Suggest a new feature. ^-^

Hi all:
I hope ORACLE has such a new feature, to reduce the client codes. We usually do that: Inserting a record to a table, if some columns have existed, then update it, else insert this new record. I assume this statement is:
INSERT INTO MYTABLE (A,B,C) VALUES (1, 2, 3) UPDATE EXISTS (A, B)
It's mean that if A and B is duplicated (exists a row that A=1 and B=2), then UPDATE column C value of these rows to 3 implicitly.
let me know your ideas about it. thanks!!!

Maybe on missed on this ...
Use this forum for feedback about OTN programs, Web site content, and systems -product-related questions cannot be answered here.
and another one gone

How to a make a suggestion about new features i'd like to see in itunes

how to a make a suggestion about new features i'd like to see in itunes?
I can't find any link to do this. I found a page where you can request songs or an album to be added, but i can't find a page to submit my suggestions for itunes i have for new features i'd like to see

As of now there is no good, direct link for feedback on iTunes itself. Writing Apple might be the best option, with the website feedback page perhaps the next best.

Current Firefox versions have a feature called tear-off tabs. 
You can detach a tab from the current window and open it in a new window by dragging a tab in the browser window. 
You can drag that tab back to the tab bar in the original window to undo that detaching.

Question regarding suggestion of new features

I'm probably going to touch on a sensitive topic, but please hear me out. In working with some legacy systems and I have the need to deal with unsigned values. Needless to say this is difficult to do in Java. There are some work around solutions, but they are hardly ideal. I would like to suggest this feature be added to the language. The question I have is how do I go about suggesting a new feature and get the ball rolling? Is it as simple as forking and developing it all yourself hoping it gets merged in or does it mean you have to go through the JCP?
Thoughts?

you still havent shown that you NEED unsigned ints.
That's kind of an odd statement. Let me see if I'm hearing you right. I don't NEED unsigned ints because I can always cast them up to longs, etc and handle them that way? Does the fact that one is not the other play a role? Say like I were to commit that back to a database (or worse, a binary file). I'd have to always do some conversion and handle an overflow possibility because I'm treating it as a long...
also, there might be another good reason beyond the fact that they arent really necessary:
the java opcodes were made to fit into a byte.
as it is now, a lot of those opcodes are used
for primitive conversions and every permutation of primitive arithmetic.
if they added 4 more primitives to the existing 6...Couldn't that statement apply to any language addition? "I'm sorry I shouldn't do it because I've only got a byte and need to save it for more useful stuff."

Creating a conditional index? How to suggest a new feature?

How can I suggest a new feature in Oracle?
Imagine a table of service requests to be processed, where a column named STATUS can be: 'N': New, 'C': Canceled or 'P': Processed. This will result in a biased distribution where 'P' will represent more than 99% of rows.
I know that Oracle accept indexes created using functions and I can create an index on decode(STATUS,'P',null,STATUS) to make index small. But it will not help a query on STATUS = 'N' condition.
I would like to create a conditional index like:
create index idx01 on service_requests (status) where status <> 'P';
In this example, only status 'N' and 'C' will be indexed resulting in a very small index that can resolve filters like STATUS = 'N'.
Or this:
create index idx01 on some_tables (column1 including null values); to resolve COLUMN1 is NULL
Is there a way to suggest new features like this?

A new feature isn't needed. Oracle provides the equivalent of that 'conditional index' by allowing you to create, and index, VIRTUAL columns.
This code uses a VIRTUAL column and then creates an index on it.
drop table test_status
create table test_status (col1 number,
status varchar2(1),
special_status generated always as (decode(STATUS,'P',null,STATUS)
create index idx01 on test_status (special_status)

Suggestions for new features & improvements to LCCS/ICS service

Firstly Hello, I am James from Influxis. if you got a suggestion for a possible improvements or new features to LCCS/ICS feel free to add your suggestions below and we look into it.
Thanks,
James

Hi James,
With the offering from Adobe, it was possible to have a free account with $15/month of service offered.
It was really useful to developp applications, or to make demos applications for clients, and then paying when the application takes off only.
Does Influxis plan to offer something similar?

Suggestions for new features

I don't know, if this forum is monitored by the development staff, but I'll post my suggestions here in case they do.
I would be nice to have optional ballon-tips when a new song is played.
I would also be nice, to have some icons in the context menu of the taskbar-icon for play, next song, previous song.
cheers
Bernhard

well i would very much like to see a check box in the edit info that allows you to add a file from a podcast into your main music library in your ipod. i find it rather frustrating to see that i have 2 seprate file librarys now.

Suggestion for new feature

I am sure two features commonly available in dj programs like Traktor and Mega Seg would make iTunes even more usable.
#1 Variable tempo and pitch controllers.
#2 A automatic beat counter
I run a dance school/nightclub and except for these features I would use iTunes exclusively for teaching annd djing

I suggest you make your comments known to apple...

Suggestions for new features and improvements for Garageband

Hi,
I posted this to iCompositions but don't know who would be exposed to it as far as Apple goes. Just thought I would list a sort of wish list for GB that would make a huge difference for me.
Most are just basic interface improvements and changes. Some you may already be able to do and I'm unaware.
1. A click track option would be nice.
2. A space to write production notes as in guitar used and pickup used.
3. A Telecaster and Strat icon for the track icons.
4. When you duplicate a track it also duplicates the region(s) of the track.
5. An edit (highlight) button on a region to mark where editing needs to happen. This could be saved for future reference and quick navigation to.
6. More control over the loop button on tracks. If you want to move it to another section it ***** to get at both ends and drag it to where it needs to be.
7. Audio Interface volume booster. I don't get the same input from my M-Audio Ozone as I do via input of my guitar through a direct box. Not even close. Maybe it's my interface?
8. More than one effect(s) on the same track.
This is my wish list.
ej
G5 Mac OS X (10.4.9) PowerPC G5 Dual 2 GHz 1GB SDRAM

First of all, if you want Apple to listen to your suggestions, you better use the feedback forms, since this is a user forum and is very rarely visited by Apple employees.
As for your list: People in this forum have put together a huge wishlist which somehow differs from yours (see this thread, for example). Top of the list are midi export, variable tempo and volume and effect automation.
As for your no.8:
8. More than one effect(s) on the same track.
You can have up to 4 effects on each track (plus the not very effective compression slider), 2 of them are restricted to echo and reverb.

Suggestion for new features

1. Would it be possible to have the ability to cancel an outgoing message after pressing the send button. For instance, before the bar fully loads thru and the message is sent? Regular cell phones are available to do that, why not the iPhone?
2. For e-mails, I think the feature to add a request for "Read receipt" and/or "Delivery receipt" would be great, similar to a feature available from using Microsoft Outlook.
Hope to hear feedback from anyone, maybe get the attention of Apple staff.

Where to suggest new features for firefox!

Hi,
Is there anywhere to suggest new features for Firefox?
Thanks

Yes - use the Feedback page.
https://input.mozilla.org/en-US/feedback

New feature suggestion for finder.

I'm not sure where one posts new feature ideas/requests so I'll try here first... If you have a better place please tell me.
Please add the Quick Look feature to file selection dialogs.
This is where the feature is at it's most useful. For instance, when selecting files to attach to an email, being able to quick look to make sure it's the version I want to send would be very valuable.
Thanks

No harm in alerting people to new capabilities...

Follow-up to archived thread "Another Error (I think) In the 12.1 New Features Guide"

I hoped to be able to add a reply to the most recent reply on March 8 in the "Another Error (I think) In the 12.1 New Features Guide" thread (https://community.oracle.com/thread/3526588), but since that thread has been archived, I am doing what was suggested elsewhere: create a new thread referencing the old one. My reply is:
Thank you for your explanation about preferring PDF over HTML. That is perfectly fine and understandable. Also, we very much appreciate your documentation feedback in this forum, and encourage you to continue to report any issues here.
I apologize for not replying much sooner. I either didn't get or overlooked an original notification about "Recent activity" after your reply; otherwise, I would have replied then.

Thanks for that comment. I have sent a pointer to it to the writer for that book. Note that with the New Features Guide, most of the content is automatically drawn from an internal system that tracks projects and features; so if a change is needed, the writer will notify the owner of that content (typically a developer or a product manager) to investigate and (if necessary) modify the underlying data, after which the changed information will be picked up for a future revision of the book.
Also, while anyone is welcome to enter documentation comments in this forum, another option that may be more convenient for comments on specific sections is the Reader Comment area at the bottom of each HTML page (such as http://docs.oracle.com/cd/E16655_01/server.121/e17906/chapter1.htm#NEWFT495 for the page containing Section 1.5.9.8). Any comments entered in a Reader Comment area go to someone in our documentation production group, who forwards them to the appropriate writers.
However, if a comment involves multiple HTML pages or books, or if you want the matter to be in a public forum for visibility and searchability, posting in this forum is a good option.

Oracle 10G New Feature........Part 1

Dear all,
from last couple of days i was very busy with my oracle 10g box,so i think this is right time to
share some intresting feature on 10g and some internal stuff with all of you.
Have a look :-
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Oracle 10g Memory and Storage Feature.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1.Automatic Memory Management.
2.Online Segment Shrink
3.Redolog Advisor, checkpointing
4.Multiple Temporary tablespace.
5.Automatic Workload Repository
6.Active Session History
7.Misc
a)Rename Tablespace
b)Bigfile tablespace
c)flushing buffer cache
8.ORACLE INTERNAL
a)undocumented parameter (_log_blocks_during_backup)
b)X$ view (x$messages view)
c)Internal Structure of Controlfile
1.Automatic memory management
================================
This feature reduce the overhead of oracle DBA.previously mostly time we need to set diff oracle SGA parameter for
better performance with the help of own experience,advice views and by monitoring the behaviour
of oracle database.
this was just time consuming activity.........
Now this feature makes easy life for oracle DBA.
Just set SGA_TARGET parameter and it automatically allocate memory to different SGA parameter.
it focus on DB_CACHE_SIZE
SHARED_POOL_SIZE
LARGE_POOL
JAVA_POOL
and automatically set it as
__db_cache_size
__shared_pool_size
__large_pool_size
__java_pool_size
check it in alert_log
MMAN(memory manager) process is new in 10g and this is responsible for sga tuning task.
it automatically increase and decrease the SGA parameters value as per the requirement.
Benefit:- Maximum utlization of available SGA memory.
2.Online Segment Shrink.
==========================
hmmmmm again a new feature by oracle to reduce the downtime.Now oracle mainly focus on availablity
thats why its always try to reduce the downtime by intrducing new feature.
in previous version ,reducing High water mark of table was possible by
Exp/imp
or
alter table move....cmd. but on these method tables was not available for normal use for long hrs if it has more data.
but in 10g with just few command we can reduce the HWmark of table.
this feature is available for ASSM tablespaces.
1.alter table emp enable row movement.
2.alter table emp shrink space.
the second cmd have two phases
first phase is to compact the segment and in this phase DML operations are allowed.
second phase(shrink phase)oracle shrink the HWM of table, DML operation will be blocked at that time for short duration.
So if want to shrink the HWM of table then we should use it with two diff command
first compact the segment and then shrink it on non-peak hrs.
alter table emp shrink space compact. (This cmd doesn't block the DML operation.)
and alter table emp shrink space. (This cmd should be on non-peak hrs.)
Benefit:- better full table scan.
3.Redolog Advisor and checkpointing
================================================================
now oracle will suggest the size of redo log file by V$INSTANCE_RECOVERY
SELECT OPTIMAL_LOGFILE_SIZE
FROM V$INSTANCE_RECOVERY
this value is influence with the value of FAST_START_MTTR_TARGET .
Checkpointing
Automatic checkpointing will be enable after setting FAST_START_MTTR_TARGET to non-zero value.
4.Multiple Temporary tablespace.
==================================
Now we can manage multiple temp tablespace under one group.
we can create a tablespace group implicitly when we include the TABLESPACE GROUP clause in the CREATE TEMPORARY TABLESPACE or ALTER TABLESPACE statement and the specified tablespace group does not currently exist.
For example, if group1 is not exists,then the following statements create this groups with new tablespace
CREATE TEMPORARY TABLESPACE temp1 TEMPFILE '/u02/oracle/data/temp01.dbf'
SIZE 50M
TABLESPACE GROUP group1;
--Add Existing temp tablespace into group by
alter tablespace temp2 tablespace group group1.
--we can also assign the temp tablespace group on database level as default temp tablespace.
ALTER DATABASE <db name> DEFAULT TEMPORARY TABLESPACE group1;
benefit:- Better I/O
One sql can use more then one temp tablespace
5.AWR(Automatic Workload Repository):-
================================== AWR is built in Repository and Central point of Oracle 10g.Oracle self managing activities
is fully dependent on AWR.by default after 1 hr, oracle capure all database uses information and store in AWR with the help of
MMON process.we called it Memory monitor process.and all these information are kept upto 7 days(default) and after that it automatically purge.
we can generate a AWR report by
SQL> @?/rdbms/admin/awrrpt
Just like statspack report but its a advance and diff version of statspack,it provide more information of Database as well as OS.
it show report in Html and Text format.
we can also take manually snapshot for AWR by
BEGIN
DBMS_WORKLOAD_REPOSITORY.CREATE_SNAPSHOT ();
END;
**The STATISTICS_LEVEL initialization parameter must be set to the TYPICAL or ALL to enable the Automatic Workload Repository.

Benefit:- Now DBA have more free time to play games.....................:-)
Advance version of statspack
more DB and OS information with self managing capabilty
New Automatic alert and database advisor with the help of AWR.
6.Active Session History:-
==========================
V$active_session_history is view that contain the recent session history.
the memory for ASH is comes from SGA and it can't more then 5% of Shared pool.
So we can get latest and active session report from v$active_session_history view and also get histortical data of
of session from DBA_HIST_ACTIVE_SESS_HISTORY.
v$active_session_history include some imp column like:-
~SQL identifier of SQL statement
~Object number, file number, and block number
~Wait event identifier and parameters
~Session identifier and session serial number
~Module and action name
~Client identifier of the session
7.Misc:-
========
Rename Tablespace:-
=================
in 10g,we can even rename a tablespace by
alter tablespace <tb_name> rename to <tb_name_new>;
This command will update the controlfile,data dictionary and datafile header,but dbf filename will be same.
**we can't rename system and sysaux tablespace.
Bigfile tablespace:-
====================
Bigfile tablespace contain only one datafile.
A bigfile tablespace with 8K blocks can contain a 32 terabyte datafile.
Bigfile tablespaces are supported only for locally managed tablespaces with automatic segment-space management.
we can take the advantage of bigfile tablespace when we are using ASM or other logical volume with RAID.
without ASM or RAID ,it gives poor response.
syntax:-
CREATE BIGFILE TABLESPACE bigtbs
Flushing Buffer Cache:-
======================
This option is same as flushing the shared pool,but only available with 10g.
but i don't know, whats the use of this command in prod database......
anyway we can check and try it on test server for tuning n testing some query etc....
SQL> alter system flush buffer_cache;
System altered.
++++++++++++++++++
8.Oracle Internal
++++++++++++++++++
Here is some stuff that is not related with 10g but have some intresting things.
a)undocumented parameter "_log_blocks_during_backup"
++++++++++++++++++++++++
as we know that oracle has generate more redo logs during hotbackup mode because
oracle has to maintain the a complete copy of block into redolog due to split block.
we can also change this behaviour by setting this parameter to False.
If Oracle block size equals the operating system block size.thus reducing the amount of redo generated
during a hot backup.
WITHOUT ORACLE SUPPORT DON'T SET IT ON PROD DATABASE.THIS DOCUMENT IS JUST FOR INFORMATIONAL PURPOSE.
b)some X$ views (X$messages)
++++++++++++++++
if you are intresting in oracle internal architecture then x$ view is right place for getting some intresting things.
X$messages :-it show all the actions that a background process do.
select * from x$messages;
like:-
lock memory at startup MMAN
Memory Management MMAN
Handle sga_target resize MMAN
Reset advisory pool when advisory turned ON MMAN
Complete deferred initialization of components MMAN
lock memory timeout action MMAN
tune undo retention MMNL
MMNL Periodic MQL Selector MMNL
ASH Sampler (KEWA) MMNL
MMON SWRF Raw Metrics Capture MMNL
reload failed KSPD callbacks MMON
SGA memory tuning MMON
background recovery area alert action MMON
Flashback Marker MMON
tablespace alert monitor MMON
Open/close flashback thread RVWR
RVWR IO's RVWR
kfcl instance recovery SMON
c)Internal Structure of Controlfile
++++++++++++++++++++++++++++++++++++
The contents of the current controlfile can be dumped in text form.
Dump Level Dump Contains
1 only the file header
2 just the file header, the database info record, and checkpoint progress records
3 all record types, but just the earliest and latest records for circular reuse record types
4 as above, but includes the 4 most recent records for circular reuse record types
5+ as above, but the number of circular reuse records included doubles with each level
the session must be connected AS SYSDBA
alter session set events 'immediate trace name controlf level 5';
This dump show lots of intresting information.
it also show rman recordes if we used this controlfile in rman backup.
