./ means current working directory. On Linux, that's what /proc/<pid>/cwd
points to. Solaris should have a similar pseudo file. In addition,
Solaris has pwdx command (`pwdx your_pid'). Oracle on UNIX/Linux always
sets the cwd of its processes to $ORACLE_HOME/dbs (On Windows, it's
%oracle_home%\database).
I tested in 11.2.0.1 on Linux. It doesn't seem to check ./alert_$SID.log
first. After I did
touch $ORACLE_HOME/dbs/alert_$ORACLE_SID.log
exec dbms_system.ksdwrt(3, 'test') still writes to the existing
alert.log, leaving the newly touch-ed file at size 0. Maybe Oracle
corrected the problem in this version?
