Oracle-emctl start dbconsole startup problem)

Solve the problem that the OEM cannot be opened

Emctl start dbconsole

Set oracle_sia = xsgj

Emctl start dbconsole

Set oracle_hostname = localhost

Emctl start dbconsole

Change the Oracle-> product-> 11.1.0-db_1> gmx-PC_XSCJ name to localhost_xscj

Change the oc4j_DBConsole_gmc-pc_XSCJ in Oracle> product> 11.1.0> db_1> Solaris> J2EE to oc4j_dbconsole_localhost_xscj.

The oracledbconsoleorcl service is stopped due to the following errors:
The specified path cannot be found.

The main cause is that the host name is changed or the IP address is changed. The corresponding file name is changed:

D: \ oracle \ product \ 10.2.0 \ db_1 \ Solaris \ J2EE \ oc4j_dbconsole_192.168.0.136_dgtest (change the new IP address or machine name)

D: \ oracle \ product \ 10.2.0 \ db_1 \ asdfjkl_dgtest (change the new IP address or machine name)

Find the port used by em in the D: \ oracle \ product \ 10.2.0 \ db_1 \ install \ portlist. ini file.

After the computer name is changed, all Oracle services cannot be started.
We recommend that you do not modify the computer name at will, because it is troublesome to modify many Oracle configurations after you modify the computer name.

My original computer name is 53m6df34f7.
The modified computer name is sgliuya2.

First, solve the oracledbconsole * service.
Run the command emctl start dbconsole In the CMD window and the following information is displayed:

C: \ Documents andsettings \ LiuYa> emctl start dbconsole
Oracle Enterprise Manager 10g Database Control release10.2.0.1.0

Is starting.
The oracledbconsolemap service cannot be started.

System error.
System Error 3.
The specified path cannot be found.

Some connections change the name of your computer, so you are prompted that the specified path cannot be found.
You can modify the corresponding configuration file to solve the problem, but it is too troublesome. You can use the following method to solve the problem:
Run the command in the CMD window: emca-repos recreate

C: \ Documents andsettings \ LiuYa> emca-repos recreate

Solution
The following are similar questions found in the Forum:
Solution for Oracle 10.2.0.3 RAC
1. Stop the dbconsole

2. Change <ORACLE_HOME>/sysman/admin/default_collection/rac_database.xml.
Lines (59-62) from
<Collectionitem name = "agentsideresponse" Upload = "no">
<Schedule>
<Intervalschedule interval = "5" time_unit = "min"/>
</Schedule>

To

<Collectionitem name = "agentsideresponse" Upload = "no">
<Scheduleoffset_type = "incremental">
<Intervalschedule interval = "5" time_unit = "min"/>
</Schedule>

3. Start the dbconsole and try again
