Re: multiple concurrent imports into the same database

I routinely use this method if I need to import a large file with multiple = tables. I have done it with file less than 2G simply using ignore=3Dn. I = get a lot of import errors because an object already exists, but the job = completes successfully in about 4 hours. I have also done it with = compressed files which would decompress to more than 2G. In that case, I = use a unique pipe for each import which decompreses the single dump file. = I have run up to 6 imports simultaneously with success. The caveat is = that nothing else can really be happening on the server in question, = because all those processes use up a lot of resources.

Just to be curious,

Is it possible to run say, two, three, four, five simultaneous imports against the same database?

Would that speed things up?

Thanks.
