Oralce Failsafe Active/Active Configuration

Hello,
I have a question about Failsafe.
There is Active/Active configuration in Failsafe
(in section 3.1.2 http://otn.oracle.com/docs/tech/windows/failsafe/doc_library/331/concepts/makefs.htm#sthref359)
An example configuration is like this: 'In Figure 3-3, an Oracle database server is used for marketing on Node 1, and an Oracle database server is used for sales on Node 2. The cluster disks owned by Node 1 store the marketing files, and the cluster disks owned by Node 2 store the sales files. '
In this configuration , are there TWO independent database existing in cluster disks? so still single instance for each database?
And how to schedule the two nodes to activly access their own database during normal operation since MSCS allow cluster disk owned and accessed by only one node at a time.
Could anyone explain it ? Thanks a lot in advance.

You should be able to access Shared Services if foundation has started up even if there is an issue with RAF, if it is 11.1.2.3 then you have to log into workspace to be able to access Shared Services.
The directory configuration is held in the Shared Services registry, it can be exported/imported using the epmsys_registry utility.
Cheers

Unable to click 'Set and save as my Active Configuration for this project'

Environment: OWB 11.1.0.6 Client running on Windows XP Pro SP3 repository and targets on AIX (IBM UNIX).
I have created a new Configuration under a specific Project and I'd like to make this configuration the default whenever I login and select this Project.
There is a check box when I right click the Configuration and select 'Open Editor' that says 'Set and save as my Active Configuration for this project' but when I select the check box and try to click on 'OK' there is no response from the popup window and I have to click 'Cancel' to get out of the popup.
Any ideas on why this is happening and how to get around it??
Thanks very much.

Si
Good catch!! Restarting the app???? What a waste of time!! :-(
When I went back in the box was already checked! It must have known I was pissed at it!! :-)
Thanks for the help.

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,
I think this will help you....
SUPPRESSTRIGGERS |
NOSUPPRESSTRIGGERS
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.

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:
replicat r_gtmgts
userid goldengate, password goldengate
assumetargetdefs
discardfile ./dirrpt/r_gtmgts.dsc, append
GETUPDATEBEFORES
REPERROR (21000, EXCEPTION)

How do I set the active configuration back to default in NI MAX?

In the traditional NI-Daq menu of NI-MAX, I inadvertantly changed the active configuration away from the default, in which I had already set up channels. How do I get back to the configuration where I had the channels already set up?
Thanks,
KHC

Hello KHC,
So you configured some channels and now you want to go back to the default configuration? There isn't an option to right click on the task to change it. You will have to open a new task or modify the current task.
If you had created a task, modified it, saved it, modified it again, and wanted to go back to the first modification, you could just close MAX without saving the task. When you opened it again, the first modification would be there. Please let me know if you have any questions. Have a great day!
Sincerely,
Marni S.

Scripting active configuration deployment location for an oracle module

Hi,
Does anyone know how to script the setting of the active configuration deployment location for an oracle module?
I have executed the following which works fine but I can't figure out how to make it active so the module shows up in the control center to allow deployment.
I can of course do it manually in the design center by right clicking on the module in the design center, selecting 'Configure' and then (strangely) just selecting the location property which then automatically sets the active location and then it shows up in the control center.
OMBALTER ORACLE_MODULE 'MOD_EXT' ADD REFERENCE LOCATION 'MIG_EXT_LOCATION' SET AS DEFAULT
Oracle module MOD_EXT altered.
OMBALTER ORACLE_MODULE 'MOD_EXT' SET REFERENCE METADATA_LOCATION 'MIG_EXT_LOCATION'
Oracle module MOD_EXT altered.
Any ideas?
Regards,
Brad

Hi Brad,
before you set the location you have to set the correct configuration (in case you use more configurations than the default "DEFAULT_CONFIGURATION") as active configuration:
OMBCAC 'MY_CONFIGURATION'

Carsten.

Active-active Configuration

Hi all,
my customer wants to have an active - active configuration with his 2 CSS. To get the whole bandwitdh in our datacenter i want to connect this both with two routers in a crossover fashion. The first router should be the Default Gateway for the first CSS and the second router should be the DG for the second CSS. VRRP on both routers and on borth CSS should be also configured for the redundancy. Anyone to knows problems with this Configurations orsome pitfalls ??
thx for your comments.
bye joerg

Hi Joerg,
If you want full redundancy, it is good to have L2 switches between the CSSs and the routers. This in order to avoid having a single point of failure on the crossover cables between the CSSs and the routers.
Also, don't use the physical interfaces of the routers as the DG of the CSSs, the VRRP address should be the DG of the CSSs. The reason for this is that if you use the physical address as DG, the CSS pointing to this router would lose connectivity if this router fails, so it is better to use the floating IP as DG.
Besides that, I see you have a good picture of what you needs to be done to get this working. Thanks!
Regards,
Jose.

Error importing/activating Configuration tpz files

Hi All,
I am trying to import Configuration tpz files from one XI server to another. I have defined Transport Targets for all the Business Systems in the SLD also.
In Configuration, all the objects for a particular scenario are imported correctly from the tpz file, without any error. All these inactivated objects are grouped under a single change list called "XI 3.0 Import".
But while truing to activate this chage list, it gives error "Unable to activate <Receiver Determination> - Object <Receiver Communication Channel> does not exist".
I am also unable to activate any of the objects individually.It gives message "Unable to move object. Change lists were not part of the same import",
Any ideas on how to proceed?
Regards,
Puloma.

Hi All,
The problem is now solved.
We deleted the offending Receiver Determination objects from the Change List, and the rest of the change list was activated without any further errors. We now just have to re-create the Receiver dtermination objects.
Theo,
The communication channels in the original configuration were assisgned to scenarios.Also, re-creation of new Communication Channels was useless, as the resp. Business Systems were inactived.
However, the problem is now almost solved, as we don't have to replicate the entire Configuration manually, just the Receiver Determination.
Regards,
Puloma.

Dependent Activity Configuration

Hi I am creating a change request process workflow as per below requirement. I am facing issue at dependent activity stage. The activities in Release record are actually not starting automatically. When i open the release record and click on Run then everything
works perfect. I want to avoid this manual intervention in my workflow. Further i want to know that what are the other activities those can work with Dependent activity, I mean Review etc.
I have configure the Activities as below:
CHANGE REQUEST
02 Separate Review Activities for Approval> Then> Dependent Activity with Linked to Release Record and Then one Manual Activity.
RELEASE RECORD
01 Manual Activity for Test, 01 RA for Approval Pre-Production, Then 01 MA for Pre-Production deployment.

Hi,
I have to say that I haven't found out other activities except for change request that can work with Dependent activity. And if you want to automatic run, you may try Orchestrator.
Here is a thread for your reference:

XI - Error when activating configuration

We did a "clean" install of PI 7.0 on Windows 2003 server / MSSQL and performed the post-installation config all as per instalation guide. All works fine, except when activating PI config from the Integration Directory. The activation works, but after a few seconds the following error comes up in the PI configuration:

Hello Johan ,
Check this out :
URL was these :
error in ID
The solution is provided in the SAP CSS note :-
#1030077 Cache notification remains in status "started"
i.e.,
" 1) Make sure that the directory specified in the log
exists, and that the J22E administrator-user (usually <SID>adm) has read
and write authorization for this directory."
OR
"2) Change the path for the logs. Enter the required path under 'Server
-> Services -> JMS Provider -> Properties -> Property
'transactionStorePath'.
If there are several server nodes, you must
repeat this step for all nodes. Then restart JMSProvider.
Perform the cache connectivity test, and then check defaultTrace. The
error should no longer be displayed there."

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

N2248 active-active configuration question

I have a pair of 5548s connected as w/ vPC. I have some 2248s which I wish to connect the the 5548 pair in active-active. Each 2248 is connected to one port on each of the 5548s. The 5548 ports are configured as a port channel. vPC display seems to indicate vPC is working. My problem is the 2248s are each online to only one 5548. If I shutdown their port on which they are "online" to the 5548, they switch to "online" on the other 5548. (both 5548 configurations are identical, except for items like switch name.)
How do I config the 2248s to connect via etherchannel to the 5548s, and to thereby come up online to both 5548s at the same time? What am I doing wrong? I'm happy to post configuration if that would help.
/Chris Thomas, UCLA

My problem was the documentation is comewhat unclear on how to configure the 2248s. It is necessary to configure an identical FEX and port-channel on each 5548. The port-channel defs need to have a matching "vpc n" on each 5548. This statement has nothing to do with the vPC domain number, and must be unique for each 2248. Once this is added, the 2248s come up online to both 5548s at the same time. (There doesn't seem to be a command which specifically says that the 2248s are connected in etherchannel mode.) (The vpn n is how vPC knows which ports are associated with each port-channel.)

ACE 30 Module Active-Active configuration

Hi,
We have two ACE 30 module in two Cat 6k with multiple contexts. And our requirement is to have both the boxes active for some context. We have configured the ft vlan, ft peer and ft group for each context on ACE level. And on Cat 6k, L2 vlan is created for ft and mapped with ACE service module with svlvc command. The interface on switch used for ft is configured as Access port with ft vlan. But when we try to do Failover testing by shutting down the upstream link of ACE2, the active context on the ACE2 is not failing over to ACE1. Let me know whether we need to do any additional configuration to achieve this.? . The running configuration is as below,
@ Cat 6K,
Vlan 999
name ft_vlan
svclc multiple-vlan-interfaces
svclc module 2 vlan-group 100
svclc vlan-group 100 201,203, 999
int gi 1/3
switchport
switchport mode access
switchport access vlan 999
@ ACE 30,
ft interface vlan 999
ip address 2.1.1.1 255.255.255.252
peer ip address 2.1.1.2 255.255.255.252
no shutdown
ft peer 1
heartbeat interval 100
heartbeat count 10
ft-interface vlan 999
ft group 1
peer 1
priority 105
peer priority 90

inservice
ft track interface INT-VLAN-203
track-interface vlan 203
priority 100
peer priority 50
ft group 2
peer 1
priority 105
peer priority 90
associate-context Context1
inservice
ft group 3
peer 1
priority 90
peer priority 105
associate-context Context2
inservice
ft group 4
peer 1
priority 105
peer priority 90
associate-context Context3
inservice
Thanks in advance,
Divya

Hello Divya!
It should work assuming the following:
1.) You have a trunk/portchannel between the ACE's will all vlans each context is using including 999 for FT)
2.) You are using bridged mode on ACE or one-armed with on alias. OR you are using routed mode with an alias IP that is used as the server gateway.
Can you login to the admin context on each ACE and issue "show ft group detail" and send it back to the alias? Also, "show run interface"/"show run rserver" from each context would be useful to see the way you have the configuration setup.

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?

Oracle VM 3.1 active active configuration

Hi
I am implementing Oracle VM 3.1 (4 physical servers) in two data centers, we would like to make it active/active, two servers running in a site and other two servers in another site, we would like a single server pool for the 4 servers so VM Guests can be started in both sites.
I can see a problem with the storage (which ideally should be active/active), I think the only options I have is using storage based mirroring to mirror the LUN used by the Guests from one site to another or use a clustered NFS arrays. All 4 servers accessing the one storage arrays located in a site.
Any other options?
Thanks a lot for the help

May I ask what you're trying to accomplish?
What connectivity do you have between the two datacenters?
I don't know what type of replication or etc you're trying to use to mirror the data across data centers/ storage devices....but I don't know if it would work with the repos or not. I imagine it would depend on what tyoe of lag in data you'll have at the peak of your usage. I assume you want to do this for HA?
