Hello,

I've a problem during the execution of one graph:

"Graph definition file: FREF002_Maj_OD_Date.grf

Does anybody has an idea about the origin of this error ?

Thanks,

  Thanks, apparently it was the first solution.
  I put all the components of my graph in the same phase and the execution was ok.
  
  I don't understand the system of phase. Is it explain somewhere ? I don't know when I can pass to another phase and when I can't ?
  
  Thanks again David.

  Just one word to say that in fact, the problem was about the tmp directory.
  His properties were not ok.
  So it was not a problem with phases.
  
  thanks again David

  Hi !
  
  There is "The Concept" document on clover's web - http://cloveretl.berlios.de/docs/doc1.html which explains basis about graph, nodes, edges, phases.

  Hi !
  
  It looks like the problem occures when intializing Edge. That can be cause by two reasons:
  a) the edge is Phase-crossing edge and Clover needs to allocate temp-file - at that point it fails
  b) you are using Edge in debug mode which means whatever flows through that Edge is duplicated to a file which has to be created
  c) some other obscure reason :-)
  
  In either case, check where Java's "java.io.tmpdir" property points (also check your TEMP/tmp environment variable).
  
  Also, you could send me the graph file for more detailed analysis (to david.pavlis@centrum.cz).
  
  David.
