Oracle cannot use EM's solution, as follows

Can not log in to EM, execute emca-config dbcontrol db do not know always default 1522 port number, but, google some time, start from the second step below. (there is no problem with my monitoring)

1. Open Net Configuration Assistant in the oracle configuration tool, select "listener configuration", next, and then select "reconfigure". Next, carefully check whether the parameters configured in each step are correct on OK.

2. Use the "emca-deconfig dbcontrol db" command on the command line to delete the configuration

3. Use the "emca-repos drop" command to delete repository

Note: steps 2 and 3 should be done, otherwise "ORA-20001: SYSMAN already exists.." will be reported when reinstalling EM. Caused the installation to fail.

4. Use the "emca-config dbcontrol db-repos create" command to create the em.

After completing the above steps, you have successfully created the em. Click the Database control-orcl connection in the oracle folder on the start menu and you can access the em normally.

It should be noted here that when I first installed oracle, the address to access em was https://localhost:1158/em, where the port number was 1158, but now the port number after the address link after I rebuilt em has become 5500.

The above is the whole content of this article, I hope it will be helpful to your study, and I also hope that you will support it.
