Metering and Throttling for Document Generation

Retrieve Blocked Server-Side Document Generation Requests Using Apex Class

Retrieve blocked server-side document generation requests for specific timeframes. Blocked requests are reprocessed via new server-side document generation requests.

Sample Code to Retrieve Blocked Requests

Modify the sample code to create an Apex class for retrieving blocked server-side document generation requests.

Global class DocGenRetryBlockedBatch implements Database.Batchable<sObject> {
	private DateTime startTime;
	private DateTime endTime;
	public DocGenRetryBlockedBatch(DateTime startTime, DateTime endTime) {
    	this.startTime = startTime;
 	   this.endTime = endTime;
	}
   
	global Database.QueryLocator start(Database.BatchableContext BC) {
    	DateTime dt = System.Now().addHours(-1);
    	String query = 'SELECT Id, Type ,RequestText, TokenDataContentDocumentId , TokenData from DocumentGenerationProcess where Status =\'Blocked\' and LastModifiedDate >=:startTime and LastModifiedDate <=:endTime';
    	return Database.getQueryLocator(query);
	}


	global void execute(Database.BatchableContext BC, List<DocumentGenerationProcess> blockedList) {
    	List<DocumentGenerationProcess> ls = new List<DocumentGenerationProcess>();
    	for(DocumentGenerationProcess blockedObject:blockedList)
    	{
        	DocumentGenerationProcess myCustomObject = new DocumentGenerationProcess (
            	Type = blockedObject.Type, Status = 'InProgress',
            	RequestText= blockedObject.RequestText,
            	TokenDataContentDocumentId= blockedObject.TokenDataContentDocumentId,
            	TokenData = blockedObject.TokenData
        	);
        	ls.add(myCustomObject);  
    	}
    	insert ls;
	}
   
	global void finish(Database.BatchableContext BC) {
    	// execute any post-processing operations
     }
}

3. In the Enter Apex Code dialog, enter this sample statement:

   DocGenRetryBlockedBatch dgrb = new DocGenRetryBlockedBatch(
   DateTime.newInstance(2022,10,17), DateTime.now());
   Database.executeBatch(dgrb);
   

4. Select the statement you pasted.
