How to Install and Configure liveCache

Use this procedure to install and configure liveCache.

1. Install and configure SAP APO System.

   See Sun Cluster Data Service for SAP Guide for Solaris OS for the procedures on how to install and configure SAP APO System on Sun Cluster software.

2. Install liveCache.

   ---

   Note –

   Install liveCache by using the physical hostname if you have not already created the required logical host.

   ---

   For more information, see your SAP documentation.

3. If you are using liveCache 7.5 or compatible versions, ensure that the liveCache administrator user is in the sdba user group.

   The format of the liveCache administrator user's user ID is lc-nameadm.

   If you are creating the liveCache administrator user manually, add the following entry to the /etc/group file:

   sdba::group-id:lc-nameadm
   

   group-id

   The group's unique numerical ID (GID) within the system

   lc-name

   Lowercase name of liveCache database instance

   For more information about the /etc/group file, see the group(4) man page.

4. Become liveCache administrator user, create the .XUSER.62 file for the SAP APO administrator user and the liveCache administrator user by using the following command.

   ---

   Note –

   This user whose home directory contains the .XUSER.62 file is an internal database user who has permissions to start, stop, and query the database.

   ---

   $ dbmcli -uk username,passwd -d LC-NAME -n logical-hostname

   LC-NAME

   Uppercase name of liveCache database instance

   logical-hostname

   Logical hostname that is used with the liveCache resource

   ---

   Caution –

   Neither SAP APO transaction LC10 nor Sun Cluster HA for SAP liveCache functions properly if you do not create this file correctly.

   ---

5. Copy /usr/spool/sql from the node or zone, on which you installed liveCache, to all the nodes or zones that will run the liveCache resource. Ensure that the ownership of these files is the same on all node or zone as it is on the node or zone on which you installed liveCache.

   Example:

   # tar cfB - /usr/spool/sql | rsh destination tar xfB -

   destination

   Specifies the node or zone which you are copying the /usr/spool/sql directory and its contents

6. Copy the /etc/opt/sdb directory and its contents from the node or zone on which you installed liveCache, to all the nodes or zones where resources for liveCache will run. Ensure that the ownership of these files is the same on all nodes or zones as it is on the node or zone on which you installed liveCache.

   # tar cfB - /etc/opt/sdb | rsh destination tar xfB -

   destination

   Specifies the node or zone which you are copying the /etc/opt/sdb directory and its contents

7. Create a link from the /sapdb/LCA/db/wrk directory to the /sapdb/data/wrk directory as follows:

   # ln -s /sapdb/data/wrk /sapdb/LCA/db/wrk

8. Ensure that all the required system files have been copied from the install node or zone to all the nodes or zones that will run the liveCache resource. The required files include /etc/group and /etc/passwd.
