Before Upgrading DSE OpsCenter

For any major release, review the changes in features, configuration files, metrics, and APIs impacting upgrades to OpsCenter.

DataStax strongly recommends upgrading to the most recent version of OpsCenter 6.8 for DSE 6.8, and DSE 5.1. Upgrading to this version ensures that you take advantage of new and improved features, enhanced performance, and fixed bugs or known issues.

OpsCenter versions 6.8.0 through 6.8.3 do not support DSE 5.1.x. Support for DSE 5.1.x is available in OpsCenter 6.8.4 and later.

See New features (6.8) for a description of features added in each OpsCenter release. See also OpsCenter compatibility with DSE.

Upgrade Considerations

Before upgrading to OpsCenter, carefully consider the following changes and follow any prescribed actions.

Support for Multiple User Roles using LDAP Authentication

Users can have multiple roles when using LDAP authentication. If the list of a user’s groups map to more than one role in OpsCenter, each user is granted each of the listed roles, and their resulting OpsCenter permissions are merged for all of their roles. See Adding a role for an LDAP user (6.8).

In OpsCenter 6.1.10 and later and OpsCenter 6.5.3 and later, you must update custom scripts and applications that use the OpsCenter API when using multiple user roles with LDAP authentication. If a custom script or application that uses the OpsCenter API did not account for multiple user roles, and a user has multiple roles, the script or application will fail because the role attribute cannot be found. The single role attribute is provided for users that have only one role. If your application or script has users with only one role, then updates are not required for continued use.

LCM Now Installs OpenJDK as the Default Option

Starting in January 2019, Oracle is ending public updates for the Oracle Java 8 runtime, requiring commercial users to purchase a paid license to obtain updates.

To simplify licensing, LCM in OpsCenter 6.7.0 introduces support for installing OpenJDK as the default option. LCM installs OpenJDK as distributed by operating system vendors through .deb or .rpm packages. Existing clusters are migrated to OpenJDK unless Oracle is explicitly selected as the Java vendor prior to running the first install or upgrade job from within OpsCenter 6.7.0.

To understand how this change effects your OpsCenter installation, see Choosing a Java vendor in Lifecycle Manager (6.8).
