OK, after I changed the memory settings for SGA_TARGET and PGA_AGGREGATE_TARGET, I ran shutdown and then issued startup and I got this:
ORACLE instance started.
Total System Global Area 431038464 bytes
Fixed Size 1333676 bytes Variable Size 297797204 bytes Database Buffers 125829120 bytes Redo Buffers 6078464 bytesDatabase mounted.
