Host credentials in Enterprise Manager 11g are not accepted

Recommended Posts

I have Oracle 11g db. DBs are in two computers: virtual and local. I want to back up and recover in Enterprise Manager. Need to specify Host credentials. I enter Host credentials and button. The error appears: connection to host as user Administrator failed, connection refused: connect. Login of administrator, password is correct. In local policy administrator was added in Logon as batch job. Administrator was added in ora_dba. Administrator was added in users of oracle with sysdba privileges.
In EM preferences/preferred credentials through Host and Database Instance I specified Username, Userpassword, Host User and Host Password.    No results.
What to do? What else settings do I have to do?

 

Best Regards

Dear Sir!

I checked connection with ping, tnsping etc. The connection is normal. There is a connection in SQLPlus.

In EM all functions work except host credentials. No host credentials are accepted.

May be there is a specificity for virtual machine and local host.

My OS are WIN 7 and WIN 10.

Best Regards

Dear Sir!

Unfortunately our technical support is already over.

I said before that I added the “log on as a batch job” privilege already.

I noticed one thing. In EM the status of agent is unreachable.

Can it cause my error? If yes how to fix it?

Hi,

Have you verified that the agent process is running?

If you Google for “oracle OEM agent unreachable” you will see hundreds of pages from folks with the same problem!

It can be caused by dozens of configuration issues and by bugs.

If you need a patch you are out of luck.

This forum is intended for answering questions but you need an expert to work with you in detail to resolve your problem!

Since you let your support lapse, you can use a 3rd party to assist you.

If  you call 800-766-1884 you can get a certified DBA to help you troubleshoot the issue.  See details here:

Good luck!

I entered the command

emctl status agent

Output: Agent is not running.

emctl stop agent    or   emctl start agent

Output: list of all commands of emctl appears.

emctl upload

Output: Agent is not running.

We cannot invite an expert because our db is secret and we have restricted funds.

For emergency oracle support also need to pay.

We hope in Internet and forums.

I have one more question.

Can I use symbol hyphen "-" in hostname for EM? For example WIN-fgh245ak. My hostname is like that.

May be the error because of that. Certainly, I can change the hostname and other things but

I don't want to busy myself with it one more time.

I did what you said. Unfortunately it didn't help.

In forums they say the error "Agent is unreachable" can be fixed with the help of the note 271126.1.

Where can I find the info from the note in open access?

If "oracle" is a local account, then you need to set the credentials as "{localhost name}\oracle"

Otherwise if oracle is network account you need to set the credentials as "{local-domain name}\oracle"
