-

i have downloaded oracle developer days database 12c virtualbox image. can boot , access desktop. when try log in enterprise manager (em) express using url http://127.0.0.1:8888/em asked install adobe flash. install , login screen.

if try login system following error:

enter image description here

but when try log in user sys strange error: security token not match. must login again..

enter image description here

to me looks credentials sys ok, there wrong user in database. correct , if how can fix it? or em express not setup on image?

this document oracles metalink solves (https://support.oracle.com/epmos/faces/documentdisplay?_afrloop=185690872522025&id=1968763.1&_afrwindowmode=0&_adf.ctrl-state=16vhefh1mo_9). solution contains 3 steps.

  1. make sure xdb_wallet recreated succesfully.
  2. make sure xdb installed succesfully , appropriate roles, em_express_basic/all applied.
  3. use ie 11.0.9600.16476 compatibility view.

mark stewards answer covers step 2.

actually first 2 step not necessary. looks have been applied image. have use different browser. opera, chrome , ie works firefox doesn't.

but why oracle installs browser doesn't work em express , why adobe flash not installed when it's required strange.

but answer works me remote browser not image installed browser.
