I'm working on getting Oracle 9i working on an AS4100 running TRU64 5.1A
(Rev. 1885). 2 processors - 1Gb main memory.
I've encountered the following problem a couple of times. I edit some static
DB initialisation parameters and then restart the DB. Then the server hangs
with the console (VT420 terminal) message:
"Unable to allocate requested swap space"
This leaves me unable to start up a session as the console (terminal) has
this message continually scrolling, so I cannot get a prompt. To enable
logon I have to halt the system and then re-boot.
I can investigate the Oracle issues that cause this (requesting too many
resources), but my question is this;
How do I configure the swap so that it behaves more rationally. By this I
mean, I would like to see the process requesting swap (ie: the Oracle
process) to get killed after the O/S has highlighted the swap issue. Or some
other solution that will avoid me running out of swap each time I look into
the Oracle issue.
Here is my swap configuration.
Any help or recommendations are gratefully received,
Mat.
