changing pswds of standard accounts

Platform: Ora EE 10.2.0.2.0 on HP-UX

We have a directive to change *all* passwords every 150 days, so I am looking at all of the Oracle 'standard' accounts. I know there are special considerations for DBSNMP and SYSMAN. Looking at MetaLink note 160861.1 and some of the links from there, I'm getting a mixed bag of suggestions on the others -- usually either a simple change with no real effect, to vague descriptions of what the account is for and no mention of considerations for password changes.

Here are the accounts in question, that exist on our system:

MGMT_VIEW MDSYS (oddly, MDDATA and CTXSYS, which seem to be associated, do not exist)
ORDSYS
ORDPLUGINS
SI_INFORMTN_SCHEMA
WMSYS
ANONYMOUS
XDB
EXFSYS
DIP
TSMSYS I'm not even sure the features associated with some of these are even being used, but my question here is do any of these pose problems with changing the passwords (like exist for DBSMNP - password is baked into some other files or procedures) or can they simply be changed like any other user account?
