I would gladly get ERP experience given the opportunity whether it involves DBA work or not.
Here, there is currently a very strong demand for SAP consultants and a very weak demand for Oracle DBAs. In addition, Siebel, Peoplesoft, and Oracle Apps pros with DBA experience are in demand.
There is a steady demand for SAP R/3 Admins that have a very good grasp of Oracle Administration and Unix Administration. An SAP freelancer (Admin or non Admin) can expect an hourly wage (in Germany) that is significantly higher than an Oracle DBA or Developer.
Check out www.jobserve.com to gauge the demand.
