随机无法从 Windchill PDMLink 下载大文件
已修改: 29-Mar-2024
适用于
- Windchill PDMLink 11.1 to 12.1
- PTC Cloud Installations deployed using the Amazon CLB (deployed Spring/Summer 2023 or earlier)
说明
- 无法下载较大的文件（通常大于 350MB）
- 无法下载大于 600MB 的文件
- 大文件内容下载随机失败
- 在内容下载期间，Amazon Classic Load Balancer (CLB) 可能会重置与 Windchill 服务器的网络连接
- Apache 访问日志仅显示正在下载的大文件的一部分（通常约为 350-600MB）以及再次请求该文件但失败并返回 500 响应：
<IP date time> "GET /Windchill/servlet/WindchillGW/wt.fv.master.StandardMasterService/doDirectDownload/<filename>?folderId=####&ft=FF&userid=####&adId=####&fileName=####&refsize= <large file size in bytes> &mime=application/zip&mk=wt.fv.master.StandardMasterService&ofn=<filename>&c=8&riid=-1&sT=####& sign=#### %3D&site=https%3A%2F%2F<site>%2FWindchill%2Fservlet%2FWindchillGW&AUTH_CODE=HmacSHA256&isProxy=true HTTP/1.1" 200 <smaller file size around 350-600MB> 3239687 <IP date time> "GET /Windchill/servlet/WindchillGW/wt.fv.master.StandardMasterService/doDirectDownload/<filename>?folderId=####&ft=FF&userid=####&adId=####&fileName=####&refsize=<large file size in bytes>&mime=application/zip&mk=wt.fv.master.StandardMasterService&ofn=<filename>&c=8&riid=-1&sT=####&sign= <same signature #### > %3D&site=https%3A%2F%2F<site>%2FWindchill%2Fservlet%2FWindchillGW&AUTH_CODE=HmacSHA256&isProxy=true HTTP/1.1" 500 999 5384
- Methodserver日志报告下载错误：
