SAP HANA 2.0 SPS 00 What’s New: High Availability

Introduction

we will be posting new videos to the SAP HANA Academy to show new features and functionality introduced with SAP HANA 2.0 Support Package Stack (SPS) 00.

What’s New?

SAP HANA Cockpit

In the previous blog post about system administration, we have already discussed the new SAP HANA cockpit 2.0. For system replication, all the core administration activities can now be performed using this tool. This includes:

• Registering primary and secondary systems
• Sytem replication monitoring 
• Take over and failback
• Disabling

 

Active/Active (Read Enabled)

Another great new system replication feature is the new Log Replay – Read Access operation mode, which enables read-only access on the secondary system.

 

This means that the secondary system can now conveniently be used for reporting purposes. For more information.

System PKI SSFS

With SAP HANA 2.0, system replication requires authentication for data and log shipping channels. For this, the certificates from the system PKI SSFS store are used. For the current release, automatic certificate copying is not yet integrated into the registration process for the secondary host and needs to be performed manually using file copy.

 

Using the secure copy command to copy the PKI SSFS store and key file from the primary to the secondary host:

# set the variables to match your environment
export RSECSSFS=/hana/shared/SHA/global/security/rsecssfs
export SIDADM=shaadm
export SECONDARY=mo-1caae8fcb.mo.sap.corp

# copy the system PKI SSFS store and key file from the primary to the secondary host
scp $RSECSSFS/data/SSFS_SHA.DAT $SIDADM@$SECONDARY:$RSECSSFS/data/
scp $RSECSSFS/key/SSFS_SHA.KEY $SIDADM@$SECONDARY:$RSECSSFS/key/
