Sun Cluster 3.0 MQ Series 5.2 configuration
Hi All,
we have to review MQ Series installation/configuration on 2 solaris 8 Clustered with Sun Cluster 3.0 machines. The present configuration has a global filesystem /var/mqm with one queue manager.
According to Sun Cluster 3.1 dataservice for websphere MQ(5.3 ndr) there are 2 ways of filesystem layout
FFS: with local qmgrs (data and log) at each cluster node
GFS: with global filesystem qmgrs (data and log).
Are there any special consideration about shmem and ipc directories in <qmgr>/data?
Does this scenario also apply to 3.0 /5.2 ?
Does FFS configuration allow persistant messages failover at takeover?
Are there any dataservices/docs available for MQ on 3.0?
Thanks in advance.
To deploy multiple qmgrs requires /var/mqm to be mounted as a GFS. The reason for this is to overcome IPC key clashes. The recommended file system layout is as follows -> represents a symlink, assuming two qmgrs - qmgr1 & qmgr2
Using FFS (recommended - /local/mqm etc.. are mounted as FFS with /etc/vfstab)
/var/mqm -> /global/mqm
/global/mqm/qmgrs/qmgr1 -> /local/mqm/qmgr/qmgr1
/global/mqm/qmgrs/qmgr2 -> /local/mqm/qmgr/qmgr2
/global/mqm/log/qmgr1 -> /local/mqm/log/qmgr1
/global/mqm/log/qmgr2 -> /local/mqm/log/qmgr2
Using GFS (mainly early SC3.0 as HAStoragePlus wasn't available until later on)
All mounted as GFS with /etc/vfstab
/var/mqm -> /global/mqm
/global/mqm/qmgrs/qmgr1
/global/mqm/qmgrs/qmgr2
/global/mqm/log/qmgr1
/global/mqm/log/qmgr2
Finally, FFS (Failover File System) is recommend because, at present, whenever GFS is used for the qmgr & log files, MQ Series is unable to determine that the qmgr may have been started on another node. e.g. Assuming GFS, and MQ Series is started on Node A, it is possible (but don't do it) to start MQ Series on Node B.
The Sun Cluster Agent provides some protection against this. Instead it's recommened to deploy FFS as above.
The agent for WebSphere MQ for SC 3.1 is available and supported on SC3.0 update 3 as well as SC3.1. There is also a patch available for the WebSphere MQ Agent which deals with IPC cleanup, for single or multiple qmgrs.
Docs available can be found at
http://docs.sun.com/db/prod/7192#hic - Just select Sun Cluster Data Service for WebSphere MQ
Finally, the above scenario also applies to SC3.0/5.2 as well as SC3.1/5.3 and either GFS/FFS allow for persistant messages to be available after a failover.

Neil

Hi all,
Need some help from all out there
In our Sun Cluster 3.1 Data Service for Oracle RAC 9.2.0.7 (Solaris 9) configuration, my team had encountered
ora-29701 *Unable to connect to Cluster Manager*
during the startup of the Oracle RAC database instances on the Oracle RAC Server resources.
We tried the attached workaround by Oracle. This workaround works well for the 1^st time but it doesnt work anymore when the server is rebooted.
Kindly help me to check whether anyone encounter the same problem as the above and able to resolve. Thanks.
Bug No. 4262155
Filed 25-MAR-2005 Updated 11-APR-2005
Product Oracle Server - Enterprise Edition Product Version 9.2.0.6.0
Platform Linux x86
Platform Version 2.4.21-9.0.1
Database Version 9.2.0.6.0
Affects Platforms Port-Specific
Severity Severe Loss of Service
Status Not a Bug. To Filer
Base Bug N/A
Fixed in Product Version No Data
Problem statement:
ORA-29701 DURING DATABASE CREATION AFTER APPLYING 9.2.0.6 PATCHSET
*** 03/25/05 07:32 am ***
TAR:
PROBLEM:
Customer applied 9.2.0.6 patchset over 9.2.0.4 patchset.
While creating the database, customer receives following error:
ORA-29701: unable to connect to Cluster Manager
However, if customer goes from 9.2.0.4 -> 9.2.0.5 -> 9.2.0.6, the problem does not occur.
DIAGNOSTIC ANALYSIS:
It seems that the problem is with libskgxn9.so shared library.
For 9.2.0.4 -> 9.2.0.5 -> 9.2.0.6, the install log shows the following:
installActions2005-03-22_03-44-42PM.log:,

For 9.2.0.4 -> 9.2.0.6, install log shows:
installActions2005-03-22_04-13-03PM.log:, [libcmdll.so ->%ORACLE_HOME%/lib/libskgxn9.so 64274 plats=1=>[46] langs=-554696704=>[en]] does not exist.
This means that while patching from 9.2.0.4 -> 9.2.0.5, Installer copies the libcmdll.so library into libskgxn9.so, while patching from 9.2.0.4 -> 9.2.0.6 does not.
ORACM is located in /app/oracle/ORACM which is different than ORACLE_HOME in customer's environment.
WORKAROUND:
Customer is using the following workaround:
cd $ORACLE_HOME/rdbms/lib make -f ins_rdbms.mk rac_on ioracle ipc_udp

Does sun Cluster 3.0/3.1 HA Oracle agent support to use Oracle spfile?
When defining the resource, the 'parameter_file' properties is usually sets to the Oracle pfile. Is it possible to use Oracle spfile?
It is said if leaving 'parameter_file' NULL, it will be default to Oracle default. Suppose leaving it NULL and with Oracle spfile created in default location, will it use the spfile?You did not specify which Sun Cluster version and Oracle version you are running.
Within SC 3.1 my understanding is that beginning with Oracle 9i it is possible to use the spfile.
If you leave the "parameter_file" property empty (NULL) then the default behaviour for 9i should work:
search under $ORACLE_HOME/dbs in the order:
1. spfile$(ORACLE_SID}.ora
2. spfile.ora
3. init${ORACLE_SID}.ora

SAP 7.0 on SUN Cluster 3.2 (Solaris 10 / SPARC)
Dear All;
i'm installing a two nodes cluster (SUN Cluster 3.2 / Solaris 10 / SPARC), for a HA SAP 7.0 / Oracle 10g DataBase
SAP and Oracle softwares were successfully installed and i could successfully cluster the Oracle DB and it is tested and working fine.
for the SAP i did the following configurations
# clresource create -g sap-ci-res-grp -t SUNW.sap_ci_v2 -p SAPSID=PRD -p Ci_instance_id=01 -p Ci_services_string=SCS -p Ci_startup_script=startsap_01 -p Ci_shutdown_script=stopsap_01 -p resource_dependencies=sap-hastp-rs,ora-db-res sap-ci-scs-res

and when trying to bring the sap-ci-res-grp online # clresourcegroup online -M sap-ci-res-grp
it executes the startsap scripts successfully as following

ARSSESHi all.
I am having a similar issue with a Sun Cluster 3.2 and SAP 7.0
Scenrio:
Central Instance (not incluster) : Started on one node
Dialog Instance (not in cluster): Started on the other node
When I create the resource for SUNW.sap_as like
clrs create --g sap-rg -t SUNW.sap_as .....etc etc
in the /var/adm/messages I got lots of WAITING FOR DISPACHER TO COME UP....
Then after timeout it gives up.
Any clue? What does is try to connect or waiting for? I hve notest that it's something before the startup script....

For registering logical hostname resource in failoover group, what exactly i need to specify
for example, i have two nodes in sun cluster , How to create or configure a logical hostanme and it should point to which IP Address ( Whether it should point to IP addresses of nodes in sun cluster). Can i get clarification on this?Thanks Thorsten for ur continue help...

File System Sharing using Sun Cluster 3.1
Hi,
I need help on how to setup and configure the system to share a remote file system that is created on a SAN disk (SAN LUN ) between two Sun Solaris 10 servers.
The files in the remote system should be read/writabe from both the solaris servers concurrently.
As a security policy NFS mount is not allowed. Some one suggested it can be done by using Sun Cluster 3.1 agents on both servers. Any details on how I can do this using Sun Cluster 3.1 is really appreciated.
thanks
SureshYou could do this by installing Sun Cluster on both systems and then creating a global file system on the shared LUN. However, if there was significant write activity on both nodes, then the performance will not necessarily what you need.
What is wrong with the security of NFS? If it is set up properly I don't think this should be a problem.
The other option would be to use shared QFS, but without Sun Cluster.
Regards,
Tim

In the Installation of RAC the routine will ask me which Interface I will use for RAC Interconnect and I do not know if it does not matter which Interface I choose, because I nevertheless in any case I have an SPOF.
Can anybody help??
Thank you very muchSorry for the late reply, but the interface to pick is the clprivnet0. This load-balances over the available private interconnects under the covers and so does not represent a single point of failure.

Sun Cluster with Netapps - iSCSI quorum and network port
I am proposing Sun cluster with Netapps 3020C.
May I know
1) OS is Solaris 9. The SUN OSP says that we need to obtain an iSCSI license from Netapps. Is this the iSCSI initiator software for Solaris 9 to talk to the NAS quorum? Or do I need to purchased a 3rd party iSCSI initiator ?
2) We provide 2 network ports for the Netapps private NAS LAN. Is it a must to cater another dedicated network port for the iSCSI communication with the quorum?
3) If we need purchase a 3rd party iSCSI initiator, where can we get this? I have checked Qlogic and Cisco, they are both not suitable for my solution.
Appreciate your helpHi,
1) OS is Solaris 9. The SUN OSP says that we need to
obtain an iSCSI license from Netapps. Is this the
iSCSI initiator software for Solaris 9 to talk to the
NAS quorum? Or do I need to purchased a 3rd party
iSCSI initiator ?Have a look at http://docs.sun.com/app/docs/doc/817-7957/6mn8834r2?a=view
I read the "Requirements When Configuring NAS Devices as Quorum Devices"
section as this is the license for the iSCSI inititator software.
So you need to enable iSCSI on the netapps box and need to install a package from netapps (NTAPclnas) on the cluster nodes.
2) We provide 2 network ports for the Netapps
private NAS LAN. Is it a must to cater another
dedicated network port for the iSCSI communication
with the quorum?Have a look at http://docs.sun.com/app/docs/doc/819-0580/6n30eahcc?a=view#ch4_quorum-9
I don't read such a requirement there.
3) If we need purchase a 3rd party iSCSI initiator,
where can we get this? I have checked Qlogic and
Cisco, they are both not suitable for my solution.
Appreciate your helpI don't thibk you need such a 3rd party iSCSI initiator, unless this is stated in the above docs.

Rename Sun Cluster Resource Group
Hi All,
We have a 2 node Sun Cluster 3.0 running on 2 x V440 servers. We want to change the resource group.
Can I use "scrgadm -c -g RG_NAME -h nodelist -y property" command to change the resource group name. Can I do this online while the clusters are running or do I need to bring the cluster to mainenance mode? Any help would be appreciated.
Thanks.You cannot rename a resource group in that way in Sun Cluster.
You have two options:
-Recreate the resource group with the new name
-Use an unsupported procedure to change the name in the CCR. This requires downtime of both nodes and as it is unsupported I am not going to describe it here. If that is what you want to do, please log a call with Sun.
If you think renaming resource groups is a useful feature may I also ask you to contact your Sun Service representative so that they can take proper action to log an RFE for the feature. -
Sun Cluster.. Why?
What are the advantages of installing RAC 10.2.0.3 on a Sun Cluster.? Are there any benefits?
Oracle 10g onward, there is no such burning requirement for Sun Cluster (or any third party cluster) as far as you are using all Oracle technologies for your Oracle RAC database. You should Oracle RAC with ASM for shared storage and that would not require any third party cluster. Bear inmind that
You may need to install Sun Cluster in the following scenarios:
1) If there is applicaiton running with in the cluster along with Oracle RAC database that you want to configure for HA and Sun Cluster provide the cluster resourced (easy to use) to manage and monitor the application. THIS can be achieved with Oracle Clusterware but you will have to write your own cluster resource for that.
2) If you want to install cluster file system such as QFS then you will need to install the Sun Cluster. If this cluster is only running the Oracle RAC database then you can rely on Oracle technologies such as ASM, raw devices without installing Sun Cluster.
3) Any certification conflicts.
Any correction is welcome..
