Meta data is data about data. Power Center 6x / 7x creates
155 / 183 tables, when informatica is installed on an
environment. These tables contains all information of
transaction / changes done in Informatica.
Eg: we can find all the mappings / transformations - last
modified time / last successful run time etc. These tables
will usually have the naming convention OPB_.....
These objects / tables are created under schema pointing to
the database connection hich is provided when Power center
is installed

Hi, I have one flatfile as target in a mapping . When i am trying to load data second time into it. The records already is in flatfile is getting override. I don't want to override existing records. Note : we can do this by implementing CDC / Incremental pool logic if target is relational . But this is flatfile. So, even i use this same technique it will override only So what is the solution ? Is there any option at session level for flatfile target ? Advance Thanks
