Hello,I have implemented a way to make Alfresco read-only during the time that we back it up, by using a Toggle (http://cedric.bosdonnat.free.fr/wordpress/?p=87). We have a single server, so i dont have the option of having a slave for backing up.I can successfully make Alfresco read-only using the above toggling method by scheduling a java app to run, which runs the following code: TransactionService myTransactionService = this.services.getTransactionService();
TransactionServiceImpl serviceAction = (TransactionServiceImpl)myTransactionService;
boolean status = myTransactionService.isReadOnly();
if(aToggle && !status)
{
//toggle read only
serviceAction.setAllowWrite(false);
aMessage = "Alfresco in read-only status";
System.out.println("Toggling read-only");
}
This all works well, however I am using Alfresco as a backend to a Joomla website. Joomla will access various webscripts in Alfresco when a user browses the pages, so the Alfresco webscripts have to be up 24/7. When i have the toggle to read-only, I can run webscripts if they dont contain a .js, however as soon as i run webscript with a .js, i get the following error: <status>
500
<name>Internal Error</name>

My web script has the following authentication: <authentication>guest</authentication>
<transaction>none</transaction>
The Web scripts are not writing to Alfresco or the database - they are actually read-only. Is there a way to overwrite the safety check which causes the error above? Thanks in advance for your help!Tara
