What is Deprecation of Non-CDB Architecture means

Please check the below link for point (8.1.1 : Deprecation of Non-CDB Architecture).

https://docs.oracle.com/database/121/UPGRD/deprecated.htm#BABDBCJI

"Deprecation" means "at some stage in future, Oracle might stop doing enhancements on this features, and at some stage after that, Oracle might no longer support it".

In 12.1.0.1.0 non-CDB (old architecture) is not deprecated whereas from 12.1.0.2.0 it got deprecated. Even if you have single database, it is better to have it in multitenant architecture as 1CDB and 1PDB.

As per Oracle document:- https://docs.oracle.com/en/database/oracle/oracle-database/12.2/upgrd/deprecated-features-oracle-database-12c-r2.html#GUID-5D181F03-F74D-4888-B7B2-7176CF6FA8F8

Deprecation of Non-CDB Architecture

The non-CDB architecture was deprecated in Oracle Database 12c. It can be desupported and unavailable in a release after Oracle Database 19c .

Oracle recommends use of the CDB architecture.

Oracle Database 19c ?

Release 12.2: New releases will be annual and the version will be the last two digits of the release year. The release originally planned as 12.2.0.2 will now be release 18c, and the release originally planned as 12.2.0.3 will be release 19c. Releases 18c and 19c will be treated as under the umbrella of 12.2 for Lifetime Support purposes. The current plan is for Oracle Database 19c to be the last release for 12.2. This may change in the future to Oracle 20 as the last release for 12.2

DBA_SCHEDULER_JOB_RUN_DETAILS and PURGE_LOG

How to purge DBA_SCHEDULER_JOB_RUN_DETAILS? Manually deleting from DBA_SCHEDULER_JOB_RUN_DETAILS is not recommended by oracle.DBA_SCHEDULER_JOB_RUN_DETAILS is a view that is using two master tables (scheduler$_job_run_details and scheduler$_event_log) and display the information about jobs history. As there is one procedure named PURGE_LOG and Oracle have Scheduler for this procedure. It will purges all rows in the job log that are older than 30 days.This is the default behavior of this procedure. You can change this to any number of days you want by setting the attribute "SET_SCHEDULER_ATTRIBUTE". e.g. exec DBMS_SCHEDULER.SET_SCHEDULER_ATTRIBUTE('log_history','15'); It will purge all logs older than 15days and it will maintain the history of 15days. But If you want manually purge these logs, you can use below solution:- exec DBMS_SCHEDULER.PURGE_LOG(log_history => 15, which_log => 'JOB_LOG'); It will purge all entries from the jog log that are o...

Oracle character AL32UTF8

The character set determines what languages can be represented in the database. Oracle recommends using Unicode (AL32UTF8) as the database character set. AL32UTF8 is Oracle's name for the UTF-8 encoding of the Unicode standard. The Unicode standard is the universal character set that supports most of the currently spoken languages of the world. The use of the Unicode standard is indispensable for any multilingual technology, including database processing. Changing the database character set is a time consuming and complex project. Therefore, it is very important to select the right character set at installation time. If the language is American English or a Western European language, then the default character set is WE8MSWIN1252. Each Microsoft Windows ANSI Code Page can store data from only one language or a limited group of languages, such as only Western European, or only Eastern European, or only Japanese. AL32UTF8 is a multibyte character set, database operations on character...

ORA-02291: integrity constraint violated - parent key not found

“Error: ORA-02291: integrity constraint violated - parent key not found” Reason: A Primary key does not have the same value as the foreign key. We will discuss it in detail later in this article. Action: For ORA-02291: integrity constraint violated - parent key not found You may either delete the foreign key or the matching primary key can be added. In either way, you may try to get this error corrected. Let's understand more about ORA-02291: integrity constraint violated - parent key not found? The Oracle software brought us the strength by which multiple tables in the database can pass on information so efficiently. Not only this, there are numerous devices in this software which enables access to and sourcing data from multiple tables. You can easily execute complicated database issues without an unusual uncertainty by creating statements with the fantastic characteristic of this software. Realistically, if we talk about user or database no one is perf...
