Scheduling a task

, ,
1

I am new to Software AG webMethods, and am evaluating it for a series of integration scenarios. I installed webMethods (The latest evaluation version) on an Oracle Virtual Box VM with Windows Server 2012 R2.

I want to schedule a task that logs “test 123” to the Server Log on a 10 second interval. I created new Flow Service in Software AG designer 9.6, after creating a new Package. I placed a pub.flow:debugLog sub-task/command in the Tree View of the Flow Service. I created a text input and ran it from the right-click menu after setting my message under → Run As → Configuration.

At this point it logs to the Server Log. The problem I now have is to schedule it. I went to the admin console on localhost:5555, selected Scheduler and clicked on Create Scheduled Task.

I filled in the form with my service details. I then clicked on “Save Tasks”, and it showed me a blank error message.

It logs this in the server error logs:

Could anyone please give me some pointers?

Under Settings → JDBC-Pools, check for the function “IS Internal”, if this is working.

The scheduled tasks are stored in the database table IS_USER_TASKS.

I am not quite sure how the trial version is configured at that point.

IS there a way to check last modified date of a “Scheduler Task”

Thanks,
Madhu.

Hi Madhu,

you will have to introspect the table IS_USERS_TASKS in the useer/schema which contains ISInternal schema component.
Look for a column named INSERTTIMESTAMP or similar.

I doubt if you could capture this info OOTB as IS_USER_TASKS table does not have Audit-Date-Time-Stamp, even security logs does not show anything if you update the scheduler settings.

I think you have to build some custom logic around IS_USER_TASKS but this is not recommended approach and might be risky.

Provide more details on your requirement, why you need to check the last modified date?
