OpenEdge Getting Started: Installation and Configuration - Product ...

Chapter 6: Administration Utilities
If shared memory or semaphores are allocated incorrectly, OpenEdge displays an error
message when it attempts to start an additional user or server. For example, if SEMMNS
is set too low, PROSERVE fails and displays the following message:
Server: Semaphore limit exceeded
Server: **The server terminated with exit code (X) (800)
Change the relevant parameter values and reconfigure the kernel in response to
semaphore or shared-memory errors at startup. Table 35 lists the parameters that you
might have to raise in response to various OpenEdge error codes.
Table 35: Error codes and kernel reconfiguration parameters
Error code Parameter to increase
1081 SEMMNU
1093 SEMMSL or SEMMNS
1130 SEMMSL
1131 SEMMNI and SEMMNS
1135 SHMMAX, MAXUMEM, and MAXUP
On the AIX platform, when starting a database with
large shared memory requirements (for instance,
when the -B exceeds the allotted system paging
space), the system may become unstable if the
PSALLOC= early environment variable is not set.
1137 SHMMNI
1175 SHMSEG, MAXUMEM, and MAXUP
1195 SEMMNS
Note: The Blocks in Database Buffers (-B), Lock-table Entries (-L), and Number of
Users (-n) startup parameters all affect shared-memory usage. The Number
of Users (-n) and Maximum Servers (-Mn) parameters affect semaphore usage
(each user or server process uses one semaphore). Before reconfiguring your
kernel to increase shared memory or semaphore allocation, see whether you
can lower these startup values.
