Active-Active Configurations

Hi,
I'm interested to know if openmq supports a full active-active clutser configuration which results in best high-availiability and scalability.
If it isn't, do you know a solution that does support such a configuration?
Tnx.

Is it possible to configure NLB clustering in Active/Active mode.

Hello Guys,
Just wanted to know If I can manually configure my NLB cluster to work in ACTIVE/ACTIVE mode as we can do for Microsoft fail over clustering.
Thanks & Regards
Amit Pal Singh

Hi Amit Pal Singh,
I think you must some misunderstand about the failover and NLB, I assume you are trying to install the Failover cluster, you can refer the following article to install the
A-A failover cluster.

Two node - Two site Active/Active DAG Configuration

Information
Both sites exist in a single AD domain
Site A
1 Exchange 2013 multi-role server (CAS + MBX)
Server will contain mailboxes for individuals who work in Site A
Server will contain database copies of databases in Site B
Site B
1 Exchange 2013 multi-role server (CAS + MBX)
Server will contain mailboxes for individuals who work in Site B
Server will contain database copies of databases in Site A
Goal
To create a configuration where users who work in Site A have their mailboxes active in Site A and users who work in Site B have their mailboxes active in Site B.
Questions
Since this DAG has an even number of members, where do I place the witness server? Do I need two witness servers, one in each site?
It seems to me as long as both sites can still communicate, I only need one witness server to maintain quorum.
To my current understanding, if Site A has a witness server, and Site A looses its WAN connection, Site B's databases are going to go offline because it has lost quorum.
I'm assuming if I placed a witness server in each site, and one of the sites lost its WAN connection, then I'd be placed in a split-brain scenario as both sites would still think it had quorum. Is this accurate?
The company has given me a limited budget hence the reason for only having two exchange servers in this setup. Is my only recourse to have four nodes (two nodes per DAG) in this active\active scenario? If the company says they absolutely cannot spend money
on two more servers, could I use the current setup in an active\passive configuration?
Thanks!

You would need to place the File Share Witness in a 3rd datacenter for automatic failover, otherwise depending which DC the FSW is ( and you can only have one FSW per DAG active a time), then in case of a WAN or DC failure, the databases will be active in
the DC that has quorum.
If the FSW is in Site A and Site A goes down, then quorum is lost and Site B will need to be manually swithed over using this procedure:
http://technet.microsoft.com/en-us/library/dd351049(v=exchg.150).aspx
To be truly active/active in both DCs, then you would need to 2 DAGs with each respective FSW in each DC that has the preferred user base.

DB & CI - MSCS Active-Active Cluster configuration.

Hi all,
I could find several solutions searching for posts about Clustering, but am still having doubts.
We are going to install servers for our erp application - SAP. One server shall be DB server (Database) and another CI server (Content). OS - Windows Server 2003 -R2, Enterprise Edition and SQL 2005.
We want to have both these servers to be clustered as Active-Active. Going through the posts, Active-Active does not seem to be recommended from microsoft compared to Active-Passive cluster.
Can someone please guide about this ?
Also if someone can please provide link - how to configure Active-Active cluster in Windows server 2003 for SAP servers. Sort of step-by-step guide if available ?
Thanks in advance.
Kalpesh

Hi,
You don't tell us which SAP ERP product you want to be clustered...
ECC is different from R/3 for this matter...
SAP MSCS Clusters are active-active in the way that each node has its own role in nominal configuration (no fail over).
SAP MSCS clusters are Active-PAssive in the way that tha database or SAP components run on only one single node.
For ECC6, you have SQL server running on one node and the SCS running on the other node.
If you want to really use the cpus of the second node, you can install the CI (which is in fact the first DI) on the second node.
For MSCS, you have to follow the configuration explained in the SAP installation guide. Otherwise your system will not be supported.

Olivier

Configure 10g OAS Active Active Topology

Hi,
Our requirement is to deploy 10g OAS (Forms & Reports) on two servers for load balancing, below are my questions,

Triggers in active-active configurations

Hi,
I am new to Goldengate and are looking for best practices regarding database triggers when replicating with Goldengate in an active-active configuration.
Will best practices be to not replicate tables which are filled by triggers or is it some magic parameters?
Scenario: To databases, both with active users. Tab1 in both databases has a trigger updating tab2. Will best practices be to just replicate tab1 with Goldengate?
Thank You for Your help!

HI,

Valid for Replicat for Oracle. Prevents triggers from firing on target objects that are configured for replication with Oracle GoldenGate. You can use this parameter for Oracle 10.2.0.5 and later patches, and for Oracle 11.2.0.2 and later, instead of manually disabling the triggers. To use this option, the Replicat user must be an Oracle Streams administrator, which can be granted by invoking dbms_goldengate_auth.grant_admin_privilege.

RAC Active/Active VS Active/Passive 11g Configuration

Thanks in advance.
I appreciate your experience with implementing RAC in an Active/Active VS Active/Passive Configuration of 11g RAC.
Much of my experience has been with Active/Active to take full advantage of performance capability of both nodes (2 node cluster). As such, I don't see the advantages of Active/Passive RAC configuration.

The benefit is that you can save on licensing costs while gaining availability

Replicate filter to identify inconsitence in active-active configurations

Hi,
I am looking for the best way for Goldengate to handle consistency in an active-active configuration.
I would like every transaction to be checked at the target by the replicate process if the before value of every column match the value in the target table column and row.
My databases have 400 tables and I am looking for an easy configuration to identify transactions where the before values doesnt match the actual value in the target table.
One solution is to trap the filter exception for each table, but I hope You may help me with a better solution:

I don't think that LMS has a feature for HA installation.
You will find that in the document
http://www.cisco.com/en/US/prod/collateral/netmgtsw/ps6504/ps6528/ps2425/ps7196/prod_white_paper0900aecd80695cad.pdf
on page 20 in chapter "7.1 Redundant-Server Scenario".
But there is an solution with two identical servers, one as master and the other as slave.
Details you will find in the document.

- X server with incompatible libxkbfile implementation

Or "evdev" if I enabled hotplugging

Doesn't matter if I use hotplugging or not (cuz even if I do away with xorg.conf, I still encounter this problem). I am stuck with the US layout, and unable to Ctrl-Alt-Backspace, or Ctrl-Alt-F1 etc.
Any suggestions?

ACTIVE/ACTIVE Disaster Recovery configuration

If I have two separate 10.2.0 RAC databases in two separate geographical locations and each database is receiving updates and sending the changes to the other database via Streams, how would you configure a disaster recovery solution for this?
In this scenario, each database is intended to be a copy of the other. It is an ACTIVE/ACTIVE type of setup.
Do you need also have a data guard database for each of these databases to support disaster recovery?
Thanks for your feedback.

ASA Active/Active Configuration

Dear All,
In configuring Active/Active mode of ASA, most examples are stating using
2 customers for Active/Active. If I only get 1 customer with 4 interfaces as
following:
1) Outside
2) Inside
3) DMZ
4) VPN
Can I still use the Active/Active mode?
If so, then how to allocate the interfaces to the 2 failover groups? Let
assume:
Failover group 1: Outside and DMZ
Failover group 2: VPN and Inside
That means ASA_A is primary of Group1, while ASA_B is primary of Group2. If
so, is the traffic between Outside and Inside has problem? Since they are
crossing the 2 failover group on the 2 ASA.
Please correct me and my assumption. A sample configuration would be much appreciate.
Thanks in advance.
Br,
Sam

Thank you for the reply Jennifer.
I was reffering to the following document:
http://www.cisco.com/en/US/docs/security/asa/asa80/configuration/guide/failover.html#wp1091405
Failure Event
Policy
Active Action
Standby Action
Notes
Failover link failed during operation
No failover
Mark failover interface as failed
Mark failover interface as failed
You should restore the failover link as soon as possible because the unit cannot fail over to the standby unit while the failover link is down.
Stateful Failover link failed
No failover
No action
No action
State information becomes out of date, and sessions are terminated if a failover occurs.
I think I should rephrase question 2) If I have two seperate links for Failover and Stateful failover, will that fix my problem?
How can I configure seperate Failover and Stateful failover links? If I understand correctly, they are more than just redundant links.
Sorry I didn't accurately phrase my original post.
Thank you
