  1. WV Object Cell Supporting in R11

  2. Acknowledgements • Sal Lazzaro

  3. What and Who • What is the WV object cell? • Mechanism for querying the Worldview repository and distributing the results to clients either through a web service (Tomcat). • Through web service -- remote client • Directly -- direct client • a separate process communicating with DNA via Java RMI. • Who uses the WV object cell? • Unicenter Management Portal (UMP) • Worldview Reporting Service (WRS) • Unicenter Configuration Management (UCM) • Enterprise Management (EM) • Advanced Systems Management (ASM)

  4. Architecture -- Overview DIA Services Cells Agent Cell DSM Cell WV Cell EM Cell Clients (Both Remote and Direct) UMP WRS EM AMS UCM

  5. Architecture – Remote and Direct Clients Remote Client Web Services request Web Service Application Server (Tomcat) MDB DIA Client DIA Request DIA Knowledge Base (has grid info) DIA Request DNA WV Cell Direct Client Wv_WSAPI WV API Sevpropcom SpcInterface

  6. Architecture UKB Service DNA Service Sevpropcom Service wvobjectcell.exe (JAVA Binary) Via JNI UMPInterface.dll WV_WSConnectionPool.dll Wvobjectcell.dll UnicenterDeployment.dll WV_WSAPI.dll SPCInterface.dll

  7. Install Location • Wvobjectcell.exe: • Program Files\CA\Shared Components\CCS\DIA\dia\dna\bin • Wvobjectcell.jar (renamed to exe) • Launched by DNA Service • All other wv cell DLLs: • Program Files\CA\Shared Components\CCS\WVEM\Bin • Loaded by wvobjectcell.exe (via JNI) • SPCInterface.dll: • CA_APPSW • Linked with wv cell DLLs

  8. Logging • Logging through DIA: • CCS\DIA\dia\dna\config\cell.cfg • Set LOG_LEVEL parameter • Possible values: • OFF • SEVERE • WARNING • INFO • CONFIG • FINE • FINER, • FINEST • ALL

  9. Logging (Cont’d) • Log files will be in: CCS\DIA\dia\logs • Log file names: • Wvobjectcell_java#.log • Where # is from 0 to 3 • Contains output from wvobjectcell.jar • Wvcell_native#.log • Where #3 is from 0 to 3 • Contains output from wvobjectcell.dll • Wvcell_registration#.log • Contains output from the registration services

  10. Logging (Cont’d) • Other wv cell logging: • Create system registry key: • MyComputer\HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\CA-Unicenter/TNG\Worldview\WVCell\wvcell_log = 1 • Log files in DIA\dia\dna directory • connectionlocks.log (from WvWs_ConnectionPool.dll) • Wvwsapi.log (from Wv_WsAPI.dll) • WvRegistration.log (from UnicenterDeployment.dll)

  11. WvObjectCell Overview • 3 Types of client interactions: • Get • Client receives information from the database • Set • Client updates information in the database • Push Technology • Client subscribes for notifications and is called via a callback function when an event that is subscribed for occurs
