Introduction

This page describes how to flush old requests (put, get, copy and bring online requests) of the DPM DB. Tables affected are dpm_put_filereq, dpm_get_filereq, dpm_req and dpm_copy_filereq. For the moment, the tool works only for MySQL DB. if you need it for Oracle, please send me a mail. This tool must be used as long as the flushing mechanism is not integrated in the DPM server.

Outline of the tool

The tool consists of a command line dpm-flush-req which takes the following input arguments:
  • dpm_db_name : the DPM DB name (yaim uses by default dpm_db). However there is no default value
  • dpm_db_host : the DPM MySQL DB host name (need to be put even if you run the command locally, i.e. if localhost is passed as dpm_db_host, the db connection will fail
  • dpm_db_pwd : password of the DPM DB
  • dpm_db_user : login od the DPM DB(yaim by default uses dpmmgr)
  • max_request_lifetime : maximum time to keep a request in the tables. Time to be given in seconds. If this argument is omitted, the default value is 2592000

Installation

Download and extract the tar file. Type make and if needed edit the makefile to match your environment.

Example of usage

To delete old requests which have been performed two months (5270400 sec) before, type:
./dpm-flush-oldreq --dpm_db_name dpm_db --dpm_db_pwd  --dpm_db_host lxn1177.cernc.h --dpm_db_user dpm_mgr --max_request_lifetime 5270400

Any problems or questions?
