can not create directories like adump etc

 I was trying to create a database instance using DBCA in 10G. After selecting all parameters, small window pops up and says cannot create adump directory. Do I have to create all these directory manually before I run DBCA or what. I am running dbca from oracle login account.

It's pretty much giving the same error like cannot create some directories or some files for everything it's supposed to create atutomatically. I am able to create mannually all these directories but why DBCA can't create these automatically otherwise no point in creating database through DBCA. Am I missing something here
