Ora-12154 :tns: could not resolve the connect identifier specified
Posted by Chris Pollach on 05 September 2014 09:50 AM


PB database profile showing ora-12154 :tns: could not resolve the connect identifier specified in 64-bit system.

Connection from Developer fails as well.



This is caused by a Oracle bug. Oracle connection doesn't allow parentheses "(" and ")". These parentieses may cause conflict. 

This happens when the PB or Appeon Developer is installed under C:/Program Files (x86)...



1. Please install new client. If you use, you will need Patch 4: Apply Patch 4923787 or later.

2. Please install PB and Appeon Develeper to other directory.
