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.
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
'migrating wlProj-{ios,android}' & 'migrating access data record for wlProj-.....' are shown in cmd.
And in out.txt
, the following error is shown.
