Changing the password of the WebSphere Liberty keystore
You can change the password of the IBM® WebSphere® Liberty keystore.
Changing the keystore that is used by WebSphere Liberty
When you install IBM OpenPages with Watson, the installation process configures a keystore for IBM WebSphere Liberty. If you have an existing keystore or if you want to use an alternate keystore, you can change the keystore that is used by WebSphere Liberty. This task is optional.
Changing the keystore that is used by Db2
When you install IBM OpenPages with Watson, the installation process configures a keystore for IBM WebSphere Liberty. By default, the Liberty keystore is also used for Db2®. If you have an existing keystore or if you want to use an alternate keystore, you can change the keystore that is used by Db2. This task is optional.
Changing the OPSystem password
You can change the password of the OPSystem account. OPSystem is a default service user account that is required by internal system actions.

If the password of the OpenPages database changes, you need to update password references with the new password.
Changing database name references
If the database name (IBM Db2) or identifier (Oracle) changes, you need to update references to the database.
TLS for OpenPages with Watson environments
You can configure OpenPages with Watson to use Transport Layer Security (TLS).
Db2 native encryption
OpenPages with Watson supports Db2 native encryption.
Oracle Transparent Data Encryption (TDE)
You can use Oracle Transparent Data Encryption (TDE) to encrypt the OpenPages and Cognos® table spaces in the OpenPages database.
Shortening the URL for OpenPages with Watson
You can shorten the IBM OpenPages with Watson application URL. You might shorten the URL to support privacy or to support some mobile uses of the URL. To shorten the URL, change the values for properties in various files.
Parameters for cluster members
When working with cluster members, there are values for common parameters. You must enter these parameter values consistently across all of the tasks.
Configuring HTTP compression in OpenPages with Watson
HTTP compression is a technique used to reduce the network bandwidth that is used to transfer files from the server to the client by compressing web content. Compliant web browsers automatically decompress the content before displaying it to users.
