SIM DB anchor.png

  • The Plane file and Berkeley DB can be used as a Tecture DB in v1.0.0.
  • When sl_info is started with -fdb option, Berkelry DB is used. Default is Plane file.
  • The speed goes out enough also even if it is Plane file of default.
  • It is necessary to specify --enable-db option with configure of sl_proxy and TUIS_Lib to use Berkeley DB.

The data of SIM preserved in DB is

  • SIM Name. (32Byte)
  • GUID of SIM. (40Byte)
  • Region Handler. (8Byte)
  • SIM's IP address. (Binary form. 4 Byte)
  • SIM's access. (2Byte)
  • State of data. (2Byte)
  • X coordinate of SIM. (4 Byte)
  • Y coordinate of SIM. (4 Byte)
  • Update Time. (Linux Time. 4Byte)

  • In SIM DB, to make SIM name and the region handler a retrieval key, two kinds of data bases are made. Contents are the same. As for these DB, the file name (key) is only different.

When the region handler is a key (file name) anchor.png

  • The directory named 'info/sim_handle ' is made for work directory Temp_File_Dir, and the subdirectory named 000, 001, 002, ......., 254, and 255 is made in the directory.
  • These subdirectories are assumed to be a modulo to 256 of the X coordinates of SIM, so SIM data is classified, and it preserves it.
  • The file name becomes X coordinate(6digits)-Y coordinate(6digits) of SIM.

Ex.) /var/sl_proxy/info/sim_handle/243/001011​-000987

When the SIM name is a key (file name) anchor.png

  • The directory named 'info/sim_name ' is made for work directory Temp_File_Dir, and the subdirectory named @, A, B, ......., Y, and Z is made in the directory.
  • These subdirectories are assumed to be an initial of SIM name, SIM data is classified, and it preserves it. @ is used to classify SIM of the initial other than the alphabet.
  • The file name when preserving it becomes SIM name.

Ex.) /var/sl_proxy/info/sim_name/T/TUIS

Berkeley DB anchor.png

  • The directory named 'info ' is made for work directory Temp_File_Dir.
  • Two DB files are made by SIM name and region handler as keys.

Ex.) /var/sl_proxy/info/sim_info.db, /var/sl_proxy/info/sim_info_handle.db
