HP Serviceguard Extension for SAP (SGeSAP) Copy the sidadm home directory to the backup nodes

NOTE: Beware of copying over into /etc/passwd if your HP-UX is running in Trusted System mode.

Table 3-3 Password File Users

username	UID	GID	home directory	shell
<sid>adm

ora<SID>

sqd<SID>

sqa

sap<dbsid>db

Installation Step: IS090

Look at the service file, /etc/services, on the primary side.

Replicate all services listed in Table 3-4 Services on the Primary Node that exist on the primary node onto the backup node.

Table 3-4 Services on the Primary Node

Service name	Service port
sapdp<INR>

sapdp<INR>s

sapgw<INR>

sapgw<INR>s

sapms<SID>

orasrv

sapdb<INR>

saphostctrl

saphostctrls

Installation Step: IS100

Change the HP-UX kernel on the backup node to meet the SAP requirements.

Compare the Tunable Parameters section of /stand/system on all nodes. All values on the backup nodes must reach or exceed the values of the primary node.

Install all HP-UX patches that are recommended for Serviceguard and patches recommended for SAP. Build a new kernel with mk_kernel(1m) on each backup node if /stand/system was changed. Installation Step: IS110

Copy the <sid>adm home directory to the backup node(s).

This is a local directory on each node. Default home directory path is /home/<sid>adm. Installation Step: IS120

On the second node, in the <sid>adm home directory the start, stop and environment scripts need to be renamed.

If some of the scripts listed in the following do not exist, these steps can be skipped.

su - <sid>adm

mv startsap_<primary>_<INR> startsap_<secondary>_<INR> mv stopsap_<primary>_<INR> stopsap_<secondary>_<INR> mv .sapenv_<primary>.csh .sapenv_<secondary>.csh

mv .sapenv_<primary>.sh .sapenv_<secondary>.sh mv .dbenv_<primary>.csh .dbenv_<secondary>.csh
