Does ODI keeps the record of last run date of interface?

Target:Oracle
Source:MS SQL
ODI:11g
My requirement is I have a source table, Whatever operations performed on that (like insert,update etc) table, I want to load those records into the target table. For that I have created an Interface which runs daily at 6 PM.While loading, I have put one filter which loads only those data which got inserted/updated on current date(GETDATE()).Suppose the case, If my ODI has been down(because of any reason) since 3 days. In this case I have no option to load the records who got changed in that three days. On the fourth day I start the ODI then, how can I get data which got changed in last three days.
Is there any place where ODI keeps the record of last run date or something of interface ?
If I use CDC in that case, once the ODI down then the journalism can not able to keep the changed data info.
How can I load the changed data into the target.?
Thanks,
Shrinivas

If you have a date column in source and target , I guess you might be having a you are using date , you can use a filter and write the expression like this
Source_date > (select max(date_created/update) from schema.target_table)
I have validated this expression and it validated by ODI , I did not try running it , please give it a shot

The hard drive on my laptop died, so i have lost all my music. It is saved on my iphone, is there any way to transfer it across onto my new laptop? Or does itunes keep a record of my purchases?

You should be able to:
Backup the device to the new installation
Transfer your purchases into a newly authorized library
Recover any other media using third party tools as suggested in this post from forum regular Zevoneer
Restore the device from the backup
This process should switch the association of the device to the new library, preserving the data and settings in your apps.
May also be prudent to attempt a backup to iCloud directly from the device before you start... Settings > iCloud > Storage & Backup > iCloud Backup > On. It won't save any media but it would preserve the general account settings and documents in case anything goes wrong while you are trying to extract your other data.
When you get it all fixed, make a backup!

How to get the last run date.

We intend to develop an incremental data load mapping using this strategy:
1) The mapping reads the date it was last run from an auxiliary table.
2) It selects from the source only those rows that were inserted or updated after said date.
3) Then, a post-mapping process updates the last run date in the auxiliary table, using SYSDATE.
The problem with this logic is that there is a gap: if the mapping starts running at 1:00 and ends at 2:00, the rows that are inserted in between will never be loaded.
Is there any way to get the value when the mapping started running? Is there a better way to do this?
Any help would be appreciated.

There is always the possibility of some record updates slipping through the crack if you are depending on dates unless you are very carefull. All of the audit tasks that the OWB-generate code performes take time. Any pre- or post- process that needs to run takes time. So which date is the best cuttoff point to equate to "when the last run of the merge (or insert or update) statement completed"?
Plus, how do you handle reloads if the previous load failed and your mapping had incremental commits?
Is your source on another server? If so, are the dates in perfect synch? The audit tables populate with sysdate of your runtime schema. Is that the same as the sysdate on your source remote database?
I would qualify my query to look for all updates since the start of the last run that finished successfully - adjusted if neccesary for sysdate differences if it is on a remote schema. And make sure that your code handles any reloads gracefully in the event that this brings back data that you have already loaded once. .
Because we use Oracle Streams to load a local staging area, we also have custom code to dump the primary keys of all data changes to utility staging tables while streams is updating the local copy. So, our Person table has an st_Person_delta table that just holds the primary keys that have been updated by Streams since the last ETL run.
During datamart load we disable the streams apply to stabilize our environment, and join these lists of pk's to their source tables to drive our ETL. So we only select data where Streams has performed an update to the row since our last run. When we are done our ETL, we truncate the primary key staging tables, and then turn streams back on to start loading up our new delta into our staging tables again..
The ETL gets pretty complex though when many tables join together in one mapping and you need to check all possible source table deltas to see if any of them got updated to determine the delta for a given dimension or fact record, but it works great once you get it all done.

Keep the record in the view object if deletion failed.

I have a view object which is based on the entity object, when I am trying to delete a row it failed because it has a child record associate with. I know the row is not delete from the database, but the record is deleted fromt the view.
How to keep the record in the View object if delete failed?

Hi,
the row is not delete from the database,refresh the view . re-execute query and the view show the row

Hi, I have quick question about use of USEBEAN tag in SP2. When I specify a scope of SESSION for the java bean, it does not keep the values that I set for variable in the bean persistent.Thanks,Sonny

Make sure that your bean is implementing the serializable interface and that
you are accessing the bean from the session with the same name.

Does ODI has the ability to organize 1000+ pl/sql programs?

Hi experts,
we are proposing ODI to a customer who has 1000+ pl/sql programs to load data to Oracle DW. Besides, there are many complicated dependencies among these programs.
I know that ODI has "package" functionality to build up a workflow and schedule programs like mappings and pl/sql etc... But does ODI have the ability to organize 1000+ of them? And does ODI provide a way like scripting to automatically generate this package? I mean something like Teradata's ETL Automation if anybody ever used this.
Any help will be highly appreciated.
Flo

Hi Flo,
I can't see a way to conver the PL/SQL code to ODI "code" (interface, procedures, etc...) directly but, it is possible to customize an object to read the database PL/SQL dependence and generate a package that call those codes in the right sequence.
An other way, that will bring you all Metadata control (column using information thu all database) is use a customized KM to map the pl/sql programs as table and, then use it in a interface.

Help find the Last run date from previous month

Hi all
I am stuck trying to find the Last Run Date from the previous month.
select distinct(date_ran) from TABLE X where date_ran like '%/11-%' order by date_ran desc gives
"03/30/11-06:19
"03/25/11-03:01
"03/24/11-03:00
"03/23/11-03:00
"03/22/11-03:00
"03/21/11-03:00
"03/18/11-03:00
"03/17/11-00:00
"03/16/11-06:31
"02/15/11-07:42
"02/15/11-06:00
"02/14/11-08:19
Here the result I am trying to acheive is 02/15/11-07:42 ;Note the column date_ran is a VARCHAR2(255) and not a TIMESTAMP
I tried
select ADD_MONTHS(to_date(max(date_ran), 'MM/DD/YYYY-HH24:MI'),-1)
from daily_tests_a
where date_ran like '%/11-%'
order by date_ran desc
which returns 2/28/0011 6:19:00 AM and that is not the result I am looking for

Points in time should always be stored in DATE (or maybe TIMESTAMP) columns. If not, you're going to waste resources converting them to DATEs whenever you need them to behave like DATEs, and risk run-time errors because of bad data.
Normally, the "previous" month means the month before the current month. In April, the previous month is March.
By "previous" month, do you mean the 2nd latest month in the table? That is, this data contains data from February and March, 2011; March 2011 is the latest of those months, February 2011 is the next-to-last, and so is that why you want a date from February?
I tried
select ADD_MONTHS(to_date(max(date_ran), 'MM/DD/YYYY-HH24:MI'),-1)

where date_ran like '%/11-%'

WITH   got_real_date   AS

How does one keep the photo description attached to a photo in iphoto when that photo copies to a disc or flash drive

how does one keep the photo description attached to a photo in iphoto when that photo copies to a disc or flash drive?
the metadata transfers ok, it is the description of that photo that does not transfer.

Use the File -> Export command and note the settings to write the metadata to the file on export.

Hi all,
In JDev 10.1.3.1, Where does JDeveloper save the info about last opened jspx / files ?
e.g:
opened pages are : page1.jspx and faces-config.xml
after we save and close JDeveloper and Open again, i will start with same opened page/files : page1.jspx and faces-config.xml.
Where does JDeveloper save this settings ?
Thank you,

Make sure you do a reset, not a restart. Press and hold both buttons, ignore the "slide to turn off" message and let go of the buttons after the Apple logo shows up on the screen.
If you did that and it did not bring any change, try to set it up as new device, as explained in this article:
How to back up your data and set up as a new device
If it does not work the first time, try not to use the backup afterwards in a second attempt, in case it contains corrupt data.

Last run date & time & multiple files handling

Hi frnds,
i am working on an outbound interface in which i am retrieving data from custom db table,processing it with other db tables and writing the final output into a file into the application server and updating the custom db table.
Now i have an issue here when i am giving plant as input in selection screen (select-options), i should also get those plants from my custom table which have no last run date and time.
How to get that?
Next part of my question is for multiple plants entry,multiple files have to created in application server.
Presently, i have concatenated the file path n name.Do i need to loop the same with s_werks.Will it work
Also i used an internal table for update data storage.When multiple plants are their how to handle the updation.
Rgds,
Simran

Hi.
In ur reply i did'nt understood two things
1) this is how i'm doin the selection
    select lt_run_dt
           lt_run_tm
    into table itab1
    from z_table
    where prog_name EQ sy-repid
    AND   plant IN s_werks
will it give me plants whose last_run_date and last_run_time are not in the z table?
2) If you are going with select-option from parameter, then if you have to write a FILE per PLANT. Then you can loop at plant->extract the data-> write to app server-update z table->end loop
Does that means:
loop at s_werks
open dataset
transfer
modify
endloop
Kindly clarify to solve this issue.
Rgds,
Simran
