condor_convert_history
condor_convert_history(1) General Commands Manual condor_convert_history(1)
Name
condor_convert_history Convert - the history file to the new format
Synopsis
condor_convert_history[-help]
condor_convert_historyhistory-file1[history-file2...]
Description
As of Condor version 6.7.19, the Condor history file has a new format to allow fast searches backwards through the file. Not all queries
can take advantage of the speed increase, but the ones that can are significantly faster.
Entries placed in the history file after upgrade to Condor 6.7.19 will automatically be saved in the new format. The new format adds infor-
mation to the string which distinguishes and separates job entries. In order to search within this new format, no changes are necessary.
However, to be able to search the entire history, the history file must be converted to the updated format. condor_convert_historydoes
this.
Turn the condor_schedddaemon off while converting history files. Turn it back on after conversion is completed.
Arguments to condor_convert_historyare the history files to convert. The history file is normally in the Condor spool directory; it is
named history . Since the history file is rotated, there may be multiple history files, and all of them should be converted. On Unix plat-
form variants, the easiest way to do this is:
cd `condor_config_val SPOOL`
condor_convert_history history*
condor_convert_historymakes a back up of each original history files in case of a problem. The names of these back up files are listed;
names are formed by appending the suffix .oldver to the original file name. Move these back up files to a directory other than the spool
directory. If kept in the spool directory, condor_historywill find the back ups, and will appear to have duplicate jobs.
Exit Status
condor_convert_historywill exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure.
