Re: oninit: Fatal error in shared memory creation

Regardless of the original reason for failing to come up (which may already be fixed) you need to delete remaining shared memory segments. You can calculate the unique key for your server by calculating (in hex) (SERVERNUM * 10000)+52564801; in your case you obviously left SERVERNUM as 0 when initializing OnLine. I assume that you have no other instances of OnLine running; remember that each instance must have a unique server number. (SERVERNUM is found in your Online configuration file.) You can then use the resultant number to (as root) use the ipcrm command and remove the offending segment(s). Note that you may want to use ipcs -m and look for other segments with the owner root (or informix) and informix as the group. These are likely other segments taht will have to be freed before OnLine will live up to its name. HTH, David "Kevin M.

David, Thanks for your time and your help. I removed the offending segment, but now I'm seeing another error: shmat: [EIVAL][22]: shared memory base address illegal using 0xa100000, needs 0xef400000 mt_shm_init: can't create resident segment Thanks again for your help. I am usually pretty good about searching through documentation to debug stuff like this, but I couldn't find anything. Not even on SHMSEG or SHMMAX. If you can point me to something that would help, please do. Thanks for your help.

SHMSEG and SHMMAX are Solaris kernel configuration parameters you need to increase the values of these in the kernel build config files, or add them there if they are absent and assumed to default, and then build and reboot a new kernel. Your system administrator will know how to do this. You can make SHMMAX 2GB so that ANY size segment can be created and then you only have to worry about SHMSEG if other applications on the machine will be using shared memory extensively. You may also need to adjust the kernel parameter that determine the amount or percent of shared memory that may be marked RESIDENT so you can turn on the RESIDENT parameter in the ONCONFIG file.
