What to check

The server process is running with parameters:

./server -w 300 -p 7819-12818 -m 7809 -k -l /software/ogg/191/ggserr.log

oracle@qa-2-dbs-01>% ls -l /software/ogg/191/ggserr.log

-rw-r----- 1 oracle dba 3337659 May 19 20:01 /software/ogg/191/ggserr.log

File /software/ogg/191/ggserr.log must be owned by oracle, else the server process would not start.
