这个是在aix上的一个bug:具体见metalink:758568.1

原因:

In emctl.pl we have a command as below: 

ps -p $PID -o cmd --cols 1000 |grep DEMDROOT 

In AIX platforms for some OS kernels, this command doesn't work. The correct command is: 

ps -p $PID -o args | grep DEMDROOT

解决办法:

If you get these errors while starting DBConsole, follow below action plan: 

Follow below action plan. 

a) Stop DBConsole - 

'emctl stop dbconsole' 

b) Take backup of 

'emctl.pl' from $ORACLE_HOME/bin 

c) Edit emctl.pl and goto line number 1249, which is: 

my $ps=`ps -p $PID -o cmd --cols 1000 |grep DEMDROOT`; 

Modify above line as below: 

my $ps=`ps -p $PID -o args | grep DEMDROOT`; 

d) Save the file. 

e) Start DBConsole - 

'emctl start dbconsole' from $ORACLE_HOME/bin

结论:

修改 $ORACLE_HOME/bin/emctl.pl文件中内容后,问题解决.
