Defining two points in time daily ...a job to be executed...

Hi,
I use Oracle EM 10g Standard Edition and using the Dbms Scheduler... i want to define two points in time (for example 12:00 pm and 6:00 pm) in order a job to be executed daily.... Is this possible....????
So far , i have defined just once(let's say 6:00pm)...
Thanks a lot,
Sim

As it seems that my requirement cannot be done... i have considered to create another schedule and a respective job - running at this schedule....at 12:00 for example , whereas the first one runs at 18:00.....
Greetings,
Simon

Exact Steps to schedule a background job a specific time daily :

Dear All,
Please let me know the whole process involved in schedule a background job a specific time daily. what is calender id. I could not understand what it has given in SM36.
Thanks in advance.
Rgds

Hi prem
this is complte procedure for ur requirment.
Scheduling Background Jobs
Use
You can define and schedule background jobs in two ways from the Job Overview:
Directly from Transaction SM36. This is best for users already familiar with background job scheduling.
The Job Scheduling Wizard. This is best for users unfamiliar with SAP background job scheduling. To use the Job Wizard, start from Transaction SM36, and either select Goto ® Wizard version or simply use the Job Wizard button.
Procedure
Call Transaction SM36 or choose CCMS ® Jobs ® Definition .
Assign a job name. Decide on a name for the job you are defining and enter it in the Job Name field.
Set the jobu2019s priority, or "Job Class":
High priority: Class A
Medium priority: Class B
Low priority: Class C
In the Target server field, indicate whether to use system load balancing.
For the system to use system load balancing to automatically select the most efficient application server to use at the moment, leave this field empty.
To use a particular application server to run the job, enter a specific target server.
If spool requests generated by this job are to be sent to someone as email, specify the email address. Choose the Spool list recipient button.
Define when the job is to start by choosing Start Condition and completing the appropriate selections. If the job is to repeat, or be periodic, check the box at the bottom of this screen.
Define the jobu2019s steps by choosing Step, then specify the ABAP program, external command, or external program to be used for each step.
Save the fully defined job to submit it to the background processing system.
When you need to modify, reschedule, or otherwise manipulate a job after you've scheduled it the first time, you'll manage jobs from the Job Overview.
pls give points if it is usefull

What time will a job run using only REPEAT_INTERVAL of FREQ=DAILY

What time will a job run using only a Schedule REPEAT_INTERVAL of FREQ=DAILY?

Hi,
There are two cases
- if you set a start time it will run at the hour and minute of the specified start date
- if start_date is left as NULL then it will run as soon as it is enabled (or at create time if enabled is true) and thereafter at the hour and minute when it was enabled.
Basically it makes the best attempt to run at the same time every day which is either the start_date or the enable time.
Hope this helps,
Ravi.

10.7.2 Lion freezing / apps lock up, must hard reset 2-3 times daily

I've seen several posts on this -- oddly, some of them are archived even though there has been no resolution...
Would love to hear people's experiences and especially if you have a fix. Would REALLY love it if Apple would get off their duff and give us a working O/S.
Ever since upgrading to Leopard I've been having problems with system stability and, specifically, with lockups. Usually this starts out with a few applications get "hung" (beach ball). Again, usually, I can force quit them, restart and continue for at least a little while... but, it always marks the beginning of a downward spiral. The final straw seems to be when Finder locks up. Once Finder locks, the system becomes unresponsive overall and I can't shut down without doing a hard reset (either cmd-opt-power or, more often, just hold power until a get a hard reboot).
Some of the behaviors I'm seeing:
Apps start to lockup. Best option at this point is to quickly shut everything down and restart. On occasion I get a software restart if I'm prompt about it.
Finder locks up... forget it. Hardware restart is in my future... will generally try to save work, but it seems that anything involving disk / file system access is completely frozen.
About one out of two times, the login screen is very slow to appear (about a 2 minute boot), and then it fails to respond to my wireless keyboard &/or mouse. Sometimes the mouse works, keyboard doesn't. If I wait for 1-2 minutes, it will usually "wake up" and suddenly gets all of the input in one blast... but usually I lose patience, open up the laptop, do another hard reset.
Sometimes the screen saver won't release control of the machine (much like login screen). I can move the mouse, tap keys, etc., screen saver just keeps right on running blithely along...
On rare occasion, even the force quit panel (cmd-opt-escape) refuses to appear.
Of late, I've taken to launching Terminal on login so that it's available (because after the lockups start, I won't be able to launch it). Then, I can issue a "shutdown -r now" which, most of the time, seems to work pretty well. I hate doing a hard reset, always worried it will lead to a damaged file structure or lost work.
I've tried a number of fixed, including (at the height of it) reinstalling 10.7.2, which I did a few days ago. It made no difference at all... Also tried resetting NVRAM, etc. About the only folklore I haven't tried yet is switching to Chrome or Firefox. A lot of people are blaming Safari for all of this, so perhaps I'll try that next...
I'm suspecting that Time Machine is making the situation worse, but turning it off (and disconnecting the drive) does NOT solve the problem. It seems to go a little longer in-between system lockups. Same symptoms... apps become unresponsive, one after the other starts to beach ball, eventually the whole system locks up... I'm wondering if it has something to do with disk access, as posted in other threads. I've been trying to minimize disk access wherever possible, for one, just plugging in my Time Machine drive about once a day, let it backup, then unplug. Not really sure if it's helping or not though.
Currently, I'm running into this on average 3 times daily (worst day was 6 times, best day was just once, yay...) Yes I've been keeping track. By my count I'm also losing up to two hours a day, because the shutdown / reboot process is so baby-sitting intensive (and I have to do it several times a day).
Very, very frustrating. This is definitely the worst O/S release Apple has ever put out there. I'd like to go back to Leopard, but worried about the downgrade... arrrgggh. (Wish Mr. Jobs was still around, somehow I think he would never have tolerated this...)

Magic Mouse's connection drops about every 15 to 40 minutes of typing, often in this Discussion. Apple Care suggested that keeping my battery charge above 50% would solve it. It didn’t.(My batteries are Apple’s, as is the charger.);

Time Machine three times over the last 1 1/2 years (OS 10.5 once and Lion twice) has complained that its HD is full when it is only ~1/2 full. A full reset on the last two did not cure it (I had not discovered Pondini's Full Reset until Lion). Pondini's symptom's and solutions did not match the error. Each time I had to erase and start again;
A couple of months ago, as a test, (after confirming my daily bootable backup of my system done by Carbon CopyCloner), I re-installed Lion from the InstallED.dmg, accepted the invitation to restore from TM, and upgraded to 7.2. All looked well except Mail displayed only the Header and first two lines of the body of messages, all the rest of the bodies were blank. Another major thing did not work after this re-installation (I can't remember the details now);
Carbon Copy Cloner can fail to find its Firewire backup HD about every 10th time (I have a daily schedule). The connections to the drive are plugged in OK but the drive is no longer mounted, whether the iMac has been restarted or woken up. CCC has been absolutely rock solid for years until Lion;
My Canon scanner (current driver, and it always worked before Lion), more times than not complains that it cannot start because it is in use elsewhere. I have to unplug its USB and re-connect.
In SystemPrefs > iCloud, a dialogue box said that Sys. Prefs. wants to use confidential info in my keychain. I press “Deny” and the box returns for ever until I force quit Sys. Prefs.
Software Update repeatedly tells me that a certain update is available but I already have installed it.
For those silly enough to install a new OS within a year of its introduction (not me: my iMac came with the wretched thing in it), some bugs can be expected, but not this many (at least in my opinion). All previous updates going back to 1997 have gone much more smoothly than Lion on my machines.
Although I am in a minority (given the huge number of sales of Lion – although MacWorld reports that sales of Lion are faltering), I am sorry to say that I have fallen out of love with Apple. I would gladly trade the elegance and the fancy features for a bit of “Works out of the box”, “It just works”, “Computing for the rest of us”.

Query Question - Linking in Time Span Data to Point-in-Time References

I am trying to pull historical data from a time-span table of records, using another point-in-time reference. I have been unsuccessful.
I've thrown some sample tables and data together to illustrate what I am seeking:
Create Table EmployeeInfo (
       id Number(10,0),               -- Employee ID Number
       Name VarChar2(32 Byte),        -- Employee Name
       CurrentShift VarChar2(2 Byte) -- Current Employee Shift
Create Table ShiftChanges (
       id Number(10,0),               -- Employee ID that this shift change record is for
       ChangeDate Date,               -- Date that this Change Took Place
       OldShift VarChar2(2 Byte),
       NewShift VarChar2(2 Byte)
Create Table TimeCard(
       id Number(10,0),               -- Employee ID Number for this Timecard
       WorkDay Date,                  -- What Day is this Timecard for?
       Hours Float(63)                -- Number of Hours worked.
COMMIT;
INSERT INTO EmployeeInfo VALUES (100,'John Doe','Days')
INSERT INTO EmployeeInfo VALUES (101,'Jane Doe','Days');
INSERT INTO TimeCard VALUES (100, to_date('01012010','ddmmyyyy'), 10.5);
INSERT INTO TimeCard VALUES (101, to_date('01012010','ddmmyyyy'), 10);
INSERT INTO TimeCard VALUES (100, to_date('02012010','ddmmyyyy'), 9);
INSERT INTO TimeCard VALUES (101, to_date('02012010','ddmmyyyy'), 10.5);
INSERT INTO TimeCard VALUES (100, to_date('03012010','ddmmyyyy'), 8);
INSERT INTO TimeCard VALUES (101, to_date('03012010','ddmmyyyy'), 7);
INSERT INTO ShiftChanges VALUES (100, to_date('02012010','ddmmyyyy'), 'Nights', 'Days');
COMMIT;I could do a query such as:
SELECT TC.id,
       EM.Name,
       TC.Workday,
       EM.CurrentShift AS Shift
FROM   TimeCard TC,
       EmployeeInfo EM
WHERE (TC.ID=EM.ID(+));But it will not give me the historical shift, only the current. Since John Doe changed shifts on Jan 2 from Nights to Days, the above query would not reflect it.
I have attempted to join the historical table using a less-than operator. This doesn't work since more than one row can be returned.
SELECT TC.id,
       EM.Name,
       TC.Workday,
       SC.NewShift AS Shift
FROM   TimeCard TC,
       EmployeeInfo EM,
       ShiftChanges SC
WHERE (TC.ID=EM.ID(+)) AND
       (TC.ID=SC.ID(+) AND TC.WORKDAY<=SC.WORKDAY(+));The problem stems from the fact that you need to examine multiple records in one table in order to obtain the correct historical data for the other.
The following SQL script {color:green}does work{color} - if the values are defined ahead of time.
DEFINE EMPID=101;
DEFINE CHGDATE=to_date('01/01/2010','dd/mm/yyyy');
SELECT SQ.Shift
FROM   (SELECT ShiftChanges.NewShift AS Shift,
                RANK() OVER (ORDER BY ShiftChanges.ChangeDate DESC) R
        FROM    ShiftChanges
        WHERE   ShiftChanges.id = &EMPID AND
                ShiftChanges.ChangeDate <= &CHGDATE
        ) SQ
WHERE R = 1However, I have been unsuccessful in adapting it to the example tables I provided. If I insert the query as an inline subquery* in the select statement, it won't work, since the criteria is nested two levels down, and I can only get parent values within the first level.
I haven't thought of a way I can do this using a nested subquery - I keep running into that problem - how do you link in Time-Span data with a point-in-time reference.
Any ideas / enlightening thoughts?
Thank You

I changed the tables to hold VARCHAR2(6) shift information and your query to reference the ChangeDate column.
I also assume you meant to link a TimeCard entry with the most previous ShiftChange entry rather than one that occurs after the time worked (TC.WORKDAY>=SC.CHANGEDATE(+) rather than TC.WORKDAY<=SC.CHANGEDATE(+)):
Another issue you don't take into account the case where there has been no shift change. In that event you need the current shift from the EmployeeInfo table which is taken care of with the NVL function.
You correctly note that multiple shift change records will result in duplicate TimeCard records though your test data fails to check for that condition. I added this row:
SQL> INSERT INTO ShiftChanges VALUES (100, to_date('03012010','ddmmyyyy'), 'Days', 'Nights'); Now it is apparent
SQL> SELECT TC.id,
2         EM.Name,
3         TC.Workday,
4         NVL(SC.NewShift,EM.CurrentShift) AS Shift
5 FROM   TimeCard TC,
6         EmployeeInfo EM,
7         ShiftChanges SC

        ID NAME                             WORKDAY   SHIFT
       100 John Doe                         01-JAN-10 Days
       100 John Doe                         02-JAN-10 Days

       101 Jane Doe                         01-JAN-10 Days
       101 Jane Doe                         02-JAN-10 Days

7 rows selected.The reason for the duplicate Jan3 time is the two shift change records. We are matching both ShiftChange records that occured before the 3rd.
We also see that your test data has John starting out on Days and then shifting from Nights to Days on the 2nd for no real change. Fixing that:
SQL> DELETE from ShiftChanges where ID = 100;
2 rows deleted.
SQL> INSERT INTO ShiftChanges VALUES (100, to_date('02012010','ddmmyyyy'), 'Days', 'Nights');
1 row created.

Floating point to time conversion

Hi all,
I need to convert floating point value to time.Any help would be gr8

Hai,
Define two variables,one as float & another one as time take a & b.After assigning values to a,assign a to b.Then write b.The float value will be converted into time format.

Define access point to connect?

A couple of applications on my phone, particularly Ovi Maps keep doing this and it's getting REALLY annoying.
Start using the application, it comes up with the following:
"Network connection required.Define access point to connect?
Then it'll give me a selection from a list of my networks various protocols.
It will regularly ask me again and again while the app is running, often coming up in front of other applications i am using at the time!
How can I stop this?
I don't want to have to define anything for specific applications. I want my phone to connect in one of two ways without my input:
1. If I am within range of a Wifi connection it knows, connect via that.
2. If not, connect via 'O2 Active'
Is there a way I can set this so my phone just does the above and never asks again?

It is the Assisted GPS positioning method access found in Menu > Settings > Application Settings > Positioning > Positioning server use which keeps asking for a Network access point not OVI Maps application itself which may be set "Offline" or "Online".
If you have not set "Save location info" = No - in Camera > Options > Settings - you may get the same response.

Switch redo logs hourly to provide point-in-time?

Hi All,
Oracle 11G on Windows 2008 R2
I am learning the details of managing backups/restores and want to be able to provide a good point-in-time capability in case of a disaster. Is it good practice to schedule an hourly job that does ALTER SYSTEM SWITCH LOGFILE; ? Does this cause the redo log to be archived every hour so if I needed to restore, I know that I can at least restore to the previous hour (using the archive logs) and before?
Thanks in advance

Aman beat me to what I was going to say. I'll just add a couple of points:
This really needs to established in concert with management, normally called an SLA (Service Level Agreement). In a nutshell, you define what kinds of failures you allow for, how quickly recoveries or other procedures such as failovers will happen, what uptime is required, and so forth. Of course, in reality many places won't spend the dollars to properly evaluate these things unless they are about to spend millions on an upgrade, so for ordinary places with ordinary business software the 15-30 minute rule covers many common recovery situations as a first approximation. Simply asking management often gets a wrong or inadequate answer.
Personally, I find there are times of large loads or updates, so I size redo to handle those by testing, then use the lag target to have a reasonable time switch during normal operations. This winds up requiring large redo, but archived redo is much smaller, except of course during the heavy times. The same with undo also; yearly operations or massive updates require large undo, so just keep it around rather than trying to size it under the gun when it fails the next year. Redo is a critical resource, and may benefit from special filesystem handling, depending on your storage hardware.
Job number one for a DBA is to not lose data, so recovery skills are critical, to the point of sometimes having to push management to do things right when they don't understand the value of their data.

Internet connection failing dozens of times daily for weeks now

My computer's connection to the Airport Express base station has no problems at all. But the internet connection goes out literally dozens of times a day (at no predictable schedule); this has been happening for almost a month. I originally thought the problem was with the internet provider, but I'm now beginning to think that either my settings are wrong, or that I have a corrupt file somewhere. Here are the details:
I connect via a cable modem (Time Warner - Road Runner). I know people have had problems with Time Warner, so I assumed that was the issue; however I've had 3 service calls and they've checked signal strength inside and out, and swapped out the modem and the cables. I don't think it is simply problems in our geographic area (i.e. greater Los Angeles) due to the fact that the Internet fails sometimes 40-50 times daily, and the problem began when I upgraded from an old Airport base station to a brand new Airport Express about a month ago.
The airport/internet connection is shared 3 ways: two MacBook Pro computers and one iPhone. My Airport's internet settings are as follows:
Configure IPv4 using DHCP.
DNS Servers: 66.75.160.63 and 66.75.160.64 (note I have already tried swapping these for OpenDNS -- this did NOT solve the problem)
Domain name: socal.rr.com
DHCP Client ID: [blank]
Ethernet WAN port: Default-Automatic
Connection Sharing: Share a Public IP address
DHCP Beginning Address: 10.0.1.2
Ending Address: 10.0.1.200
DHCP Lease: 4 hours
NAT settings are all unchecked
One of the main reasons I believe that the problem is with my computer's settings or a corrupt file is that I can fix the problem whenever the Internet "goes down" almost 100% of the time by doing the following: after loading Airport Utility, I make ANY trivial change (i.e. changing the DHCP lease from 4 hours to 5 hours) and then click UPDATE to refresh the Airport base station. This fixes the problem almost 100% of the time. But then, anywhere from 10 minutes to 3 hours later, the Internet connection goes down again. [Unplugging the power from the modem, waiting 30 seconds, and plugging it back in ALSO fixes the problem almost 100% of the time, until it goes out again a little while later.]
I can't think of what else to try -- but any advice would be greatly appreciated -- it's impossible for us to work with the Internet constantly going out throughout the day, every day.
Thank you!

I had a similar issue with a local fiber provider in Loma Linda, CA. Internet connection with a new Airport Extreme was fast but with drops at regular intervals every day. Resetting the airport fixed the problem but there was one difference, even a direct connection through ethernet cord to the gateway also failed at regular intervals.
After trying everything, the problem was fixed by asking the fiber service provider to switch the port the wire from my home was connected to at a central box somewhere in my neighborhood.
Good Luck!

Balance Sheet translation at spot rate at ANY point in time

My client produces its financial accounts in AUD. They will have open items in AR, AP and Bank in foreign currencies. WITHOUT running periodic valuation they wish to produce a Balance Sheet at any point in time during the month applying the applicable daily spot rate to valuate the Foreign Currency open items (for reporting purposes only). I have run S_ALR_87012284 and maintained the special evaluations tab for Display Currency (AUD), Key date for translation (current date) and exchange rate type (spot rate type). However, this does not appear to be revaluating the open items in the subledger accounts to produce the balance sheet at the current spot rate. Appreciate input / alternate approach. Cheers, Dean.

Hi Chirag
As per Oracle following are the rules that has to be followed for translation.
1. For Balance Sheet Accounts (Asset & Liabilities) GL as a default uses the YTD rule.
2. For P&L Accounts you can choose between YTD and PTD rule. So in your case you can use the default PTD Rule. (Profile Option 'GL Translation: Revenue/Expense Translation Rule')
YTD Rule = (Translated Period Amount = Period-End Rate x YTD Ledger Currency Balance - Beginning Translated Balance).
PTD Rule = (Translated Period Amount = Period Average Rate x PTD Ledger Currency Balance)
Hope this helps.
Regards,
Gautam

After uploading our phones with the latest update, we have noticed that the battery life has deminished considerably. I now have to charge my phone overnight and two or three times a day. Prior to the update, my battery life lasted me at least a full day

After uploading our phones with the latest update, we have noticed that the battery life has deminished considerably. I now have to charge my phone overnight and two or three times a day. Prior to the update, my battery life lasted me at least a full day. We have several phones in our office and the ones that have updated (4) now have issue holding a charge/battery life. I really liked this phone and can not believe that you are now going to charge us $79 a battery to fix what is most definately a problem with your latest update. I know other people outside of our company that are having the same problem. Not to mention when I called AT&T it was confirmed to me that they are hearing the same issue and then some from other customers as well. Your own people, once I talked to them earlier today, told me they are showing a history of issues that are showing up after the update was put in place. Of course she tried to say, "Maybe the age of the battery and the update both contributed". Whatever.
I want you all to know how disappointed I am in your company for the handling of this issue. I always thought "Apple" was the line I didn't have to worry about having any types of issue. And that you all would stand behined your product 100%. Now I am not so sure.
I would love to hear back from your company on how you perceive the issue with all of these phones that prior to the update didn't have any issues and how after the update THEY ARE NOW having issues. I do not believe this was an issue due to the age of a battery and that was pretty lame to say so. It was fine and now its not.
Please feel free to contact me and help me figure out a way to pay for all of the batteries that will be needed for our company to contiue doing business as needed.
Thank you.

Structuring a Business Area for Reporting Periods and Points in Time

Dear all,
I'm in the process of designing my first business area for discoverer.
The database is for people staying in accommodation over various periods.
(Anything from individual days to periods of 15 years!!)
The reports I'm producing fall into two categories:
(a) Reports on periods of time such as:
Accomodation days during a year broken down by Region
Trend of accommodation days per month during a two year period
(b) Reports on a particular point in time such as:
Number of people in accommodation on a particular day
I'm trying to work out how to structure the business area.
If I think about requirement (a), I'm inclined to create a view which
splits up periods into one month chunks (the smallest period I think I need).
By this I mean having a view which gives me a row for every month for which any period of accommodation is active. This makes reporting on a monthly basis fairly easy.
If I think about (b), I'm inclined to create a view which leaves the accommodation periods as single rows and then calculate a boolean field which indicates whether that accomodation is active on the date in question.
It seems that these two requirements need different structures in the business area. Maybe it's best to create two folders which draw on the two different views.
Any thought would be appreciated.

Suhada

Hi,
As you would probably expect, it all depends on your requirement and the table design.
You can create a date hierarchy in Discoverer that contains the day, month, year levels and this will make it easy to create reports with totals aggregated at these levels.
However, if your table contains, for example, the start and end dates when people move in and out of accommodation, then you will need to have a period table so that you can report on the months between the start and end dates. The period table will list all past and future months and you can join this to your data to obtain totals for all the periods.
If you need to have reports that display zeros or nulls for periods where there is no data, then you will need to outer join your data with a period table.
The decision on whether to use views or folders and joins in the EUL depends on the complexity of your data model. If you need to join many tables together to produce a single report, then you should consider putting some or all the joins into database views.
Hope that helps,
Rod West

Materialized View - Point in time refresh

I have a MV group which refreshes from a bunch of master tables. The master tables are constantly getting updated from an OLTP application. In this scenario, I want all the MVs to hold data which was available at the time the refresh started and not the changes after that.
Eg:
Master tables are T1, T2 ... T20 refresh to MVs T1_MV, T2_MV ...T20_MV
All the MVs T1_MV to T20_MV are in a refresh group.
At 3 PM: Execute an explicit refresh for the MV refresh group
At 3:05 PM: OLTP application inserts a record into table T5 & commits
At 3:06 PM (rather any time after 3:05 PM): Refresh of T5_MV happens. Will the latest insert get captured in T5_MV? I actually don't want this to happen for my requirement, because I want the data captured as of 3 PM into the MVs.
The Oracle Advanced Replication guide says the following about Materialized Views -
+"A materialized view is a replica of a target master from a single point in time."+
From the above line, it looks like by default this will not be captured in the MV. Can someone please confirm my understanding ?

MVs in a Refresh Group when refreshed as a Refresh Group are refreshed as of the same point in time.
So if the Refresh Group begins at 3:00pm and ends at 3:25pm, all the MVs in that group reflect the data as in the source tables as of 3:00pm, ignoring any updates to source tables after 3:00pm (i.e. while the Group is being refreshed).
However, if you refresh MVs individually, then each MV is refreshed at it's relative point in time -- so individual Refreshs of MVs would not be to the same point in time.
How have you defined the Refresh Group ?
How do you execute the Refresh for the whole Group ? What PLSQL procedure do you use ? What parameters do you use ?
Ensure that you do not execute an individual MV Refresh.

Update clone db to a point-in-time

Hi guys,
I am planning to implement a point in time recovery. I have a production database that I have successfully cloned by using hot backup and applying the necessary archived redo logs. I need to do this automatically daily. How can I do this? My purpose is to have a clone db that is one day delayed compared to the production database. Can I use the RECOVER DATABASE UNTIL TIME date? Is there a better/another way?
Thanks

Hi,
You can use dbms_wm.SetValidTimeFilterON to specify the point in time that you are interested in.
SQL> exec dbms_wm.SetValidTimeFilterON(to_date('05-01-2005', 'MM-DD-YYYY')) ;
This date needs to be contained within your session's validtime range.
Regards,
Ben
