Fill Factor

Aug 13, 2001

I am really confused about this whole fill factor thing. The way I understand it, is if you have a table whose data remains pretty much static, you should use a higher fill factor. Suppose you had a database where you had at most 150 transactions a day that changed the data, should the fill factor be left at the default(0) or increased? How do you determine how much to increase it? Is there a rule of thumb that suggests if you have x number of changes against a table, you should have a fill factor between y and z percent?

Please Help

Fill Factor Fix

Apr 3, 2001

Currently we have tables (in sql 6,5), many of them do not have primary keys.
While I was trying to re-index (re-org), many of them got an error:
"fillfactor 204 is not a valid percentage; fillfactor must be between 1 and 100."
(many tables' fillfactor exceed 100 or more...)
How can I fix them so I can upgrade to sql 7 ?
Thank you for your help.

Fill Factor

Mar 12, 2001

Hi all,
While creating indexes for a table, I specified a fill factor of 70%. I then inserted a few hundred rows into the table. Is it possible to check to what percent the pages are full after the rows have been inserted?

Thanks in advance,

Fill Factor

Jul 13, 2007

Hi experts, I would like to ask regarding FILL FACTOR. I observed that our system's loading is a bit slow, and some of the modules take 1 to 2 minutes loading. Maintenance activity is regularly executed based on the scheduled sets. Then I tried to checked the tables indexes/keys turns out that the FILL FACTOR is set to ZERO(0). I would like to know if the FILL FACTOR set to zero will be a factor for the system to slow down..????

Index Fill Factor > 100 !!

Sep 14, 1998

I have some non-clustered , non-unique indexes on a medium sized table (25,000 rows).
The fill factore is showing 248% on these indexes. I have tried setting the fill factor to various values 100% or less. The re build index seems to work, however the est min/avg/max size of the index all show appx 160Kb, whilst the actual size is in excess of 50Mb !!

We run a weekly rebuild of all indexes overnight, without any fill params and following this the fill on these indexes goes back to 248% !

I have also dropped and re-created the index with a fill of 100%, and it has still reverted to 248% following the weekly rebuild.

I have also looked at the server config, and the fill factor there shows a running value of 171% !!, although the current config is set to 0.

The server is stopped every evening, so no way should the config have a value of 171, especially since the max allowed value is 100.

Any advice/assistance would be gratefully received.

Fill Factor In Indexing

Feb 21, 2008

Hi there

Is there any such thing that you can find the current Fill Factor for each indexing? The only thing that you have an indication is by looking at DBCC SHOWCONTIF > Scan Density [Best Count:Actual Count].......: 100.00% [0:0] and if this value is not reaching 100% means may have an issue with fill factor ?!!?

Also, how about SQL2000?

Thanks

Fill Factor Confusion

Jul 31, 2007

Turn away pure key zealots
I have a clustered index that starts with an INT IDENTITY(1,1) column and therefore you can only add data to the end of the cluster. What I'm confused about is the relationship between this and the fill factor. In a normal fill factor scenario you'd be worried about inserts causing page splits but if you can only append to this cluster does this mean I should set the factor to 100% even if I'm expecting a large number of inserts? Basically I don't understand what happens when you run out of space on a page on a B-tree if it's based upon an ever increasing number.

Database Defaulting To Fill Factor = 90

Aug 19, 2002

The tables in my database somehow are getting set with a fill factor of 90. In the properties of the server/Database Setting, the "Fixed" option is unchecked. Last Friday, I reset the each table to have a fill factor of zero, but when I came in today, the tables reset themselves to having a fill factor = 90. Any ideas of why this is happening and how I can stop this? Your help is greatly appreciated.

Clustered Index Fill Factor

Jul 20, 2004

If I have a clustered index on only one column of the table, the column being the primary key and an identity column ( int datatype, Ascending CIDX), then can I go ahead and have the Fill Factor be 100%. I may add more rows at a later date to the table.

Let me know.

SQL Server 2008 :: Fill Factor And SSD Based SAN?

Jun 14, 2015

I am about to rebuild all my indexes on a database that is very heavily fragmented. In looking at the report, seems that 80% or more tables are 90%+ fragmented.

My understanding is that fill value value is used for performance reasons. Our shiny new backend SAN is 100% SSD. If solid state can provide a sub-millisecond response, is fill factor still necessary at the cost of additional space being used used?

SQL 2012 :: Re-Indexed With Wrong Fill Factor And Now All Databases Are Huge

Jan 24, 2015

As the title says I re-indexed all of my databases using the wrong fill factor. Instead of using 90% as the fill factor I misunderstood and set this at 10%. So I believe my databases are now packed with a ton of unused space. The DB sizes should be about 5-6 GB but have since grown to 20-40GB. I am very new to SQL administration and don't know of a safe way to remove this unused space so that my databases return to their normal sizes. The databases do not grow very much at all so the free space is not really that necessary.

Attribute 'importance' Factor

Jan 31, 2008

Is there a way to explicitly assign 'weights' or 'importance' factors to attributes and have that to be considered by the association rules and decision trees algorithms during training? I would like to do so without preprocessing the data (In any case, I can't think on a way to assign weight with preprocessing to boolean attributes like 'smoker')

thanks

ADO.NET 2.0 Slows SP Execution By Large Factor

May 21, 2007

I'm hoping someone will be able to point me in the right direction for solving this problem as i've come a bit stuck.
The Sql Server 2005 Stored Procedure runs in about 3 secs for a small table when run from SQL Management Studio (starting with dbcc freeproccache before execution) but times out when run through ADO.NET on .NET (45 sec timeout).
I've made sure the connection was closed prior to opening and executing the adapter. I'm a bit stuck as where to check next though.
Any ideas greatfully received, Thanks

How To Apply An Inflation Factor Depending On The

Oct 5, 2007

Anybody knows how to apply an inflation factor depending on the date to a measure

The Inflation Factor is (Current Month Rate / X Month Rate)

So lets say for current year the rates are

Jan 121.64

Feb 121.98

March 122.244

April 122.171

For example

If I want to calculate for March I would show a column for January February and March, the column for January would be multiplied by (122.244/121.64) the column for February would be multiplied by (122.244/121.98) and march by one (122.244/122.244)

But in April the factors would be different I would have 4 columns, January February March and April, January amounts would be multiplied by (122.171/121.64) February by (122.171/121.98) March by (122.171/122.244) and April by one (122.171/122.171)

Im using SSAS 2005

Thanks in advance

T-SQL (SS2K8) :: Predefined Size Groups - Factor / Rate Rounding

Sep 9, 2014

When sizing products we use predefined size groups that the users can choose any or all of the sizes from. For example if i size group consisted of sizes (6,8,10) they could use all sizes (6,8,10) or just (6,8) or just (10) if required. Similarly, if a group consisted of (S,M,L,XL) they could choose to only buy (S,L). They cannot choose across groups, so would not be able to choose (6,S)

Once the required sizing is determined they then assign size mixes to the sizes to denote how much of the buy will be in that size. So for example if we had 3 sizes: (6,8,10) and they had the associated mixes (25%,25%,50%) that would mean we would buy 25% of size 6 and 50% of size 10. All size mixes must add up to 100% in total.

The users do analysis to determine what sizes they wish to buy and how much of it.

We also have a franchise portion of the business that have some predefined size mixes. They use the same base size groups as above, but the rule is that they can only use sizes that the particular product is being bought in.

So if the assigned franchise mix is S (50%), M (50%) and the main mix was S (100%) then the franchise mix would only be able to then have the S size.

We would then eliminate the sizes from the franchise mix and then to ensure that the franchise mix still adds to 100 we would then pro-rate up the franchise mix to give a new mix. To do this I divide one by the total the remaining size mixes to get a ratio and then multiple the mixes by this factor.

In the case above not be able to use the M size and would only use the S.This would be

-Total of remaining mixes, in this case only size S for simplicity
1 / 0.5 = 2

-multiple original mix by this factor
0.5 * 2 = 1

size S would now be 100% instead of 50%

The issue I'm having is that on occasion some of the totals are adding up to 100.01% because another one of the requirements is that it needs to be 4 decimal places (0.1015 would represent 10.15% in excel)

Here is a shortened version of the code with some test data:

DECLARE @SizeRange TABLE
(
SizeProfileIDINTNOT NULL,
CPCVARCHAR(3)NOT NULL,
SizeNameVARCHAR(5)NOT NULL,
SizeMixDECIMAL(14,4)NOT NULL

[Code] ...

How to get this to round to 4dp and still total 100%?

Fill Problem

Oct 28, 2007

I have one complicated problem with SQL data files. Say that we have four data files:

F1=2000MB
F2=1000MB
F3=3000MB
F4=1500MB

We want to add 3000 MB on these files, and in the same time we want to make the files proportional one with each other:

Will do:

F1 + 500=2500MB
F2 + 1500=2500MB
F4 + 1000=2500MB

With my logic, the final result we’ll be:

F1=2500 MB
F2=2500 MB
F3=3000MB
F4=2500MB

There is an algorithm or a formula to calculate the right value to add to each F1, F2….Fn files having S1, S2….Sn sizes for a T total value to add? Thank you in advance.

P.S. The problem can be complicated when we deal with more than one filegroups and with disk space availability.
