This document outlines the upgrade process of SAP HANA 2 SPS02, including the installation of dynamic tiering, with a focus on utilizing a near-zero downtime approach. It explains the changes in system replication capabilities with dynamic tiering and provides detailed steps for upgrading both primary and secondary databases. Additionally, it discusses the monitoring of HANA systems using the IT-Conductor tool, which automatically detects new services post-implementation.

3. Introduction (1)
In previous work, HANA 1.0 SPS12 was upgraded to HANA 2 SPS00 –
presented in the following document
‘Manager and Monitoring SAP HANA2 Active:Active System Replication’
In that exercise, we explored new features of HANA 2 SPS00, such as
system replication – the ‘active:active read-enabled, allowing read-only
queries on secondary system’s tables using the new operation mode
‘logreplay_readaccess’
Dynamic tiering was not included in that upgrade due to restriction of not
being able to use logreplay_readaccess if dynamic tiering is
installed/implemented.

4. Introduction (2)
In this exercise, the following steps were performed
• Upgrade of both primary and secondary databases to SPS02,
using ‘Near Zero Downtime Upgrade’ option
• Upgrade of HANA cockpit
• Installation and data provisioning of Dynamic Tiering (SPS02)

26. Dynamic Tiering (1)
In the previous HANA2 SPS00 setup, read-enabled active:active secondary
system was active, but dynamic tiering was not configured due to
restriction.
With SPS02, dynamic tiering is now allowed with the read-enabled
active:active secondary system.
Extract from the Administration Guide
•SP 00 and 01: If dynamic tiering is part of the landscape, the site does not allow active/active
support, even for SAP HANA services.
•SP 02: (Changed) If active/active (read enabled) is used with dynamic tiering services, there
is no read access to dynamic tiering data on the secondary site. When dynamic tiering is part
of landscape, active RO access is allowed using operation mode logreplay_readaccess on
other HANA services (IS) but without dynamic tiering access. (A query that accesses data on
secondary dynamic tiering returns an error.)

the administration guide.
IT-Conductor monitoring tool:
- Automatically ‘discovers’ the new service ‘esserver’ after the
dynamic tiering installation/implementation
- Both primary and secondary databases (SYSTEMDB and
