Intro

OCI (Oracle Cloud Infrastructure) provides robust automation capabilities for routine maintenance tasks such as patching, creating database homes, and server OS updates. Oracle further simplifies these tasks by handling the staging process, reducing the administrative burden.

Additionally, Oracle has introduced several tools to streamline maintenance and management tasks, including:

dbaascli

exacli

dbcli

exadbcpatchmulti

dbaascli is a command-line utility for managing Oracle Database Cloud Services (DBaaS) instances. Mainly for Oracle Exadata cloud services. It provides several features to administer Oracle databases running on Oracle Cloud Infrastructure (OCI). This tool allows users to perform various administrative tasks like backup and recovery, patching, scaling, and checking the status of the database environment.

Key Features of dbaascli:

Backup and Restore:
- Manage and schedule backups.
- Perform on-demand backups.
- Restore the database from backups.
Patching:
- Apply database patches.
- Check for available patches.
- Rollback patches if necessary.
Database Management:
- Start and stop databases.
- Perform database health checks.
- Manage Data Guard configurations (for high availability and disaster recovery).
Storage Management:
- Resize the database storage as required.
Diagnostic Tools:

Collect diagnostic information to troubleshoot issues.
Generate diagnostic logs for support cases.

As a DBA, it's essential to start utilizing these orchestration tools to streamline and simplify your tasks. These tools make database management more efficient by automating key processes. With dbaascli, for example, DBAs no longer need to manually download and copy binary files to servers—dbaascli will automatically download the latest binaries, making the entire process faster and smoother.

In this article, I will demonstrate how to create a database using dbaascli.

Note: Creating a non-CDB database is not supported via the console. The only way to create a non-CDB database is through the backend.

Step 1: Identify the Database Home

First, identify and note down the Database Home associated with the version you want to use for creating the database.

For this example, since I want to create a database using the 19c home, I will record the path for the 19c Database Home.



[root@exadevdb-node01 ~]# dbaascli dbhome info
DBAAS CLI version 24.3.2.0.0
Executing command dbhome info
[INFO] [DBAAS-14011] - The usage of this command is deprecated.
   ACTION: It is recommended to use 'dbaascli dbHome getDetails or dbaascli system getDBHomes' for this operation.
Enter a homename or just press enter if you want details of all homes

1.HOME_NAME=OraHome1
  HOME_LOC=/u02/app/oracle/product/19.0.0.0/dbhome_1
  VERSION=19.24.0.0
  PATCH_LEVEL=19.24.0.0.0
  DBs installed=
   OH Backup=NOT Configured

2.HOME_NAME=OraHome3
  HOME_LOC=/u02/app/oracle/product/11.2.0/dbhome_1
  VERSION=11.2.0.4
  PATCH_LEVEL=11.2.0.4.231017
  DBs installed=TEST
   Agent DB IDs=ec3f0396-d79d-450f-a9b3-aaae88b37c56
 OH Backup=NOT Configured

[root@exadevdb-node01 ~]#

To retrieve the DB home information, you can use the latest dbaascli command:


dbaascli system getDBHomes

This output will be a Jason output

Create a database using dbaascli commands

Here is a sample command to create the database. For detailed information, refer to the Oracle documentation at: Using dbaascli for Exadata Database Service

Since we are creating a non-container database, the createAsCDB parameter is set to false.



/bin/dbaascli database create \
--dbname SYNPOC \
--dbUniqueName SYNPOC_EXA \
--dbSID SYNPOC1 \
--createAsCDB false \
--dbCharset AL32UTF8 \
--dbNCharset AL16UTF16 \

--pgaSizeInMB 1024 \
--oracleHome /u02/app/oracle/product/19.0.0.0/dbhome_1 \
--oracleHomeName OraHome1 \
--tdeConfigMethod FILE \
--executePrereqs no
