Description:
BWC installer hangs or fails if the DB password specified has special characters though SQLPlus allows using those characters.

If the DB password has special characters as $,%,\,etc, these may be valid in Oracle SQL Plus for logging, creating users but the BWC installer does not react well with these chars. The installer might fail or hang.

E.g.; Db password: bwctest$$, when you use this as username and password for BWC DB in oracle, you can successfully login using SQL Plus but the BWC installer failed. Tested with "\" in the DB password also was blocking the BWC installation, removing special chars helped.
