OIM 12c: Schema Backup and Restoration using Data Pump Client Utility (Doc ID 2584066.1)

Last updated on AUGUST 31, 2023

Purpose

Overview

The Database Layer (OIM and its dependent Schemas) are an integral part of the OIM Application Infrastructure.

This document intends to provide for a step-by-step process in detail for the “Logical” Backup and Restoration of the OIM 12c Application Database Schemas using Oracle’s Data Pump utility.

What this Technical Note covers

1. Backup of OIM 12c and its dependent Schemas of a running deployment.

2. Restoration from scratch on a different¹/same database instance.

3. The methodology depicted is not intended for a Production level Backup Restoration and Recovery solution for an enterprise customer deployment.

¹ - a different instance on the same or on a different physical machine.

What this Technical Note does NOT cover

1. Backup/Restoration methodology for the OIM 12c Upgrade environments

2. Backup/Restoration methodology for T2P scenarios.

Oracle Identity Manager 12c Database Schemas

From the operational perspective, OIM 12c and its dependent Database Schemas topology consists of the following ELEVEN mandatory schemas:

1. Oracle Identity Manager (OIM) Schema [OIM 12c]

2. Meta Data Service (MDS) Schema

3. Service Oriented Architecture Infra (SOAINFRA) Schema

4. Oracle Platform Security Services (OPSS) Schema

5. Audit Service (IAU) Schema

6. Audit Service Append (IAU_APPEND) Schema

7. Audit Service Viewer (IAU_VIEWER) Schema

8. Service Table (STB) Schema

9. User Messaging Service (UCSUMS) Schema

10. WebLogic Services (WLS) Schema

11. WebLogic Services Runtime (WLS_RUNTIME) Schema

OIM 12c Database Backup and Restoration

Local Backup of OIM Schema

For the Logical Backup of OIM 12c Schemas (and its subsequent Restoration), the recommended tool is Oracle Data Pump Export Utility.

Restoration of OIM Schema

For the restoration of the Logical Backup (taken using the Oracle Data Pump Export utility), the corresponding utility i.e. the Data Pump Import utility is to be essentially used.

Following are the possible scenarios of restoration based on the location of restore:

1. Local restoration - Restoration in the “same” Database Instance post Schema drop

2. Remote restoration - Restoration in a “different” Database Instance

 Data Pump is a tool of choice over conventional export/import utility, as it not only provides a platform independent data dump but also by way of its architectural enhancements it is faster.

Data Pump command line clients are available out-of-the-box with Oracle Database Client/Server (Oracle DB 10g and onwards) with no additional licensing cost.

NOTE - Check for the compatibility of the Data Pump Client w.r.t. to the Target Database in use.

Compatibility between the DB version and the Data Pump Client:

A newer version of Data Pump Client cannot be used in order to export data from a lower database version.

For example to export data from database version 10.2.0.3 or 9.2 the 11.1.0.7 Data Pump Client would not suffice.

Remote vs Local Restoration

Steps for restoration on Local or Remote DB Instances are same almost the same except for:

1. In Remote Restoration, schemas are imported in a different database instance (which can be on a different machine as well). This Database may or may not have any prior OIM 12c Schemas or even any FMW Schema created on it, depending on this some additional steps may be required.

2. In the case of Remote DB restoration, the JDBC connection information is to be modified as per the steps in the section “OIM 12cmid-tier side JDBC Connection configuration”.

 Generic High Level Steps in Logical Export of OIM 12c Schemas

 NOTE - Order of Export of Database Schemas does not matter from the OIM 12c Application functionality perspective.

What to retain along with the exported data dump

 For ease of subsequent restoration, following details are to be retained for later reference along with the OIM export dump:

1. Name of the OIM/dependent Schemas

2. Default and Temporary Tablespace names of OIM and its dependent schemas, along with names of any other tablespaces involved in OIM/other Schema objects.

3. Data Pump/Conventional Export log file

Generic High Level Steps in Logical Import of OIM 12c Schemas

NOTE - Steps 2) and 4) can be skipped if restoring on the same DB Instance (using the same schema names).
