I was trying to transport a large number of tablespace datafiles from one database to another, and impdp kept crashing with “PL/SQL: numeric or value error: character string buffer too small.”
It turns out there is a limit on what you can put on a single line in a parameter file. Hence if you have something like:
then you might run into trouble. It’s easily fixed however – just put the entries one per line
transport_datafiles=/long/path/file1 transport_datafiles=/long/path/file2 transport_datafiles=/long/path/file3 ....
You know what scares me?
In this day and age of “big data”, PCs with multi-GB memory, multiTB main memory servers, we are still seeing overflow errors in Oracle input character fields.
Someone needs to bring the entire Oracle development group into this millennium…
