Re: Total users

Actualy, in our experience the 128 is meaningless. As soon as you reach 99 users your system will no longer allow any further attachments, it WON'T allocate more shared memory for more users, and it WON'T give you any meaningful message about what is going on. The number of users has not been eliminated, just moved. When you set up NETTYPE [found in onmonitor under Parameters/Performance] you can change to 150 users as follows: NETTYPE ipcshm 1 150 CPU Your input to these fields will vary depending on the number of CPUs etc, so look it up in the manual but include the 150 in the users column to get the number of users you need. You will have to bounce your server, and you will need more memory for start up. ssouthwe @ pcshs.com (Schuyler Southwell) 08/29/96 11:30 AM To: informix-list @ rmy.emory.edu @ INTERNET cc: (bcc: Kate Tomchik/IS/SSC/THD) Subject: Total users (Informix OnLine DS 7.12.UC5, 150 user license on Sparc1000 Solaris 2.4) This question is prompted by a certain nervousness caused by the following: Last line of onstst -u (on a slow day) 85 active, 128 total, 99 maximum concurrent (and, yes, most of these are 'REAL' user threads, not DS threads or some other misleading count) The Manual says (Administrator's Guide Volume 2, onstat -u description) "The number of active users and the maximum number of users allowed are also indicated. The maximum number of concurrent user threads is specified as USERTHREADS in the ONCONFIG file." Our release notes state 11. The following configuration parameters have been eliminated: USERTHREADS, TRANSACTIONS, TBLSPACES, DBSPACES and CHUNKS. INFORMIX-OnLine Dynamic Server Version 7.10.UD1 allocates resources dynamically for the structures that these parameters controlled in previous releases. Why is the "maximum number of users allowed" 128, and not 150? The "maximum concurrent" is the dynamic replacement for the USERTHREADS parameter, yes? This will increase as demands increase? What happens when 85 or 99 reach the 128 total? +--------------------------------------------+--------------------+ | Schuyler L.
