Thread: sort mem size

sort mem size

Does any one have a good idea of what the sort memory is best set at.  I have read Bruce suggestions but they are vague and just say make it bigger till you don’t have page ins.  I wonder if there is someone who knows what a good setting is for a Db with tables that are over 700 MB and total DB size of 6GB + ?  The Machine has 2Gb ram with a shrmax setting of  1800000000 about 1.6 gb

Thanks in advance for your help

If there was a simple answer, I would have given one in the article.
Does anyone know a good value?
