Editor to share with you what are the common problems in using the zero code development platform. I hope you will gain something after reading this article. Let's discuss it together.

1. File upload size and speed

Uploading large files is related to many factors, such as server performance, network bandwidth, upload rate, memory size, timeout, and so on.

Test results:

1. 500mb files can be transmitted on the intranet within 5 minutes.

2. More than 900 mb files can be transmitted on the intranet in 11 minutes.

Second, the integrated desktop version of the service starts an error

Solution: set IE or Google as the default browser.

III. The basic connection has been closed: the connection was closed unexpectedly

Problem description: when deploying the component, an error was reported that "the basic connection has been closed: the connection was closed unexpectedly." .

Reply: there are several reasons, please try to solve:

1. Determine whether the database connection is successful.

2. See if the server memory is full.

4. packing exception. Please check whether the execution file exists.

If an error is reported during the packaging process, "packing exception, please check if the execution file exists: d:\ v3\ DevSystm\ VDevenv.exe"

Reason: framework4.0 is not installed on this machine

5. SQL check the lock table

Select request_session_id as spid

, OBJECT_NAME (resource_associated_entity_id) as tableName

From sys.dm_tran_locks

Where resource_type='OBJECT'

Query the preview above sql in the database, and if there is a result, it proves that the table is being occupied by the transaction and that the transaction has not been completed.

Deal with:

1. If you are not sure what the transaction is doing or who submitted it, please do not touch it.

2. If you are sure that the transaction was committed by yourself and know the operation of the transaction, you can execute KILL spid to end the transaction and release the table lock.
