liveCache Installation Step: GS220
Run SAP transaction LC10 and configure the logical liveCache names LCA and LCD to listen to the relocatable
IP of the liveCache package.
liveCache Installation Step: GS230
Do the following to continue:
1. Configure the XUSER file in the APO user home and liveCache user home directories. If an .XUSER file
does not already exist, you must create it.
2. The XUSER file in the home directory of the APO administrator and the liveCache administrator keeps
the connection information and grant information for a client connecting to liveCache. The XUSER
content needs to be adopted to the relocatable IP the liveCache is running on.
▲ To list all mappings in the XUSER file, run the following command as sidadm of the APO user:
# dbmcli -ux SAPR3,SAP -ul
For liveCache 7.6 or higher:
su - <lcsid>adm
dbmcli -ux SAP<LCSID>,<password> -ul
This command produces a list of MAXDB user keys that may be mapped to the liveCache database schema
via a local hostname. SAP created keys commonly include c, w and DEFAULT. If a mapping was created
without specifying a key, entries of the form <num><LCSID><hostname>, e.g. 1LC1node1 exist. These
will only work on one of the cluster hosts.
▲ To find out if a given user key mapping <user_key> works throughout the cluster, the relocatable
address should be added to the primary host using cmmodnet -a.
Run the following command as APO Administrator:
# dbmcli -U <user_key>
quit exits the upcoming prompt:
# dbmcli on <hostname> : <LCSID>> quit
<hostname> should be relocatable. If it is not, the XUSER mapping has to be recreated. Example:
mv .XUSER.62 .XUSER.62.ORG
DEFAULT key
