liveCache Installation Step: LC211
Log in on the primary node that has the shared logical volumes mounted.
Create a symbolic link that acts as a hook that informs SAP software where to find the liveCache
monitoring software to allow the prescribed interaction with it. Optionally, you can change the
ownership of the link to sdb:sdba.
ln -s /etc/cmcluster/<LCSID>/saplc.mon /sapdb/<LCSID>/db/sap/lccluster
liveCache Installation Step: LC216
For the following steps the SAPGUI is required. Logon to the APO central instance as user
SAP*.
Start transaction /nlc10 and enter LCA for the logical connection.
/nlc10 -> Logical connection -> LCA -> liveCache -> Create/Change/Delete Connection
Change liveCache server name to the virtual IP name for the liveCache and save it.
Change the liveCache instance name to <LCSID>. Redo the above steps for LDA.
SGeSAP Legacy Package Configuration
This section describes how to configure the SGeSAP lc package.
liveCache Installation Step: LC165
Install the product depot file for SGeSAP (T2803BA) using swinstall (1m) if this has not been
done already.
The installation staging directory is /opt/cmcluster/sap. All original product files are copied
there for reference purposes.
liveCache Installation Step: 167
Copy the relevant SGeSAP files for liveCache to the cluster directory:
mkdir /etc/cmcluster/<LCSID>
chown root:sapsys /etc/cmcluster/<LCSID>
chmod 775 /etc/cmcluster/<LCSID>
cp /opt/cmcluster/sap/SID/saplc.mon /etc/cmcluster/<LCSID>
cp /opt/cmcluster/sap/SID/sapwas.cntl /etc/cmcluster/<LCSID>
cp /opt/cmcluster/sap/SID/customer.functions/ /etc/cmcluster/<LCSID>
cp /opt/cmcluster/sap/SID/sap.config /etc/cmcluster/<LCSID>
If this has not already been done, also copy the system independent integration files:
cp /opt/cmcluster/sap/*.functions /etc/cmcluster
liveCache Installation Step: LC170
Create standard package control and configuration files:
cd /etc/cmcluster/<LCSID>
cmmakepkg -s lc<LCSID>.control.script
cmmakepkg -p lc<LCSID>.config
Both files need to be adapted according to reflect the filesystem layout option chosen and the
individual network setup. For general information on how to customize the package control and
configuration files refer to the Managing Serviceguard manual at
www.hp.com/go/hpux-serviceguard-docs —> HP Serviceguard —> User guide.
• For lc<LCSID>.config the following settings are strongly recommended:
PACKAGE_NAME lc<LCSID>
PACKAGE_TYPE FAILOVER
RUN_SCRIPT /etc/cmcluster/<LCSID>/lc<LCSID>.control.script
HALT_SCRIPT /etc/cmcluster/<LCSID>/lc<LCSID>.control.script
SERVICE_NAME SGeSAPlc<LCSID>
• Forlc<LCSID>.cntl the following settings are strongly recommended:
