Question { 11033 }

On a day, I load 10 rows in my target and on next day if I
get 10 more rows to be added to my target out of which 5 are
updated rows how can I send them to target? How can I insert
and update the record?


Answer

Hi Guys,

For the above req. we can't use SCD 1 or 2 or 3.
Bcoz for scd1 it inserts the new record and updates the
updated record.And here we wont be having any updated
records only new records will be there.

So according to me,the best option for the above scenario
is go with Incremental aggregation.

Please let me know if you have suggestions regarding this.

Thanks,
James.

Question { 10413 }

major difference between normal loading and bulk loading?


Answer

The major difference is while going with normal load,we can
have session recovery whereas in Bulk loading we can't.
Some of the other differences are as follows:
Normal Bulk
1.Enters session log before 1.Doesn't enter the session
loading into target there by log and loads directly in
increasing the loading time. target there by decreasing
the loading time.
2.Less performance. 2.High performance.
3.Indexing possible. 3.No concept of indexing.
4For small amount of data. 4.For huge amount of data.

Please let me know if you have any further differences.
Thanks.

Question { EDS, 15734 }

1,If there are 3 workflows are running and if 1st workflow
fails then how could we start 2nd workflow or if 2nd
workflow fails how could we start 3rd workflow?


Answer

When 3 workflows are running sequentially,we can definitely
give the dependancy condition by using LINK condition
between the first two workflows as "Failed".
i.e. the second workflow gets started only when first
workflow is failed and same can be applied between second
and third workflows.
Guys any suggestions please let me know.

Thanks,
James.

Question { TCS, 7984 }

3,if our source containing 1 terabyte data so while loading
data into target what are the thing we keep in mind?


Answer

I agree with you Chinni.
But my suggestion is instead of loading huge amount of data
at a time,we can always split the source if it is a file
using unix and extract the data from all the source files
using indirect type and load into target.

Please let me know if you have any suggestions.

Thanks.
