Release : DevTest 10.7.2

Component : DevTest Install/Upgrade


Sometimes IAM DB is corrupted or because of user details in database, details are not imported/exported correctly and causes this issue during upgrade.


Follow the below steps to take backup of IAM default database h2 before starting the upgrade:
  1.  Run below command to copy keycloak h2 database in your local machine:
  2. kubectl cp <iaam-pod>:/iam/standalone/data/keycloak.mv.db .
  3. Run below command to copy h2 jar in your local machine:
    kubectl cp iaam-pod:/iam/modules/system/layers/base/com/h2database/h2/main/h2-1.4.193.jar . 
  4. Check if Java 8 is there in your local machine:
    java -version
  5. Take backup of the h2 database in your local machine:
    java -cp h2*.jar org.h2.tools.Script -url jdbc:h2:./keycloak -user sa -password sa
    This will create backup.sql in your local machine.

Now upgrade the environment to latest version. After completion of upgrade, follow the steps to restore the backup data.

1. Go to {LISA_HOME}/IdentityAccessManager/standalone folder and create data folder.
2. Go to data folder and copy the backup.sql file.
3. Run the below command to restore backup:
java -cp ../../modules/system/layers/base/com/h2database/h2/main/h2*.jar org.h2.tools.RunScript -url jdbc:h2:./keycloak -user sa -password sa
4. Go to {LISA_HOME}/IdentityAccessManager/bin directory and Start ./IdentityAccessManager.sh
5. Check if all the data comes
