using informatica for one to one mapping for more than one source with different source structure

0 votes
416 views

How to use a workflow for one to one mapping for more than one source with source name as parameter with different source structure in Informatica power Center. I have a data migration where i need to unload 800 tables into delimited text files. Is there a way we can give the table name in parameter while running the workflow and the data will be unloaded to the output text file. Need help.

In Informatica PowerCenter, you'll need a separate mapping for each structure. Eg. if each one of 800 tables mentioned has unique structure and / or datatypes, you'll need 800 mappings. If the structure is shared across all 800 tables, one mapping can handle it. And if you've got 4 different structures, than 4 mappings will do.

If you do have 800 different structures, than it would be great to automate it. If I understand correctly, it would need to work like this:

but in the reverse direction (Table-to-File, rather than File-to-Table).

I have some files that I would like to consolidate into a single database table. The files have similar but different formats. The files look something like this:

FileOne:
•ColA : string
•ColB : string
•ColC : string

FileTwo:
•ColAA : string
•ColBB : string
•ColCC : string

FileThree:
•Col01 : string
•Col02 : string
•Col03 : string

The destination table looks like this:

TableDestination:
•ColFirst : string
•ColSecond : string
•ColThird : string

I want to develop a mapping that ETLs these three files into this one database, but because the column names are different, it looks like I'll have to develop three different mappings, or three different sources, or three different somethings. The problem is that my example is contrived: I actually have many different files that all have different formats and column names, but the data is all very similar.

I would like to develop a single mapping or workflow that can handle all of this by only adding a table that holds the column mappings. Such a table would look like this based on the sample files and sample table above:

TableMappings:
enter image description here

In this way, to edit a column mapping I only have to make an edit this this TableMappings table. I wouldn't have to make any changes at all to the mapping or workflow. Nor would I have to redeploy an application.

What would a mapping or workflow look like that could take advantage of something like this? I assume there'd be a flat file source that takes files from a folder. There would be something in the middle that uses this TableMappings table to map column names. Finally there would be a relational data object that represents my destination database table "TableDestination". I don't know how to put this together though.

I have simple informatica(9.1) mapping(one to one) which loads data from flat file to RDBMS

it take 5 mins to load to Oracle db and 20 mins to load same file in SQL Server 2008 R2.

Can there be any source/pointers for performance improvement

For cleaning up unused IPC-Sources I need a Repository Query for getting Workflow, Session, Mapping and Source/Target of Mapping.I have startet by joining REP_LOAD_SESSIONS and REP_TBL_MAPPING on mapping_id but only a fraction of mappings seem to be present in the joined output. I can't find the right tables to join to get the job done. Any help will be greatly appreciated!

I have almost 40 mappings to be created with similar structure. Instead of creating them individually, I was considering that I generate a template in Visio and then generate the mappings using the mapping template.

However, the column names in my source and targets are not consistent. Can I get a drop down while generating the mappings as we get while generating SCD mappings using templates?

Thanks a lot.
