Dear Erman sir,

I have 19c (19.10.0.0) database with 12.1.3 ebs application, some long running concurrent request are failed with snapshot too old error.

Currently undo_retention is 2400 ,  I need to change it , what is the optimal value I have to assign here.

Make sure undo_retention size is cdb leval & pdb level are same , both in 2400.

Need your advice.

Regards,
Raiq
