## Installing and Configuring liveCache

This section contains the procedures that you need to install and configure liveCache.

## How to Install and Configure liveCache

Use this procedure to install and configure liveCache.

1. Install and configure SAP APO System.

   See Oracle Solaris Cluster Data Service for SAP Guide for the procedures on how to install and configure SAP APO System on Oracle Solaris 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. Ensure that the liveCache administrator user is in the `sdba` user group.

   The format of the liveCache administrator user's user ID is lc-name `adm`.

   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 -d   LC-NAME -n logical-hostname-ususername,passwd

   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 HA for SAP liveCache functions properly if you do not create this file correctly.

5. Copy `/usr/spool/sql` if it exists, from the node or zone, on which you installed liveCache, to all the nodes that will run the liveCache resource.

   Ensure that the ownership of these files is the same on all nodes as it is on the node or zone on which you installed liveCache.

   Example:

       # tar cfB /tmp/usr-spool.tar /usr/spool/sql
       Log in to the destination zone.
       # scp root@soruce:/tmp/usr-spool.tar /tmp
       # cd /
       # tar xfb /tmp/usr-spool.tar

   source

     Specifies the node or zone where you installed SAP liveCache

6. Copy the `/etc/opt/sdb` directory and its contents from the node 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 as it is on the node or zone on which you installed liveCache.

       # tar cfB /tmp/opt-sdb.tar /etc/opt/sdb
       Log in to the target zone.
       # scp root@source:/tmp/opt-sdb.tar /tmp
       # cd /
       # tar xfb /tmp/opt-sdb.tar

   source

     Specifies the node or zone where you installed SAP liveCache.

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`, `/etc/passwd`, `/etc/project`, and `/etc/user_attr`.

## How to Enable liveCache to Run in a Cluster

During a standard SAP installation, liveCache is installed with a physical hostname. You must modify liveCache to use a logical hostname so that liveCache works in a Oracle Solaris Cluster environment. Use this procedure to enable liveCache to run in a cluster.

Before You Begin

Ensure that the `/etc/netmasks` file has IP-address subnet and netmask entries for all logical hostnames. If necessary, edit the `/etc/netmasks` file to add any missing entries.

1. Create the failover resource group to hold the network and liveCache resource.

       # clresourcegroup create [-n node-zone-list] livecache-resource-group

2. Verify that you added all the network resources you use to your name service database.
3. Add a network resource (logical hostname) to the failover resource group.

       # clreslogicalhostname create -g livecache-resource-group \
       -h lc-logical-hostname lc-logical-hostname

   Note - If you require a fully qualified hostname, you must specify the fully qualified name with the `-h` option and you cannot use the fully qualified form in the resource name.

4. Enable the failover resource group.

       # clresourcegroup online -M livecache-resource-group

5. Enable the network resource (logical hostname).

       # clresource enable lc-logical-hostname

6. Log on to the node or zone that hosts the liveCache resource group.
7. As the liveCache administrator user, start SAP xserver manually on the node or zone that hosts the liveCache resource group.

       # su - lc-nameadm
       $ x_server start

   lc-name

     Lowercase name of liveCache database instance

8. Log on to SAP APO System by using your SAP GUI with user `DDIC`.
9. Go to transaction LC10 and change the liveCache host to the logical hostname you defined in Step 3.

       liveCache host: lc-logical-hostname
