What is the recommeded maximum number of open file descriptors for day to day operation.
The installation documents for the WebLogic server software recommends says that for installation " ....the maximum number of open file descriptors must be no less than 4096...."
But, for day to day operation what is the recommended value. We are currently running a 10g Appserver and our current max value is set to 256. When we asked the sysadmin to bump the number to 4096, he went nuts. He says unless we can show him where it indicates that the 4096 is required for day to day operation, he will drop the value back to 256.
I can't seem to find where there is a "published" recommended operational value.
