Release 10.1A: OpenEdge Deployment:
Startup Command and Parameter Reference

Shared-memory Overflow Size (-Mxs)

Use Shared-memory Overflow (-Mxs) to replace the default value of the shared-memory overflow area; it does not increase it.

Operating system and syntax	UNIX Windows	-Mxs n
Use with	Maximum value	Minimum value	Single-user default	Multi-user default
Database Server	Varies1	1	–	Varies

1The maximum is limited only by the size of the signed integer data type on the system. If your system uses a 4 byte integer, then the formula is: 16KB + (n*300). For all other systems, the formula is: 16KB + (n*400).

n

The size of the shared-memory overflow area in kilobytes.

The overflow area is appended to the shared-memory area. This parameter is relevant only on shared-memory systems.

If the overflow area is too small, OpenEdge exits with the following message:

SYSTEM ERROR: Out of free shared memory. Use -Mxs to increase.

Depending on the operating system, OpenEdge rounds the shared-memory area size to the next 512-byte or 4K boundary.
