in Oracle client 12.1 used from .Net if Stored procedure output parameter is varchar then its values are getting truncated

i.e., Bug 21616079

As per KB article Doc ID 2101352.1 Bug 21616079  fixed in Windows bundle Patch 12.1.0.2.11 and higher

also fixed in Oracle client 12.2 https://docs.oracle.com/database/122/ODBCR/ODBCR.pdf

So we installed 12.2 but it did not help

is there anything else to do ?

Show that you are using 12.2 libraries with your .net code.
