Informix - Problembeschreibung

Problem IT27471 Status: Geschlossen

FAILED CONNECTIONS COULD LEAD TO INCORRECT VALUE FOR SHMEM->SH_RSNACTIVE
WHICH COULD CAUSE PHYSICAL LOG OVERFLOW ASSERTIONS

Produkt:
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10
Problembeschreibung:
Under specific failed connections, it's possible that
shmem->sh_rsnactive will be decremented prior to it having been
incremented.  If this happens often enough
shmem->sh_rsnactive can go to a negative value.  This can lead
to physical log overflow because this value is used in the code
to determine if a non-blocking checkpoint needs to be switched
to a blocking checkpoint, to prevent the physical log from
filling.

The most likely cause of failed connections would be servers
that have SHMTOTAL set to a non-zero value, and the server has
allocated SHMTOTAL amount of memory.
