Cannot configure EM Database Control

I have two Oracle 10gR2 instances running, PROD and ACPT. ACPT is alledgedly a clone of PROD made some 9 months before I came on board this project. I need to get EM DB Control (Not Grid Control) running on ACPT. After reviewing the clone procedures they say they followed to create it, I cannot vouch for the viability of the ACPT instance. It is running, can be accessed by SQL Developer, SQL*Plus, and other web-based interfaces. But EM will not connect to it. I have tried EMCA ... -repos recreate, -repos drop/create, and get nothing but a bunch of errors. -repos create crashes trying to create the SYSMAN account (which was successfully dropped by RepManager). The CREATE USER SYSMAN command generates an error from TNS, saying an unsupported action was attempted.
It is interesting to note that, on PROD, emctl status agent says the agent is running and ready, but, just like on ACPT, emctl status dbconsole says that OEM 10g is not running. I say interesting because I am simultaneously connected to the EM it says is not running.
I do not much trust the configuration of ACPT, mainly because of the OEM problems, but also because there seem to be steps missing in the roadmap they followed to create it. There is no mention of OEM anywhere in it, and this seems odd.
The client is, by choice, not running Grid Control anywhere, just individual DB Control isolated in each instance. This should be fine, but there has to be something to adjust concerning EM when cloning such a DB.
What am I missing, or where am I expecting something unreasonable?? RepManager effectively deleted the <hostname>_ACPT directory structure (although had made a copy before it did so). It also dropped the SYSMAN schema and its objects. But emca -config dbconsole db -repos create craps out as I mentioned above.

You have made several references to "errors", but have not seen fit to actually share any specific error with us. We can certainly help you get dbcontrol configured, but we have to know exactly what commands you issue and exactly what error messages are returned. Copy and paste from a terminal session can be quite helpful.

Configuring EM Database Control when database is running on different IP

OS Solaris
DB Oracle 10.2.0.2
The have the following situation:
We have a veritas active/passive cluster. This is not RAC. Server name is abc. But the database is running on VIP xyz. How do I configure database control to run on vip xyz. whenever I run emca -config dbconsole db, it always sees the server name as abc.
I also tried emca -config dbconsole db -HOST xyz but finally it always shows the hostname as abc.
I was able to get EM to see the targets (database, listener) properly on the vip xyz by manually editing the targets.xml file. So now the situation is, on the home page it shows that the datbaase is up and the listener is up, but it complains that it cannot connect to the database.
I really appreciate any help in this.

DBConsole installs requiring different hostnames (virtual) than the physical hostname, simply set ORACLE_HOSTNAME variable to the new virtual hostname and run emca.
in detail please read this note , it might help you
Configure DB Control 10.2 for use in Active/Passive High Availability Environments
Overview and Requirements:
In order for the DB Control to service a database instance after failing over to a different host in the cluster, the following conditions must be met:
1. Install on a shared disk/volume which holds the binaries, the configuration and the runtime data (including the database). Installations on non-shared devices are not supported.
2. Configuration data and metadata must also failover to the surviving node
3. Inventory location must failover to the surviving node
4. Software owner and timezone parameters must be the same on all cluster member nodes that will host this database
Installation and Configuration:
• In order to override the physical hostname of the cluster member with a virtual hostname, you must use the parameter ORACLE_HOSTNAME to configure DBConsole
• For inventory pointer, software must be installed using the commandline parameter ‘-invPtrLoc’ to point to the shared inventory location file, which includes the path to the shared inventory location.
• The database software, the configuration of the database and DB Control is done on a shared volume.
Note: The use of OCFS V1 to install shared Oracle binaries is currently not supported.
If you are using an NFS mounted volume for the installation, please ensure that you specify rsize and wsize in your mount command to prevent running into I/O issues.
See Metalink Note <279393.1>
Example:
lxdb.acme.com:/u01/app/share1 /u01/app/share1 nfs rw,bg,rsize=32768,wsize=32768,hard,nointr,tcp,noac,vers=3,timeo=600 0 0
A. Setup the alias for the virtual hostname/virtual IP address
You can do this by either allowing the clusterware to set it up, or manually before installation and startup of Oracle services. This virtual hostname must be static and resolveable consistently on the network: All nodes participating in the setup must resolve the virtual IP address to the same hostname. Standard TCP tools like nslookup and traceroute can be used to verify.
B. Setup shared storage
This can be storage managed by the clusterware that is in use or, you can use any shared file system (FS) volume as long as it is not an unsupported type, such as OCFS V1. The most common shared FS is NFS.
C. Setup the environment:
Some OS versions require specific OS patches to be applied prior to installing 10gR2. The user installing and using the 10gR2 software must also have sufficient kernel resources available. Refer to the installation guide for more details.
Before you launch the installer, certain environment variables need to be verified. Each of these variables must be set identical for the account installing the software on ALL machines participating in the cluster:
• OS variable TZ
Timezone setting. Recommended to unset this prior to the installation
• PERL variables
Variables like PERL5LIB should be unset to prevent the install (OUI) and DB Control to pick up the wrong set of PERL libraries
• Paths used for dynamic libraries
Based on the OS, the variables can be LD_LIBRARY_PATH, LIBPATH, SHLIB_PATH or DYLD_LIBRARY_PATH. These variables should ONLY point to directories, which will be visible and usable on each node of the cluster.
D. Ensure that oracle user name, ID and group name and ID are in sync on all cluster members
The user and group of the software owner should be defined identically on all nodes of the cluster. This can be verified using the ‘id’ command:
$ id -a
uid=1234(oracle) gid=5678(dba) groups=5678(dba)
E. Ensure that inventory files are on the shared storage
1. Create your new ORACLE_HOME directory.
2. Create the Oracle Inventory directory under the new oracle home
cd <shared oracle home>
mkdir oraInventory
3. Create the oraInst.loc file. This file contains the Inventory directory path information needed by the Universal Installer.
a. vi oraInst.loc
b. Enter the path information to the Oracle Inventory directory, and specify the group of the software owner as the dba user:
Example:
inventory_loc=/app/oracle/product/10.2/oraInventory
inst_group=dba
F. Start the installer:
You need to point to the inventory location file oraInst.loc (under the ORACLE_BASE in this case), as well as specifying the hostname of the virtual group. Debug parameter is optional.
runInstaller -invPtrLoc /app/oracle/share1/oraInst.loc ORACLE_HOSTNAME=lxdb.acme.com –debug
G. Update the SPFILE and tnsnames.ora file
Add an listener entry to the spfile file that points to an entry in the tnsnames file calling the virtual IP directly. As an example, set a tnsnames.ora entry that points to the virtual host name:
LISTENER_DBC =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = lxdb.acme.com)(PORT = 1521))
Then update the spfile parameter local_listener to point to the new tnsnames.ora entry:
SQL> alter system set local_listener='LISTENER_DBC';
SQL> show parameter local
NAME TYPE VALUE
local_listener string LISTENER_DBC
H. Startup of services:
Ensure that you start your services in the proper order:
- establish IP address on the active node
- start the TNS listener
- start the database
- start dbconsole
- test functionality
In case of failure…
- Establish IP on failover box
- start TNS listener lsnrctl start
- start the database dbstart
- start dbconsole emctl start dbconsole
- test functionality
If you want to manually stop or shutdown a service:
Stop the application
Stop DB Control emctl stop dbconsole
Stop TNS listener lsnrctl stop
Stop DB dbshut
Stop IP

Database control won't run in secure mode

I'm following the instructions displayed by the database configuration manager after creating a database. These instructions configure the database control to run in secure mode using https. I get an error with the following command run from the OS command line while in the ORACLE_HOME/bin directory:
emctl.bat secure dbconsole -sysman_pwd password
I get the error message "Failed to create EM root key."
The emdctl.trc file has the following entry: "No connection could be made because the target machine actively refused it."
The ORACLE_SID has already been set. The database control is down. The "emctl config emkey -repos" command completed successfully.
I'm using Oracle 10.2.0.4 on Windows 2003 server. I'm running this command on the database server. The database control was selected in the database configuration manager. This database control does run successfully in http mode, but I can't configure it for https.
Does anyone know why the target machine would actively refuse this connection?

Have you tried it without the -sysman_pwd flag ?

Database control hangs in Workshop Tutorial !!!

Hi,
I am using WLS 7.0.1.0/SP1 ( latest version ) with Workshop included, on Windows
XP Prof. In Workshop Tutorial, Step 3, the test hangs at the execution of
Applicant dbApplicant = bankruptciesDB.checkForBankruptcies(taxID);
I am asking if it is a known problem? There may be several reasons for this and
it is too expensive to investigate all of them:
1. Tutorial text misses a fragment describing special configuration for the Database
control
2. Tutorial is correct but default ( installation ) configuration of Database
control has bug(s)
3. A helper class, implementing BankruptciesDatabaseControl interface, is missed.
4. Implementation of Database control is buggy. What the magic happens when I
“SELECT TAXID, FIRSTNAME, LASTNAME, CURRENTLYBANKRUPT FROM BANKRUPTCIES WHERE
TAXID={taxID}”, i.e. only a sub-set of “Applicant” attributes in the query, and
how Database control ( using my interface method public Investigate.Applicant
checkForBankruptcies(String taxID) ) knows which database table field to map to
which Applicant” attribute ? [I suppose, creation of “Applicant” class is independent
from the database schema, isn’t it ?]
Thank you,
- Michael

Sure, I will send you the dump. Please, provide me with your e-mail.
As of column names, don’t you find it error-prone approach where a developer has
to “find” the names and type them into the code ? Since you are already deal with
a db adapter/controller, I suggest, the adapter has to read a db schema, gets
the column names and data types. In other words, I would expect in this case the
same functionality as provided by, e.g., TogetherSoft’s Control Center. It creates
Entity Beans out of the db schema and only then allows you to manipulate them.
Thank you and wait for your e-mail.

Michael,
The names of the elements in the 'Applicant' class should match one-on-one
with the database column names in the corresponding table.
I guess you are using the default Pointbase database. Can you check whether
you were able to create successful connections to the Pointbase database
during server startup?
If the server is hanging at the statement you have mentioned, can you
take a
thread dump by using Ctrl->Break and email it to me.
Thanks,

Question about Note 870814.1 - Backing up EM Database Control Data

Quick question -- why would you want to downgrade OEMDC after upgrading to 11gR2?
"After upgrading to Oracle Database 11g release 2(11.2), if you want to downgrade Oracle Enterprise Manager Database Control you must save your Database Control files and data before upgrading your database."

If you want to keep your current database control configuration after a downgrade you have to save this configuration before downgrading. Otherwise - after the downgrade - you would have a clean configuration. Database control continue to work, but it starts a new incarnation.

With Windows Server 2003 I haven't any problems with the configuration of database control over cmd.
Any Ideas?

Please run the following command
cmd>net start OracleDBConsolexxx(Assume sid name=xxx
cmd>set oracle_sid=xxx
cmd>emca (You will get all related keyword of emca)
Firstly you have to check that if you have created your database through DBCA then you have to drop old repository or recreate repository:
To drop (remove) the configuration files and repository for Database Console, run:
cmd>emca -deconfig dbcontrol db -repos drop
To recreate (remove & create) the configuration files and repository for Database Console, run:
cmd>emca -config dbcontrol db -repos recreate
(Please mark it helpful/Answered if you get solution)

Oracle Enterprise Manager Database Control VS Grid Control

What is difference of Oracle Enterprise Manager Database Control and Oracle Enterprise Manager Grid Control?
How I can install it manually?
Thanks

What is difference of Oracle Enterprise Manager Database Control and Oracle Enterprise Manager Grid Control?
How I can install it manually?Dbcontrol is for single database as Grid control is for multiple databases.Dbcontrol has limited features than Grid control that goes beyond database administration to monitor other targets that include Operating system and application servers, web application, High availability (data guard) configurations. Database control comes with oracle server license but Grid control is a separate product it required separate license. If you want to use basic features then you can turn off the licensed packs in Grid control and use free product.
Install Grid Control as doc:http://download.oracle.com/docs/cd/B16240_01/doc/em.102/e10953/installing_em.htm

Database Control Install

I'm running a 10.2 instance on Solaris, and need to install DB Control on a Windows box for management. What install disk/download does it come from? It's been about a year since I setup DB Control. I thought it was on the companion CD, no?

Here is a good article on the emca command:
The emca tool that is available in 10.2 Database install uses different options than the emca shipped for 10.1. Below is the output from the help file for the 10.2 emca utility:
1. Set the $ORACLE_HOME to the 10.2 Database home.
2. To get a list of options, issue the command: emca -h

!!!! Urgent Database Control Not working, Plz help !!!!!

Hi,
I have a webservice and in the same server(weblogic 9.2) a data source(cgAppSource) is configured. the database control is not instanciating properly, it is always remains null despite the calling of webservice. I am getting NullPointerException in the webservice. First time I am using annotation to execute a SQL query. It is urgent.can anyone please help me. what code change I have to do in both the files.
SampleDatabaseControl.java -
package control;
import java.sql.SQLException;
import org.apache.beehive.controls.api.bean.ControlBean;
import org.apache.beehive.controls.system.jdbc.JdbcControl;
@org.apache.beehive.controls.api.bean.ControlExtension
@JdbcControl.ConnectionDataSource(jndiName="java:comp/env/jdbc/cgAppSource")
public interface SampleDatabaseControl extends JdbcControl ,ControlBean{
 static final long serialVersionUID = 1L;
@JdbcControl.SQL(statement="SELECT SYSDATE FROM DUAL")
public String returnSysDate() throws SQLException;
The webservice : ControlWebservice.java
package service;
import javax.jws.WebService;
import javax.jws.WebMethod;
import javax.jws.soap.SOAPBinding;
import weblogic.jws.WLHttpTransport;
import org.apache.beehive.controls.api.bean.Control;
import control.SampleDatabaseControl;

 use=SOAPBinding.Use.LITERAL,
 parameterStyle=SOAPBinding.ParameterStyle.WRAPPED)
@WLHttpTransport(contextPath="ControlWebserviceProj", serviceUri="ControlWebservice",
 portName="ControlWebservicePort")
public class ControlWebservice {
 @Control
 private SampleDatabaseControl SampleDatabaseControl;
 @WebMethod()
 public String returnDate()
 String returnValue = null;
 try{
 returnValue = "This message sent date :" + SampleDatabaseControl.returnSysDate(); // getting null pointer Exception here.
 catch(Exception e)
 e.printStackTrace();
 return returnValue;
}

Hi james,
In that link it says to 'Create a Beehive-enabled Server Domain' in which On the second page(named Select Domain Source), I need to place a check in the Apache Beehive checkbox . But in my machine when I follow the steps I dont find any such checkbox in the (named Select Domain Source) page. Is this the problem? I can see only two check boxes. The page looks like......
Generate a domain configured automatically to support the following product. // radio select
Weblogic Server (Required) //check box
Workshop for Weblogic Platform // check box
Base this domain on an existing domain. //radio select
Templatelocation .... // a browse option
Do I need to do some other configuration to make beehive check box active in the page? All the beehive jars are present in the instalation. And as far as I remember I did the full instalation of Weblogic 9.2 after downloading from the bea site. and I am giving the beehive related jar

beehive-controls.jar,beehive-jdbc-control.jar,weblogic-jdbc-control.jar in the lib folder wnder WEB-INF and deploying.

How to configure EM Grid Control for more than one databases?

Hi,
I'm configuring EM on Oracle 10gRel1 on Linux. I have more than one databases in the server, and I want use IE at my PC to monitor the databases on Linux server. I can configure and access the Grid Control Console by emca for first database, but cannot configure for the second one, unless I remove the first one configurration. How can I configure EM for more than one databases?
Thanks.

Thank you everybody.
Yes, I'm talking about DBConsole rather than Grid Control (sorry for misuse the term). I managed to set up DB Console for every DB in the same Linux box (10Rel1). What I did is:
1) stop db console and agent with emctl
2) remove repository with RepManager
3) config with emca
Then I can monitor individual databases from my PC (but have to login with different port).
I'm thinking mybe I should use Grid Control instead.
