nice work , can otd supplemented with other lb's like big ip /ohs

In the past I've done this with OHS and mod_proxy / proxy_balance. You can work with other lbrs.
BTW, thanks...

thanks for great article!

Thank you! Good to know OTD is supported on another platform. Regards!

On OHS/Apache, it should be something similar to this:

--------------------------------------------------------------------------------

<VirtualHost *:7777>

    ProxyRequests off

    ServerName services.parisi.spo

    <Proxy balancer://apibalancer>

        BalancerMember http://vmoag01.pub.parisi.spo:8080

        BalancerMember http://vmoag02.pub.parisi.spo:8080

        # Security

        Order Deny,Allow

        Deny from none

        Allow from all

        # Balancer Settings

        ProxySet lbmethod=byrequests

    </Proxy>

    <Location /balancer-manager>

        SetHandler balancer-manager

        # Security

        Order Deny,Allow

        Allow from all

    </Location>

    ProxyPass /balancer-manager !

    ProxyPass / balancer://apibalancer/

</VirtualHost>

Hi Marcelo,

Good article. I was wondering if it's possible to "environmentalise" Business Services as I couldn't find a way to do so. I'm pretty sure that in most cases when promoting a Policy across environments, the endpoint of the exposed service and it's WSLD will change. How would you manage this? would you have to go into Policy Studio and reload from WSDL URL manually?

Thanks,

Marc

Hi Marcelo - qq,

• We are scaling the integration layer where interface volume will increase.  We also need to do reconfiguration of some of the existing interface policies in order to begin isolating some of the traffic so it can handle the volume.  How do you determine the impact of scalling the OAG layer? Is there any standard template available for such a effort ?? or OAG scale out is pretty much straight forward with minimum efforts in policy migration ??

• Do we need to build some additional v-servers & reconfigure some of the existing interface policies to isolate the trafic in order to handle the volume?  What additional efforts are needed for the install, config & OAG policy migration?  Is the reconfiguration needed in both source & additional servers?

Thanks

Hello Marc,

I am not 100% sure about the answer, as I am more the kind of "infrastructure" guy. I don't do too much the functional part (policies, etc...), but have you looked at Configuration Studio? I think this is the tool you are looking for, as it is used to promote policies and circuits across different environments (dev, test, prod...).

Thanks,

Hello

For the 1st question, from my understanding OAG scaling is pretty straight forward. Just make sure you deploy the policies across the nodes so that you achieve consistency on your "group". I don't know about any template available for this.

In this case, I think the best thing to do in this case is test. Performing tests, you'll be able to determine if your actual environment can handle everything, or if you need to create new v-servers. Also, test both scenarios: isolating the policies, and putting them all together.

Thanks,

Marcelo

Marcelo - Thanks for your reply. Expansion is for Production environment. If we need to define the estimates now how could we determine the capacity with increase in number of transaction volume and we can't really do performance testing in production ?? Also are there any benchmark results wrt to OAG capacity expansion ??

Thanks

Anish,

Try setting up a "load" or "test" environment for this. You should not perform load tests in production. Best way is to setup an environment like production, and try to perform the load tests in this environment.

As a consultant, I don't have information about benchmark results because I don't usually work with capacity planning and sizing. This question should be addressed to the product team, sorry.

Marcelo

Hi Parisi,

I did look at Config Studio and it allows to create an environment deployment package based on what elements of your configuration you've "environmentalised", but the parametrising of the config needs to be done from the Policy Studio.

A colleague of mine mentioned that we might achieve this from within the property but I haven't had time to actually check it out.

Thanks,

Ok. I am not sure as I told you. Another place you might wanna take a look is at sample scripts in API Gateway installation directory. Maybe you can write something that automatically changes the endpoints according to the environment.

Please let me know how you worked this out.

Marcelo

Hi Marcelo,

This is what my colleague said but I haven't tested it yet:

"...When you add the web service in policy studio then it will auto-create a policy for you. If you go into that policy and open the service handler up then you will be able to change the routing details. The default is 'Use the WSDL of the back-end Web Service' but if you select 'Override...' you can then select the environmentalize..."

Yes, that way I know. But, what if you change the wsdl on development, for example, for a fix or new version?
