The JDBC string lists the database host as localhost. Is that correct?
Are you able to login with new password through a third party client?
Please check and then update the password again if it was incorrect. Then try to bring up the Domain.
Logged in successfully with the new password in third party client (SQL server). But when i started Informatica 10.2.0 service it gives the error Login Failed.
Does the password contain any special characters (like diacritics, German Umlauts, or the like)? The rules for valid DB passwords which can be used in an Informatica domain are listed in the Installation and Configuration guide. For example, I would not be able to use the database password "München" (the German name of the city of Munich) thanks to the U diacritic.
