Willy,
These scripts were intended for Oracle version 9 & 8 where there was performance problems on some dictionary views (see note 519407 ).
This is not a problem any more, to the point that pre-pgrade scripts now removes the workaround solution created by scripts from note 558197
So if you are in 11g do not even bother about these scripts...
1431793 - Oracle 11.2.0: Upgrade Scripts
Added 1. April 2011
If in the past the database views SAP_USER_INDEXES, SAP_USER_IND_COLUMNS and corresponding synonyms have been created and still exist in your database, you need to drop them before you upgrade to release 11.2 (check SAP note 519448). This clean up task is included in the current version of upgrade scripts for release 11.2.0.2 (available April 2011).
By the way dictionary stats are computed by the pre-upgrade scripts from note 1431793 - Oracle 11.2.0: Upgrade Scripts so it is not necessary to manually update these stats.
Regards
