There is no set formula, except that it is the total of all structures whose sizes you have declared in the uvconfig file. You can determine the existing size of the disk shared memory segment, and it is reported when you use the uvregen command to reconfigure it. Similarly, the size of a user's printer shared memory segment can be determined (analyze.shm -p), and the current size of the BASIC Catalog shared memory segment and NLS character map shared memory segment are reported when these are loaded.
UniVerse's demand for shared memory does not increase because you have increased your amount of real memory (RAM). Use the kernel parameter sizes recommended in the installation notes for UniVerse and, provided nothing else is consuming too much shared memory (and even that can be started after UniVerse) you will have no problem. If UniVerse was working OK with the smaller amount of memory, then it will continue to work OK. That you have more memory available will be able to be used by non-shared memory consumers, such as query optimization, sorting, scratch space, and so on. You might like to look at the uvconfig parameters relating to these areas. Do you plan to increase the number of simultaneous users? If so, beware of increasing per-user structures' sizes too much. ----- Original Message ----- From: Ang Suan Yong <[EMAIL PROTECTED]> Date: Tue, 8 Jun 2004 16:13:38 +0800 To: U2-Users New Lists <[EMAIL PROTECTED]> Subject: [U2] calculate Universe Share Memory > Dear All, > > We are upgrading our unix sun server (sun-fire 6800) memory to 24GB > memory .
