  • 1.  Error 1422: could not open '%s' for writing

    Posted Sun June 28, 2020 05:36 AM
    I ran into out of memory errors, I read the forum and I changed the 'node file storage switch' to write the node file on disk compressed (option =3). Subsequently, i encountered this error 1422. I have fulll admin rights to write and have sufficient disk space.

    In the .ops file under Languang>Run, export format is currently 'No export' , is this the solution to the problem? which should i select/ how do i resolve the problem (how do i specify the directory for this node file?)? I run all my opl projects from the same folder.

    Hi,

    just to be sure can you change WorkDir

    https://www.ibm.com/support/knowledgecenter/en/SSSA5P_12.10.0/ilog.odms.cplex.help/CPLEX/Parameters/topics/WorkDir.html

    to a path where you know you for sure have all write access ?

    regards

    By default CPLEX will create the temporary files in the current working directory. More precisely, it will create temporary directories the name of which starts with 'cpx'. Do you see any such directories being created in your current working directory while CPLEX runs? (note that they wil be deleted once CPLEX terminates).
