Is it possible to make PCTFREE 0 a database-wide default via init.ora ?

In our batch environment we drop/create lots of tables as follows - CREATE TABLE X NOLOGGING PCTFREE 0 PARALLEL AS SELECT .........
Since the tables get created from scratch every time and don't get updated - we use PCTFREE 0 to minimize space usage and speed up overall IO.
Today - we specify the PCTFREE 0 clause in every CTAS - so that Oracle won't use the default.
Is there a way to make the default "0" database wide so that we have one less clause to specify?
Thanks !

They really are Global Temporary Tables in functionality - they are part of a daily ETL cycle - but the users would like for them to stick around for 24 hours for "after the fact" analysis of issues - being able to step through table after table - long after the session / process are done. Hence - they are DROP/CREATed every day.
No - statistics aren't collected - it takes precious time. There are no indexes - so 99% of the time the tables are Full Table Scanned and the Hash Joined - which the optimizer is sensible enough to chose 99% of the time.
We run Nologging and NoArchivelogging - so we are spared the triple writes (Data/Log/arch) - so Billion row tables are ETLed very quickly on the modest hardware we can avail ourselves.
PCTFREE 0 saves space, reduces block count, and speeds up IO - and with tables DROP/CREATED it helps the cause.
Thanks for the tip about inheriting PCTFREE from the tablespace. I'll check it out.

If they have a user name and password to your Connect account, and have been assigned Host rights to the room (as well as being in the Meeting Host group if you are using the Named Host licensing), then yes.

EBS R12 Database Copy or clone - init.ora, and spfile conflict...

Hi All,
I am a report developer. I have two servers(VMs)
Server1: Win 2008, Oracle EBS R12.1.1. (db_name = vis)
Server2: Win XP SP3, Oracle 11g R1 (db_name = orcl)
My goal is to copy the whole EBS R12.1.1 Vision Instance database (VIS) on Server1 to Server 2 Oracle Database....And please note that I need only data in those schemas - I use that to run ETL scripts, so, on Server2 I am not going to run any EBS Applications(Forms, or reports or others).
In order to do this I am http://www.dba-oracle.com/oracle_tips_db_copy.htm method.
During the process I have encountered an issue - Server1 (VIS) database uses initVIS.ora file as parameter file, where as Server 2 uses SPFILE.ORA as parameter file.
in Step8 we have to copy the init.ora file from EBS R12 to Server2, but this doesn't help me as server2 use spfile.
please give me your suggestions to solve this gap......
Thanks!

Is it possible to make a searchable database in flash?

Hey guys,
I need to create a page on a site that has the ability to search a database of inventory items, but one that searches based on certain selections (such as a maximum and minimum price, size and things like check boxes to choose a shape like round, square etc.. and only should the matching items).
Is this kind of thing possible in flash?
If it is, does anybody know how I would go about doing this - any good tutorials or examples I can use to learn how to do it?
I'd really appreciate any help I can get on this.
Best regards,
Gareth

You can create a form with Flash that can act as the user interface for acquiring the search criteria and displaying the results, but Flash itself cannot query a database. For that you will need to introduce a server-side script, such as PHP, to do the work of querying the database and returning the search results. YOu should search Google using terms like "AS3 PHP MySQL tutorial"

Is it possible to make an .exe file in Forms 6i

Dear Sir,
I have some doubts regarding some of the Oracle Products.
1. Is it possible to make .exe file in Oracle Forms 6i ?
2. In Oracle 7.3 / Forms 4.5/ Reports 2.5, it was necessary to install Oracle Enterprise at the server and install forms and reports runtime at the nodes. What is the case with Oracle 8i and Forms 6i and Reports 6i.
Do we need to install the runtime at the nodes.
3. If I develop a software using D2k (Forms 6i/Reports 6i) using Oracle 8i, what is required at the client's place to run it. Do they need to buy Oracle 8i as well as D2k(in full) or D2K Runtime is seperately available?
Please reply to the above queries. Thanking you
Sambaran Datta

- You cannot create a single exe file for Forms. You will have to install the runtime and then deploy the application fmx files.
To deploy, you will need to install the Forms runtime on each machine which will be running forms. So if you are running client server and you have 100 client machine you would do 100 installs. Alternatively, if you are installing on the Web then you install the runtime on a server and your 100 clients only need to connect from browser.
I'm not sure how the licencing sales are worked out - your account manager would have a better idea but you don;t have to have an 8i for every client (!) - the Forms runtime and the database are separate.

Is it possible to install Oracle 10g database on a linux Os ?

Hello all,
I recently installed Fedora 14, and oracle 10g free edition, on my modest laptop.
Problem is , I can't upload any scripts, because as i recently learnt from my school teacher, Oracle only works smoothly with Internet explorer browser (i.e.).
I tried using programs like winetricks to download a linux version of i.e. but in this case Oracle doesn't even open its homepage.
-In a nutshell, does anyone know a possible way to work with oracle 10g , (or any alternative), that's fully functional on linux (fedora 14) ? Download, Install steps,etc.
All i need to do is upload simple SQL scripts, and practice my " select from...." commands.
-Is oracle linux a option ? and what is it?
Thank you already for any replies, I'm really getting tired of googling threw different forums.

Ed,
-i knew my teacher was being stubborn;
-I meant that the winetricks version of i.e., didn't open the homepage of oracle 10g (=log in screen).
-what i was trying to do was, after having installed oracle 10g , "go to data base homepage" (openend by firefox) , once logged in with my username, upload a script , and practice typing the different (select from ...group by..etc) sql commands.
Here is one of several concepts you need to fix in your mind. Databases don't have home pages. Client applications do. Databases store and manage data. Humans at the keyboard see the client application, not the database. Oracle provides some client apps ( iSQLPlus, Oracle Enterprise Manager (Grid Control), dbcontrol, APEX) and even installs some with the database by default, but they are distinctly separate from the database, and so must be identified when talking about user interface issues. Unfortunately, telling us you tried to open "the home page of oracle" tells us nothing at all. If you had said "Tried to log in with iSQLPlus" or "I tried to connect with Apex", it would have conveyed MUCH more information. We would have then had some frame of reference as to what you were seeing.
To the "upload from where" question : I simply copied the scripts ( .sql , file) from the pc's from school, on usb, then copied them on my own system. When using the "upload scripts" option from oracle, Again, you must distinguish between "oracle" (the database) and whatever client tool you use to connect to it. "Oracle" (the database) doesn't have an "upload scripts" option. Some un-named application does.
the script is uploaded, but when i try to "run" it , nothing , blank page. no tables, nada. And given what I've said above, you can guess what this statement means. - grin -
My first guess was, well the teacher said " i.e. only " , so i tried installing i.e. , using winetricks, but i had a feeling i was going off-track, and that surely there must have been a much easier way.
Even Billy was more charitable toward your teacher than I feel. And when he is so wrong about something as simple as this, makes me wonder what else he is wrong about. And the quality of the teachers calls into question the quality of the school in general.
In fact, had I been told that by an instructor, I would make it a personal mission to prove him wrong. Not in front of the class (as much short term satisfaction as that may provide) but just by taking my laptop to his office and saying "let me show you something". One of my personal hot buttons is for someone who should know better to pronounce something as "won't work" when I've been doing it for so long and so easily as to just take it for granted.
>
Linux (fedora 14) is up and running,
oracle 10g , linux version, was installed using detailed guide.
And yes, i will look into oracle linux, and oracle 11g ,
but i was hoping to use the same version as my school, to avoid any surprises when passing my exams.Edited by: EdStevens on Jun 13, 2011 3:02 PM

Is it possible to make connection for the VC application the SQL Server

hi
I have requirement like, We have some data available in SQL server as central repositoty. My client want to make the Anylatics application like showing graphs in VC based on the data available in SQL server.
My question. Is there any possiblity to make the connection the sql server by creating some system object using some JDBC connection Like that.
What is the possibility.
can u any body tell what is the work around need to be for this requirement. Whether it is possible or not.
Regards
vijay

Hi Vijay,
In your other thread, I have given the link to the following doc which will help you to in configuring the JDBC Connector.
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/uuid/b00917dc-ead4-2910-3ebb-b0a63e49ef10
That was the first step.
In the second step, you need to create a JDBC System in the portal. Go through the following doc which explains how to create BI JDBC system for VC. All you need to change is that on Page 10, choose JDBC system instead of BI JDBC system, and do the necessary configurations.
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/6209b52e-0401-0010-6a9f-d40ec3a09424
As rightly said by Marcel, you can use stored procedures as well as SQL statements. As far as stored procedures are concerned, all you need to do is go to Enterprise Manager, and create procedures in your database in the same way by which you create new tables and users (Refer my article). Then you can use these procedures in your Visual Composer provided you have properly created the JDBC system in portal properly.
Also have a look at the following doc:
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/6339e7d4-0a01-0010-1c98-db00e52e989a

It's is possible to make a select from a view?

I don't know if it's possible to make a select of a table-view like V_T5F99FW if it's possible does anybody tell me how can I do?
Thanks a lot,

Hi Rebeca,
You can surely do a selection from a projection and database view but not from a maintenance view.
The selection from a view works like a normal selection only.

Is it possible to make a homogenious copy

Is it possible to make a SAP homogeneous copy from the backup of Oracle DB on HPUX (64 bit) to Oracle on Windows (32 bit) ?
I am planning to make a sand box system on windows from the database backup of ORACLE/HPUX.
Your reply will be highly appreciated
Al Mamun

Hi,
I'd like to clarify a little.
You <b>cannot </b>restore directly an Oracle backup from HPUX to Windows.
As it is a different OS it is called "Heterogeneus" system copy.
If you want to create a sand box, then ( not knwing your DB version ) you will have to export the data with R3load and import it on the new system.
You can find the guide on
http://service.sap.com/instguides
The exact location depends on the SAP Version.
If you are already on Oracle 10, perhaps you can take a look at the note <a href="http://service.sap.com/sap/support/notes/1003028">1003028: Enhanced support for system copy in BR*Tools</a> as it explain a method to use transportable tablespaces for the heterogeneus system copy.

Is it possible to make an alert message.

Hi,
Anyone knows if it Is possible to make an alert-message that pops up ( f.e as a little window) on a specific day to remember me of something I have to do that day?
Would be handy.
Is this possible with Tiger or is there a third party application that does the trick?
Thanks in advance.

Is it possible to make a copy of the Leopard install DVD?

Is it possible to make a copy of the Leopard install DVD? If so, is there a special way this has to be done? I just found out that we needed to use the Leopard install DVD to recover a complete backup from Time Machine after a recent hard drive failure. We have the family pack of Leopard, so I would like to keep the original at home and send a copy when my daughter goes off to college in case she needs to recover again. Her machine was originally a Tiger MacBook, so those install disks will not work. If it is not possible to copy the DVD, is there a way to create a bootable utility to do a time machine recovery?

This half-solved my problem. I have had no problems creating a backup copy for my intel based computers, but non-intel based computers are problematic; a G5 powermac tower and a G4 Powerbook. Both with super drives for single density burning. Both have Leopard running, installed from an install disc purchased from Apple. However, neither will mount the copy, but intel based computers will. have burnt/burned with both toast 9 and Disc Utility. Discs won't mount and are "spit out" by the drive.
Power Mac G5 OS X: 10.5.4
Model Identifier: PowerMac7,3
Processor Name: PowerPC G5 (3.0)
Processor Speed: 2 GHz

Hello SMEvans32
You can use iCloud to share the Calendar, that way she will always be up to date on that particular section of your work calendar. If you want to use iCloud, I would recommend backing up so you have a safe copy of your data.

Top-Level Navigation Bar - Is it possible to make it 3 levels?

Dear Portal Experts,
Could someone please advise if it is possible to make the Top-Level Navigation Bar show more than 2 menu levels? I looked at the document and it said we can only have 1 or 2 levels. But I'm just wondering if there is any way around it. Thanks.

yes you are right .we can set only 1 0r 2 levels but good news is there is a workaround

Is it possible to make a type cast in TestStand?

I've got the following problem.
I use a receive function which waits for an undefined package. (struct package).
The problem is i can't specify the module with the exaxt package.
Generally in C i define a Pointer and create enough buffer for it. Is it the same in TestStand?
Is it possible to make a type cast?
for example:
i've got these packages
struct packet;
struct data;
the function does not know which structure to receive.
err = receive(buffer,maxlen);
how do i specify the buffer variable?
can i create a type "void" with a String to have enough buffer.
and then to make a type cast, for example "Locals.dataobject = ((data)Locals.buffer)"
any ideas?
thx for help

Unfortunately there is no way to do type-casts in TestStand. What you could do is write a wrapper-dll in C, that has for example two parameters for both possible structs. The dll then takes one of the parameters, does the typecast and passes it on to your original dll.
From TestStand you can pass the struct(or better container in the "TestStand language") you want to use to the accoridng parameter of the wrapper-dll, leaving the other parameter empty or with some default-value.
Hope this helps!
