NetDRMS Release Notes

Version 2.7

Significant changes since Release 2.6

• To better balance work load, the SUMS server program, sum_svc, has been replicated. The result is a set of server programs instead of just one. Each one handles one specific SUMS API function call (e.g. SUM_get()).
• Two (required) parameters have been added to the local configuration file to support the Multi-SUMS features: SUM_NUMSUM, SUM_MAXNUMSUM. The first sets the initial number of sum_svc processes started, and the second the maxiumum number that can be running. SUM_MAXNUMSUM should be between 1 and 8 (it cannot exceed 8), and SUM_NUMSUM should be between 1 and SUM_MAXNUMSUM. Also, the parameter SUMS_MULTIPLE_PARTNSETS has been added; it should be set to 1 if there is more than one set of SUMS disk partitions to which data from data series in different storage groups can be assigned
• The DRMS library prevents module code from adding new records to a series if there is a summary (aka "shadow") table associated with that series. This change is in preparation for a future, larger change whereby queries will take advantage of summary tables to optimize database queries.
• unpublish_series.sh was ported to a perl script (unpublish.pl) that can be run in the background. unpublish_series.sh cannot be run in the background. Due to periodic long run times, this script needs to be run in the background.
• Numerous bug fixes

Known Bugs

• The Makefile in the sample proj/cookbook directory does not work with the release if the configuration parameter SUMS_TAPE_AVAILABLE in the config.local is set to 0. This will be fixed in the next release. Meanwhile, a workaround suggested by R. Burston is to modify the Makefile as follows: Add (before the .SECONDEXPANSION: line)

  include $(DRMS)/localization/custom.mk
  ifneq ($(CUSTOM_DEFINES),)
  CCFLAGS := $(CCFLAGS) -D$(CUSTOM_DEFINES)
  endif
  

NetDRMS 2.7 is a subset of JSOC Version 5.14, q.v.
