Daylight savings effect - Oracle AS 10g r2 on AIX

Hello,
Could someone please list the effects of daylight savings on Oracle AS 10g r2 on AIX. I wasn't able to find any documentation on the web that helps. If anyone has a link to online documentation on this topic, it would be great if you can share it.
Thank you,
Rev

So far I haven't been able to find any abonaolies besides some wierd timestamps in logging.
What side effects are you worrying about?

2007 Daylight savings time - Oracle 9.2

Hi All,
My Oracle database runs on Windows 2000 Advanced Server. I have followed Microsoft instructions to update the Daylight Savings Time to new settings. Given this, will I need to apply Oracle patches ?
Thanks for your help,
P.

You will need to patch Oracle, check this blog for more info.

Oracle db 10gR2 installation on AIX 5 series server

can anyone please suggest me a gud link to get detailed steps for installing oracle database 10g R2 on AIX server as I am completely new to AIX.
I have done db admin and maintainence on Solaris and Linux, though.
Please also suggest gud installation guide for Oracle Application server 10g R2 forms and services only.
thanks in advance!

Daylight savings time? Oracle has ignore?

it has some command DBA that the Oracle 9i can ignore the Daylight savings time in the calculations with dates?
thanks.

I have following procedure:
procedure CREATE_STOCK_DATA_SCENA () is
next_day date;
n_days number;
begin
create table TEMP_GRAF_ESTOQ
DATA DATE not null,
-- continue
delete from temp_graf_estoq;
-- it generates 100 days from today on
next_day := sysdate;
n_days := 0;
while (n_days < 100)
loop
insert into temp_graf_estoq
(data)
values
(next_day);
next_day := next_day + numtodsinterval(1,
'DAY');
n_days := n_days + 1;
end loop;
/*** continue ****/
end CREATE_STOCK_DATA_SCENA;
In the output, when it was to generate the last day of the October month as 31, it is generated 30. I believe that it is for cause Daylight savings time.
Somebody already passed for this problem or something seemed?
Thanks

32 Bit Installation or Oracle Linux and Oracle Database 10g

I have an old E-Machine that I wanted to put Oracle Linux and Oracle Database Express 11G on. I was just wanting to do some testing and development on the system. I'm pretty sure the machine is 32bit.
I just burned a copy of 32 bit Oracle Linux onto a CD. Is there a version of Oracle Database Express that will run on it?
It seems like there is only a 64 bit version of Oracle Express Database 11g. Is Oracle Database Express 10g installable on Oracle Linux 32 bit?
Let me know! Thanks in an advance.

One (or two) caveats with the 10g version, XE can not be patched and the 10.2.0.1 XEs were created before the current daylight savings time rules went into effect.
If you have access to My Oracle Support there is a method to get updated timezone files for the oracle binaries, you need at least version 4 of the DST files. I've got the MOS docIDs somewhere let us know if needed and I'll dig 'em up.

Daylight savings in infoview

Hi,
Crystal Reports show the standard time, not daylight savings time in Infoview only. The OS and Oracle database both show daylight savings time. Also, the CMC shows the daylight savings.
Please let me know if you have the solution for this issue.
Thanks,
Hao

Hello,
Have you looked into using the formula function "ShiftDateTime" to address the daylight savings time challenge you're looking at?
Here's an excerpt on how to use this function.
Example
The following example is applicable to both Basic and Crystal syntax:
ShiftDateTime (DateTime (2000, 1, 1, 12, 0, 0), "EST,300,EDT", "PST,480,PDT")
Returns 1/1/2000 9:00:00AM
In this example, noon Eastern Daylight Time is shifted to 9 am Pacific Daylight Time.
Syntax                Description
std                       String name of the standard time zone.
offset                  Offset, in minutes, of the standard time zone (west is positive).
dst                       String name of the DST time zone.
offset                  Optional DST offset from standard (defaults to one hour ahead of standard offset).
start                    Date when DST goes into effect. The format is m.w.du2014representing the month, week, and day number of the date. w=1 is the first week of the month, and w=5 is the last week of the month.
time                      Optional time that DST goes into effect (24-hour clock). The default is 02:00 (local to the given time zone).
end                      Date when time zone changed back to standard
(Sorry for the formatting of the post - copy/paste out of the CRW help for shiftdatetime didn't work very well)

IdM Scheduler and Time Change to Daylight Savings Time GMT to BST

This isn't really a 'question' , but just a topic for discussion.
We're not live yet, but will be by the time the clocks go back. So I'm just interest to hear everyone's experiences and any issues with regards to the switching to / from DST
I did some "interesting" (or not) tests last night to see what happens with Pending Values which are due to take effect at the time change threshold of 01:00 GMT when switching to Daylight Savings Time (BST) GMT +0100.
It seems as if the IdM scheduler keeps going according to UTC or GMT. However any values provisioned to target systems or to local tables using the ddm.datetime8601 system variable are in local time according to the runtime server or SQL server's locale settings.
I set up a task to output from a javascript the current system date
using the following in the functions.
currentTime = new Date();
return currentTime.toString(); // returns Locale Time String
currentTime = new Date();
return currentTime.toUTCString(); // returns UTC Time String
in the same pass I also output the ddm.datetime8601 system parameter and the ddm.time24 system parameter.
This task was to update a comment on an entry and Scheduled to run at 00:00:00 and was executed at 00:00:06 GMT all times were still in GMT as expected.
Local Time: Sun Mar 27 00:00:06 GMT-0000 (GMT) 2011, UTC Time: Sun, 27 Mar 2011 00:00:06 GMT, ddm.datetime8601: 2011-03-27T00:00:06, ddm.time24: 00:00:06
This task was scheduled at 01:00:00 in IdM and was exectued at 01:00:08 GMT by the runtime, and you can see the local time is being correctly reported as 02:00:08 BST. Note also the ddmdatetime8061 is also 02:00:08 i.e. BST.
Local Time: Sun Mar 27 02:00:08 GMT+0100 (BST) 2011, UTC Time: Sun, 27 Mar 2011 01:00:08 GMT, ddm.datetime8601: 2011-03-27T02:00:08, ddm.time24: 02:00:08
In the database the entry values MXI_VALUES ModifyTime field has the GMT / UTC timestamp.
I also set up some pending value objects to be applied at 00:59:59 and 01:30:00 to see if the 01:30:00 would be 'skipped' as the locl clock change would've gone from 00:59:59 to 02:00:00. Well the pending values were correctly applied and expired and no 'lost' transactions happened as a result of the change.
So essentially it seems to me that the IdM runtime and scheduler times are all based on UTC / GMT.
I guess it's only an issue twice a year if you're expecting something to happen at a specific local time 01:00:00 or if you've got a global user base and their account expiry should be in each user's own country's local time. In these cases, it would seem that you'd need to convert the schedule times and pending value times to UTC first before setting them in the database.
Has anyone else had any issues, thoughts, questions or suggestioins on scheduling tasks which span the DST time change when switching to and from Daylight Savings Time.

Exception [TOPLINK-46] (OracleAS TopLink - 10g (9.0.4) (Build 031126))

Hi,
I am using TopLink for simple Department-Employee relation, i have my project xml configured, But i am facing the problem with following exception
Descriptor Exceptions:
Exception [TOPLINK-46] (OracleAS TopLink - 10g (9.0.4) (Build 031126)): oracle.toplink.exceptions.DescriptorException
Exception Description: There should be one non-read-only mapping defined for the primary key field [emp.empno].
Descriptor: Descriptor(com.oracle.mssql.emp.toplink.EmpTopLinkBean --> [DatabaseTable(emp)])
Runtime Exceptions:
What could be the reason?
Thanks
Madhu

My best guess would be that you have a 1:1 mapping from Employee to Department. This mapping represents part of the primary key.
Make sure that your 1:1 mapping is not configured as read-only. Another issue is that you may have set the relationship as target foreign key. This has the same effect as read-only and is not applicable in the 1:1 returning from a 1:M.

Doubt with Windows and Oracle Forms 10G and 11g

Hi
I have some doubts in installing Oracle Client on Windows.
a)Can we install Oracle Forms 10g and Reports 10g client on Windows 7?
b)Can we install Oracle Forms 11g and Reports 11g client on Windows XP?
c)If we have an Oracle Forms 11g and Reports 11g, can it connect to a 10g Server?
d)If we have an Oracle Forms 10g and Reports 10g Client, can it connect to an 11g Server?
Please, Can any one help me in this????

a)yes it can be installed on win7, may have some issues on 64bit systems but they're solvable
b)11g had some problems with windows 2000, but didn't see mention of any problems on XP
c)if you mean a database server then yes - i managed to connect 11g to an 8i database, so v10 should not be a problem. If you mean a forms/reports server..well newer forms/reports builder might not want to run old forms/reports and vice versa, but I don't see the point of operating on the same files from different versions. You can still load old form/report source files with a newer builder and recompile them to run on the new server.
d) the "client" is effectively your web browser with a java plugin, unless I misunderstood your question. What version was a form/report compiled with should not be an issue.

Oracle 11G,10g and DB2 replication?

Oracle 11G,10g and DB2 replication?
=======================================
We are using Oracle 11gR2. We have a table in Oracle filled with partial data (over 200K+, it may grow to 1M). The rest need to be obtained from DB2. It is not from one DB2 table.
The DB2 is configured to run Oracle 10g within it. We have given http interface, where we need to supply(Push) the partial data using HTTP_UTIL package for each row, then DB2/Oracle 10g return the result as XML.
It is a network heavy, slow and not reliable.
Are we able to replicate tables between Oracle 11g and DB2/oracle 10g?
We like to leverage the features on 11gR2 effectively.
I find some interesting folks in this forum.
Did anyone face such situation?
I like to know the best approach with good performance options.
Any idea?
Thanks in helping.

why is DB2 required to produce XML?

2007 Daylight Savings

Does anyone know if the change in the way daylight savings times start and stop will have any effect on Discoverer? We're using Discoverer 4. Is there any settings that need to be changed in Discoverer, or will operating system patches be enough for the change? I really have no idea if Disco will be affected at all, just want to ask to be safe.
Thanks

Hi there,
I’ve never really thought about this either but from my experience with Discoverer 4, we haven’t had any problems with the change in time due to daylight savings. I assume that as long as the Server hosting Discoverer has the correct time you’ll be ok as discoverer uses the Server time instead of the local clients time.
You could however test this in a development environment by setting the server’s clock and by running a few reports that have been saved in the DB or scheduled. Once run you can confirm the results and time within the EUL scheme statistics tables. Do this before and after the daylight settings and record your results. In the end you can do a comparison and see if it had any impact.
Unfortunately I haven’t got access to discoverer at the moment, but would be grateful if anyone that has tested this could share their results.
Many thanks,
Lance

2007 Daylight Savings Time Changes

What, if any, effects will the 2007 changes to US daylight savings time have on the operation of the LabVIEW 7 Express development environment and deployed applications created with it?

I believe the answer depends on the OS the application runs under.
If MS has there act together and the machine in question has recieved updates, there should be no issue.
If you are running Unix (or a variation o such), a patch must be applied (at least that was the story my wife gave for working all night Saturday night).
I can not answer this Q for Mac or LV-RT running under Pharlap.

JDev log times and Daylight Savings

Nothing major.
I've noticed that the log messages appearing in JDev are not respecting my daylight saving time. Log times are appearing as 1 hour earlier than my computers time.
My platform is WinXP with Western Australian Daylight Savings patch applied.
e.g. at 14:14:56
3/02/2007 13:14:56 oracle.jsp.logger.JspMessages infoProviderURIUsed
INFO: Using the ProviderURI /mdssys/ViewController/public_html/MyContent.jspx that is returned from custom provider for processing requests.
3/02/2007 13:15:23 oracle.jsp.logger.JspMessages infoProviderURIUsed
INFO: Using the ProviderURI /mdssys/ViewController/public_html/MyContent.jspx that is returned from custom provider for processing requests.

As a matter of interest, do you get the same when if using JDK 1.5.0_07
If you've Metalink access, see Note 397281.1
Also, see: JDeveloper 10.1.3.1 Daylight Savings Time patch

If you haven't already, you can also post discussions to the JDeveloper forum:

COREid and Daylight Savings Time for 2007

Do COREid or any of its components require any special fix in order to comply or function properly with the new Daylight Savings Time for 2007?
Background:
In August of 2005 the United States Congress passed the Energy Policy Act,
which changes the dates of both the start and end of daylight saving time
(DST). When this law goes into effect in 2007, DST will start three weeks
earlier (2:00 A.M. on the second Sunday in March) and will end one week later
(2:00 A.M. on the first Sunday in November) than what had traditionally
occurred.
Thanks,
Craig

We have experienced many problems with DST and COREid in the past; most of them resulting in hung Access server and unavailability. I don't know if it's because we have components distributed across multiple time zones or what. Our plan is to have someone available at the time change to cycle the services (and maybe the server as a whole) and do a health check after the fact. I hope this helps.

BI GRAPHS IN ORACLE FORMS 10G

AFTER FINDING SOLUTION TO MAKE GRAPHS CUSTOMIZATION IN ORACLE FORMS 10G, I was suggested to use BIGRAPH so installed all package(formsgraph.jar and whole demo package) and I configured properly all my files. But graph.fmx which exist in demo when run on browser does not display any graph on bean area it might be as no data retreived or data not populated due to bug in fmb . I made new temp.fmb by only creating single item and bean on canvas. On validating item I wrote following syntax.
BEGIN
     IF (:BLOCK1.TEXT_ITEM5 = ' ') THEN
     message('validating');
     set_custom_property('block1.BeanArea1',1,'GRAPHTYPE','HORIZONTAL_BAR');
set_custom_property('block1.BeanArea1',1,'ENABLE_TOOLTIPS','ALL');
SET_CUSTOM_PROPERTY('block1.BeanArea1',1,'SET_DELIMITER',',');
SET_CUSTOM_PROPERTY('block1.BeanArea1',1,'ADD_ROWDATA','Europe,Sales,25000');
SET_CUSTOM_PROPERTY('block1.BeanArea1',1,'ADD_ROWDATA','USA,Sales,70000');
SET_CUSTOM_PROPERTY('block1.BeanArea1',1,'ADD_ROWDATA','Europe,Taxes,2500');
SET_CUSTOM_PROPERTY('block1.BeanArea1',1,'ADD_ROWDATA','USA,Taxes,2500');
SET_CUSTOM_PROPERTY('block1.BeanArea1',1,'ADD_ROWDATA','Europe,Savings,22500');
SET_CUSTOM_PROPERTY('block1.BeanArea1',1,'ADD_ROWDATA','USA,Savings,67500');
SET_CUSTOM_PROPERTY('block1.BeanArea1',1,'ADD_DATA_TO_GRAPH','');
SET_CUSTOM_PROPERTY('block1.BeanArea1',1,'ADD_ROWDATA','UK,Taxes,67500');
set_custom_property('block1.BeanArea1',1,'SHOW_GRAPH','');
     END IF;
END;
Still surprise as forms open successfully on Web browser but no chart displayed. I am really fade up as I required lot of time to install demo version in my original oracle 10g software. My boss say how can new version have no features of graphics. I can not tell or say to buy that oracle graphics are customized in Oracle 11g.
If anybody have solution for above, please reply.
Thanks,
Prashant

Hello Omama,
Problem of Bi Graphs have been solved by running url with extension as config=Bigraph. For my next problem in graph of 10g I am going to post new thread as BI Graphs does not serve my problem. Anyway Thanks.
