Abinitio MFS
There is one MF while loading data i deleted one partition in a MF? Can it show error/it will process data?

yes the above point is also valid , if file does not exist , the ab initio will throw an error. If it is truncated ,you will loose the data but abinitio will not throw an error.

Did you delete data in partition or deleted partition itself?If data is deleted (or truncated) in a partition, ab-initio does not throw the error.If a partition itself is deleted, ab-initio is going to throw the error.

Best way is using the environment variable to set the values in dbc file. By this you can have the flexibility to change any variable value's by changing the evironment variable.

Good way doing this is, parameterize .dbc file. Parameter will have different values for different environment.

1. Make sure you have multifile system in your ab-initio environment2. Then use partition component to distribute your records to MF

Abinitio Bad-Straight-flow
When did we get error like 'Bad-Straight-flow'?
sixto.dsilva
- Apr 15th, 2008
It is error you get when there is mismatch in flow that is one is serial flow and other componet is mfs flow , the ab initio will complain about the bad flow and graph is will be aborted because of this. you should be using the partition component in order to avoid this.

Layouts problems in components. e.g. a straight flow connecting a component which is having serial layout with a component which is in muti-file layout.

Any graph in ab initio is a separate and independent entity in itself. First of all, there is no such concept of graph merging in ab initio, since it does not make any sense, and two graphs that are s...

Abinitio Partitions
What is the difference between partition, re-partition and departition?
sixto.dsilva
- Apr 15th, 2008
Partition is coverting a serial file(mfs) into multiple flows --> component used is partition by key or partition by round robin.departition is opposite of partition , sometime after the parallel processing , you want output to be serialized we using gather and merge component for this.

Dividing a single flow of records(data) into multiple flows is known as partitioning.Dividing a x-way flows of records(data) into y-way flows is known as re-partitioning.e.g: 2 ways flow ino 4 ways flowCombining multiple flows into a single flow of records(data) is known as departitioning.

Processing 1GB data with a small lookup file is good ... but to make the 1GB data as a lookup file is mistake.Use mfs lookups instead if its at most needed.

Indexes in Abinitio
In Abinitio which type of indexes used?
Sabitra S Panda
- Dec 10th, 2008
There is as such no concept of indexing in Ab Initio, since it is a code based ETL tool. Indexes come into picture on the database table side. But there is something called "output indexing" in Ab Ini...

I think we don't have any concept of indexes in ab inition , it is there only in Database like table indexing to improve query performance of the tables.In Ab initio it is only massive parallel processing concept.
