defined to the node names under which the Data Set was written. And I do mean IDENTICALLY.
