Description

14       As  of  Condor version 6.7.19, the Condor history file has a new format
15       to allow fast searches backwards through the file. Not all queries  can
16       take advantage of the speed increase, but the ones that can are signif‐
17       icantly faster.
18
19       Entries placed in the history file after upgrade to Condor 6.7.19  will
20       automatically  be saved in the new format. The new format adds informa‐
21       tion to the string which distinguishes and separates  job  entries.  In
22       order  to search within this new format, no changes are necessary. How‐
23       ever, to be able to search the entire history, the history file must be
24       converted to the updated format. condor_convert_historydoes this.
25
26       The  condor_convert_historycommand  can also be used to reconstruct the
27       new format in a history file that has been corrupted  or  concantenated
28       with another history file.
29
30       Turn  the  condor_schedddaemon off while converting history files. Turn
31       it back on after conversion is completed.
32
33       Arguments to condor_convert_historyare the history  files  to  convert.
34       The history file is normally in the Condor spool directory; it is named
35       history. Since the history file is rotated, there may be multiple  his‐
36       tory files, and all of them should be converted. On Unix platform vari‐
37       ants, the easiest way to do this is:
38
39       cd `condor_config_val SPOOL`
40       condor_convert_history history*
41
42       condor_convert_historymakes a back up of each original history files in
43       case  of  a problem. The names of these back up files are listed; names
44       are formed by appending the suffix  .oldver to the original file  name.
45       Move these back up files to a directory other than the spool directory.
46       If kept in the spool directory, condor_historywill find the  back  ups,
47       and will appear to have duplicate jobs.

Exit Status

50       condor_convert_historywill  exit  with  a status value of 0 (zero) upon
51       success, and it will exit with the value 1 (one) upon failure.
