Managing Serviceguard Extension for SAP Version B.05.10, September 2010

<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,
temporarily add relocatable address relocls_s to the cluster node with "cmmodnet
-a -i relolc_s network" for testing the following commands.
Run the following command as APO Administrator and directly exit the dbmcli prompt with
the quit command:
# dbmcli -U <user_key>
# dbmcli on <hostname> : <LCSID>> quit
A <hostname> is returned in string of the dbmcli prompt above. If this hostname is not the
relocatable hostname <relocls_s>, a user mapping has to be created. If it is not, the XUSER
mapping has to be recreated. Example:
mv .XUSER.62 .XUSER.62.ORG
DEFAULT key
dbmcli -n <reloclc_s> -d <LCSID> -u SAPRIS,SAP -uk DEFAULT -us\ SAPRIS,SAP -up "SQLMODE=SAPR3; TIMEOUT=0;
ISOLATION=0;"
ADMIN/ key
# dbmcli -n <reloclc_s> -d <LCSID> -u control,control -uk c -us\ control,control
ONLINE/ key
# dbmcli -n <reloclc_s> -d <LCSID> -u superdba,admin -uk w -us\ superdba,admin
LCA key
# dbmcli -n <reloclc_s> -d <LCSID> -us control,control -uk 1LCA<reloclc_s> -us \ control,control
NOTE: Refer to the SAP documentation to learn more about the dbmcli syntax. After recreation
always check the connection:
# dbmcli -U <user_key>
# dbmcli on <reloclc_s> : <LCSID>> quit
liveCache Installation Step: GS240
Distribute the XUSER mappings by distributing the file/home/<sid>adm/.XUSER.<version>
to all APO package nodes.
General Serviceguard Setup Changes
Dependent from the storage option chosen, the globally available directories need to be added
to different existing Serviceguard packages. The following installation steps require that the
system has already been configured to use the automounter feature. If this is not the case, refer
to installation steps IS730 to IS770 found in chapter 3 of this manual.
liveCache Installation Step: GS250
For option 1:
A logical volume for /sapdb/programs should already exist within the NFS package part of
the dbci<APOSID> package. It contains the MAXDB client libraries. In case of a two-package
installation for APO, the logical volume is part of the NFS package part of the db<APOSID>
package.
1. Copy the content of /sapdb/programs from the liveCache primary node to this logical
volume. It should be a superset of the files that already exist.
2. Make sure /sapdb/programs exists as empty mountpoint on all hosts of the liveCache
and APO packages.
3. Add the following entry to /etc/auto.direct. on all liveCache package nodes:
/sapdb/programs <relocdbci_s>:/sapdb/programs.
