Rational RTC and Oracle on AWS cloud


Kent Roberts (11) | asked Feb 22, 11:10 a.m.

 Our IT department is moving all the Oracle services from in house servers to the cloud. This includes the Oracle Database that serve our Rational Tools applications.


We have been prototyping this change on  sandbox servers for Jazz, RTC, RQM, RM and Data Warehouse. 
 
We have been able to move the DB from the in house servers to AWS cloud and all seems to function, however the RTC diagnostic for the Database fails because the performance measurement is 4500 ms, way above the 2500 ms allowed. The performance before the change to AWS cloud was 45 ms.

We have also did  a " repotools-rm -reindex all" of the Requirements Management DB indices and what  took 10 minutes with the in house DB now takes over 90 with the AWS cloud.

The AWS cloud DBA says that all looks normal on his side and suggests that we move the entire RTC installation, not just the Oracle DB, to the cloud.

My question is, has anybody have this kind of setup, RTC applications running on in house servers with the DB on the cloud?

Thanks

There needs to be low latency between the jazz applications and the database

I would definitely not run this setup for production - there's just too much variability in an external Internet connection to a DB in the Cloud.

I set up and maintained a full CLM set up in the AWS environment for one of my clients for several years. They used the SQL Server RDS as the back end database service, and a series of VMs with each of the Jazz apps deployed and it worked really well.

It wasn't a full enterprise environment - they were focussed on Quality Manager, so I ended up having one VM specifically for the QM application, one VM for the rest of the applications, and one VM for the reporting components (DCC, RB and initially LQE but then we turned that off as they really weren't using it).

We also set up a VM running AD for their LDAP, and had a CLM web proxy defined using the AWS appliances.

It was pretty seamless really, if not expensive. If IBM's SaaS offering was available at that time, I would definitely have recommended that instead.

 Thanks for the comments.

We are now looking into other solutions including moving all our Rational tools to the cloud.
