I have very little experience as oracle DBA or developer.I still post lot of simple questions here in the forum.
1.ILT.very good but i used sql plsql.backup from sybex
3.sample questions like for example i found 20 questions in our
forums it self by searching "1z0-026" and some google.
4.the major thing i did was going is concentrating those chapters
where we get more questions like for example in PT we got more
on chapters like sharedpool and buffer pool.I try to read and
practise questions as many times as possible, doesn't mean i
leave the rest.
5.the order i took was(sql,aa,br,net,PT).one way network was easy
and difficult because concept is difficult but questions are
straight forward from book, no other logic
6.DBASUPPORT members,moderators were really helpful in answering
lot of sample questions I got from google etc.I am very thankful
to each and every one.
