How To Replace Dbms_reputil.from_remote In Oracle 12.2.0.1 Since All Objects Removed Except REPLICATION_IS_ON, _OFF And _ON
Introduction
In Oracle 12c, the DBMS_REPUTIL package is used for replication purposes. However, in some cases, the objects related to this package might get removed, leaving only a few essential objects like REPLICATION_IS_ON, _OFF, and _ON. This article will guide you on how to replace DBMS_REPUTIL.FROM_REMOTE in Oracle 12.2.0.1 when all objects are removed except these three.
Understanding the Issue
When the objects related to DBMS_REPUTIL are removed, it can cause issues with replication. The FROM_REMOTE procedure is used to replicate data from a remote database. However, without the necessary objects, this procedure will fail. In this scenario, you need to recreate the missing objects to restore the functionality of DBMS_REPUTIL.
Recreating the Missing Objects
To recreate the missing objects, you need to execute the following SQL scripts:
Step 1: Recreate the DBMS_REPUTIL Package

**Q&A: How to Replace DBMS_REPUTIL.FROM_REMOTE in Oracle 12.2.0.1 Since All Objects Removed Except REPLICATION_IS_ON, _OFF and _ON**
===========================================================
**Q: What is DBMS_REPUTIL.FROM_REMOTE and why is it important?**
---------------------------------------------------------
A: DBMS_REPUTIL.FROM_REMOTE is a procedure in the DBMS_REPUTIL package that is used for replication purposes in Oracle 12c. It allows you to replicate data from a remote database. This procedure is essential for maintaining data consistency across multiple databases.
**Q: What happens if the objects related to DBMS_REPUTIL are removed?**
----------------------------------------------------------------
A: If the objects related to DBMS_REPUTIL are removed, the FROM_REMOTE procedure will fail. This can cause issues with replication and data consistency.
**Q: How can I recreate the missing objects?**
--------------------------------------------
A: To recreate the missing objects, you need to execute the SQL scripts provided in the previous section. These scripts will recreate the DBMS_REPUTIL package and its body, which includes the FROM_REMOTE procedure.
**Q: What are the benefits of recreating the missing objects?**
---------------------------------------------------------
A: Recreating the missing objects will restore the functionality of DBMS_REPUTIL, allowing you to replicate data from a remote database. This will ensure data consistency across multiple databases and prevent issues with replication.
**Q: Are there any potential risks or issues with recreating the missing objects?**
--------------------------------------------------------------------------------
A: Yes, there are potential risks and issues with recreating the missing objects. For example, if the recreated objects are not identical to the original objects, it may cause issues with replication or data consistency. Additionally, if the recreated objects are not properly configured, it may lead to performance issues or other problems.
**Q: How can I ensure that the recreated objects are identical to the original objects?**
-----------------------------------------------------------------------------------
A: To ensure that the recreated objects are identical to the original objects, you should carefully review the SQL scripts and make sure that they are accurate and complete. You should also test the recreated objects thoroughly to ensure that they are functioning correctly.
**Q: What are the system requirements for recreating the missing objects?**
-------------------------------------------------------------------------
A: The system requirements for recreating the missing objects are:
* Oracle 12c (12.2.0.1 or later)
* DBMS_REPUTIL package and its body
* SQL scripts to recreate the missing objects
**Q: Can I recreate the missing objects manually?**
------------------------------------------------
A: Yes, you can recreate the missing objects manually by creating the necessary tables, procedures, and other objects. However, this can be a complex and time-consuming process, and it may be easier to use the provided SQL scripts to recreate the missing objects.
**Q: What are the best practices for maintaining DBMS_REPUTIL and its objects?**
--------------------------------------------------------------------------------
A: The best practices for maintaining DBMS_REPUTIL and its objects are:
* Regularly back up the database and its objects
* Monitor the database and its objects for issues or errors
* Test the database and its objects regularly to ensure that they are functioning correctly
* Update the database and its objects as needed to ensure that they are compatible with the latest Oracle versions
By following these best practices, you can ensure that DBMS_REPUTIL and its objects are functioning correctly and that your database is running smoothly.
