Sun Cluster 3.1 Data Service for SAP liveCache

How to Prepare the Nodes

Use this procedure to prepare for the installation and configuration of liveCache.

  1. Become superuser on all of the nodes.

  2. Configure the /etc/nsswitch.conf file.

    1. On each node that can master the liveCache resource, include one of the following entries for group, project, an passwd database entries in the /etc/nsswitch.conf file.


      database:
      database: files 
      database: files [NOTFOUND=return] nis
      database: files [NOTFOUND=return] nisplus
    2. On each node that can master the liveCache resource, ensure that files appears first for the protocols database entry in the /etc/nsswitch.conf file.

      Example:


      protocols: files nis

    Sun Cluster HA for SAP liveCache uses the su - user command and the dbmcli command to start and stop liveCache.

    The network information name service might become unavailable when a cluster node's public network fails. Implementing the preceding changes to the /etc/nsswitch.conf file ensures that the su(1M) command and the dbmcli command do not refer to the NIS/NIS+ name services.
