Error test Database Connection and more strange things

Hi

I am installing a ECC6 and I get this error

ERROR 2007-11-29 16:58:58.333

FCO-00011 The step testDatabaseConnection with step key |NW_Onehost|ind|ind|ind|ind|0|0|NW_Onehost_System|ind|ind|ind|ind|1|0|NW_CreateDBandLoad|ind|ind|ind|ind|10|0|NW_ABAP_Import_Dialog|ind|ind|ind|ind|5|0|NW_ABAP_Import|ind|ind|ind|ind|0|0|testDatabaseConnection was executed with status ERROR .

I test the hostname and the dbname the same, I don't know what is the problem?

In addition in the screen to introduce the location of CDs with installation export ECC6SR2 appears 5 lines with the same description "INSTALLATION EXPORT 1 ECC6SR2", is it normal?

Thanks
