Install 18c Grid Infrastructure in Silent Mode

From Oracle 12.2 onwards, installation and configuration of Grid Infrastructure is done using gridSetup.sh.

Follow the following steps to install a 2-node 18c Grid Infrastructure cluster on Linux environment:

1. Download the software

2. Copy the software on first node

2. Unzip the software

3. Run gridSetup.sh


1. Download the software

Download 18.3 Grid Infrastructure from OTN website at https://www.oracle.com/technetwork/database/enterprise-edition/downloads/oracle18c-linux-180000-5022980.html

2. Copy the software on first node

Copy the 18.3 GI software onto the first node of the cluster

3. Unzip the software 

Unzip the 18.3 GI software at the installation directory on the first node of the cluster using below command:

unzip -d /u01/app/18.3.0/grid <path to zip file>

4. Run gridSetup.sh

Create the default responsefile under /u01/app/18.3.0/grid/response directory based on the required cluster configuration such as Scan name, Private, Public interface names and IP addresses etc.

/u01/app/18.3.0/grid/gridSetup.sh -silent -responsefile /u01/app/18.3.0/grid/response/response_file.rsp

When prompted, run root.sh as root user on all nodes starting from 1st:

/u01/app/18.3.0/grid/root.sh

Run the following command to configure tools on the 1st node:

/u01/app/18.3.0/grid/gridSetup.sh -silent -executeConfigTools -responsefile /u01/app/18.3.0/grid/response/response_file.rsp

ERROR OGG-00446 Unable to lock file while starting Goldengate extract

The Golden gate is installed on a 2-node RAC cluster and registered with Oracle clusterware through Bundle Agent.


On starting the goldengate gg_1 on 1st node, the Goldengate logfile ggserr.log shows following error:

Delete obsolete backups with RMAN in Oracle 11g

The RMAN retention policy specifies how many copies of backup we need to retain, By default, the value is 1.
Setting this parameter to 2 ensures that the latest two copies of datafile or tablespace backups is retained.

Check the retention policy of database

RMAN> show retention policy;

using target database control file instead of recovery catalog
RMAN configuration parameters for database with db_unique_name TESTDB are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default

Take the backup of tablespace or database twice. In this case we will take tablespace backup

Backup database plus archivelog using RMAN in oracle

When one use the backup database plus archivelog command to back up archive logs, RMAN will perform the following operations in the sequence listed here:

•  Run the "alter system archive log current" command.
•  Run the "backup archivelog all" command.
•  Back up the rest of the data files specified by the backup database command.
•  Run the "alter system archive log current" command.
•  Back up the new archive logs generated during the backup operation.
