BE/CO work (2/3) • The new version of japc-monitoring become PRO -> 3. 4. 0 – – – • The version PREVIOUS -> 2. 32. 0. Here are the changes/bugfixes from 3. 0. 0 -> 3. 4. 0 • [JMON-525] - Throw Subscription. Runtime. Exception from start. Monitoring/stop. Monitoring to allow clients to handle it. • [JMON-522] - Wrong configuration saved in the Configuration. Loader • [JMON-523] - Wrong method call to get the parameters from the configuration • [JMON-524] - Problem with DBAlarm. Resolver test after changing the dev db. • [JMON-521] - NPE when giving a uncomplete Parameter. Descriptor to add. Parameter method: • - provided more checks for a Parameter. Descriptor fields correctness. They have to be filled in now. • [JMON-519] - Set ignore. First. Update to false and ignore. Cycle. ID to true by default in the japc-mon 3. x. x • [JMON-520] - NPE when adding parameter with converter bean id. • [JMON-514] - Parameter. Descriptor. Builder does not return itself from add. Module() method. • [JMON-513] - Add 'hold. Last. Value' attribute the jmon Please notice that currently if any of the subscriptions cannot be started during the startup of the application the Subscription. Runtime. Exception will be thrown. This should be handled properly by the clients. Usually a catch is enough where you decide what to do (continue or exit the application? ). This allows for more fine-grained control of the subscriptions. Release LSA for LHC/SPS with changes to allow publication of Trims – i. e. every time some trims a parameter, a notification about that will be sent via JMS. This is so that applications can subscribe to it and avoids pulling settings with high frequency just to verify whether they have changed or not. 30 Aug 11 P. Charrue - BE/CO - LBOC 3

BE/CO work (3/3) • The OASIS team will use this technical stop to try to find the route of a recurring problem which is somewhere between oasis server, JMS broker and oasis clients. It is easy to reproduce by restarting oasis-server. • The timing team will introduce a new rule in the Sequence Manager to avoid to send new hardware settings in the CBCM if all CPS cycles are not mapped on LSA cycles. • The CMW/RBAC team will: – New PRO release of cmw-rda v. 2. 9. x Java library RDA • The major changes introduced in this release (2. 9. x): • 1. New, improved Array Calls API, which handles properly context information for each parameter. • 2. Improved re-subscription mechanism – better handling of exceptional conditions on FEC server. • 3. New, improved configuration for Jac. ORB (CORBA implementation), which fixes “in-famous” blocking issue • 4. + many minor bug fixes. . – Upgrade of all Proxies (LHC & Injectors) • new version of CMW Logging library • integration with new CMW Tracing service • additional diagnostics for established subscriptions • code cleanup – Upgrade of RBAC A 1 servers • improved db access code • improved error reporting for authentication failures 30 Aug 11 P.
