使用Orientdb中的etl进程创建顶点时发生OStorageException

Question

I am relatively new to OrientDB. I want to load a couple of CSV files to OrientDb. I loaded one of the file as a vertex and it worked fine, similarly, when I try to load another file the below exception is thrown

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

The first file (member-gm.csv) contained values as shown below

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,

The Json(Members.json) file which was created for loading the above file is

{
  "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"}
    ]
  }
 }
} 

I executed the json file with the command G:\\orientdb-community-importers-2.2.29\\bin> oetl.bat /AAB/Members.json Database AABdb and Vertex Member was created.

The 2nd vertex which I want to create is the payer vertex and the related csv(Payer_category.csv) is as below

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

The Related Payer.json file contains

{
  "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"}
       ]
    }
  }
}

When I execute the G:\\orientdb-community-importers-2.2.29\\bin> oetl.bat /AAB/Payer.json The below error is thrown

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

• All this is directly done on the server.
• I tried using the dbUsername and dbPassword properties as well, the result was the same

---------Edit----------------------------

When I try to create a new DB with second json file(Payer.json), a new db with the vertex Payer is created, its just that in an already existing db a new vertex is not getting created.

---

Any help will be much appreciated. Thanks

Answer 1

is it normal that the files have different name member-gm.csv member-en.csv ?? I try the case and it works fine, by the way, this error:

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 

it might be caused the server is up and running and you are doing the import with plocal or your server is down but you're connected by console....

hope it helps
