Changing the Encryption Key from the Command Line

After installation, you can change the encryption key for the domain from the command line. You must shut down the domain before you change the encryption key.

Use the infasetup command to generate an encryption key and configure the domain to use the new encryption key.

The following infasetup commands generate and change the encryption key:

generateEncryptionKey: Generates an encryption key in a file named sitekey. If the directory specified for the encryption key contains a file named sitekey, Informatica renames the file to siteKey_old.
migrateEncryptionKey: Changes the encryption key used to store sensitive data in the Informatica domain.

To change the encryption key for a domain, complete the following steps:

Shut down the domain.

Back up the domain before you change the encryption key.

To ensure that you can recover the domain if you encounter problems when you change the encryption key, back up the domain before you run the infasetup commands.

To generate an encryption key for the domain, run the

infasetup generateEncryptionKey

command.

Specify the

encryptionKeyLocation

option to generate an encryption key:

Option	Argument	Description
-encryptionKeyLocation -kl	encryption_key_location	Directory that contains the current encryption key. The name of the encryption file is `sitekey`. Informatica renames the current `sitekey` file to `sitekey_old` and generates an encryption key in a new file named `sitekey` in the same directory.

The installer creates an encryption key during installation and upgrade. You do not need the keyword and domain name options while generating the encryption file sitekey. Make sure that you save a copy of the unique site key. If you lose the site key, you cannot generate the site key again. Do not share the unique site key with others.

To change the encryption key for the domain, run the

infasetup migrateEncryptionKey

command and specify the location of the old and new encryption key.

Specify the following options required to change the encryption key for the domain:

Option	Argument	Description
-LocationOfEncryptionKeys -loc	location_of_encryption_keys	Directory in which the old encryption key file named `siteKey_old` and the new encryption key file named `siteKey` are stored. The directory must contain the old and new encryption key files. If the old and new encryption key files are stored in different directories, copy the encryption key files to the same directory. If the domain has multiple nodes, this directory must be accessible to any node in the domain where you run the migrateEncryptionKey command. When you migrate a multinode domain, all the nodes in the domain must use the same encryption key. To change the encryption key for the domain, run the infasetup migrateEncryptionKey command on all nodes in the domain. On UNIX, the file name `siteKey_old` is case-sensitive. If you manually rename the previous encryption key file, verify that the file name has the correct letter case.
-IsDomainMigrated -mig	is_domain_migrated	Indicates whether the domain has been updated to use the latest encryption key. When you run the migrateEncryptionKey command for the first time, set this option to False to indicate that the domain uses the old encryption key. After the first time, when you run the migrateEncryptionKey command to update other nodes in the domain, set this option to True to indicate that the domain has been updated to use the latest encryption key. Or, you can run the migrateEncryptionKey command without this option. Default is True.

Run the infasetup command on each node in the domain.

If the domain has multiple nodes, run infasetup migrateEncryptionKey on each node. Run the command on the gateway nodes before you run the command on the worker nodes. You can omit the IsDomainMigrated option after the first time you run the command.

Restart the domain.

You must upgrade all repository services in the domain to update and encrypt sensitive data in the repositories with the new encryption key. You must also migrate the site key after you upgrade the domain.

Upgrade all Model Repository Services, PowerCenter Repository Services, and Metadata Manager Services.

You can upgrade a Model Repository Service and a PowerCenter Repository Service in the Administrator tool or at the command prompt. You can upgrade a Metadata Manager Service in the Administrator tool.

The Metadata Manager Service must be disabled before you can upgrade it.

To upgrade a service in the Administrator tool, select

Manage

Upgrade

in the header area. If you select multiple services, the Administrator tool upgrades the services in the correct order.

To upgrade a service at the command prompt, use the following commands:

Repository Service Type	Command
Model Repository Service	infacmd mrs UpgradeContents
PowerCenter Repository Service	pmrep Upgrade
