Question

I have Solaris machine with oracle Release 10.2.0.4.0

I have problem – I cant startup oracle

when I try to start oracle by the command:

       hagrp -online oracle1 -sys machine1a

I get:

      oracle1   machine1a      Y      N       PARTIAL|FAULTED

remark ( hagrp -clear oracle1 -sys machine1a not help )

After checking and debug the problem I find that oracle not start up

because wrong param – shared_pool_size (this param was set to 0 , while need to set this param to 2G)

So I want to set the param shared_pool_size to 2G but I can’t because oracle is down !!!

My question – how to set the parameter shared_pool_size to 2G in spite oracle is down ??? , is it possible ???

If you were starting from an old-style init.ora parameter file you could just change it in that. The scope in your alter system suggests you’re using an spfile. You can startup nomount to make parameter changes, then shutdown again and try to start normally.

Are you sure you’re connecting to the right database though? The output from your sqlplus command doesn’t say connected to an idle instance, so it looks like whatever you’re connected to is already running. Check where you are before running anything, and note any parameters you change first (e.g. with output from show parameters).

Based on conversation in chat…

You can create a temporary pfile, edit that and test starting up with it, and then when happy with the new configuration recreate your spfile, and finally restart from that. The steps are:

create pfile='/tmp/init.ora' from spfile;
-- edit /tmp/init.ora and change parms as needed 
startup pfile='/tmp/init.ora';
-- repeat as needed until successful start
create spfile=’/path/to/spfile.ora’ from pfile=’/tmp/init.ora’;
shutdown
startup 'spfile=/path/to/spfile.ora';
