Linux Setup
This section describes how to setup Serviceguard extension for SAP with Linux.
Clustered Node Synchronization
1. Repeat the steps in this section for each node of the cluster that is different from the primary.
2. Logon as root to the primary host and prepare a logon for each of its backup hosts.
liveCache installation Step: LC030
Synchronize the
/etc/group and /etc/passwd
files. The liveCache installation has created a <lcsid>adm
user belonging to the
sapsys
group.
Make sure the user and group exist on all nodes and that UID and GID are consistent across the nodes.
liveCache installation Step: LC040
Synchronize the
sql<nn>
entries from the
/etc/services
file between the nodes to match the entries on
the primary node. Usually you will find service entries for sql6 and sql30.
liveCache installation Step: LC050
Change the Linux kernel on the backup nodes to meet the SAP liveCache requirements as specified in the
SAP liveCache installation documents.
liveCache installation Step: LC060
Do the following to continue.
1. Copy the content of the <lcsid>adm home directory to the backup node. This is a local directory on
each node.
2. Rename the environment scripts on the secondary nodes. Some of the environment scripts may not exist.
For example:
su - <lcsid>adm
mv .dbenv_<primary>.csh .dbenv_<secondary>.csh
mv .dbenv_<primary>.sh .dbenv_<secondary>.sh
For liveCache 7.6:
su - <lcsid>adm
mv .lcenv_<primary>.csh .lcenv_<secondary>.csh
mv .lcenv_<primary>.sh .lcenv_<secondary>.sh
NOTE: Never use the relocatable address in these file names.
liveCache installation Step: LC061
Copy file
/etc/opt/sdb
to the second cluster node. This file contains global path names for the liveCache
instance.
liveCache installation Step: LC062
Verify that the symbolic links listed below in directory /var/spool/sql exist on both cluster nodes.
dbspeed -> /sapdb/data/dbspeed
diag -> /sapdb/data/diag
fifo -> /sapdb/data/fifo
ini
ipc -> /sapdb/data/ipc
