DR Planning Help....
Mar 8, 2007
I was told that my company is thinking about inplementing a "backup" server for out content loading server (aka load server)... this server loads files from several companies and then replicates the data out to our production environment to be seen. This server has serveral DTS/IS packages that do all this data movement and manipulation... I am not too up to date on technology for what they are asking so I thought I would ask here for some recommendations to head in the right direction...
I am not sure if clustering will work or maybe mirroring the database...
The server now is a publisher so the backup server would have to pick up if the #1 failed and then give command back to #1 once it is good... this is the part I have no idea about...
The #2 server would not have to really do anything but keep its data up to date unless #1 fails so you could say it would be fine to be a passive server...
Any ideas on what direction I should look into???
Thanks ahead of time.

Hi Guys,
We are planning for a new SQLSERVER for one of our application. The database will receive around 58 million events/year is roughly 160,000 messages/day
Making the assumption that an average message size is 2K. The messages comes to database through edi processes.
Any suggestion about database server configuration, and any other steps that need to be take care of before even thinking about creating a database??
help is greatly appericated..

Hi all,
I'm very new to SQL and am learning via books and whilst on the job. I'm putting together my logical design at the moment and was wondering if anyone could suggest any websites that might give me an insight into the best way to go about this in an effective manner.
TIA,

HelloBased on three tables (Projects, Tasks and UserCalender) I would liketo work out the total amount of available resources (UserCalendertable contains a entry for each user for each day, day being 7.5hours) and total required effort (sum of Tasks.EstimateLikley) splitover 12 months.For example:Jan:Available Resources: (4 Users, 7.5 hours per day, 5 working days perweek, 23 Working days in Jan) = (23 x 4) = (92 * 7.5) = 690 AvailableHoursRequired Resources:Project Start Date: 1/1/2007Project End Date: 1/6/2007Total Required effort (Sum of Tasks.Hours for above project): 500Hours Average over 6 months = 83.33 Hours per month, so in Jan I needto deduct 83.33 from 600 = 516.67 Hours.etcHow could I do this, I have tried several ways but finding it hard.Thanks

I've read a few posts on the stored procedure vs dynamic sql debate. I ran a few performance test for myself and it appears to be a wash.
Given that, I'm leaning toward dynamic sql mostly because it would mean one fewer place to have things.
But, before we go that route we wanted to ask the question:
Is there any compelling reason why we shouldn't abandon all of our stored procs and just write the SQL inside inside our functions in our business layer (essentially our data access layer)?
Or, is it just preference these days?
I was leaning toward procs, but I have to admit it would be nice not to have to keep up with all of them per all of our functions that call them.
Thanks,
Ron

hallo
we have a sql2000 in the headquarter, and 3 new remote branches opening in few weeks with no sql servers installed yet.
We plan to setup a merge replica. The headquarter will have the highest activity on the replicated tables.
Shall we use all SQL2000 in the remote branches? Or could we use SQL2005, using a 2005 as a publisher and distributor?
TIA

With the current web app that I am writing, I am starting to plan ahead to the scalability problems that I am planning on encountering with the number of users that I may have...
My hosting plan now allows for a 50MB SQL Server database, but, I know that will not last long, each user will be using 3-5MB each of the database, so I am going to outgrow my space fast.
Would looking into (until i have enough subscribers to get a dedicated host), SQL Hosting be a good idea? Atleast to start off with something like http://www.alentus.com/hosting/sqlserver.asp ?
But then again, would a SQL Database growing to large get bad? Within a few years, i expect to have at max 5,000 users, so that could grow to a 25GB database... with millions of rows.
Would breaking it up into smaller databases for each N amount of users be a wise idea? Or would it not really matter?
Any help is much appreciated
Happy New Year
Harold.

Dear Experts,
now i was allotted as a complete DBA for one client and i've to take care from the creation itself.
we've understood the data will be around 20 GB initially, and from there onwards, 1GB data will grow in the database. total number of tables are around 1400. and we have primary key on each table.
Now you Experts, please guide me that how can i take the Fragmentation levels for best performance? or i need to give you more information regarding that.....
i need your valuble suggesions and guidence

I'm cleaning data which involves updating ~12 million rows with threedifferent models, progressively. First clean values using the modelwith finest granularity, then the remainder with the next model,finally what's left using the last model. The first model sets ~1/2 ofthe rows, the second ~1/4, the third ~1/5, and the remaining 5% don'tget updated.It's something like this:UPDATE t SET value=value*m.AdjustmentFactor, updateFlag='updated'FROM Table t JOIN Models m ON ....WHERE m.ModelID='first model' AND t.updateFlag IS NULLStart with 'first model' then 'second model' etc.I'm wondering what happens if I submit all three queries together, oras three separate submissions, waiting for the one before to complete.If I do them all as one group, the query planner might plan for thesecond and third updates based on the initial distribution of values.However, the first update removes half of the rows from consideration,so it seems to me a new plan should be prepared for the second query,based on the distribution at that time. If I highlight the queries inQuery Analyzer and execute, are all three plans created at thebeginning? Does putting GO between them (which I do) make anydifference?This is SQL Server 2000.Thanks,Jim

I've done a fair amount of hardware planning for the SQL Server Database Engine. Now I'm doing so for SSRS which I don't have as much experience with. I haven't been able to find much information, especially around RAM capacity and have a few questions. Any responses or pointers to resources are appreciated.
Scenario: 2 load-balanced SSRS 2005 App servers with an independent back-end SQL DB for the config database. Total userbase is about 2000 (not simultaneous), and I'm still trying to get statistics for per hour requests. May also install multiple SSRS instances on these boxes with one of them in Sharepoint Integrated mode (don't anticipate high volume here). Load-balancing is for both performance and availability goals.
I'm looking at the SSRS App servers only and am analyzing amount of RAM, 32 vs 64 bit, and perhaps CPU core count.
1. Does 32-bit Enterprise SSRS benefit from more than 4 GB on a server, using AWE or other memory extension? Or is anything > 4 GB unused at 32 bit?
2. Are there material benefits to going to 64-bit OS / SSRS and increasing memory above 4 GB? (does IIS handle this?), Perhaps to 8 or 16 GB.
3. The boxes will be 2-way, dual core, with possibility of going to quad core. Is increasing core count a better use of budget than increasing RAM above 4 GB?
I've read the white paper, "Planning for Scalability and Performance with Reporting Services" (http://www.microsoft.com/technet/prodtechnol/sql/2005/pspsqlrs.mspx) which briefly (but incompletely) discusses 32 vs 64 bit, and really doesn't touch on RAM at all.
Thanks for any pointers,
Scott

Hello,
We are establishing a database server for our product suite containg 14 products- these products is basically intended to be used by CAs and Accountants.
my databaseserver will have 14 databases-
4 are very small, 4 are complex and 6 are Very complex- there is a close intraction between all these databases.
at any time there will be around 500 users using these products but since these products are seasonal there is a chance that all 500 users are connected to one database only.(but there is also a possiblity that load is equally distributed on all the databases)
My product will run on intranat.
My requirement is:
1. What is best server configuration for hosting such type of database.(sqlserver 2005)
2. How many concurrent users sqlserver supports(MSaccess supports 15 concurrent users)
3. I want that if user has license for 10 users my Database should bear load of only 10 user.

HiI joined a project where 100,000 rows were added everyday. Now due toadditional customers the expectation is 2 million reocrds/day ie 10 GB worthof textfiles. We have to estimate the hard disk, memory, # of CPUs etc.Wewill have one yearworth of data in the db. Rest will be in tapes etc.We will be using WIN2000, SQL Server2000.- Any comparable server sizing willbe appreciated.1. Tohandle every day load, I thought that we will have a table for each day(pre created in the database )and have a view with union all selectingfromall these 365 tables. (This is the only way to partition in MSSQL Serverright?).2. The requirement is to populate datawarehouse tables with all the data.However there will be only inserts mostly but there can be updates too whichhappenned in the past 12 days.Hence we have to use the data from the last12 days and massage it etc and populate into datawarehouse tables.How can I do this so that I will have the datawarehouse tables with n-12days of data and I will alwys add the last 12 days data to it.Do you have any suggestions?Ragu

Hello,
I have been working on SQL Server Capacity Planning for a few weeks now and have gathered a lot of materials, but non of thes materials contain recommended best practices on SQL Server capacity planning and also they do not contain operational guidelines.
I would be glad if anyone can recommend a website or book that contain information on SQL Server Capacity Planning Best Practices.
Thanks,

I cannot think of any reason, in our environment, why I would recover the model database. Change framework has all databases coming from DEV & QA before landing on PROD. We have never used the model database as framework of new databases either.
So, if I discontinued backup of the database, what is my recovery method if it become corrupt? Since mine is not used, can I simply copy it from another server?

I was browsing Microsoft's SQL Server site, looking forsome details about SQL Server 2005. Didn't find whatI was looking for...I'm thinking about moving an existing SQL Server 2000workload to a new box, using SQL Server 2005, andmaybe the 64-bit version.My questions are:1. What is the current target date for release of SQL Server 2005?Will 64-bit ship when 32-bit ships?2. Will 64-bit SQL Server 2005 require a special versionof Windows Server 2003 (e.g. Windows Server 2003 Enterprise x64)?Will it work with both Intel and AMD processors?3. How many CPUs, and how much memory, will be supported bySQL Server 2005, 32-bit and 64-bit, on each OS that can runSQL Server 2005.I'm looking for a chart here, something like the chart onpage 117 of Kalen Delaney's "Inside SQL Server 2000" book.SQL Server 2005 SQL Server 2005Feature Enterprise 32-bit Enterprise 64-bit------------------- ----------------- -----------------CPUs supportedWin Srvr 2003:Win Srvr 2003 Adv:Win Srvr 2003 Ent x64:Physical memorysupportedWin Srvr 2003:Win Srvr 2003 Adv:Win Srvr 2003 Ent x64:Has Microsoft published this info, and I just can find it?

Here are my planning details:
RAID 1:
2 disks RAID 1 for OS and BINS
2 disks RAID 1 for Backups.
RAID 10
4 disks RAID 10 for data
4 disks RAID 10 for log
4 disks RAID 10 for TEMPDB
Should i put the master and other system database on RAID 10 along with TempDB.
Or what else a guru fellow will advise in above setup.
thanks,

I am in the process of formulating recommendations with respect to the purchase of additional storage for our current SQL 2012 SharePoint (2013) instance. My recommendation is to purchase separate storage (i.e, 15k disks) for the TempDB and Tlogs respectively (two sets of raid 10 disks). Currently, this server is hosting several instances, including SP, using two arrays (one for database and the other for Tlogs).
I am attempting to find information/recommendations on how to go about projecting the amount of storage for each of these while factoring in for growth.
Additional Details:
how to best formulate a reasonable estimate. Our largest content database belongs to IT and is currently ~80GB. That said, this is currently an outlier. The remaining content databases are less than 10GB (most are less than 2-3 GB). However, SharePoint will be used for digital document imaging in addition to, eventually, replacing file shares as our primary document storage medium once we roll it out.
Our current tempDB is ~400MB, but the instance was recently started a few days ago, as we had to failover to our backup server for hardware maintenance. I do not have any historical data on TempDB growth at this time. Also, I don't know how useful this would be given we have not fully deployed yet.

Is there any way to copy my Data of 2015 to the Planning/Forecasting Value of 2016?
My question is based on that we use INFOR ION BI right now and there we can just add an Button in our reports wich physically copies the value from one year to the next year based on some other rules in the cube.
Now I need to make this example work with SSAS and Excel PivotTables but I cant figure out how.
I have absolutely no clue where and how to accomplish it. Do I use Calculations, do I use Actions, do i make it in the Dataview, Cube or directly in Excel?
