My client did an unload of an ADABAS system containing approximately 1,500,000,000 records. This took approximately 7 hours. using ADARUN with the ADAULD command. It then took an additional 20 hours to decompress this data using ADARUN with ADACMP DECOMPRESS
They are looking for ways to perform these tasks in less time - Could ADABAS sustain multiple concurrent unloads and decompresses?
I’ve also asked them to try using the INFILE command with DECOMPRESS rather than doing separate UNLOADs and DECOMPRESSes
