Classic question is: when someone called you, said : "database is slow",
what would you do?

现在DBA看report是run自己的script还是去EM上看？感觉oracle也向傻瓜型发展。

>> 现在DBA看report是run自己的script还是去EM上看？
I think it really depends on different situations. Being able to run scripts
only from command-line is a must-have skill, and it works for all situation
and across verisons and different shops.
Not every shop has GUI tool. we don't have EM at this moment
>> 感觉oracle也向傻瓜型发展。
In terms of managability of RDBMS software or their marketing goal at least,
it seems to be true.
But I don't think an Oracle DBA can be challenged to any less extent by less
number of issues. Some area of automation eliminates the intervention of a
DBA, but do we worry less? New features also bring new issues or point-of-
failure to worry.
RAC brings higher availability, but it requires DBA to be smarter or broader
in understanding of storage, network in addition to just database server.

then your question to them would be "what is slow" Developer said it was
slow. What exactly is the "IT" , this question could only be answered by the
java developers.
yes Oracle/sql/mysql DBA can analyze the "waiting events" but there is no
way for DBA to know how important a "waiting events" are related to the
application...
the best source of this information is in frontend code.
I ask this question to the developers all the times. it worked every time!
