What's New?

Monitoring System Replication with the SAP HANA cockpit

The System Replication tile in the SAP HANA cockpit now displays the operation mode, together with replication mode, tiers and status.

The overview page of the System Replication app displays (configurable) information for both primary and secondary sites, a performance graph with network statistics and a tile for Alerts, that links back to the Alerts app in the SAP HANA cockpit. From the status bar, the Log File Viewer can be opened.

The System Replication Details view displays information on the operation mode, the replayed log position, as well as the replayed log position time.

In a system replication scenario, the SAP HANA Cockpit for Offline Administration can be used to perform a takeover from the primary side by the secondary site.

System Replication Alerts

A new alert (#94 - Log replay backlog for system replication secondary) is raised when the system replication log replay backlog is increased. Thresholds and schedule are configurable.

Monitoring System Parameter Changes

The configuration parameter checker reports on any differences between primary, secondary, and - new for SPS 12 - tier-3 secondary systems. Also new with SPS 12 is that you can now replicate the system (or .ini file) parameters based on alerts. The parameter replication can be enabled to all sites.


enable = true

replicate = true

Initializing the Secondary

Apart from using a full data backup, it is now possible to initialize the secondary system using a binary storage copy, that is, either a snapshot or a full offline database copy.

Alerting of Secondary Systems

The Alerts app of the SAP HANA cockpit now also displays alerts issued by secondary system hosts.

Supported Replication Modes Between Sites

In a multitier system replication scenario, support for ASYNC replication has been extended with both SYNCMEM and SYNC. In other words, all replication modes are supported for all sites.
