Hi,

I have worked in teradata connector stage as target.But I did not work as source. Now I need to use as source. For increase performence can I know the what properties I need to set.

arrry-size- 2000
record count-2000
access method- immediate
parallel synchronization- no

You're not really going to see performance improvement by working on the array size and the commit transaction. You could change the access method to bulk and then set the min and max sessions to settings recommended by your Teradata admins.

Hi,

Thanks your mail.
my job:

teradata connector stage -> transformer -> teradata connector stage

But I am getting below warnings and fatal error

Please help me out

after changeing to bulk mode I am getting above warnings and fatal error.

I set the MALLOC_CHECK_=0 in job level and administrator side also.

Now above warnings are gone. But job is kepping on running.

Please help me

What version of Teradata are you using and which Teradata Conector stage variant are you using? You can find the Teradata Connector variant when you open the stage.

Hi,

Job is keep on running because of Table is locked. But I am getting below error.

Take that error to your DBA.
