Workbench Release Notes

Workbench 9.0.0.66

  • 8119: Fixed a Check for Updates… bug that prevented Windows users from upgrading Workbench 8.1.2.1 to Workbench 9.0.0.66. The workaround is to download Workbench 9 from the Method R downloads page.
  • 8071: Rearranged the mrskew manual page to make the packaged .rc files section easier to find.
  • 8067: Fixed a bug causing the Workbench application not to check for updates upon startup in cases when it should.
  • 8066: The Workbench application for Microsoft Windows now resists accidental concurrent instantiations of the same version.
  • 8063: New mr1011 utility converts Oracle Database version 10.2 trace files into version 11.1 format, which enables Method R Workbench to process 10gR2 trace files.
  • 8060: mrprof now processes all data in a multi-session trace file; the –ignore-multiple-sessions and –ignore-multiple-sessions-file options have been eliminated.
  • 8059: New column names and tool tips in the files pane make it easier to understand your data.
  • 8054: Added new mrwhen reports to the actions pane.
  • 8053: mrprof now writes output printed by the –trace option to a file called *.trace.
  • 8046: Fixed a bug causing Workbench not to open the output HTML file when using the mrprof –trace option.
  • 8044: Major advisory text improvements throughout the Method R Profile report.
  • 8041: Fixed a bug that caused the Workbench application to make too many check-for-updates calls.
  • 8038: Added “RTs” column, which shows the file’s network round-trip count.
  • 8025: Workbench on macOS now automatically detects both JRE 8 and JDK 8.
  • 8021: Workbench now writes the Java home directory and version number information into the application log file.
  • 8016: Optimized mrprof memory allocation for cases in which the input trace file has many thousands of distinct SQL texts.
  • 8013: Fixed a bug where mrprof would fail to record why it could not load an extremely large XML file.
  • 8000: Workbench now uses parallel execution to load trace files into the files panel. This reduces file load response times on multi-core systems. The degree of parallelism is configurable in Preferences › Profiler › Workbench Parameters › Use this many parallel profilers.
  • 7995: Renamed “Report Parameters” dialog to “Action Parameters”.
  • 7994: Field labels in the “Action Parameters” dialog now use sentence case.
  • 7992: Made cosmetic improvements to the “Action Parameters” dialog.

  • 7988: Alphabetized the action name list in the application’s actions pane.
  • 7987: The “Action Parameters” dialog now has field hints to help with more complicated input formats.
  • 7985: Created new manual page for mrworkbench, which includes JRE troubleshooting advice.
  • 7983: “Action Parameters” dialog now remembers the most recent value you’ve used for each parameter during a given invocation of Method R Workbench.
  • 7974: Removed the unimplemented –compression-formats option from the mrprof man page.
  • 7969: Fixed a bug that can cause mrprof to re-profile input files more often than necessary.
  • 7954: mrprof now makes it easier to see hierarchical relationships in Profile by Cursor and Execution Plan sections, by using numbers instead of dots to denote hierarchy levels.
  • 7952: Fixed a bug that would cause mrprof to print all the execution plans for a given statement in each section 4.*.5.*, instead of just one plan per section.
  • 7946: Removed “can’t evaluate” message explanation from the Exit Status section of the mrskew man page. This message no longer applies to the newly rewritten mrskew utility.
  • 7938: Changed mrprof –ofile %s specifier to %b (because it represents the file base name), which is consistent with the syntax of the new mrcrop utility.
  • 7934: Fixed a bug that in which mrprof could die instead of issuing a warning.
  • 7932: New Preferences › Profiler › Workbench Parameters › “Auto-open HTML when loading one or two files” option replaces the old and less useful “Open up to this many HTML files per load” option.
  • 7908: References to undefined variables formerly caused mrskew to emit an error and die. Now, the value of an undefined variable reference is the empty string, and mrskew will not throw an error.

  • 7902: Fixed an HTML validation error.
  • 7901: Added execution count to the Profile by Cursor section.
  • 7899: Added execution count to the Profile by Caller sections.
  • 7898: Added execution count to the Profile by Statement sections.
  • 7892: mrtimfix is now obsolete and no longer shipped. mrtimfix was useful only for systems prior to Oracle Database 11.1 (which we no longer support), and 11.1 systems suffering from Oracle bug 7522002 (which was patched long ago).
  • 7891: mrtim is now obsolete and no longer shipped. It is replaced with the much more useful mrwhen.
  • 7886: A new horizontal scroll bar makes it easier to use all the new columns in the application’s files pane.
  • 7883: Documented how mrskew uses the PERL5LIB environment variable.
  • 7870: Renamed mrskew –glabel and –slabel options to –group-label and –select-label.
  • 7860: New mrskew $base_name and $dir_name variables make it faster and easier to reference parts of a file name.
  • 7851: Created a manual page for mrprofk.
  • 7838: Improved the advisory text in the Profile report for synthetic calls, and improved Synthetic Calls documentation in the mrprof manual page.
  • 7833: Eliminated the –eula option. Users can find the license agreement information in each utility’s manual page.
  • 7828: Standardized the processing of options used by every utility. Now, –help, –license, –man, and –version all behave consistently, and command line errors are processed consistently across utilities.
  • 7813: Fixed a bug that would spin the application’s “Processing” busy indicator forever when a command line option’s quotes don’t match.
  • 7803: Removed mrskew –timunit, –cpuunit, and –trcunit options and the $cpuunit and $timunit variables.

  • 7799: Consolidated and simplified error reporting for .rc file names not found.
  • 7798: Deprecated mrskew –rc=mrnl.rc. To see when calls begin and end, use the new mrwhen utility.
  • 7796: Changed the XML schema for reports.xml so that now label is an attribute of the diagnostic element (instead of a child element).
  • 7788: Method R Workbench now uses LaTeX to render more beautiful PDF manual pages.
  • 7784: Moved mrls START-TIM and END-TIM columns to a more logical place in the output.
  • 7782: mrls –debug option now writes debugging information to stderr.
  • 7781: Renamed mrls TIM0 and TIM1 columns to START-TIM and END-TIM.
  • 7780: New mrls –tags-dbfile option allows you to specify which SQLite database to use for retrieval of TAGS information.
  • 7777: New mrls –include=:all and –exclude=:all options obviate the old –none and –details options.
  • 7775: Added new mrls STATUS column values.
  • 7774: Replaced the old mrls options like –cpu and –nocpu for including and excluding columns with new –include and –exclude options.
  • 7772: The mrls –sort option now takes a column heading (e.g., DURATION, SIZE, VERSION, etc.) as its argument.
  • 7763: mrls now dies if you use –sort on a field and then exclude that field from the output.
  • 7762: mrls is now more than 20× faster than before.
  • 7759: Deprecated the mrls –scanmax option; to request full-precision output, use –include=DEP or any of the other columns that force mrls to read the entire input file.
  • 7755: Reduced the size of the distribution by storing the sqlite3 load library in the distribution’s file system instead of the sqlite jar file.
  • 7752: Made significant, sweeping changes to mrls column display interface and manual page.
  • 7746: mrls now displays “?” instead of negative number for unknown recursive depth values.
  • 7739: mrls no longer uses a complicated algorithm based on the file’s modification time to try to guess the START value for a file. Now it simply warns when there is no timestamp in the input trace file.
  • 7737: Removed under-utilized mrls options: –trcunit –timunit –cpuunit –precision –human –dformat –tformat –units
  • 7722: Now you can use mrls -r as an alias for mrls –reverse.
  • 7719: Documented in mrprof man page that mrprof works only with extended SQL trace files generated by Oracle Database 11.1 and newer.
