Oracle EM Grid Control Agent Target Discovery

Oracle EM Grid Control Agent Target Discovery

Sometimes, you may install the 10g OEM GRID agent before you actually create a new database or you may add a new database to an existing box.

This new database will have to be discovered by GRID CONTROL.

I created a database called db11gr2 on a box which already had a Grid agent running on it.

This database has to be discovered by the agent and their details uploaded to the GRID.

Make sure the ORAINVENTORY location in /etc/oraInst.loc matches the location when you installed the AGENT.

Go to the new AGENT_HOME/bin and issue command agentca- d

[oracle@raclinux2 bin]$ agentca -d

Stopping the agent using /u01/app/oracle/OracleHomes/agent10g/bin/emctl stop agent

Oracle Enterprise Manager 10g Release 5 Grid Control 10.2.0.5.0.

Stopping agent … stopped.

Running agentca using /u01/app/oracle/OracleHomes/agent10g/oui/bin/runConfig.sh ORACLE_HOME=/u01/app/oracle/OracleHomes/agent10g ACTION=Configure MODE=Perform RESPONSE_FILE=/u01/app/oracle/OracleHomes/agent10g/response_file RERUN=TRUE INV_PTR_LOC=/u01/app/oracle/OracleHomes/agent10g/oraInst.loc COMPONENT_XML={oracle.sysman.top.agent.10_2_0_1_0.xml}

Perform – mode is starting for action: Configure

You can see the log file: /u01/app/oracle/OracleHomes/agent10g/cfgtoollogs/oui/configActions2010-03-05_08-33-08-PM.log

[oracle@raclinux2 bin]$

Now login to the database as sys, unlock the dbsnmp user and also change
the password of dbsnmp user – for example to temp.

Once this is complete, the GRID screen will show the
database on the targets page.

Creating physical standby in Oracle 10g

Creating physical standby in Oracle 10g

primary database name: 10gpri on raclinux2 server

standby database name: 10gsb on raclinux1 serverCreate a Physical Standby environment, General Review.

The Enviroment
     2 Linux servers, Oracle Distribution 2.6.9-55 EL i686 i386 GNU/Linux
     Oracle Database 10g Enterprise Edition Release 10g R2
     ssh is configured for user Oracle on both nodes
     Oracle Home is on identical path on both nodes
Implementation notes:
     Once you have your primary database up and running these are the steps to follow:
     1. Enable Forced Logging
     2. Create a Password File
     3. Configure a Standby Redo Log
     4. Enable Archiving
     5. Set Primary Database Initialization Parameters
     Having followed these steps to implement the physical standby you need to follow these steps:
     1. Create a Control File for the Standby Database
     2. Backup the Primary Database and transfer a copy to the Standby node.
     3. Prepare an Initialization Parameter File for the Standby Database
     4. Configure the listener and tnsnames to support the database on both nodes
     5. Set Up the Environment to Support the Standby Database on the standby node.
     6. Start the Physical Standby Database
     7. Verify the Physical Standby Database Is Performing Properly
physical standby manually.implementconfiguration is necessary to additionalsuccessfully and no is installed, Oracle database are met, that accommodate an Oracle database. All prerequisites raclinux2and raclinux1Manually setting up a Physical standby database is a simple task when all prerequisites and setup steps are carefully planed and executed. In this example We use 2 hosts,

10GPRI

SQL> select name from v$datafile;

/u01/app/oracle/oradata/10gpri/system01.dbf

/u01/app/oracle/oradata/10gpri/users01.dbf

SQL> show parameters unique

NAME TYPE VALUE
———————————— ———– ——————————
db_unique_name string 10gpri

Enable Forced Logging
In order to implement Standby Database we enable ‘Forced Logging’.
This option ensures that even in the event that a ‘nologging’ operation is done, force logging takes precedence and all operations are logged into the redo logs.
SQL> ALTER DATABASE FORCE LOGGING;
Database altered.
Create a Password File
A password file must be created on the Primary and copied over to the Standby site. The sys password must be identical on both sites. This is a key pre requisite in order to be able to ship and apply archived logs from Primary to Standby.

[oracle@raclinux2 ~]$ cd $ORACLE_HOME/dbs
[oracle@raclinux2 dbs]$ orapwd file=orapw10gpri password=oracle force=y

SQL> select * from v$pwfile_users;

USERNAME SYSDB SYSOP
—————————— —– —–
SYS TRUE TRUE

Configure a Standby Redo Log
A Standby Redo log is added to enable Data Guard Maximum Availability and maximum Protection modes. It is important to configure the Standby Redo Logs (SRL) with the same size as the online redo logs. In this example I’m using Oracle Managed Files, that’s why I don’t need to provide the SRL path and file name. If you are not using OMF’s you then must pass the full qualified name.

SQL> select group#,type,member from v$logfile;

SQL> select bytes from v$log;

Set Primary Database Initialization Parameters
Data Guard must use spfile, in order to configure it we create and configure the standby parameters on a regular pfile, and once it is ready we convert it to an spfile.
Several init.ora parameters control the behavior of a Data Guard environment. In this example the Primary database init.ora is configured so that it can hold both roles, as Primary or Standby.

Standby Database Steps
Here, we are going to create standby database using backup of the primary database using rman.where in comparison to user managed backup, rman is comfortable and flexible method.

Create an RMAN backup which we will use later to create the standby:

[oracle@raclinux2 ~]$ . oraenv
ORACLE_SID = [orcl] ? 10gpri
[oracle@raclinux2 ~]$ rman target=/

Recovery Manager: Release 10.2.0.1.0 – Production on Wed Jan 20 18:41:51 2010

connected to target database: 10GPRI (DBID=3603807872)

RMAN> backup full database format ‘/u01/app/oracle/backup/%d_%U.bckp’ plus archivelog format ‘/u01/app/oracle/backup/%d_%U.bckp’;

Next, create a standby controlfile backup via RMAN:
RMAN> configure channel device type disk format ‘/u01/app/oracle/backup/%U’;

new RMAN configuration parameters:
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT ‘/u01/app/oracle/backup/%U’;
new RMAN configuration parameters are successfully stored
released channel: ORA_DISK_1

RMAN> BACKUP CURRENT CONTROLFILE FOR STANDBY;

RMAN> BACKUP ARCHIVELOG ALL;

In this simple example, We are backing up the primary database to disk; therefore,we must make the backupsets available to the standby host if we want to use them as the basis for my duplicate operation:
[oracle@raclinux2 ~]$ cd /u01/app/oracle/backup
[oracle@raclinux2 backup]$ ls -lart

NOTE:

The primary and standby database location for backup folder must be same.

for eg: /u01/app/oracle/backup folder

On the standby node create the required directories to get the datafiles

mkdir -p /u01/app/oracle/oradata/10gsb
mkdir -p /u01/app/oracle/oradata/10gsb/arch
mkdir -p /u01/app/oracle/admin/10gsb
mkdir -p /u01/app/oracle/admin/10gsb/adump
mkdir -p /u01/app/oracle/admin/10gsb/bdump

mkdir -p /u01/app/oracle/flash_recovery_area/10GPRI
mkdir -p /u01/app/oracle/flash_recovery_area/10GPRI/onlinelogPrepare an Initialization Parameter File for the Standby Database

[oracle@raclinux2 ~]$ cd /u01/app/oracle/product/10.2.0/db_1/dbs/
