Multiple lookups in one Lookup Stage

Good afternoon DSXchangers, Is it a red flag if I use 1 lookup stage to do multiple different lookups in terms of performance? I am essentially using one lookup stage instead of many lookup stages to do lookups against different tables. The algorithm is simplified as below. Stream ----Only LookUp St...

Job Run Condition

Hi All, I have a sequencer which is already in place. We have realised that the job was runnig for tomorrow if accidentally ran by the support team. This job gets its date from a table which holds run date for the job. For instance : if the job ran for today and when accidentally some one runs it ag...

Good evening, The commit level was set to 1. The table had HASH partition enabled while in Parallel mode of execution. The job basically does a select from a source table, a lookup with 5 other tables and finally does an insert into the target table abcd(this table was getting geadlocked due to conc...

Hi all,

I am not sure if this can be called a resolution. However, the solution came by changing the process flow of the active stages from parallel to sequential.

Thanks,

Ray, the table abcd(the one that is getting locked) does not have a select in this job other than an insert(which is failing).There are 5 other Oracle tables that have a select performed on them.

Thank you,
Mukthi

Yes Ray, the job has select in itself which occurs when it looks up with 5 Oracle tables then the output from the lkp gets inserted into the table abcd(Table that is getting locked).

Thank you,

I did not find any concurrent process running on that table and hence was I intended to check for the transaction commits.

Transaction handling in Parallel jobs

Hi everyone, I have a parallel job that has failed due to a deadlock on one of the Oracle tables into which the job does inserts. The approach I adapted was to see if there was any concurrent process that does any modification to the table and found out to be none. But, I am not sure about the trans...

However,if I schedule the job to run for just today then it goes on fine.But,not when I want to run them on a daily/weekly b...
