Oracle11g installation and configuration EM

Oracle11g installation and configuration EM

You cannot log on to EM. If you execute emca-config dbcontrol db, you do not know that the default port number is 1522. But google will execute the command in step 2... (My listeners are fine)

1. Open the Net Configuration Assistant in the oracle Configuration tool, select "Listener Configuration", next, select "reconfigure", and next, check whether the parameters configured in each step are correct.
2. Run the "emca-deconfig dbcontrol db" command on the command line to delete the configuration.
3. Run the "emca-repos drop" command to delete repository.
Note: Steps 2nd and 3 are required. Otherwise, the installation fails due to an error "ORA-20001: SYSMAN already exists .." reported when you reinstall EM.
4. Run the "emca-config dbcontrol db-repos create" command to create em.
After completing the preceding steps, you have successfully created em. Click the Database control-orcl connection in the oracle folder on the Start menu to access em normally.
Note that the address for accessing em when I first installed oracle is https: // localhost: 1158/em. The port number here is 1158, now, when I re-create em, the port number after the link becomes 5500.
