Try onmode -F (Informix Online Dynamic Server Volume 2 Version 7.1, Page 40-49) The original poster had a problem as follows:- Message Log File: /d2/informix/online.log 13:20:49 size of resident + virtual segments 162562048 + 362864640 >512000000 total allowed by configuration parameter SHMTOTAL 13:20:49 out of virtual shared memory This means that the Informix DBa needs to increase the Informix paramater SHMTOTAL. Note if this value is increase UNIX kernel paramaters associated with the maximum size of a process may need to be increased E.g. HDATLIM,SDATLIM,SVMMLIM,HVMMLIM,MAXMEM,MAXUMEM (Not all of these apply on all platforms. Description are maxmimum size of a process, maximum amount of virtual memory that may be mapped to a process or similar. Also parmaters related to maximum size of a shared memory segment may need to be increased. -- David Williams
