The experience of configuring Oracle EM at once

The Oracle10grac configuration of EM, originally a very simple thing, but it took a long time, recorded, Memo.

The first is to report the following error:

Online data search is a bug for Oracle.

Oracle's explanation for this is:

In Enterprise Manager database Control with Oracle Database 10.2.0.4 and 10.2.0.5, the root certificate used to secure COM Munications via the Secure Socket Layer (SSL) protocol would expire on 31-dec-2010 00:00:00. The certificate expiration would cause errors if you attempt to configure Database Control on or after 31-dec-2010. Existing Database Control configurations is not affected by this issue.

IF you plan to configure database Control with either of these Oracle Database releases, Oracle strongly recommends that Y ou apply Patch 8350262 to your Oracle Home installations before you configure Database Control. Configuration of Database Control is typically do when you create or upgrade Oracle Database, or if you run Enterprise M Anager Configuration Assistant (EMCA) in standalone mode.

can view: Enterprise Manager Database Control configuration-recovering from Errors Due to CAS expiry on Oracle Database 10.2.0 .4 or 10.2.0.5 [Video] [ID 1222603.1]

Workaround:

If you have already made this patch before creating an instance, you will not be able to make an error after that. If this patch was made after the instance was created, you need to do the following:

for single-instance:
1. Installing Patch 8350262 with Opatch
2. Set the Oracle_home and ORACLE_SID environment variable to execute the <patch_home>/killdbconsole. (This step is omitted from the Windows platform)
3.re-secure Database Control with the following command:
<oracle_home>/bin/emctl Secure Dbconsole-reset
4.re-start Database Control with the following command:
<oracle_home>/bin/emctl Start Dbconsole


for RAC:
1. Install patch 8350262 with Opatch and install on one node is OK.
2. Execute on ALL nodes: set Oracle_home and ORACLE_SID environment variable, execute <patch_home>/killdbconsole. (This step is omitted from the Windows platform)
3.re-secure Database Control on the first cluster node with the following command:
<oracle_home>/bin/emctl Secure Dbconsole-reset
4.re-secure Database Control on the remaining cluster nodes with the following command. Note that The-reset switch was not included with the This command:
<oracle_home>/bin/emctl Secure Dbconsole
5.re-start Database Control by executing the following command on each node in the cluster:
<oracle_home>/bin/emctl Start Dbconsole

After patching, clear and new EM, a variety of error, helpless under the manual deletion of various data:

After the new EM succeeds,
