Serviceguard Extension for RAC A.11.16.00

[Omar Alvi_1]

Hi,

I was trying to install the patch PHSS_31079 on an HP-UX 11.11 system with ServiceGuard Version A.11.16 installed.

The patch installation aborts with the following message.

NOTE: The patch fileset "PHSS_31079.CM-NMAPI,r=1.0" may only be
installed upon a previously installed base fileset. The
specification for this base fileset is
"SG-NMAPI.CM-NMAPI,fr=A.11.16.00,v=HP". Since there is no
fileset on the target or selected from the source which
matches this specification, fileset
"PHSS_31079.CM-NMAPI,r=1.0" will be excluded.
* Executing preDSA command.

What is this required base fileset in addition to ServiceGuard software.

Appreciate any assistance.

Thanks and Regards,

It thinks SG isn't installed.

Is RAC installed?

do a swlist to verify the level of SG.

Hi,

Make sure you have installed,

MC service guard &
RAC extension for Service guard.

Hi,

Well, all I have installed is the following

ServiceGuard
ServiceGuard Manager

It seems as though the ServiceGuard extension for RAC is a product costing more than SG itself.

So the patch won't install.

Another side query, how far is it possible to integrate Oracle application in the ServiceGuard Package without having bought the oracle ServiceGuard Toolkit.

Can the monitoring and failover be done effectively without the toolkit.

Thanks and Regards,

Hi,

Up to my knowledge you must have MC/SG RAC extension to install Oracle RAC, becuase it provides group membership for RAC nodes.

If you are planing a standard oracle (cold fail over - Active/Passive) then MC/SG alone is enough. But still the oracle services cannot be monitored by MC/SG.
For monitoring the standard applications you have to have "Enterprise Cluster tool kit"

To be perfect,

For standard Oracle DB
MC/SG & Enterprise cluster toolkit are required.

For Oracle RAC,
MC/SG & MC/SG RAC Extension are required.

Contact HP sales rep, more info.

The Toolkit is *not* required. I've done many SG+oracle installation without the toolkit. You can make your own package for just about anything.

What version of Oracle are you installing?
10g definitely does *not* *require* SG or SGextRAC (I've just done such an installation). 10g comes with Oracle's own cluster services (CRS) and Volume Manager (ASM).

However, without SG, you won't have *local* network failover (CRS handles network failover to another node). Without SGextRAC, you won't have shared raw LVM so you will use ASM, which uses shared raw devices, but Oracle handles all the internal files -- there is no OS filesystem and you will not see any files at the OS level ( you don't with shLVM either, unless you use a clustered Filesystem like Veritas). I think that ASM is pretty nice. However, you lose a little flexibility in that the *entire* raw device will be used. With shLVM, you could could create and add LVOLs of any size at any time, without being committed to the entire device. ASM will also do the mirroring if you want. E.g., when the devices are disks; but he likes at least pairs of disks of the same size -- not unusual. If the devices are Array LUNs RAID5 or RAID1+0, then you can have ASM not do any mirroring and add LUNs of any size. Bottom line: ASM +OMF(Oracle managed files) +BFT (Big-file tablespaces) makes a good combination.
