我正在将数据从WL 5.0.6.2迁移到6.2。在这样做时，我遇到了运行数据迁移工具的问题。
背景:方法:为了进行数据迁移，我们将wrklight表从5062 DB导出到一个中间DB，这样运行中的DB就不会受到影响。
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
' migration wlProj-{ios,android}' &'为wlProj-.....迁移访问数据记录
在out.txt中，显示如下错误:
