DescriptionMaximum valueDefault valueLMX parameter
Specifies the
maximum number of
contexts
system-wide. Each
Oracle process
typically has two
LMX contexts.
"Contexts" and
"minors" are used
interchangeably in
the documentation;
"context" is an
Oracle-specific term
to specify the value
in the lmx.conf file.

of communication
endpoints for
transferring
messages from the
sender to receiver in
a uni-directional
manner.
655354096lmx_port_max
Specifies the number
of addressable
regions in memory to
copy LMX data.
655354096lmx_buffer_max
If you see the message "no minors available" on one node, add a configuration
parameter that increases the value for the maximum number of contexts.
Note: The error message may contain the term "minors," but you must use the
term "contexts" when changing the parameter value.
Warning: Increasing the number of contexts on a specific system has some impact
on the resources of that system.
