Error description

  • With systems where there are a lot of users with large mail
    files being synched to the device may cause high CPU and slow
    performance because of how the Lotus Notes Traveler NTSDB was
    organized.  This APAR improves several of the queries for
    finding documents that need to be synched to device,
    
    Also included in this APAR is the new tell command to get some
    db usage information
     Tell Traveler DBUsage help
        DBUsage  - Display usage statistics from the Lotus Traveler
    database.
    

Local fix

Problem summary

  • Customer reported seeing frequent high CPU and performance
    problems running Lotus Traveler.
    

Problem conclusion

  • The issue was tracked to not the number of servers, but the
    number of documents each user was syncing.  Syncing a large
    number of documents ( 20000+ ) the internal database was seeing
    performance issues with standard db queries.  The Lotus Traveler
    server has updated these queries to be more efficient for large
    data sets.
