The table being created is approximately 2.2B records.
LongReadLen => 2000000100 # add 100 to the longest possible long,
+ as per DBI man page
Why are you setting LongReadLen so big? It has nothing to do with the number of records
you want to retrieve but the size of possible blob data in a record. It could be the underlying
OCI lib is running out of space based on the LongReadLen ... if you have no blob data in the records,
just remove LongReadLen. If you do have blob data, and you have 2G of blob data for each of the
2.2B records, well .. yikes.
