Rolling back hotfixes by submitting a request to an active instance

If an uncommitted hotfix introduces unwanted changes to your system, you can remove it by rolling it back. If you have an active instance of Pega Platform, you can roll back hotfixes by submitting a request to an active instance via a web service.

To invoke a web service to roll back hotfixes, do the following steps

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

   Property name	Value
   pega.rest.server.url	The URL for the REST service, specified in the following format: http:// <hostname> : <port> / <context> /PRRestService/ For example: http://myhost:8080/prweb/PRRestService
   pega.rest.username	The operator name on the target system with access to REST services.
   pega.rest.password	The password of the specified operator.
   pega.rest.proxy.host	The host name of the REST proxy server. Do not use localhost as the host name.
   pega.rest.proxy.port	The port for the REST proxy server.
   pega.rest.proxy.username	The operator name on the REST proxy server with import and export access.
   pega.rest.proxy.password	The password of the REST proxy operator.
   pega.rest.proxy.domain	The domain of the REST proxy server.
   pega.rest.proxy.workstation	The workstation ID for the REST proxy server.
   pega.rest.response.type	The REST response type, either xml or json. The default value is json. Rollback, restore point, and update access group operations support only json.
   user.temp.dir	Enter the full path to the temporary directory. Leave this blank to use the default temporary directory. For more information about temporary directories, see Temporary files.

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

   Property name	Value
   hotfix.operation	rollback
   hotfix.async	true or false. The default value, true, executes the hotfix operation asynchronously. The system queues the job and returns a JobID to use to get the job status. A value of false executes the operation synchronously.

3. Save and close the prpcServiceUtils.properties file.

4. Run the prpcServiceUtils.bat or prpcServiceUtils.sh script with the hotfix option, for example:

   prpcServiceUtils.bat hotfix

   Optional: Pass one or more arguments:

   prpcServiceUtils script argument	Value
   connPropFile	The full path to the serviceConnection.properties file that includes information for multiple targets.
   poolSize	The thread pool size. Default is 5.
   requestTimeOut	How long the system waits for a response before failing with a time-out error. Default is 300 seconds.
   jobIdFile	The path to the job IDs file that is generated by the asynchronous operation.
   propFile	The full path to the properties file, to override the default prpcServiceUtils.properties.

• Rolling back hotfixes

  If an uncommitted hotfix introduces unwanted changes to your system, you can remove it by rolling it back. You cannot roll back committed hotfixes. If you have more than one uncommitted hotfix, roll them all back and reinstall the hotfixes you want to keep.

• Committing hotfixes

  Commit all uncommitted hotfixes to make the hotfixes a permanent part of the system.
