Hello,
Today the database shutdown and I received error codes 01034 and
27101. When I tried to restart and connect I got 00821. The 00821
was due to the specified value of sga_target was too small. To get
the database started, I created a pfile from the spfile, edited the
pfile's sga_target line (specified more space; went from 320M to
640M), created a spfile from the pfile and started the database back
up.
I was able to start the database but now I want to put the sga_target
back to the value where it has been for years. When I did this from a
command line it failed:
alter system set sga_target=320M scope=both;
ORA-02097: parameter cannot be modified because the specified value is
invalid
ORA-00827 could not shrink sga_target to specified value
I'm stumped here... how can I set sga_target to a smaller value than
the current setting? Suggestions are greatly appreciated.
Thanks!
