$su - oracle

$mkdir -p /u01/app/oracle/product/19.0.0.0/dbhome_1

$mkdir -p /u01/patches/

 

 

#unzip /u01/patches/V982063-01.zip -d /u01/app/oracle/product/19.0.0.0/dbhome_1

#cd /u01/app/oracle/product/19.0.0.0/

#chown -R oracle:oinstall dbhome_1

 

$cd /u01/app/oracle/product/19.0.0.0/dbhome_1

$./runInstaller

 

 














[root@oraclelab1 ~]# /u01/app/oraInventory/orainstRoot.sh

Changing permissions of /u01/app/oraInventory.

Adding read,write permissions for group.

Removing read,write,execute permissions for world.

 

Changing groupname of /u01/app/oraInventory to oinstall.

The execution of the script is complete.

[root@oraclelab1 ~]#

[root@oraclelab1 ~]# /u01/app/oracle/product/19.0.0.0/dbhome_1/root.sh

Performing root user operation.

 

The following environment variables are set as:

    ORACLE_OWNER= oracle

    ORACLE_HOME=  /u01/app/oracle/product/19.0.0.0/dbhome_1

 

Enter the full pathname of the local bin directory: [/usr/local/bin]:

   Copying dbhome to /usr/local/bin ...

   Copying oraenv to /usr/local/bin ...

   Copying coraenv to /usr/local/bin ...


Creating /etc/oratab file...

Entries will be added to the /etc/oratab file as needed by

Database Configuration Assistant when a database is created

Finished running generic part of root script.

Now product-specific root actions will be performed.

Oracle Trace File Analyzer (TFA - Standalone Mode) is available at :

    /u01/app/oracle/product/19.0.0.0/dbhome_1/bin/tfactl

 

Note :

1. tfactl will use TFA Service if that service is running and user has been granted access

2. tfactl will configure TFA Standalone Mode only if user has no access to TFA Service or TFA is not installed

 

[root@oraclelab1 ~]#

 



  

Database creation Using DBCA utility

 

[oracle@oraclelab1 bin]$ pwd

/u01/app/oracle/product/19.0.0.0/dbhome_1/bin

[oracle@oraclelab1 bin]$ ls -ltr dbca

-rwxr-x---. 1 oracle oinstall 7749 Jul  8 21:30 dbca

[oracle@oraclelab1 bin]$ ./dbca

 



 

Here I create Normal database

 

Global database name we need to give our DB name

 

Global database name: DEVDB

Sys password: Manager@123

 

 



 


 


 

 

 DB creation Completed.

 

SQL> select name,created,open_mode,log_mode from v$database;

Once asked above questions to development team in meanwhile we need to start basic sanity check in our environment. 1 Verify the status of the concurrent program select REQUEST_ID,phase_code,status_code,ORACLE_SESSION_ID from apps.fnd_concurrent_requests where request_id=’1234567’; 2 Find which concurrent manger ran a specific concurrent request select b.USER_CONCURR
