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.

You cannot roll back committed hotfixes.

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 (example: oracle.jdbc.OracleDriver).
   driverJAR	Location of your JDBC .jar file.
   dbType	Database vendor type (mssql, udb, oracledate, postgres, 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.
