I am running ORACLE 8i database. I start DBA studio and want to use backup manager. but when i click on this item a message appears that shows that you can only use this option when ORACLE Management Server is running. i configured the OMS and start it. but when i want to logon to Management Server an error message appers "EMSDK-1100 unable to make a secure communication channel".
Pl briefly describe , what should i do more to logon to OMS and ulmitely use backup manager in DBA studio.
