DR Site - Dataguard - Virtual Hostname - Recommendation

[former_member340552]

Hello SAP Gurus,

We have installed the below HA System in our Primary Site. 

We have same SID for SAP & DB. Due to HA, we used Virtual-Host-name/IP in our Primary Site.

Now we are in process of setting up our DR Site.

•   We planned to use the Virtual-Hostname/IP in DR.
•   We planned to use Oracle-Data-guard for DB Replication at DR Site

Our environment

OS     : Solaris 10

DB     : Oracle 11.2

SAP   : NW7.0 / ECC 6.0 Ehp3 (Abap+Java)

Host-entry of Primary Server

erpph01 10.1.1.10      #Physical Host

erpdb      10.1.1.83        # DB Instance

erpd00    10.1.1.80       # PAS

erpscs     10.1.1.81        # Java CI

erpascs   10.1.1.84        # ABAP CI

Planned Host-entry for DR Server:

erpdr01   10.2.1.10      #Physical Host

erpdb      10.2.1.83      #DB Instance

erpd00    10.2.1.80      #CI+PAS

We got below queries:

1. Can we use the same virtual host-name for SAP & DB in DR Server?
2. How to up the DR Host in the fastest way without changing manually the ip address, host name in  ABAP &JAVA parameter files, Instance Profiles ?
3. How we can synchronize from Production Site SAP Application files (Instance profiles, Java configuration files, binary files..) to Disaster Recovery Site?   

Thanks for your feedback.

Hi,

You can check the below documentations about Standby Database and Data Guard configuration in SAP environment:

Hi Biborka,

Yes we already refered the attached documents and configured the Data-guard in our Testing Environment.

Since our production environment is in HA, we got below queries which is not clear in documents

1.Can we use the same virtual host-name for SAP & DB in DR Server?

2.How to up the DR Host in the fastest way without changing manually the ip address, host name in  ABAP &JAVA parameter files, Instance Profiles ?

3.How we can synchronize from Production Site SAP Application files (Instance profiles, Java configuration files, binary files..) to Disaster Recovery Site?

Thanks for your valuable feedback.

Hi Thahir,

1. Can we use the same virtual host-name for SAP & DB in DR Server?

In case of a DR you can change the IP behine the virtual name to DR servers. So in normal case virtual name will be point to primary servers and in case of DR, these virtual name will be pointing to DR servers.

2. How to up the DR Host in the fastest way without changing manually the ip address, host name in  ABAP &JAVA parameter files, Instance Profiles ?

If you are using Virtual name in the sap configuration then you only need to change IP behind the virtual name at network end. No change at configuration level required amnd SAP should start fine.

3.How we can synchronize from Production Site SAP Application files (Instance profiles, Java configuration files, binary files..) to Disaster Recovery Site?

You can use snapshot backup of primary server and apply them on DR site on regular basis.

There are other third party tools also available, which can help you achive thos e.g Libelle.
