Tools used to manage Oracle databases include: http: // localhost: 1158/emhttp: // localhost: 5560/isqlplus. The iSQLPLus Service must be started first.> isqlplusctl start, but when I enter http: // when localhost: 5560/isqlplus/DBA, the Login Dialog Box appears, but the login fails. No matter which account is entered, the solution is recorded as follows. This is an operation in Windows: for my own situation, I first need to enter the Oracle directory, F: \ oracle \ product \ 10.2.0 \ db_1 \ Solaris \ J2EE \ ISQLPLUS \ Application-deployments \ ISQLPLUS, and then call the Java command to perform the next step.
