* sl_cache [#m18048f6] [[日本語はこちら>sl_cache]]~ ** Outline [#uf52edaf] -''sl_cache'' is a UDP Texture Cache Server for ''[[sl_relay>sl_relay (E)]]'' running on Linux. -By our measurements, the texture data accounts for about ''80%'' of all UDP data. -Cache data is saved in a plain file or Berkeley DB file. (It works fast enough even with a plain file) -''sl_cache'' doesn't rewrite the sequence number of UDP packets. It only saves data taking it out of the data stream. - ''sl_cache'' is part of ''[[sl_proxy>sl_proxy (E)]]''. - Current version is ''1.0.0'' (27 July '08) *** Outline of Functions [#gd1c99c9] +Texture data caching is enabled through ''[[sl_relay>sl_relay (E)]]''. ***Annoyances or Bugs. [#ie9ebcd0] +Cache data is saved in a plain file or a Berkeley DB file. SQL database is not supported. +The program has not been stress tested. ** Explanation [#y7c7c0f1] +[[Caching of Texture Data>./Caching]] +[[Texture Data Base>./Texture DB]] +[[When the server has two network interfaces or more>/sl_proxy (E)/two or more network interfaces]] +[[Log and Debug Mode>./Log and Debug Mode]] +[[Security>./Security]] ** Configuration [#c7736a3e] -The default configuration file is ''/usr/local/etc/sl_proxy/sl_cache.conf''. -It is also possible to specify other files if ''-f'' option of ''sl_cache'' is specified. -Because the configuration file is read before ''sl_cache'' does the switch to the effective user, exec user should be able to be read. -The setting of each item is described in the configuration file. Empty lines or lines starting with # are not read. *** Items [#w5d029f2] Ports for communication with Relay Server -[[MinUdpPutPort>./MinUdpPutPort]] -[[MaxUdpPutPort>./MaxUdpPutPort]] -[[MinUdpGetPort>./MinUdpGetPort]] -[[MaxUdpGetPort>./MaxUdpGetPort]] Number of transfer packets -[[GetPacketNum>./GetPacketNum]] Access Control -[[Hosts_Allow_File>/sl_proxy (E)/Hosts_Allow_File]] Etc. etc. -[[Temp_File_Dir>/sl_proxy (E)/Temp_File_Dir]] -[[MaxIdleTime>/sl_proxy (E)/MaxIdleTime]] ** Execute Options [#nb85999c] sl_cache [-p port_no] [-f config_file] [-u user_name] [-pid pid_file] [-i interface_address] [-v syslog_level] [-l [log_file]] [-fdb] [-d] -p : port number that Relay Server(sl_relay) connects. default is 8200. -f : configuration file. default is /usr/local/etc/sl_proxy/sl_cache.conf -u : effective user. -pid: pid file. -i : specify sl_relay side network interface IP address. If your server has two or more network interfaces you need to use this option. -v : level of syslog. default is LOG_INFO (7). -l : create log file. default log file is /var/sl_proxy/slcache.log -fdb: Berkeley DB is used for the data base. Default is plain file. -d : debug mode. **Processes [#b015ec30] *** Data Caching [#i946f8e2] -There is a two step data save process so that a single process can control the actually data save, thus avoiding file locking problems. http://www.nsl.tuis.ac.jp/xoops/modules/xpwiki/?plugin=ref&page=sl_cache&src=sl_cache.png - [Save Data Process] is ''Cache Put Server'' - [Get Cache Process] is ''Cache Control Process''
