Re: [Architecture] [BPS] Creating a new UI page with a retry mechanism for failed BPEL activities in BPS
HI Hasitha, You mean adding another filter to filter out the instances which can be retried with each instance raw having another link with retry option ? I think it would be easier from a user's point of view to have another page Retry Failed Instances with the filtering options that are available in the current instance view. That way, user can directly go to that page and filter instances to retry. It can like a task list to an maintenance user.

We can introduce new tab similar to status filter [1] for filtering. 2. Since this is an admistrative task, we can introduce new Instance Management page as well. I think, 1st one is more suitable,, because literally this page shows instances in state Active with Failed activities.

This is a part of the issue: A mechanism to recover failed activities when ODE events are disabled [2]. In WSO2 BPS, retry mechanism for failed activities is provided via the BPEL instance view when the BPEL activityLifecycle events are enabled. But when the events are disabled, there is no way to retry failed activities using management console. As a solution for this issue, a retry mechanism for failed activities has been added per each process instance by Hasitha. The current requirement is to create a new UI page displaying all the failed activities with a retry mechanism. Since this will be added to the product management console as a new page, under which category should it be added in the menu panel? Any feedback/suggestions on this matter would be appreciated.

Re: [Architecture] Default version number when switching the build to released versions of jars
Changing group names will be lot of work? Thanks, Samisa...

Re: [Architecture] Meeting Note : Implement a Pluggable Version Strategy feature in APIManager
Hi Dinesh, On Tue, Jan 13, 2015 at 11:11 AM, Dinesh J Weerakkody dine...@wso2.com wrote: Hi All, I have tested the above proposed method with a fresh APIM 1.8 pack. We can successfully create and invoke APIs as follows. [image: Inline image 1] Here what we do is simply add the version number to context. Also I have removed version from the resulting synapse api xml file (smiler to default version) otherwise we have to send version number after the context (Ex: http://localhost:8280/1.0.0/docman/*1.0.0*/add). Now we can invoke this API as follows since context is matching to request url and this is default version. http://localhost:8280/1.0.0/docman/add With the above solution system doesn't allow us to create a new version of the API. Currently synapse doesn't allow to use deferent contexts with same API name. Ex: Name : DOCMan Context : */1.0.0/docman* Version: 1.0.0 Name : DOCMan Context :* /2.0.0/docman* Version: 2.0.0 We used a template as a context to overcome this situation. [image: Inline image 2] With this solution context will be same among all versions. We resolve the context template when API is initializing in synapse runtime. There is another issue came up with this solution. Synapse doesn't allow to use version attribute in API xml without a version-type (version strategy) attribute. URL is the only value that we can use with the version-type attribute and when we invoke api we must send version after the context if we use URL as the version strategy. We can introduce a new version strategy to overcome this situation. For the time been I have disabled the validation. After above mentioned changes we can successfully deploy multiple versions of the same API. But when we try to invoke the APIs we faced another issue. When the request comes to APIM side there is a problem in authentication handler. We use context to check whether access is granted to the given token or not. In APIM side tables we have context template but in runtime we send resolved context. So there will be no matching access grants and request will be rejected. We have two solutions to overcome this issue. - Have a separate column in APIM database to store the resolved context (Use in runtime) - Add a new attribute to RXT to store context template (This is used to display the context template in UI when editing the API) I think that the second option is better than adding new columns to the tables. Please share your suggestions or thoughts on this. When storing the context in APIM DB, I think you have to keep the resolved context not the structure of the context. Having the resolved context in AM_API table will allow validating the key with a single SQL. As you have identified, it would be enough to keep the structure of the context only in RXT. No additional columns are needed on AM_API table. Thanks *Dinesh J.

Context = /api/{uri.var.version}/anytext Version = 1.0.0 Then we generate the context path based on a the template when creating the synapse xml and use default version-type (empty). *Current version* api xmlns=http://ws.apache.org/ns/synapse; name=admin-API context=/api” version=1.0.0 *version-type=url* *Proposed version* api xmlns=http://ws.apache.org/ns/synapse; name=admin-API *context=/api/1.0.0* version=1.0.0 Please note that version appended to context while version tag keeping as it is. If user does not include the {uri.var.version}, current process will be used. Ex: context=/1.0.0/api context=/gov/1.0.0/api context=/gov/1.0.0/api2 *Option 2 : Match APIs based on configured context pattern* api xmlns=http://ws.apache.org/ns/synapse; name=admin-API context-pattern=”{uri.var.context}/{uri.var.version}” context=/api” version=1.0.0 version-type=url Ex: {uri.var.version}/{uri.var.context}= http://localhost:8280/1.0.0/api {uri.var.context}/{uri.var.version}= http://localhost:8280/api/1.0.0/ In synapse level we have to uniquely identify a API with the context and version. With second option, it will be difficult and can be lead to conflicts If user define an API with context=”1.0.0” version=”api” while having an API with context=”api” version=”1.0.0”. So we have decided to drop the second option and throughly test the first option. Please share your suggestions or thoughts on this.
