How to use Browsing Index

Hi, I want to speed up a search that return a large number of users. For what I understood I need to create a Browsing index. I've created a browsing index following instruction on the Admin manual, but I really don't understand how to use it ?
After creating the index (ldapmodify + vlvindex), are this index used by default if the search mach the vlvbase and vlvfilter ?
Thanx

Sorry I don't know why I don't see the [notes=u] in the access log but it seam the my vlv is not created at all.
When i run vlvindex I get the following error:
[18/Feb/2005:12:28:01 +0100] - userRoot: Indexing VLV: Sort SN
[18/Feb/2005:12:28:02 +0100] - userRoot: Indexed search unsuccessful, will perform unindexed search instead.
No vlv#.... files are created in the db directory, so I think no vlv index are created..

How to use secondry index

Hi Experts,
I have a requirement to improve the performance of report,So i got some select querys there non primery keys are used for table VBAK,VBAP,LIKP,LIPS so i want to create secondry index for that,Any one can help me for that means after create secondry index how to use that index in report and for create secondry index required any MANDT field or Not.
Thanks.

Hello Ram,
Before creating secondary index you need to know the below points.
1) Do not create more indices on table
2) What is the frequency of table access
3) You should not create too much columns(should be less than 120 characters)
4) Cant you use existing indices?
5) DML operation will be delayed if you create index
Before moving to Production system please consider below the points.
1) Ask BASIS to create index in DB level then move your DDIC transport which will be faster
2) While creating index if the DB size is like more than 500 GB then downtime is required

How to use cfloop index value as part of another variable

Hello,
I have a RATE form that first asks "how many rates will you
be adding?" that answer generates a series of form elements based
on the answer. You then have a form grid to populate, 3 values for
each rate (price, code, name).
This part works fine. The issue is now I need to INSERT the
values into the table, so I need to use the INDEX value of the
cfloop to recreate the amount (and names) of the fields in the
INSERT statement. How do I escape, or re-create the evaluated form
elements ( in which their count is #i# as the loop goes) when I
need to evaluate for #i# AND evaluate for #form.sku_i_name# at the
same pass?
I am passing, for example, #form.sku_2_Name# where that might
equal "Half Page". The number 2 in that variable was assigned
during the form creation by the current index of a cfloop. Since my
action (insert) page does not know how many (out of 50 possible)
sku's are coming, how do I use the skuCount (another hidden value
passed as well) to create a proper INSERT SQL command when I need
to eval the form element and the index at the same time?
Obviously #sku_#i#_Name# does not work, and #sku_i_Name# does
not either... I know this can be done, and that I am just doing it
wrong.
Thanks for any help!

how it works
As all three of us indicated you use array notation for this
type of
requirement. In ColdFusion you can use array notation or dot
notation
to access structure data. Almost all data in ColdFusion is
now some
type of structure.
I.E. #Form['myField']# is the same as #Form.myField#.
The advantage is that with array notation you can do things
you can not
do with dot notation. You can reference elements that have
keys that
are illegal variable names such as one with a space.
I.E. #url['my field'] is allowed, #url.my field# would fail
or course.
And you can concatenate the key string as we did with your
example.
I.E. #Form['aString' & aVariable]#
There are many powerful things one can do with this
knowledge. One can
access record sets with array notations. This can allow for
very
sophisticated parsing of a record set.
I.E. #myQuery['column'][row]#
You can dynamical call a variable. Thus creating dynamic code
that does
not even need to know what variables exist until run time.
I.E. #variables[anyName]#
This just scratches the surface.

How to use an index

Hi,
Can someone tell me how can I use a index of row?
I want to see if any value is repeated in a column something like
declare
x number;
type my_table is table of number;
var_c1 my_table;
begin
for i in 1..6 loop
select round(dbms_random.value(1, 49),0) bulk collect into var_c1 from dual;
if var_c1(i) = var_c1(i).next then
dbms_output.put_line(var_c1(1));
end if;
end loop;
end;
thank you

I am sorry but I do not understand the question.
If you want to see if each row is unique just try and create a unique index on the column or select column_name, count(column_name) group by column_name order by 2 or something similar.

How to use search index created by jhindexer

Hi i have created a JavaHelp set using Docbook which works ok but the search doesnt work. I then discovered jhindexer and have sucessfully used it to create a directory called index containing the index (DOCs,DOCS.TAB etc) in the same directory as the html files but it still doesnt work.
I guess i have to modify one off my javaHelp files (jhelpidx.xml,jhelpset.hs) to point to this index but cant find any info on this.
Can anyne help me please.

place the snippet below into your HelpSet File (.hs), the helpset file should be in the same directory as the JavaHelpSearch folder where your index files are located. See the structure:
/foo.hs
/JavaHelpSearch/DOCS
/JavaHelpSearch/OFFSETS
---- snippet -----
<view>
<name>Search</name>
<label>Suche</label>
<type>javax.help.SearchView</type>
<data engine="com.sun.java.help.search.DefaultSearchEngine">JavaHelpSearch</data>
</view>
---- snippet -----
And read the supplied PDF documentation, because if you have problems with this, you will have even more problems with some more advanced stuff.

Browsing index

Hi,
I'm trying to use browsing index to improve the performance of a search but I don't get any result.
To configure the browsin index I have added the two entries:
dn: cn=Cache, cn=userRoot,cn=ldbm database,cn=plugins,cn=config
objectClass: top
objectClass: vlvSearch
cn: Cache
vlvbase: ou=xxxxx,o=yyyyy,c=es
vlvscope: 1
vlvfilter: (|(att1=value1)(|(attr2=val2)(attr3=val3)))
dn: cn=Telephone, cn=Cache,cn=userRoot,cn=ldbm database,cn=plugins,cn=config
objectClass: top
objectClass: vlvIndex
cn: Telephone
vlvSort: authcallingstationid
So, what I would like the LDAP server to return are the authcallingstationid attribute of those entries that match the vlvfilter.
and the search I'm doing is:
./ldapsearch -1 -T -S authcallingstationid -G 30:30:authcallingstationid -x -h <ldapserver> -p <port> -D "uid=user" -w <pasword> -b "ou=yyyyy,o=xxxxx,c=es" -s one '(|(att1=value1)(|(attr2=val2)(attr3=val3)))' authcallingstationid
In the error log it doesn't appear the message:
[13/Mar/2007:15:52:40 +0100] - WARNING<20805> - Backend Database - conn=30 op=1 msgId=2 - search is not indexed
so I guess it is using in some way the index. But I don't get any performace improvement.
Am I using in a wrong way the browsing index?.
Thanks.
Regards,
David.

Hi David,
Once you had defined the 2 entries for the Browsing Index, have you rebuilt the indexes for the database ?
You can either use db2index or export and re-import the data.

How to make an index use in a query execution

Hi,
I have the below query for which ename column has an index. As of my knowledge below queries 1st and 2st will not use index. Hence i used the 3rd statement and that too its not using the index. Finally i used the 4th query, but even the 4th query is not using the index. Then how do i make this query to use my index??? Do i need to create a function based index for this??? Is that the final option????
1. select * from emp where ename !='BH' ;
2. select * from emp where ename <> 'BH';
3. select * from emp where ename not in ('BH');
4. select * from emp where ename < 'BH' or ename > 'BH';

Sorry 007, I really thought you were posting a trick question as on the OCP tests.
Anyway, as Justin mentioned, if you have an index on ename, it may be used when doing a comparison predicate statement with the ename value.
What it depends on are several other things: stats, how many rows in the table, use of an index hint, etc.
Rather than questioning the group on this, why not just turn on autotrace and run the query for the different scenarios.
The output will show you if it used the index, number of rows returned, blocks read, etc.
SQL> create table emp (ename varchar2(40));
Table created.
SQL> insert into emp select username from sys.dba_users;
25 rows created.
SQL> commit;
Commit complete.
SQL> set autotrace on
SQL> select * from emp where ename != 'SYSTEM';

How to make an index in InDesign CC 2014.1 using a topics list?

Hi all,
I have read the long help document on how to make an index in InDesign CC 2014.1 using a topics list, and still can't work out what to do.
I have done a 548 page book, using a document for each chapter, and a book file to put them all together in the right order.
I now need to make an index at the back, as the author has many quotes throughout the book at the start of each chapter and section.
I have a list of those people quoted and want to upload this list and get the index feature in InDesign to find all instances of the name occurring in the entire book.
After reading the help document I still cannot work out how to do this.
My questions are:
1. Do you have to use an InDesign document as a source for the list of topics? If so, should the document be added to the book file or outside it?
It seems a bit recursive to have the list of topics in an ID document that is in the book file.
2. Once you have uploaded the topics into the Index feature, how do you get it to look for all instances of that 'topic' througout the entire book? I can't figure that out from the help documents. What do I select? Do I do it from the Index panel? Do I highlight the text in the source document? Not sure how to do this...
3. I need the names to list surname first of the quoted authors in the index. This command seems to be different between various editions of ID. For ID CC 2014.1 is it ctrl+alt+shift+]
4. To make the surname show first, what do I highlight? The topic? and then do ctrl+alt+shift+] and select find all as well? Or do I have to just go through the text and manually do this and ditch the idea of uploading topics first?
I am confused as you can see and any help with this is appreciated.

How do I use the Index Values property node with a multidimensional array.

I am using a 2D array to store operator inputs on my front panel. I only want to display one element to the operator at a time. I am trying to use the Index Values property node to change the displayed element. However, I can only get the Rows index to work. How do I direct the Columns index as well? The help says to use one per dimension. I need clarification on what this is talking about. I've tried adding a second element to the property node, 2 seperate property nodes, and diferent wiring techniques. (series, parallel)

If you only wire up one of the inputs (col or row) what you get out is a 1D array of either the column or row. If you wire controls to both, then you will get one element out of the array. Getting a single element in a 2D array requires you to specify both a row and column.
