  8. 8. Overview: Important Vault Windows Services• Symyx Vault Message Processing Service (VMPS)• Symyx Vault Server 1.0 (SymyxVS10, SVS) • Security Token Service (STS) • RAS • Query Service• Symyx Workflow Service (WFS)• World Wide Web Publishing Service (IIS) • Vault Public Web Service • Vault Private Web Service
  9. 9. Overview: Important Vault Processes
  10. 10. Vault Web Services and Application Pools
  11. 11. Workflow Service Troubleshooting Tips • Symyx Vault Workflow • Common reasons that Service depends on the the Symyx Workflow World Wide Web Service stops or will not Publishing Service start • Requires the Symyx Vault – Dependent services not running Message Processing – Configuration issue Service to enroll new – Port conflicts documents in workflow – No database connection
  12. 12. Vault Message Processing Service Troubleshooting Tips • Symyx Vault Message • Common reasons that Processing Service the Symyx Vault depends on the following services Message Processing Service stops or will not – Symyx Vault Server 1.0 start (RAS, STS, Query service) – World Wide Web Publishing Service – Other dependent – Workflow service to enroll services are not running new documents in – Configuration issue workflow – No database connection
  13. 13. Vault Server 1.0 Service Troubleshooting Tips• Symyx Vault Server 1.0 Service is NOT dependent on another service• Check status pages for RAS/STS to verify that services are running RAS STS
  14. 14. Vault Public/Private Web Service Troubleshooting Tips• Vault Public/Private Web Service are dependent on World Wide Web Publishing Service (IIS)• Check status pages for public/private web service to make sure that these services are running Public Private
  15. 15. Detecting Common Vault Server Issues• Multiple log files created with the same timestamp• Memory consumption of a process staying at 800 MB to 1.2 GB or higher for any length of time• Win32k memory error messages recorded in the log files• Authentication issues after month of successful logins• Message Queues message count grows consistently throughout the day• Status pages for the different services show up with an error• Windows Application Event log is full of Vault Message Processing Service restart messages
  16. 16. Best Practices for Vault System Management• Restart middle tier servers every 30 days or after each operating system update (per Microsoft) – Automate by using Windows scheduled tasks or your network management platform• Archive Vault and Tomcat logs every 30 days – Automate by using Windows scheduled tasks or your network management platform• Restart all Vault services weekly – Automate by using Windows scheduled tasks or your network management platform• Check disk fragmentation once a month – If fragmentation levels are consistently higher than 30% when defragmented monthly reduce the time to weekly• Review Windows application and system event logs every 60 days for errors and correct as needed• Integrate with existing network management environment for advanced service monitoring
  17. 17. Microsoft Message Queues (MSMQ)• Vault Message Processor manages asynchronous processing of Vault Objects via Microsoft Message Queues
  18. 18. Message Handlers Message Handler Description FullTextIndexer Adds any text provided by VO to the full text index VaultObjectIndexMessageHandler Indexes any Property Set Definition (PSD) data (including structures and reactions) PropertyIndexMessageHandler Indexes VO core properties to support Standard Search. These indexes are also used by Vault for internal querying (resolve assemblies, for example). WorkflowActivator Enrolls items in workflows based on the active workflow associations WorkflowTransitionMessageHandler Indexes workflow stage value after transitions PropertyExtractionMessageHandler Extracts data from properties designated for display in Notebook Explorer (new in 6.7)
  19. 19. MessageHandlerStatus Table: Status Tracking State Meaning Queued Vault Object (VO) is currently queued for processing by the message handler Processed VO was processed by the message handler Failed VO could not be processed by the message handler Requeued VO has been submitted to the handler by the RequeueVaultObjects utility Ignore VO is not subject to status tracking Unknown VO has not been processed by the index status tracking feature
  20. 20. RequeueVaultObjects.exe Arguments Examples: • Re-queue failed VOs in the Site repository RequeueVaultObjects -repository Site • Re-queue queued VOs for full text indexing in the R&D repository RequeueVaultObjects -repository "R&D" –status Queued –queues FullTextIndexer • Re-queue untracked VOs Process Chemistry repository RequeueVaultObjects -repository "Process Chemistry" –status Unknown Argument Description Required Default -Repository The repository that will be acted upon Yes N/A -MessageLimit Maximum # of messages that will be created No 100000 -Status The message handling state to be queued No Failed -Queues List of queues to populate No All
  21. 21. Automation Support with Windows Task SchedulerStatus tracking and RequeueVaultObjects utility enables automation of messagehandling management activities with the help of Windows scheduled tasks• Large re-queuing Jobs can be split across several load-balanced servers – Strategy 1: Schedule re-queuing jobs against a large set of messages during long periods of time with low system activity (nights and weekends) – Strategy 2 (Recommended): Constantly “trickle” relatively small numbers of messages at regular intervals around the clock• Example: 1 million Vault objects to reprocess with two load-balanced Vault Servers – Scheduled job on Server 1: Re-queue 5000 objects on each full hour – Scheduled job on Server 2: Re-queue 5000 objects 5 minutes after each full hour
  22. 22. Monitoring Thresholds • “Vault Monitoring Guidelines” – Recommended thresholds and alert states – Includes example jobs that can be installed on your Vault servers – Standalone monitoring – Network management integration • Part of 6.7 Administration Guide • Contact Accelrys Support to obtain a copy for v6.6
  23. 23. Leverage Windows Server 2008 Event Viewer• Utilize the new feature to create a new scheduled tasks directly from within Event Viewer based off of specific events recorded in the logs• Respond to events in three ways: – Start a Program – Send an E-mail – Display a Message
  24. 24. Leverage Windows 2008 Data Collector SetsData Collector Set: – New feature added in Windows Server 2008 – Organizes multiple data collection points into a single component – Outputs HTML reports which can be sent to support for troubleshooting – Can be configured to generate alerts when thresholds are reached – Use out-of-the box System Diagnostics/Performance report or create your own customized reports – Scheduled task can be set up to Run Data Collector Sets at regular intervals – Caution: Collecting performance and system information can affect overall system performance!
  25. 25. Leverage Windows 2008 Data Collector Sets
  26. 26. Managing Vault from Single Directory (Symbolic Links)• Manage your Vault configuration files from a single directory – Create folder junction links to Vault and Tomcat logs – Create file hard links to all configuration files• Directory can be shared out and accessed from a single management machine – e.g. manage several load-balanced Vault Server from one computer
  27. 27. Summary• We reviewed Vault service monitoring points and examined monitoring solutions that can run standalone or be integrated into an enterprise management system• Special thanks to the monitoring guidelines author: Chuck Collins, Advisory Software Test Engineer• Resources – Notebook IT/Admin forum on the Accelrys Community • Email support@accelrys.com to join• How to contact Accelrys Support – Email support@accelrys.com – Accelrys community (https://community.accelrys.com)
