How to use 10g's SQL tuning support from SQL*Plus

Hi,
I am having problems with my application's SQL queries execution time. I am not tuning guru, I know pretty little about tuning. As I read 10g has a SQL Tuning Advisor. Can I use it from SQL*Plus? I didn't say, but do not have the possibility to access the database, by no other means only SQL*Plus.
TIA
Regards,
Tamas Szecsy

If you have granted the ADVISOR privilege you may use it from SQL*PLUS
Look for examples on the web
(using DBMS_SQLTUNE package)

How to use views in sql script report?

All all
Can any one tell how to use views in sql script report?

Most of the views are based on tables (or other views which are based on tables).
The view typically shows one org at a time based on the context that is set.
If you need records for all orgs, you need to use the underlying tables. Oracle typically names the tables with a _all suffix.
e.g. PO_HEADERS will show records for one org at a time. PO_HEADERS_ALL will show records for all orgs.
Hope this answers your question,

Just purchased a USB Super Drive but unsure how to use it - o instructions provided apart from how to eject a cd. Each time I put in a cd it just ejects it again.Can anyone help.

USB is rarely bootable under Mac OS X and PowerPC Macs. Get a Firewire Superdrive from http://www.macsales.com/ if your intent is to boot the machine. PPC, which is PowerPC, indicates the Mac predates 2006.

I am sorry tell you, this blog is not enough to for me.It's not a blog, it's Chris' website where you download the package from. Once you download the package and unrar it, then the package spec gives instructions (and I think there's instructions on how to install it too).
Kindly let me know if there is any oracle documentation for this .It's not an Oracle created package, it was created by Chris. It's based around the UTL_TCP package if you really want to get into the nitty gritty of how it works, but I don't think you do.

How to use the generated SQL of "Recommendation"

Dear Experts,
I am using KXEN recommendation function. After trained the model, I expose the result in form of HANA SQL. However, I am really have no idea how to make this SQL runnable because there are some subqueries like:
FROM $Dataset "SPACEIN"
LEFT OUTER JOIN (SELECT * FROM WHERE "GRAPH_NAME" = 'Transactions') "PRODUCTS" ON ("PRODUCTS"."KXNODEFIRST" = "SPACEIN".MemberID)
LEFT OUTER JOIN (SELECT * FROM WHERE "GRAPH_NAME" = 'Product') "RULES" ON ("PRODUCTS"."KXNODESECOND" = "RULES"."KXNODESECOND")
LEFT OUTER JOIN (SELECT * FROM WHERE "GRAPH_NAME" = 'Transactions') "NOTIN" ON ("RULES"."KXNODESECOND_2" = "NOTIN"."KXNODESECOND") AND ("NOTIN"."KXNODEFIRST" = "SPACEIN".MemberID)
Please pay attention to the red parts. While $Dataset, I assume it should be the data source which is used to train the model, but how to handle the "GRAPH" parts(the next 3 subqueries)? There are something missing after "FROM" clause, what should I fill in here? why the XKEN will generate sucn incomplete codes?
Thanks for your help!

Hi Richard,
To apply a recommendation model, you first need to save your model in your database. (saving the model in the database for such models and for what you want to do is mandatory).
Once you saved it, you will see many tables starting with "Kx" : KxInfos, KxLinks, KxNodes...
These tables contains information on the nodes available in the data used, on the links between products.
Now, if you generate the SQL code for Hana, the name of your KxLinks table should now be used in the SQL code.
When prompted for $Dataset and $Key, you should specify in place of $Dataset the name of the table on which you want to apply your model. In place of $Key, you should enter the name of the key of this table (e.g. UserId).
In my case $Dataset =>KAR_UniqueCustomers and $Key=>UserID
My generated code looks like this :
FROM KAR_UniqueCustomers "SPACEIN"
LEFT OUTER JOIN (SELECT * FROM KxLinks1 WHERE "GRAPH_NAME" = 'Transactions') "PRODUCTS" ON ("PRODUCTS"."KXNODEFIRST" = "SPACEIN".UserID)
LEFT OUTER JOIN (SELECT * FROM KxLinks1 WHERE "GRAPH_NAME" = 'ItemPurchased') "RULES" ON ("PRODUCTS"."KXNODESECOND" = "RULES"."KXNODESECOND")
Note that your application table must contain:
- A column with the same name as your users identifier in the training dataset. It contains the list of distinct users (stricly 1 row for each customer id)
- A column with the same name as your products name in the training dataset. It can contain the name of the same product for all customers.
I hope you'll make it work !

IaaS SQL/VM - how to use an existing SQL VM

Hello
I have a Cloud Service with a Window Web VM and SQL VM. They both are on the same Vnet. Now I want to add a DB using the existing SQL VM. But this VM does not show up of the Server drop down menu in "Specify Database setting"
wizard. What am I missing here?
If I let the DB Wizard add a new server (leveraging PaaS offer for SQL DB), how can I make sure that this new server shows up on my Vnet (the same one where I have Web VM on)? I assume that these VMs needs to be on the same Vnet to be able to communicate
with each other.
Thanks in advance for your help

Hello,
It seems that you had mix up Windows Azure SQL database with SQL Server on Azure VM. When you create a SQL Server virtual machine in Azure, it similar to on-premises SQL Server installed on VM. You can create and manage databases with SSMS.
If you create a SQL database on Management Portal, the SQL database server host a VM of the datacenter, you cannot using the existing SQL Server VM which your created yourself.
When connect to the SQL database from your azure VM which hosted on Cloud Service, there is no need to create a virtual network, just configure the firewall rule of the SQL database server to allow connection from Windows
Azure Serivces.

Hello,
Have a look at this one:
http://sheikyerbouti.developpez.com/tutoforms10g/tutoforms10g.htm
particularly the chapter about block that contain a collection (2.3.3). The sample is built around a nested table but you have the idea to adapt it to work with a varray.

Problem while executing script in Toad - How to use '&' in the sql script ?

I have to execute sql script in toad. Sql script has one insert query in which one insert-value is 'USA & CAN'. When I executed the script in toad by pressing F5, I got a prompt window asking for the value if 'CAN' as it is after the &.
I tried using[b] {escape '\' } .... but could not resolve the problem.
Is there any solution or workaround to overcome this problem. I have thousands of records with such values and I have to use sql script only.

There is an option in TOAD to change this behaviour.
Look in VIEW/OPTIONS/SQL Editor/
Uncheck the box for "Scan statements for bound variables before execution".
In SQL*PLUS it would be SET SCAN OFF
(desupported version is SET DEFINE OFF)

You don't have permission to access cgi-bin directory ?
How can I do ?

It looks like your web server is not configured to handle
CGI scripts. Does your web server documentation give steps
to configure CGI? Sometimes simple example CGI scripts
are included. Once these are working, then we can help
setting up a SQL*Plus CGI.
If you are using Apache, check the httpd.conf file for the
ExecCGI option. See if you can get the "printenv"
demonstration CGI script working. Then move your SQL*Plus
CGI shell script to the same directory, and try it there.
Don't forget to echo a blank line after the "Content-type:
text/html", else the CGI output will not be interpreted
correctly.
The SQL*Plus 9.2 UG&R has an example of a Perl CGI script
for calling SQL*Plus:
http://otn.oracle.com/docs/products/oracle9i/doc_library/release2/server.920/a90842/ch8.htm#1005951
The iSQL*Plus web-based interface does most of the things
done by a CGI based call to command-line SQL*Plus. Its
"Dynamic Reports" feature is very similar to getting a CGI
script to return a report from a static .SQL file. If you
(i) have Oracle 9.2 (or 9.0 on Windows) installed (ii) don't
mind getting HTML pages back, then it may be a better
alternative to CGI. (Note the SET MARKUP HTML PREFORMAT OFF
command can be used to give traditional character aligned
text, but there will still be HTML page headers and
footers).
