Setup the profile of the user using
ulimit -s to a higher value.
Possibly one suggested in your database vendor documentation.
If ulimit fails to set to
<value>, you will have to adjust the maxssize kernel parameter, then use ulimit.
Be sure to read the manual pages of ulimit and maxssize parameter (this is what i like about hpux, man <kernel parameter> is golden
)
Please for future note specify your shell (shell of the user the database processes runs under) and exact hpux version.
Folks here can be more exact in helping you with that information upfront.
I have not used the variable mentioned here so i cannot comment on that, give it a shot with standard tools mentioned above.
Hope that helps
