Create a folder called install under the crx-quickstart folder of your AEM installation
Create a file called org.apache.aries.transaction.config with the following content
aries.transaction.timeout=“1200”
under install folder. You can change the timeout value as per your requirement. The timeout value is in seconds
NOTE
Once you create the org.apache.aries.transaction configuration you can edit the transaction timeout values from the configMgr instead of editing the file
Add the following entry
jacorb.connection.client.pending_reply_timeout=600000
The above setting sets the pending reply timeout (also known as, CORBA client timeout) to 600 seconds.
