Nokia 9.2 manual Testing the High Availability Features

Setting Up Database Mirroring

The following command line specifies the dbsrv10 options:

„-x—instructs the database server to use TCP/IP communications over port 2639. The other servers also use TCP/IP, but communicate on different ports.

„-su—specifies the password for the utility database.

„-n—names the database server Arbiter.

„-xa—specifies the names of the mirrored databases and the authentication string (in this case abc) for Arbiter server. This authentication string must be used on all the servers (Arbiter, Primary, and Mirror) in a database mirroring system.

„-xf—specifies the location of the state information file for Arbiter.

8.Start the Nokia Intellisync server on the server 1 computer by using the following bash script.

#!/bin/bash

source /opt/ims/conf/ims_profile

source /opt/ims/db/linux/bin/sa_config.sh

dbsrv10 -n server1 -x tcpip\(PORT=2638\) -xf /opt/ims/log/ server1state.txt -su admin /opt/ims/db/data/SyncDB.db -sn ha_server -xp partner="(ENG=server2;LINKS=tcpip(port=2637;TIMEOUT=1));auth=dba;ar biter=(ENG=arbiter;LINKS=tcpip(PORT=2639;TIMEOUT=1));mode=sync"

9.Start the mirror server on server 2 using the following bash script.

#!/bin/bash

source /opt/ims/conf/ims_profile

source /opt/ims/db/linux/bin/sa_config.sh

dbsrv10 -n server2 -x tcpip\(PORT=2637\) -xf /opt/ims/log/ server2state.txt -su admin /opt/ims/db/data/SyncDB.db -sn ha_server -xp partner="(ENG=server1;LINKS=tcpip(PORT=2638;TIMEOUT=1));auth=dba;ar biter=(ENG=arbiter;LINKS=tcpip(PORT=2639;TIMEOUT=1));mode=sync"

10.From the Nokia Intellisync server, open the /opt/ims/conf/config.properties file and set the following database URL:

url=jdbc:ianywhere:driver=libdbodbc10_r.so;DatabaseName=SyncDB;Isol ationLevel=1;ENG=ha_server;LINKS=tcpip

11.Start Nokia Intellisync Wireless Email.

Testing the High Availability Features

To test availability, stop all processes on either server 1, server 2, or the Arbiter server. Nokia Intellisync Wireless Email should continue working without any interruption in accessing the database.
