Weblogic com erros de Numberformating

Retirado de: http://www.programmingforliving.com/2012/08/weblogic-server-failed-during.html

We have been seeing frequent occurence of this issue recently with WLS 10.3. Hence I am re-posting it with the solution.

Exception: 

1 2 3 4 5 6 7 8 9 10

Server failed during initialization. Exception: java.lang.NumberFormatException: null    Java.lang.NumberFormatException: null    At java.lang.Integer.parseInt (Integer.java: 436)    At java.lang.Integer.<init> (Integer.java: 609)    At weblogic.ldap.EmbeddedLDAP.validateVDEDirectories (EmbeddedLDAP.java: 1069)   At weblogic.ldap.EmbeddedLDAP.initialize (EmbeddedLDAP.java: 196)    At weblogic.t3.srvr.T3Srvr.initializeHere (T3Srvr.java: 816)    At weblogic.t3.srvr.T3Srvr.initialize (T3Srvr.java: 670)    At weblogic.t3.srvr.T3Srvr.run (T3Srvr.java: 344)    At weblogic.Server.main (Server.java: 32)

Solution: 

1. Edit bea_home/user_projects/domains/your_domain/servers/your_server/data/ldap/conf/replicas.prop
   
   Please note that you will have to replace bea_home, your_domain and your_server with actual values of your weblogic server installation.
2. Delete the content of the file and add the following 
   1	replica.num=0

3. Start the Server

E Não é que funciona?!
