Worklight 6.2 迁移工具错误 [英] Worklight 6.2 migration tool error

问题描述

我正在将数据从 WL 5.0.6.2 迁移到 6.2.在此过程中，我在运行数据迁移工具时遇到了问题.

I am working on migrating data from WL 5.0.6.2 to 6.2. While doing that I encountered problems running data migration tool.

背景:方法:我们将 WRKLGHT 表从 5062 DB 导出到中间 DB 进行数据迁移，所以运行的 DB 不受影响.

Background: Approach: we export the WRKLGHT table from 5062 DB to an intermediate DB for data migration so the running DB is not affected.

DBs:
   1. schema: proj
     its storing 5062 runtime data, upgrade-worklight-506-60-oracle.sql, upgrade-worklight-60-61-oracle.sql upgrade sql are executed.
   2. schema: proj6
     its blank DB at first, "create-worklightadmin-oracle.sql"  is executed to prepare WLADMIN tables.

WL Project existing:
    1. wlProj 
        its the app running on 5062 WL server
    2. wlProj6
        its the target project running on 6.2 WL, and data will be migrated to be used by this project

Steps:
1. recreate proj6 schema
    1.1 SQLPlus -> connect as SYSTEM -> "drop user proj6 cascade"
    1.2. -> "create user proj6 identified by {password}" -> "grant all privileges to proj6"

2. execute "create-worklightadmin-oracle.sql" on proj6 schema
     2.1 SQLDeveloper -> connect as user proj6
     2.2 run @"{ WL server install dir}/databases/create-worklightadmin-oracle.sql";
     2.3 commit

3. Open cmd and run the following command
    java -cp ojdbc6.jar;worklight-ant-deployer.jar com.ibm.worklight.config.dbmigration62.MigrationTool -p /wlProj   -sourceurl jdbc:oracle:thin:@//192.168.0.**:1521/xe   -sourcedriver oracle.jdbc.driver.OracleDriver   -sourceuser proj   -sourcepassword ***  -targeturl jdbc:oracle:thin:@//192.168.0.***:1521/xe   -targetdriver oracle.jdbc.driver.OracleDriver   -targetuser proj6   -targetpassword *** 2>out.txt

'迁移 wlProj-{ios,android}' &cmd中显示'migrating access data record for wlProj-.....'.

'migrating wlProj-{ios,android}' & 'migrating access data record for wlProj-.....' are shown in cmd.

而在out.txt中，显示如下错误.

And in out.txt, the following error is shown.
