# IBM DB2 Database Backups

### Overview:

The IBM DB2 module is installed via the Commvault console after the Commvault File System Agent is installed and configured. If the servers are configured in a cluster, please note the details about the configuration in the SMC ticket that corresponds with this work effort.

#### Version & Requirements:

[http://documentation.commvault.com/commvault/v11/article?p=2893_2.htm](http://documentation.commvault.com/commvault/v11/article?p=2893_2.htm)

### System Requirements - IBM DB2 iDataAgent

#### Security & Permissions:

Expedient requires a DB2 user with SYSADM, SYSCTRL, or SYSMAINT and DBADM privileges to run backup and restore operations.

**Disk Space:**

- 2 GB minimum disk space is required for software installation.
- 256 MB is required for the job result directory.
- 256 MB is required for the log directory.

**Data Set:**

Backups include the following data:

NOTE: The Commvault File System Agent will be leveraged to back up the DB2 application files that are associated with the DB2 installation.

- DB2 database objects
- DB2 history files
- DB2 archive log files

#### Special Considerations:

The following paths must be manually created on the server prior to the Commvault DB2 module installation:

NOTE: If the DB2 Instance is clustered, these directories must be created on a shared disk; otherwise, they can be created on any disk with sufficient free space.

```plaintext
\Commvault_Backups\Audit_Error
\Commvault_Backups\Logs
\Commvault_Backups\Retrieve
```

The following DB2 parameters must updated for Expedient to configure and protect the DB2 database(s) with Commvault:

- LOGARCHMETH1

Use this parameter to specify the Commvault library that will be used to archive and manage the DB2 database log files.
- LOGARCHOPT1

Use this parameter to enable the DB2 to communicate with Commvault storage system during the Log archive and retrieve operations.
- VENDOROPT – vendor

Use this parameter to enable the DB2 to communicate with Commvault storage system during backup, restore, or load copy operations.
- TRACKMOD

Enable this parameter to allow the incremental/delta backups.

In order for Commvault to load its Media Library for Data Protection, the DB2 instance must be restarted post Commvault DB2 module installation.
