Rolling back hotfixes by using a direct connection to the database

If an uncommitted hotfix introduces unwanted changes to your system, you can remove it by rolling it back using a direct connection to the database. This is most commonly done for a stopped instance.

CAUTION:
You cannot roll back committed hotfixes.
Note: Database schema changes associated with a hotfix are not removed when rolling back.

To roll back hotfixes by connecting directly to the database, do the following steps.

  1. Configure the common properties of the prpcUtils.properties file.

    Property name Value
    pega.jdbc.driver.jar Path to the database driver .jar file.
    pega.jdbc.driver.class The database driver class.
    pega.database.type Database vendor type.
    pega.jdbc.url URL of your database.
    pega.jdbc.username Database user name.
    pega.jdbc.password Database password.
    rules.schema.name If you use a split schema, the value for the rules schema name. If you do not use a split schema, the value for the schema name.
    data.schema.name If you use a split schema, the value for the data schema name.

  2. Configure the rollback properties of the prpcUtils.properties file.

    Property name Value
    hotfix.operation rollback
  3. Save and close the prpcUtils.properties file.

  4. Run the prpcUtils.bat or prpcUtils.sh script with the manageHotfixes option, for example: prpcUtils.bat manageHotfixes

    Optional: Pass one or more arguments.

    prpcUtils script argument Value
    connPropFile The full path to the connection.properties file that includes information for multiple targets.
    driverClass Your JDBC driver class. For example, oracle.jdbc.OracleDriver.
    driverJAR Location of your JDBC .jar file.
    dbType Database vendor type, such as mssql, udb, oracledate, postgres, and db2zos.
    dbURL JDBC URL to the database.
    dbUser Database user name.
    dbPassword Database password.
    archivePath Full path to the archive to be imported or exported.
    propFile The full path to the properties file, to override the default prpcUtils.properties.
    hfixAction If manageHotfixes is selected, sets the hotfix operation. Valid values are commit, rollback, generateDDL, install, and scan.
    rulesSchema The rules schema.
    dataSchema The data schema.
    noFailOnError Set to true or false. When enabled, instances that fail to import are skipped and import continues instead of failing.
    U Pega user name.
    P Pega password.
    accessGroup AccessGroup in which the Rule-Declare-Index of the classes being exposed exists. Applicable for the expose utility if --U or --P are not provided.
