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
-
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:
For example:http://
<hostname>:
<port>/
<context>/PRRestService/
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

pega.rest.proxy.username

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 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 offalse
executes the operation synchronously. - Save and close the
prpcServiceUtils.properties
file. -
Run the
prpcServiceUtils.bat
orprpcServiceUtils.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

- 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.
