User's Guide

If the local executable directory only holds links, sapcpe is not configured correctly. It is not an option to
manually copy the local executables in this case. The next instance restart would replace the local copies
with symbolic links.
For latest information on how to utilize sapcpe refer to the SAP online documentation.
Installation Step: IS060
Clustered SAP Instances must have instance numbers that are unique for the whole cluster.
For a clustered instance with instance number <INSTNR> execute the command:
ls -d /usr/sap/???/*<INSTNR>
It should not reply any match on all nodes. Otherwise refer to the SAP documentation how to change instance
IDs for the relevant instance type. It might be simpler to reinstall on of the conflicting instances.
Installation Step: IS065
If local executables are created (refer to step IS050) and failover nodes have no internal application server
with local executables installed, distribute the directory tree /usr/sap/<SID>/SYS from the primary node.
Do not use rcp(1), it will follow all links and copy a lot of files from the shared disks that are not needed.
For example, on the primary node:
cd /usr/sap/<SID>/SYS
find . -depth -print | cpio -o >/tmp/SYS.cpio
Use ftp(1) to copy the file over to the secondary node. On each alternate node:
su - <sid>adm
mkdir -p /usr/sap/<SID>/SYS
cd /usr/sap/<SID>/SYS
cpio -id </tmp/SYS.cpioexit
Cluster Node Synchronization
Repeat the steps in this section for each node of the cluster that is different than the primary.
Logon as root to the system where the SAP Central Instance is installed (primary host) and prepare a logon
for each of its backup hosts - if not already available.
Installation Step: IS070
Open the groupfile, /etc/group, on the primary side.
If any of the groups listed in Table 3-2 - Groupfile File Groups exist on the primary node and they do not
exist on the backup node, copy them from the primary node to the backup node. If any group exists, verify
that it has the same GID on both the primary and backup nodes. Merge the group members lists.

Installation Step: IS080
Open the password file, /etc/passwd , on the primary side.
If any of the users listed in Table 3-3 Password File Users exist on the primary node, recreate them on the
backup node. Assign the users on the backup nodes the same user and group ID as the primary nodes.
