Rollback plan for SP1 on Sql Server 2014

Dear all,

I'm gonna to update this SP on UAT however if some issues are identified I can revert the new improvements for Cardinality Estimator reverting to 110 level with ALTER DATABASE.... but I was wondering how to rollback nowadays one SP in the latest versions of SQL. I mean, in the past I read that you need to back up non user databases (model, master) ?

To tell the truth my current idea is simple and perhaps naive: just add/remove applet in Control Panel. ?¿?

Any links related to would be greatly appreciated.

HI All,

We are planning to move few databases from one server to other server by backup and restore method.  

1) To ensure no write operation during migration activity Please let us know the options we can have.

2) if we can set the databases in read only mode and take a backup and restore on new server do we need to ensure anything else?

Regards,

Varu

Server Audit / DB specification action types

Hi,

I have been tasked with creating a server level audit speciation as well as individual DB level audit specifications and asked to add all available audit action types.

I was just wondering if anyone has any SQL handy for adding all available actions for a given DB / Server audit specification? This is for SQL 2012 Enterprise Edition.

Otherwise it seems to be a manual task of selecting every option from the dropdown!

Thanks in advance for any help.

Regards,

Phil

Set up of data and log file

Hi guys, I had to set up a huge database and I don't know if the set up is correct.

Simple recover (there are no transaction, just, let's say, a sort of DW).

File Type Rows Data

Initial Size 1000000 Limited to 1400000

Autogrowth in Megabytes 10000

Log

Initial Size 10753

AutoGrowth by 256 Limited to 2097152

This database takes data from another huge database using insert into from, etc; so produce tons of log file (bad coding but I can't do nothing about). Should I review the log set up in order to give them more performance?

Thanks

Hi there,

When you kill one SPID you get another one. You see that in the same window by using 'select @@spid'. Butlogin_time starts taking the last last_batch for the killed spid.

is it possible to change that?

Thanks in advance

Thank you.

backup/restore all dbs

Hi experts,

I need to migrate sql to a new server... Right now it’s running on windows 2008 r2, they are going to delete the vm and give me a new one with windows 2012.  

The sql instance is 

Microsoft SQL Server 2008 R2 (SP1) - 10.50.2500.0 (X64)   Jun 17 2011 00:54:03   Copyright (c) Microsoft Corporation  Enterprise Edition (64-bit) on Windows NT 6.1 <X64> (Build 7601: Service Pack 1) (VM) 

(I know it’s outdated but app team wants to use this same version/SP). 

I plan on backing up all databases and users to a safe folder and then restoring them, but I have a few questions. 

 

-do I need to script out sql agent jobs? Or they get backed up when I back up msdb?

-When restoring should I first restore system databases or user databases?

 

Any lesson learnt/ helpful link would also be useful, thanks!

Database access problem (2014)

May 25, 2016, 7:22 am
$

Hi,

I have a user security problem; an application user cannot run a view which references to another database. Say we have 'DB1' and within it 'app_view'. app_view uses some tables form DB1 and one from DB2. The following error message is displayed.

Msg 916, Level 14, State 1, Line 3
The server principal "app_user" is not able to access the database "DB2" under the current security context.

I checked the following for 'app_user'.
It exists in DB2.
It has DATABASE CONNECT permission.
It has OBJECT_OR_COLUMN SELECT permission.
The user is valid, the sid of the user is the same as the login's.

I ran the view again, I received the same error message.

Then I set the TRUSTWORTHY property to True in DB1.
Then suddenly the Replication Log Reader Agent stopped. (DB1 has transactional replication)
Therefore I changed the option back to False.

I am really puzzled, so I would appreciate any idea how to resolve this.
We have Microsoft SQL Server 2014 (SP1-CU4) Enterprise.

Many thanks.

Hi guys,

I am struggling with one particular db, let's say L1. The developer is moving data from one db to L1. I am talking about millions rows, so I had to set up a lot of space for the database. This is the configuration:

Rows..Initial Size 1000000 Autogrowth By 10000 MB Limited to 1400000 MB

Log Not Applicable Initial size 10753 Autogrowth By 256 MB Limited to   2097152

Simple recover (it is not a production database, so no really care about the log).

Any advice?

Thanks

RESTORE VERIFYONLY

May 26, 2016, 12:58 pm

Hi experts,

I am doing a migration… basically they are deleting my vm (sql server) and switching from vmware to hyperv

A few questions

1-   The fact of now having hyper should not affect the sql server right?

2-   I will backup all databases the day before, as we are backuping to an external drive and takes some hours… will a RESTORE VERIFYONLY FROM DISK take the same time as the backup itself? I am planning on not doing the verifyonly, is it really necessary?

3-   Is there any best practice: should I put the dbs to read only before doing that, so the users later will not complain about a lost update/insert they did…

 

Thanks!!

Hello,

I successfully connect Amazon RDS to MS SQL Server Express (2014) and to Visual Studio projects on my Work PC, but  at my home PC I can't connect to this instance.  MS SQL Server Management Studio persist me showing this message error:

Cannot connect to debitor... ...eu-central-1.rds.amazonaws.com,1433.

===================================

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - The wait operation timed out.) (.Net SqlClient Data Provider)

Error Number: 258
Severity: 20
State: 0

...

===================================

The wait operation timed out

On my work PCs is installed Windows 7 and I never got any error message like this one above. At home PC I use Windows 10 ( and MS SQL Server Express 2014) and it have never been succesful to connect to Amazon RDS instance.

I have tried to extend connection time-out, disabling windows firewall, but no success.

What might be preventing me from having a succesful to this instance?

Any suggestions would be very appreciated, Thanks.
