cognos通过url拼接用户名密码方式访问报表或多维分析不稳定？

固定报表url如下所示： 服务器地址+p2pd/servlet/dispatch?b_action=cognosViewer&ui.action=run&ui.object=%2fcontent%2ffolder%5b%40name%3d%27publish%27%5d%2freport%5b%40name%3d%27+ 表名 +%27%5d&ui.name=表名&run.outputFormat=&run.prompt=false&cv.toolbar=false&cv.header=false&参数&CAMUsername=登录名&CAMPassword=密码 多维分析url如下： 服务器地址+p2pd/servlet/dispatch?b_action=xts.run&m=portal/main.xts&m_redirect=%2fp2pd%2fservlet%2fdispatch%3fb_action%3dxts.run%26m%3dportal%2flaunch.xts%26ui.gateway%3d%252fp2pd%252fservlet%252fdispatch%26ui.tool%3dAnalysisStudio%26ui.action%3dedit%26launch.openJSStudioInFrame%3dtrue%26ui.object%3d%252fcontent%252ffolder%255b%2540name%253d%2527publish%2527%255d%252fanalysis%255b%2540name%253d%2527%25e6%258f%2590%25e7%258e%25b0%25e6%2595%25b0%25e6%258d%25ae%25e6%2597%25a5%25e5%25a4%259a%25e7%25bb%25b4%25e5%2588%2586%25e6%259e%2590%25e8%25a1%25a8%2527%255d%26ui.drillThroughTargetParameterValues%3d&CAMUsername=登录名&CAMPassword=密码 多维分析偶尔出现提示登陆界面，有时候是正常显示，请问是什么原因？

有没有可能是没有指定namespace?连接不同的环境，两种以上namespace就需要手动登录了
