I have a source table in oracle that contains a column (Nclob) that have XML messages and my target is BW data souce
I build my job like that
Source Table------Quey1 (to convert to varchar)-------------Query2(Unnest XML using extract_xml)-----------------BW Target
I successfully running the job with small test data in source (About 100,000 records) takes about 30 minutes
But when I running with the actual table contains about 140000000 it takes so long time my be more than 12 hours and never ending and it is affect the job server so I decide to kill the job
I checked the log I found that the job running in im memory mode instead of peagable because it is nested schema
I need help to enhance this job and let running successfully
