In this first my blog entry I wish to post the code for send an Email message from one sender to one receiver.
The code is the follow:
v_From VARCHAR2(80) := 'sender.mail.com';
v_Recipient VARCHAR2(80) := 'receiver.mail.com';
v_Subject VARCHAR2(80) := 'test subject';
v_Mail_Host VARCHAR2(30) := 'smtp.libero.it';
crlf VARCHAR2(2) := chr(13)||chr(10);
v_Mail_Conn := utl_smtp.Open_Connection(v_Mail_Host, 25);

AIX is like an Unix environment awesome original, same to HP-Unix, and, if you have a plan to install Oracle RAC, you need to pay attention. I note some tips in this article to help.
1. Checking Operating System Packages
# lslpp -l bos.adt.base bos.adt.lib bos.adt.libm bos.perf.libperfstat \
bos.perf.perfstat bos.perf.proctools rsct.basic.rte rsct.compat.clients.rte \
If not, install on AIX source by smity. It's easy, but remember, some packaged requires your IBM's account to download.

I worked on Unix many years ago, however, Solaris, AIX and HP-Unix are the platforms I often did with. I'm DBA, but there are not any System Administrator in my company, and I .. do the System's business at all.
Before ZFS becomes popular, UFS was always the best choice for Solaris, especially in M's series, example: Sun M-3000, M-4000, M-5000 ...etc. The M series does not support Hardware Raid, but only software, and this article do the brief of creating the software raid in. It's one of task list before configuration and installation Oracle in Solaris 10.

Indexes may improve the performance of SELECT statements, but what about DML? This simple demo shows how bad they can be.

The CONNECT BY syntax provides a useful pseudocolumn, CONNECT_BY_ISLEAF, which identifies leaf nodes in the data: it’s 1 when a row has no further children, 0 otherwise. In this post, I’ll look at emulating this pseudocolumn using recursive WITH.
