Question
I am looking for some help about performance issues while replicating data from oracle into teradata.
The replication took 9 hours 37 seconds for replicating 36.44GB, which corresponds to about 164918245 records
So far I see one suggestion is to split the connection between streams but this is not so-far doable in my use case.
I have attempted to give 4GB memory for the main jobs and added JDBC parameter XX:MaxRAMPercentage=75.0 - but I haven’t noticed major performance improvements
Has someone had similar experiences in the past? how to address these performance issues?
