Detailed System Requirements
Abstract
This document details the backup and restores requirements for InterSystems Database for IBM Storage Defender Copy Data Management 2.3.1.
Content
📋 Quick Navigation
General
- IBM Storage Defender Copy Data Management installs an agent on application servers when they are registered.
For AIX-based systems, the agent installation directory must be excluded for any anti-virus software scans. Add this path to the exclusion list for all anti-virus software that is installed on the application server.
/tmp/cdm_guestapps_<username>Where <username> is the username of the account used to register the application server in IBM Storage Defender Copy Data Management.
- IBM Storage Defender Copy Data Management support for third-party operating systems, applications, services, and hardware depend on the respective vendor. If a third-party product or version moves into extended support, self-service support, or end-of-life, IBM Storage Defender Copy Data Management supports the product or version at the same level as the vendor.

Notes
- With CDM 2.3.1 relase, Db2 database standalone configurations are supported only.
- Cluster Db2 solutions are not supported.
- Virtual mode of configuration/registration is not supported for Db2
- Only snapshots of the storage provider type ‘IBM storage virtualize for snapshot’ is supported.
- Db2 archive log mode is not supported. It is recommended to configure Db2 in no archive log mode at present
- Instant database restore for Db2 is not supported for this release.
- PIT restore is not supported
- Database Revert is not supported for DB2
Replication mode is not supported. It includes policy-based replication.
Connectivity
- The SSH service must be running on port 22 on the server and any firewalls must be configured to allow IBM Storage Defender Copy Data Management to connect to the server by using SSH. The SFTP subsystem for SSH must also be enabled.
- The server can be registered by using a DNS name or IP address. DNS names must be resolvable by IBM Storage Defender Copy Data Management.
- To mount clones or copies of data, IBM Storage Defender Copy Data Management automatically maps and un-maps LUNs to the servers. Each server must be preconfigured to connect to the relevant Storage Systems at that site.
- For Fibre Channel, the appropriate zoning must be configured beforehand.
Prerequisites
On DB2 Server
1. DB2 Installation
DB2 must be installed and configured
DB2 instance(s) must be created
DB2 instance must be started before discovery/backup operations
Start DB2 instance
Verify instance is running
sudo -u db2inst1 db2 get instance
2. Environment Variables
- DB2DIR environment variable must be set (e.g., /opt/ibm/db2/V12.1) where V12.1
is the DB2 version. Users can set it as per DB2 version they have.
- Setting DB2DIR Environment Variable
The DB2DIR environment variable should point to the DB2 installation directory:
For DB2 12.1
export DB2DIR=/opt/ibm/db2/V12.1
Add to system-wide profile
echo "export DB2DIR=/opt/ibm/db2/V12.1" >> /etc/profile.d/db2.sh
Verify DB2DIR is set correctly:
bash
echo $DB2DIR
ls -la $DB2DIR/instance/db2ilist
- Alternative: DB2 profile at `$HOME/sqllib/db2profile` for current user
- Supports both default and non-default installation paths via `DB2DIR`
3. Python 3.x
- Python 3.6 or higher required
- No additional Python packages needed (uses native DB2 CLI)
4. Sudo Configuration
- The IBM Storage Defender Copy Data Management agent user needs the following privileges:
- Privileges to run commands as root and other users by using Sudo. IBM Storage Defender Copy Data Management requires these privileges for various tasks such as discovering storage layouts and mounting and unmounting disks.
The sudoers configuration must allow the IBM Storage Defender Copy Data Management agent user to run commands without a password.
The! requiretty setting must be set.
Place the following lines at the end of your sudoers configuration file, typically /etc/sudoers.
cdmagent ALL=(ALL) NOPASSWD: ALL
Defaults:cdmagent !requiretty
Defaults:cdmagent env_keep+="DB2INSTANCE"
Defaults:cdmagent env_keep+="DB2_HOME"
Defaults:cdmagent env_keep+="INSTHOME"
5. DB2 CLI Access
- db2 command must be in PATH or accessible via instance profile
- db2ilist command must be available for instance discovery
- Database manager must be started (see requirement #1)
6. File System Permissions
- Read access to DB2 instance home directories (e.g., `/home/db2inst1`)
- Read access to DB2 configuration files
- Read access to database storage paths
