Release Notes
|
|The following improvements have been made to the warehouse server
|for FixPak 5:
|
- |Updating configuration parameters
- |The server will no longer update critical configuration parameters such as
|service names to an empty string.
- |Message DWC7906 updated
- |Message DWC7906 now contains names of predecessor steps when reporting
|dependency problems.
- |Trace changes
- |Extra low-level (level 5) tracing was added in FixPak 4 for Data Warehouse
|Center control database access. Normally, this trace is turned on only
|when requested by IBM service. In FixPak 5, the server will only output
|the new control database trace when DDD trace level is set to 5.
|
|The following improvements were made to the warehouse server for FixPak
|4:
|
- |Error on agent shutdown (rc = 7170), secondary rc = 6106.
- |This error occurred when the agent was shutdown before the server sent a
|shutdown request. This error was reported unnecessarily and will no
|longer be reported.
- |System Message and Comment written to log file
- |When a user-defined program has finished running, the System Message and
|the Comment will be written to the warehouse log file. These messages
|are now visible from the Work In Progress display window.
- |Incremental commit now works correctly
- |If an error occurs when a step is populating a target database and the
|value of Incremental commit is greater than 0, all of the results that were
|committed prior to the error will appear in the target database. Prior
|to FixPak 4, partial results were deleted.
- |Unable to run warehouse server after changing trace level error corrected
- |The warehouse server retrieves the name of the logging directory from the
|system environment variable, VWS_LOGGING. If VWS_LOGGING is missing, or
|points to an invalid directory name, the TEMP system environment variable is
|used instead. If TEMP is missing, or points to an invalid directory
|name, the logger trace files are written to c:\. This corrects an
|error in versions prior to FixPak 4 that was caused by the retrival of an
|invalid logging directory name from the registry.
- |Additional support for commit commands in stored procedures
- |The warehouse server sends a commit command to the agent after
|user-defined stored procedures have run.
- |Sample Contents enhanced
- |The warehouse server no longer has to wait for an agent shutdown message,
|so Sample Contents runs more efficiently.
- |The size of trace log files can now be controlled
- |You can now control the size of a trace log file using the new system
|environment variable, VWS_SERVER_LOG_MAX. If you set the value of
|VWS_SERVER_LOG_MAX to greater than 0, the warehouse server will stop enlarging
|the log file when it reaches the a size that is approximately equal to the
|number of bytes indicated by the value of VWS_SERVER_LOG_MAX. When the
|log file reaches the maximum size, the newest trace log entries are retained
|and the oldest entries are overwritten. When doing extensive tracing,
|VWS_SERVER_LOG_MAX=150000000 (150M) is a reasonable size.
