SQL & PL/SQL :: Local Timezone With Day Light Saving Time?
Oct 22, 2011
Order time is not properly displayed in the local timezone format and day light saving calculation is also another issue. Description:
We have web application & a centralized database where users can create orders globally. When orders are created time is saved in UTC format in the centralized global database.
somehow along with the UTC order time, timezone description is also being stored in one of the Database table as
UTC time as: '28-NOV-2010 11:24:54 PM'
Timezone description:
(GMT) Casablanca, Monrovia
(GMT) Greenwich Mean Time : Dublin, Edinburgh, Lisbon, London
(GMT+01:00) Amsterdam, Berlin, Bern, Rome, Stockholm, Vienna
(GMT+01:00) Belgrade, Bratislava, Budapest, Ljubljana, Prague
(GMT+01:00) Brussels, Copenhagen, Madrid, Paris
(GMT+01:00) Sarajevo, Skopje, Warsaw, Zagreb
(GMT+01:00) West Central Africa
(GMT+02:00) Athens, Beirut, Istanbul, Minsk
(GMT+02:00) Bucharest
(GMT+02:00) Cairo
(GMT+02:00) Harare, Pretoria
(GMT+02:00) Helsinki, Kyiv, Riga, Sofia, Tallin
.....

With this information how can I map timezone description to V_$TIMEZONE_NAMES. I read Oracle automatically converts to local timezones by considering day light saving timings when TZNAME is given as input with the datetime. by using above timezone descriptions how can I get TZNAMES which are in V_$TIMEZONE_NAMES.
oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - 64bit Production PL/SQL Release 11.1.0.6.0 - Production "CORE 11.1.0.6.0 Production"
I am trying to write a function that accepts LOCAL DATE, LOCAL TIME, LOCAL TIME ZONE, COUNTRY CODE as inputs, and UTC DATE, UTC TIME as outputs. LOCAL DATE, LOCAL TIME, LOCAL TIME ZONE has to be of DATETIME datatype, and COUNTRY_CODE of VARCHAR2(3).
The data's are store in UTC time for all the country. we have to convert this to local country time. I build the procedure will generate the statement as per the country. But some of the timezone is working. like first example is working,second example is not working. I am getting following error.
dbtimezone is UTC-4
ORA-01882: timezone region not found
ex1: update Test.Maindata set MODIFIEDDATE=FROM_TZ(CAST(MODIFIEDDATE AS TIMESTAMP),'GMT') AT TIME ZONE 'America/New_York';
ex2:update Test.Maindata set MODIFIEDDATE=FROM_TZ(CAST(MODIFIEDDATE AS TIMESTAMP),'GMT') AT TIME ZONE 'Asia/Amman';
I have a UI which is java and database in oracle 10g and database resides in India. Now the user use this application across the world. Date related value stores in IST format.
Now the requirement is whenever any user open the application in USA ,then date value should convert into their local time zone. So is there any way in oracle to convert and show the date value according to their local time zone.
SNRCTL> stat LISTENER Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER))) STATUS of the LISTENER ------------------------ Alias LISTENER Version TNSLSNR for IBM/AIX RISC System/6000: Version 11.2.0.1.0 - Production Start Date 19-JAN-2013 00:50:10 Uptime 0 days 0 hr. 29 min. 51 sec Trace Level off Security ON: Local OS Authentication [code]....
In every oracle documentation for e.g:11.2 Scan and Node TNS Listener Setup Examples [ID 1070607.1] we found the local listener status showing both local-ip and vip. Why is not showing in our case?
I need the timezone of the server that the DB sits on. I don't want the offset. I need the region name. This is because some regions use daylight savings time and some do not. Plus an SA can change the time of the OS. Another company manages our servers and DBs in production and we don't have contact with them. We could use a lookup talbe and just populate it, then update it when we find out what it is in production. The problem is that I have seen cases where the timezone on servers change. Considering the lack of contact between the teams, we really need a reliable way to get the timezone out of the DB.
We tried several ways. My list is below and I explain why this is not working.
examples:
sessiontimezone: this is the timezone of my server. In theory it should be the same as the DB. We cannot take the risk that this will be out of sync. dbtimezone: This gives the offset. Such as -5:00 for US EST. There are multiple regions that have this. Some do not use daylight savings time and some do. We would need America/New York instead.
sessiontimezone gives the timezone setting for the client. This can be altered. dbtimezone just gives the offset such as -5:00
We get data feeds from different parts of the world. We get some data based data that is local to that regions timezone. We need to partition on this field. So we need to add a field to the DB and normalize it to the time local to our DB Server. So if we get a record from california and the DB is on a server in US EAST, we add 3 hours. The offset won't work...
1. a timezone that we are getting from may not be in daylight savings time. We are partitioning by hour.
2. We would hit daylight savings time in New York before we hit it in California, so we would need to account for that in the math.
This hourly partition is a fixed and hard requirement. We need this to be absolutely accurate.
Here is what we tried:
What I want (pseudo-code): “Select XXX as timezone_region_name” to return “America/New_York” or “UTC”. It may be that the timezone was not set for the database at install time, and if it were, these queuries would work.
-- FAILED SELECT DBTIMEZONE FROM dual;

I have an interesting problem. I have a server in the UK and I have three databases globally - UK (FINUKQ1), NY (FINNYQ1) and TK (FINTKQ1). The NY and TK databases will be migrated to the UK server as part of a consolidation project. Obviously, Time Zones and DST are the biggest concern for me.Here was my plan for the implementation (concentrating on Time Zone/DST issues).
Added to .profile: -------------------- if [[ "$ORACLE_SID" = "FINTKQ1" ]]; then export TZ="Asia/Tokyo" elif [[ "$ORACLE_SID" = "FINNYQ1" ]]; then export TZ="America/New_York" else unset TZ fi echo "TZ=$TZ"
Once environment has been set start database and listener.
Change database TZ: ----------------- alter database set time_zone='Asia/Tokyo'; alter database set time_zone='America/New_York';
Check database TZ: select dbtimezone from dual;
Add trigger: ------------ CREATE OR replace TRIGGER sys.timezone_check AFTER startup ON DATABASE DECLARE
[code]...
The trigger was there to put the database in restricted session if it is started in the wrong TZ and an error written to the alert log. The check was done on the dbtimezone and the dbname. Quite simple. Only issue is that it doesn't work as I wanted as dbtimezone and TZ are separate and disparate entities. i.e. I can start the TK database up in UK time (which will be incorrect for this project), and check the dbtimezone and it will show as 'Asia/Tokyo'.
Is there a better way of checking? Any trigger like this to compare TZs etc?
I have one issue My server is in france and it is in french timezone but when I query for sysdate it returns US time.
In '/etc/sysconfig/clock/' Zone= europe/paris UTC= true
echo $TZ variable is returning nothing.
sysdate = us time systimestamp= us time current_timestamp = french time current_date = french time dbtimezone= europe/warsove, sessiontimezone=+2.00( which is also europe timezone offset) tz_offset(dbtimezone)=+2.00, tz_offset(sessiontimezone)= +2.00 i.e europe os timezone= europe/paris.
This command "./emctl config agent getTZ" is also returning timezone as europe/paris
Also in "emd.properties" file "agentTZRegion" parameter is set to europe/paris
Oracle version= 11.2.0
Now I don't understand why this sysdate and systimestamp is returning "US time zone" while everything else is returning french time zone.
I'm in the process of testing a restore/recover from a simulated full system and media loss. A level 0 backup was taken from the server, and I'm trying to restore/recover to a point in time on a second server. I have created the database (with the same name) and have been able to successfully restore both the controlfile and spfile from the autobackup.
how does RMAN treat the "set until time"? The level 0 was taken on a database/server that is in CST while the database I'm trying to do a restore/ recover to is in EST. So when trying to do a point in time recovery, should I specify the time in EST or CST?
I'm going to migrate my current db 9.2.0.8 (Timezone version is 1!) to a new server 11.2.0.3, so I was wondering if I must upgrade timezone version of my current 9iR2 to version 4! Before upgrade it...Btw my new server has timezone v14.
I have a requirement in which a particular a timestamp column (date1) whose values are in CET timezone needs to be converted to EST and day light savings should be taken care of in the conversion logic. I should not use any ddl statements for altering the timezone and all.
EMPLOYEEIDNUMBER(12,0) PUNCHDTM DATE TIMEZONEIDNUMBER(12,0)
I want to return any results where any employee id that has 2 different timezoneid's on the same date. I would actually like, if its possible, to select these entries to display on one row per employee per day. So for example
I am having an issue to connect my C++ application to my Oracle DB. When my code calls
oracle::occi::Environment::createEnvironment(),
I get an error "ORA-01804: failure to initialize timezone information".
The application works on other people's Windows machine with their Oracle DB. But it doesn't work from my machine connecting to their Oracle instance. So I guess the issue does not come from my instance but rather from my Oracle dlls maybe?
if it is possible to save an email send from an ORACLE pl-sql packages in the Oracle database it self? The email is in my case created and send directly using the oracle utl_smtp-package.
I have no problems with attaching doc's and so on in this mail. But i simply cannot find a way to save, the email i'm sending in the Oracle-database. The purpose of saving the email in the DB is that i want to be able to reopen an send email, to se exactly what was send.
I have created one master detail form where on master i have one field with name status and if the status is changed to A it will prompt me to another detail block where i will fill the details and in case after i entered the details and then i decide it not to save and come back to main form without saving...how i can do it . I used go_blok In detail to go to master it goes to master but when i am saving the master the details get saved along with it.I dont want to save the detail and go to master block.
i have developed a form in 9i. can i view the fmx file on web. or tell me the extenstion what name of form should i use to save the form to view on the web.
My query is: I have created a master-child forms on one canvas. In a child form i have to enter multiple records, but after entering every record its prompting me to save it. I want to avoid it and save the entire thing once all my records are entered.
When creating objects, is there a way telling Oracle not to store(overwrite) procedures or other DDL in the database until the statements have no compilation errors?
