mt_shm_init: can’t create `resident/virtual` segment.

Cause

The causes for the failure to create the resident or virtual segment are as follows: (1) the segment size is less than the minimum segment size; (2) the segment size is larger than the maximum segment size; (3) allocating another segment would exceed the allowable total shared-memory size; or (4) a failure occurred while the database server was trying to allocate the segment.

Action

If you suspect that this error was generated because of item 1 or 2 in the preceding paragraph, Contact Technical Support. To correct item 3, increase the SHMTOTAL value in your ONCONFIG configuration file. For additional information about errors generated because of item 4, see your logical-log file.
