It would be great if one of you can explain me in brief what is the function of xfr (like what does it do ,where is it stored ,how does it affect ) as i am very confused on thisthank you
Latest Answer: The XFR usually stores the mappings in the text view. Usually these mappings are generalised. In the Transformation of any component these XFR's can be called and abi nitio will automatically do the specified mapping as stored in XFR. The main benefit ...
Latest Answer: I think i misunderstood the question ,there are 3 type of parallelisms in Ab Initio , details of 3 types are expalined correctly above with difference. ...
I want to use an Ab Initio parameter to control whether I am in serial or MFS mode. Basically, I will have an $AI_MFS_PARTS variable. If it is set to 1, then we are running serial. If it is set to 4,
Latest Answer: Its always better to use multiple file system instead of adhoc multifiles.So,physical allocation is a good idea for separation of mfs and serial.Say,i have a physical allocation to path1 for mfs and have the m_mkfs //host/abhi/mfs4 //host/delphi/a/mfs4-0 ...
How can I calculate the total memory requirement of a graph?
Latest Answer: When we did some benchmarking we found that it was closer to ~8MB + MAX_CORE (if any) per component and add in the file sizes.Basically, I agree with the existing answer.Just remember, don't use "in-memory" components if you think the total ...
How can I achieve cummulative sumary in AB Initio other than using SCAN component. Is there any inbuilt function available for that?
Latest Answer: There are three ways1) You can use Scan with rollup component2) Use Rollup component 3) You can also use Scan followed by Dedup sort and select the last record. That will solve the purpose ...
I have file containing 5 unique rows and I am passing them through SORT component using null key and and passing output of SORT to Dedup sort. What will happen, what will be the output.
Latest Answer: If there is no key used in the sort component, while using the dedup sort the output depends on the keep parameter.If its set to firt then the output would have only the first record,if its set to last the output would have the last record,if its set ...
If I have 2 files containing field file1(A,B,C) and file2(A,B,D), if we partition both the files on key A using partition by key and pass the output to join component, if the join key is (A,B) will it
Latest Answer: I do not think the join output would be correct. The partition key fields for the two input streams should be same as the join key fields in the join component, otherwise the data from stream 1 would be partitioned in a different way than data from stream ...
There is one MF while loading data i deleted one partition in a MF? Can it show error/it will process data?
