我正在將數據從WL 5.0.6.2遷移到6.2。這樣做時我遇到了運行數據遷移工具的問題。Worklight 6.2遷移工具錯誤
背景： 方法： 我們將WRKLGHT表從5062 DB導出到中間數據庫進行數據遷移，因此運行的數據庫不受影響。
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
'遷移wlProj- {IOS，機器人}' & '遷移訪問數據記錄wlProj -.....' 示於CMD。
而在out.txt中，顯示以下錯誤。
