HP Serviceguard Extension for SAP (SGeSAP) SAP Abap Engine specific configuration steps, Cdpro

SAP ABAP Engine specific configuration steps

Logon as <sid>adm on the primary node on which a Central Instance or the System Central Services have been installed. The appropriate Serviceguard package should still run on this host in debug mode.

Installation Step: IS1100

For SAP Central Instance virtualization, change into the profile directory by typing the alias:

cdpro

In the DEFAULT.PFL change the following entries and replace the hostname with the relocatible name if you cluster a ci component. For example:

SAPDBHOST = <relocdb> rdisp/mshost = <relocci> rdisp/sna_gateway = <relocci> rdisp/vbname = <relocci>_<SID>_<instnr> rdisp/btcname = <relocci>_<SID>_<instnr> rslg/collect_daemon/host = <relocci>

If you don't have Replicated Enqueue:

rdisp/enqname = <relocci>_<SID>_<instnr>

The following parameters are only necessary if an application server is installed on the adoptive node. For example:

rslg/send_daemon/listen port

rslg/collect_daemon/listen port

rslg/collect_daemon/talk port

Optional Step: IS1110

If you want to use the DB-Reconnect functionality for ABAP Instances:

Add entries to:

•/sapmnt/<SID>/profile/<SID>_<INSTNAME><INR>

•Instance Profiles of all application servers that use DB-Reconnect For example:

rsdb/reco_trials = 15 rsdb/reco_sleep_time = 60 rsdb/reco_sosw_for_db = off(based on OSS #109036) rsdb/reco_sync_all_server = on

Installation Step: IS1120

In the instance profile of each clustered ABAP instance, two values have to be added to specify the virtual addressing,

For example in <SID>_DVEBMGS<INSTNR>:

SAPLOCALHOST = <relocci>

SAPLOCALHOSTFULL = <relocci>.<domain>

The parameter SAPLOCALHOSTFULL must be set even if you do not use DNS. In this case you should set it to the name without the domain name:

SAPLOCALHOSTFULL=<relocci>

The instance profile name is often extended by the hostname. You do not need to change this filename to include the relocatible hostname. SGeSAP also supports the full instance virtualization of SAPWAS 6.40 and beyond. The startsap mechanism can then be called by specifying the instance's virtual IP address. For this case, it is required to use the virtual IP addressing in the filenames of the instance profile and instance start profile. All references to the instance profiles that occur in the start profile need to be changed to include the virtual IP address instance profile filename.
