memory allocation for 3rd party applications

mike worrell — Tue, 10 Jul 2001 12:16:19 GMT

Is there a way to allocate memory usage
for certain applications. We have a 3rd party
product that gives "no core memory" message
from application. Memory on the system is
excellent,Sometimes message comes up and other times all works ok. The 3rd party apps vendor is telling me I may need to change a parm to allocate more memory to certain applications.
Anybody have any idea what I could change??
Thanx
Mike

Hi Mike:

Its quite possible that your application needs a larger data stack (maxdsiz). Take a look at the Kernel configuration parameter document below, particularly the section on Process Management:

Hi Mike,

You may also need to increase maxtsiz (the limits the size of the actual code as opposed to data). In rare cases it is necessary to increase maxssiz (the stack segment size). You can make these large as they consume no resources. The only downside is that if you have a true memory hog or leak, the system does not kill the process as soon.

thanx James and Clay.
Will try increasing the values you mentioned
and see what happens.
