Restoring IM and IM Database Nodes

Use the following procedure to recover from IM failures.

• Instance Manager database node

  If the IM database node fails, restore the node from the latest backup.

• Instance Manager node

  If the IM node fails:

1. Set up a new IM node as described in the Cloud Infrastructure Deployment Guide.

2. Copy the following files to the new IM node:

   • /usr/local/share/PACI-im/IM-config.xml
   • /usr/local/share/PACI-im/system.properties
   • /usr/local/share/PACI-im/vm2vf/vm2vf-daemon.properties

   You back up these files as part of your disaster recovery plan. See Backing Up IM and IM Database Nodes for details.

3. Log in to the CloudBlue Commerce MN.

4. Configure the CloudBlue Commerce MN to communicate with the new IM node. To do this, run the following commands on the MN:

   # su - postgres
   $ psql plesk
   plesk=# update c2u_settings set value='http://New_IM_Node_IP:4465/paci/v1.0' where name='c2u.im.server.uri';
   plesk=# \q
   $ exit
   # service pa-agent restart

   where New_IM_Node_IP is the IP address or host name of the new IM node.
