ARCMAIN is the program name of the Teradata ARC utility. ARCMAIN uses these files:

  • Input – (required) contains archive and recovery control statements that have been created.
  • Output log – contains all runtime messages that are output from the utility. The file indicates, statement by statement, the activity that occurs from the statements in the input file. This file is generated automatically.
  • Restart log – contains restart recovery information for internal use. The utility places into this non-readable file the information that it needs if a task is terminated prematurely and then restarted (with the RESTART runtime parameter). This file is automatically generated.
  • Stack Trace Dump file – contains stack trace information for internal use. This file is generated automatically for certain error conditions.
  • Archive – contains archival data. An output archive file is the target of the data provided by an ARCHIVE statement. An input archive file is the source of data for restoring a database or table. Any number of archive files can be used during a utility run. Use the FILE parameter of the RESTORE/COPY or ARCHIVE statement to identify the names of input and output archive files. This file is required only if the task involves the creation of an archive or the restoration of a database or table.

Although Teradata ARC is able to process up to 350 ARCMAIN jobs at a time, each with up to 1024 sessions, avoid running so many jobs.
