Socket read timed out upgrading oracle ebs to 1211
I am upgrading Oracle E-Business Environment from 11.5.10.2 to 12.1.1. We have already upgraded database from 9.2.0.8 to 11.1.0.7 and now I am applying the driver u6678700.drv (American Englishupgrade patch driver) according to Chapter 3 step 10 of "Upgrading 11i to 1211.
After the adpatch was running for hours I saw that half of the worker seemed hang out. In theri log (I am going to attach it) I found the following error:
Exception in thread "main" java.sql.SQLException: Socket read timed out
Caused by: oracle.net.ns.NetException: Socket read timed out
