Email Alerts are not received...

In one of application, Email alerts are sent using SQL sp_send_dbmail stored procedure. Email alerts were working properly, but suddenly noticed email alerts are not received.

To troubleshoot the issue, first I checked the msdb.dbo.sysmail_event_log table using the below query.

SELECT log_id, event_type, log_date, description, process_id, mailitem_id, account_id, last_mod_date, last_mod_user
log_date DESC

If there is any error, you should see records with the event_type value as error.
In my case there are records with event_type value as error, and the description value for those records is same as below

The mail could not be sent to the recipients because of the mail server failure. (Sending Mail using Account 3 (2018-02-01T10:41:27). Exception Message: Cannot send mails to mail server. (The SMTP server requires a secure connection or the client was not authenticated. The server response was: Authentication required).  )

As per the error descript…

Connecting to Pervasive SQL using SSIS

I got an requirement from a client as connect to Pervasive SQL database system and retrieve data from it.

I was able to achieve that requirement using SSIS. For that we have to install the OLEDB driver for Pervasive SQL. After that create a SSIS package and add a OLEDB Source in the Data Flow Task. Then create a New OLEDB connection.
Select the Provider as Native OLEDB\Pervasive PSQL OLEDB Provider.
Then you have to provide the server or file name and the location. But there some confusion about those values. Because for this provider you have to provide the server which contains the Pervasive SQL database as the Location and the Pervasive SQL database as the Server or file name value. Then you have to provide the Initial Catalog value as well. Figure is shown below

Then click on All and under Pooling yow will see OLEDB Services. Select the value as Disable All as shown in the below figure.

Otherwise you will get and error as shown below figure while trying to preview data.

Then select that connection in the OLEDB Source and use SQL Command to retrieve data. Because I tried to get the list of tables and unable to do it due to memory exception.


  1. This post help me to fix the issues.
    Thanks a lot

  2. Were you not able to see the tables?

    I'm trying to connect SSRS to Pervasive, and it works but the user is not able to see the tables to construct a query visually, only the text command option works and the user does not know SQL.
