我对 OrientDB 比较陌生。我想将几个 CSV 文件加载到 OrientDb。我将其中一个文件加载为顶点，它工作正常，同样，当我尝试加载另一个文件时，抛出以下异常

com.orientechnologies.orient.core.exception.OStorageException：无法使用 mode=rw 打开本地存储“../databases/AABbd”

原因：com.orienttechnologies.orient.core.exception.OStorageException：无法打开存储它被其他进程获取

第一个文件 (member-gm.csv) 包含如下所示的值

MEMBERID,ENROLLBEGINDATE,ENROLLENDDATE,Dental,Drug,MHInpt,MHDN,MHAMB,CDInpt,CDDN,CDAMB,Hospice,Payer,PEFlag,Ind
95000,20141118,20160328,Y,Y,Y,Y,Y,Y,Y,Y,N,MCS,N,A
95001,20150225,20181231,Y,N,Y,Y,Y,Y,Y,Y,N,POS,N,A
95002,20150607,20160620,Y,Y,Y,Y,Y,Y,Y,Y,N,MLI,N,

为加载上述文件而创建的 Json(Members.json) 文件是

{
  "source": { "file": { "path": "/G:/AAB/member-gm.csv" } },  
  "extractor": { "csv": { "columns":    ["MEMBERID","Gender","DOB","LName","FName","MMidName","SubID","Add1","Add2","City","State","MZip","MPhone","PFirstName","PMidName","PLastName","Race","Ethn","RaceDS","EthnDS","SpokenLang","SpokenLangSource","WrittenLang","WrittenLangSource","OtherLang","OtherSource"],
       "columnsOnFirstLine": true } },
"transformers": [
{ "vertex": { "class": "Member" } }
],
"loader": {
"orientdb": {
   "dbURL": "plocal:../databases/AABbd",
   "dbType": "graph",
   "classes": [
     {"name": "Member", "extends": "V"}
    ]
  }
 }
}

我使用命令 G:\orientdb-community-importers-2.2.29\bin> oetl.bat /AAB/Members.json 执行了 json 文件， 并创建了数据库 AABdb 和顶点成员。

我要创建的第二个顶点是付款人顶点，相关的 csv(Payer_category.csv) 如下

ID,Payer_Line,Payer_Name,Input_Payer,Output_payer
1,Medicaid,Medicaid,MMP,MCD
2,Medicare,Medicaid Dual Eligible HMO,MDE,MCR
3,Medicaid,Medicaid Dual Eligible HMO,MDE,MCD

相关 Payer.json 文件包含

{
  "source": { "file": { "path": "/G:/AAB/Payer_category.csv" } },  
  "extractor": { "csv": { "columns": ["ID","Payer_Line","Payer_Name","Input_Payer","Output_payer"],
                            "columnsOnFirstLine": true } },
  "transformers": [
    { "vertex": { "class": "Payer" } }
  ],
  "loader": {
    "orientdb": {
       "dbURL": "plocal:../databases/AABbd",
       "dbType": "graph",
       "classes": [
         {"name": "Payer", "extends": "V"}
       ]
    }
  }
}

当我执行 G:\orientdb-community-importers-2.2.29\bin> oetl.bat /AAB/Payer.json 抛出以下错误

G:\orientdb-community-importers-2.2.29\bin>oetl.bat /AAB/Payer.json

  • 所有这些都直接在服务器上完成。
  • 我也尝试使用 dbUsername 和 dbPassword 属性，结果是一样的

- - - - -编辑 - - - - - - - - - - - - - -

当我尝试使用第二个 json 文件（Payer.json）创建一个新数据库时，会创建一个带有顶点 Payer 的新数据库，这只是在一个已经存在的数据库中没有创建一个新顶点。

任何帮助都感激不尽。谢谢

文件具有不同的名称 member-gm.csv member-en.csv 是否正常？我尝试了这个案例，它工作正常，顺便说一下，这个错误：

com.orientechnologies.orient.core.exception.OStorageException: Cannot open local storage '../databases/AABbd' with mode=rw

Caused by: com.orientechnologies.orient.core.exception.OStorageException: Cannot open storage it is acquired by other process

这可能是由于服务器已启动并正在运行，而您正在使用 plocal 进行导入，或者您的服务器已关闭但您已通过控制台连接....

希望能帮助到你
