My server keep on adding memory segments ( atleast two segments / day ) while the number of users or sessions does not increase. JC> There are processes out there (sorts, index creates ??) that are allocating this memory. Onstat -g mem shows that the global pool is the biggest usage. What is this global pool. Also I tried onmode -F to free some segment but it is not working. JC> onstat -g seg show that these memory blocks are being used. onmode -F will not free them if they are in use. The statistics are as follows. . . .. stats clipped . . . . What are your settings for SHMVIRTSIZE? I'd recommend that you increase SHMVIRTSIZE by (19 * SHMADD) so as to allow this virtual memory to be a single memory segment. If you're running HP, you would probably even get a performance increase, as HP doesn't really like more than three active memory segments.
