IO Error: Size Data Unit (SDU) mismatch.

Hello Team ,

I am just reported an error ( IO Error: Size Data Unit (SDU) mismatch ) from the application team .

This is the consequence of an upgrade from 11.2.0.2 to 11.2.0.4 of oracle software .

I've gone through few docs and found that as

---Upgrade to 12c Driver (12.1.0.1 or above).

OR

-----Reduce SDU size to less than 32804 in 11g Release2 Driver.

When the configured values of client and database server do not match for a session, the lower of the two values is used.

You can modify SDU size either setting of Client(SID) and Server(DEFAULT_SDU_SIZE).

 

I would like to go with --- modify SDU size either setting of Client(SID) and Server(DEFAULT_SDU_SIZE) .
