SQL Server Transaction per interval

If you are wondering how much SQL transaction is happening on your database, run the below query.

DECLARE @First INT
DECLARE @Second INT
SELECT @First = cntr_value
FROM sys.dm_os_performance_counters
WHERE OBJECT_NAME = 'SQLServer:Databases' -- Change name of your server
AND counter_name = '%Transactions/sec%'
AND instance_name = '_Total'; -- Database name
-- delay time
WAITFOR DELAY '00:00:01'
SELECT @Second = cntr_value
FROM sys.dm_os_performance_counters
WHERE OBJECT_NAME = 'SQLServer:Databases' -- Change name of your server
AND counter_name = '%Transactions/sec%'
AND instance_name = '_Total'; -- Database name
SELECT (@Second - @First) 'TotalTransactions'
GO

If you are having some problem in execution, please confirm the OBJECT_NAME and instance_name by running select * FROM sys.dm_os_performance_counters. You can change the WAITFOR DELAY time to meet your time interval requirement. I have used currently 1 Second.

Zimbra Mail Error: not enough free space in mail queue

If you are using Zimbra Mail and you are not able to send any mails and also you see an Error Message " not enough free space in mail queue " under /var/log/message. Then you should try out this solution. 1. Login to the server, and then again login as zimbra as follows: #su - zimbra 2. Check the Postfix message_size_limit, by default it should be 10MB (i.e. '10240000' bytes) as follows: $postconf message_size_limit message_size_limit = 10240000 3. If the value is higher than that, set it as follows to 10MB $ zmprov modifyConfig zimbraMtaMaxMessageSize 10240000 $ postfix reload Now try sending Mail, It should work. You could try out this solution for Error: " SMTP Server Reported: 452 4.3.1 Insufficient System Storage "
