Set maximum file size or maximum number of points for a dynamic archive

To set a limit on the file size (maxsize) or the number of points (maxpoints) of a dynamic archive, use piarcreate or piartool. (You cannot perform this operation using PI SMT.)

• Use piartool to create and register a dynamic archive file and set the maxpoints and maxsize values using the following syntax:

  piartool –acd path maxpoints maxsize

• Use piarcreate to create a new archive file and set the maxpoints and maxsize values using the following syntax:

  piarcreate –d path maxpoints maxsize

• For example:

  C:\PI\adm>piarcreate -d D:\PI\dat\piarch.115 2000 20000
  Attempting to create a 2000 record, dynamic archive: D:\PI\dat\piarch.115 with a maximum size of 20000 Mbytes.
  Initializing archive file: D:\PI\dat\piarch.115
  Archive D:\PI\dat\piarch.115 is prepared to be registered

• Use piarcreate to change the maxpoints parameter:

  G:\pi\adm>piarcreate -?
  Usage: piarcreate -v
  
  piarcreate -d path maxpoints maxsize(Mb)
  piarcreate path size(Mb)

• The following listing is for a 2048 MB archive; the maximum number of configurable points for the archive is 1,048,576 (half the total number of records).

  D:\PI\adm>piartool -al
