Need some helpon index creation

Hi,
I am having a table with 2 billion records and I am having a partition (based on date) and sub partition (based on hours). Mainly I will be selecting some records based on some conditions and I will be using rollup function in my query, I will not be doing any DML operation on this table.
Whether we have to use any index on this table for improving the performance or not required while doing group by and rollup...? Also since I am not going to do any DML operation on this table I thought of using bit map index. Please help me out on this, I am very new to index concepts.
table desc:
SIGNRTS Date Stamp
position_step Char 10
Camp_id Char 40
Camp_Info BLOB
Sp_id Big int
Dom_col Char 8
Count Long int
In_Count Int
Tot_ser Long int
Tot_impr Long Int
Flag Short int
We have primary key for SIGNRTS,position_step,camp_id,camp_info,sp_id.
Thanks

So this now means that all queries that have:
where Signrts = ... some value...Should only be accessing the (sub) partitions that could have rows of interest in them.
Good.

"Based on some conditions" is the crucial determinant here. It all depends on the conditions that you are going to use, that combined with the given partitioning scheme you gave us, will determine whether additional (local) indexes are usefull or not.

Need help troubleshooting Index creation..

Hi,
I'm using RH8, Webhelp, working locally.
I've tried several times to create an index, but each time it crashes.
The first few times, I manually accepted the index keywords.....I'd spend about 25 minutes or so working on it, then RH would freeze on random files (different each time), causing me to reboot RH. I've lost the entire index because it never completed.
Now, I thought I would test it by just automatically adding the index keywords.......and after about 3-4 minutes of it working through the files, it froze. I can't even minimize the RH window, I have to reboot again.
I've created an index for a previous project with no errors......but this is not the case with this project.
Does anyone have any advice on what could be wrong? Anything errors I can eliminate? files to test? review? anything? I don't even know where to begin to troubleshoot this problem.......
Thanks!

HI,
Just following up....
1 - Yes, I have successfully created an index on a completely different project.
2 - Windows xp, 32.
I need to revisit this issue in a couple of months, I have other things to tend to. I'll post back my "next attempts" on creating an index.
but, if there's someone out there with an answer, by all means.........please share!
Thanks!

Need some help in creation of a VM image

Hi, we have been tasked with the creation of a VM image which has WebLogic Server, Coherence, Oracle Database XE etc. And I am a newbie to it Do you have any tips to help me get started?? Thanks and regards Anil

I never tried it, but when you're booting from a OVMs 3.2.7 CD you can choose the p2vm option, which I assume, would convert your installation into a guest fpr OVM.
Maybe you should read up on that in the OVM documentation.

Systemcopy using R3load - Index creation VERY slow

We exported a BW 7.0 system using R3load (newest tools and SMIGR_CREATE_DDL) and now importing it into the target system.
Source database size is ~ 800 GB.
The export was running a bit more than 20 hours using 16 parallel processes. The import is still running with the last R3load process. Checking the logs I found out that it's creating indexes on various tables:
(DB) INFO: /BI0/F0TCT_C02~150 created#20100423052851
(DB) INFO: /BIC/B0000530000KE created#20100423071501

(DB) INFO: /BIC/AODS_FA00~010 created#20100423121754
As one can see on the timestamps the creation of one index can take an hour or more.
x_cons is showing constant CrIndex reading in parallel, however, the througput is not more than 1 - 2 MB/sec. Those index creation processes are running now since over two days (> 48 hours) and since the .TSK files don't mentioned those indexes any more I wonder how many of them are to be created and how long this will take.
The whole import was started at "2010-04-20 12:19:08" (according to import_monitor.log) so running now since more than three days with four parallel processes. Target machine has 4 CPUs and 16 GB RAM (CACHE_SIZE is 10 GB). The machine is idling though with 98 - 99 %.
I have three questions:
- why does index creation take such a long time? I'm aware of the fact, that the cache may not be big enough to take all the data but that speed is far from being acceptable. Doing a Unicode migration, even in parallel, will lead to a downtime that may not be acceptable by the business.
- why are the indexes not created first and then filled with the data? Each savepoint may take longer but I don't think that it will take that long.
- how to find out which indexes are still to be created and how to estimate the avg. runtime of that?

i Peter,
I would suggest creating an SAP ticket for this, because these kind of problems are quite difficult to analyze.
But let me describe the index creation within MaxDB. If only one index creation process is active, MaxDB can use multiple Server Tasks (one for each Data Volume) to possibly increase the I/O throughput. This means the more Data Volumes you have configured, the faster the parallel index creation process should be. However, this hugely depends on your I/O system being able to handle an increasing amount of read/write requests in parallel. If one index creation process is running using parallel Server tasks, all further indexes to be created at that time can only utilize one single User Task for the I/O.
The R3load import process assumes that the indexes can be created fast, if all necessary base table data is still present in the Data Cache. This mostly applies to small tables up to table sizes that take up a certain amount of the Data Cache. All indexes for these tables are created right after the table has been imported to make use of the fact, that all the needed data for index creation is still in the cache. Many idexes may be created simultaneously here, but only one index at a time can use parallel Server Tasks.
If a table is too large in relation to the total database size, then its indexes are being queued for serial index creation to be started when all tables were imported. The idea is that the needed base table data would likely have been flushed out of the Data Cache already and so there is additional I/O necessary rereading that table for index creation. And this additional I/O would greatly benefit from parallel Server Tasks accessing the Data Volumes. For this reason, the indexes that are to be created at the end are queued and serialized to ensure that only one index creation process is active at a time.
Now you mentioned that the index creation process takes a lot of time. I would suggest (besides opening an OSS ticket) to start the MaxDB tool 'Database Analyzer' with an interval of 60 seconds configured during the whole import. In addition, you should activate the 'time measurement' to get a reading on the I/O times. Plus, ensure that you have many Data Volumes configured and that your I/O system can handle that additional loag. E.g. it would make no sense to have 25 Server Tasks all writing to a single local disk, I would assume that the disk would become a bottle neck...
Hope my reply was not too confusing,

Help needed in index creation and its impact on insertion of records

Hi All,
I have a situation like this, and the process involves 4 tables.
Among the 4 tables, 2 tables have around 30 columns each, and the other 2 has 15 columns each.
This process contains validation and insert procedure.
I have already created some 8 index for one table, and an average of around 3 index on other tables.
Now the situation is like, i have a select statement in validation procedure, which involves select statement based on all the 4 tables.
When i try to run that select statement, it takes around 30 secs, and when checked for plan, it takes around 21k memory.
Now, i am in a situation to create new index for all the table for the purpose of this select statement.
The no.of times this select statement executes, is like, for around 1000 times of insert into table, 200 times this select statement gets executed, and the record count of these tables would be around one crore.
Will the no.of index created in a table impacts insert statement performace, or can we create as many index as we want in a table ? Which is the best practise ?
Please guide me in this !!!
Regards,
Shivakumar A

Hi,
index creation will most definitely impact your DML performance because when inserting into the table you'll have to update index entries as well. Typically it's a small overhead that is acceptable in most situations, but the only way to say definitively whether or not it is acceptable to you is by testing. Set up some tests, measure performance of some typical selects, updates and inserts with and without an index, and you will have some data to base your decision on.
Best regards,
Nikolay

Fast index creation suggestions wanted

Hi:
I've loaded a table with a little over 100,000,000 records. The table has several indexes which I must now create. Need to do this as fast as possible.
I've read the excellent article by Don Burleson (http://www.dba-oracle.com/oracle_tips_index_speed.htm) but still have a few questions.
1) If the table is not partitioned, does it still make sense to use "parallel"?
2) The digit(s) following "compress" indicate the number of consective columns at the head of the index that have duplicates. True?
3) How will the compressed index effect query performance (vs not compressed) down the line?
4) In the future I will be doing lots and lots of updates on the indexed columns of the records as well as lots of record deletes and inserts into/out-of the table. Will these updates/inserts/deletes run faster or slower given that the indexes are compressed vs if they were not?
5) In order to speed up the sorting, is it better to add datafiles to the TEMP table or create more TEMP tables (remember, running "parallel")
Thanks in Advance

There are people who would argue that excellent and Mr. Burleson do not belong in the same sentence.
1) Yes, you can still use parallel (and nologging) to create the index, but don't expect 20 - 30 times faster index creation.
2) It is the number of columns to compress by, they may not neccesarily have duplicates. For a unique index the default is number of columns - 1, for a non-unique index the default is the number of columns.
3) If you do a lot of range scans or fast full index scans on that index, then you may see some performance benefit from reading fewer blocks. If the index is mostly used in equality predicates, then the performance benefit will likely be minimal.
4) It really depends on too many factors to predict. The performance of inserts, updates and deletes will be either
A) Slower
B) The same
C) Faster
5) If you are on 10G, then I would look at temporary tablespace groups which can be beneficial for parallel operations. If not, then allocate as much memory as possible to sort_area_size to minimize disk sorts, and add space to your temporary tablespace to avoid unable to extend. Adding additional temporary tablespaces will not help because a user can only use one temporary tablespace at a time, and parallel index creation is only one user.
You might want to do some searching at Tom Kyte's site http://asktom.oracle.com for some more responsible answers. Tom and Don have had their disagreements in the past, and in most of them, my money would be on Tom to be corerct.

CONTEXT index creation - performance!

Hi,
I have a table with about 5Million rows. The content that needs to be indexed is of RAW datatype. The average size (length) of this field is about 50 characters (it could be more).
I am trying to index this column to perform a keyword search. DEtails are furnished below.
table:
SQL> desc kwtai
Name Null? Type
TSD_HH24 DATE
COUNTRY_CODE_ALPHA_2 VARCHAR2(2)
ONETWORK NUMBER(6)
OADDRESS VARCHAR2(25)
DNETWORK NUMBER(6)
DADDRESS VARCHAR2(25)
MESSAGE_LENGTH NUMBER
MESSAGE_CONTENT RAW(2000)
Preferences:-
begin
Ctx_Ddl.Create_Preference('mc_storage', 'BASIC_STORAGE');
ctx_ddl.set_attribute('mc_storage','I_TABLE_CLAUSE',
'tablespace large_index storage (initial 10M next 10M)');
ctx_ddl.set_attribute('mc_storage', 'K_TABLE_CLAUSE',
'tablespace large_index storage (initial 10M next 10M)');
ctx_ddl.set_attribute('mc_storage', 'R_TABLE_CLAUSE',
'tablespace large_index storage (initial 1M) lob (data) store as (cache)');
ctx_ddl.set_attribute('mc_storage', 'N_TABLE_CLAUSE',

end;
create index kwtaidx on kwtai (message_content) indextype is ctxsys.context
parameters (' lexer mc_lex storage mc_storage memory 500M ')
parallel 16;
This create index takes about 4 hours to complete on a 8CPU dual core machine.
This is on Oracle 10g (10.2.0.4)
The reason i am creating the index as opposed to syncing it is because the data gets loaded into this table only once a day and it gets cleared once my keyword analysis is done.
Any pointers to speed up the index creation will be really appreciated! Thanks in advance!

My base table has the text that needs to be indexed stored in the "MESSAGE_CONTENT" column which for now is RAW data type. The data stored in this table are in hex representation.
Some examples -
MESSAGE_CONTENT
616C70686120626574612067616D6D612064656C746120657073696C6F6E207A657461206E69F16F

Now with your suggestion i tried to bypass this. So what i did was added a format column to my base table and updated it to "TEXT". My database is in UTF8.
Now when i create the index with the following preferences it takes less than a minute.
begin
Ctx_Ddl.Create_Preference('kwta_storage', 'BASIC_STORAGE');
ctx_ddl.set_attribute('kwta_storage','I_TABLE_CLAUSE',
'tablespace TEXT_INDEX storage (initial 10M next 10M)');
ctx_ddl.set_attribute('kwta_storage', 'K_TABLE_CLAUSE',
'tablespace TEXT_INDEX storage (initial 10M next 10M)');
ctx_ddl.set_attribute('kwta_storage', 'R_TABLE_CLAUSE',
'tablespace TEXT_INDEX storage (initial 1M) lob (data) store as (cache)');
ctx_ddl.set_attribute('kwta_storage', 'N_TABLE_CLAUSE',
'tablespace TEXT_INDEX storage (initial 1M)');
ctx_ddl.set_attribute('kwta_storage', 'I_INDEX_CLAUSE',
'tablespace TEXT_INDEX storage (initial 1M) compress 2');
ctx_ddl.create_preference('mylex', 'BASIC_LEXER');
ctx_ddl.set_attribute('mylex', 'skipjoins', '_-"''`~!@#$%^&*()+=|}{[]\:;<>?/,');
ctx_ddl.set_attribute('mylex','punctuations','.?!');
ctx_ddl.set_attribute('mylex', 'INDEX_STEMS','NONE');
ctx_ddl.set_attribute('mylex', 'continuation','\-');
Ctx_Ddl.Create_Stoplist ( 'mystop' );
Ctx_Ddl.Add_Stopword ( 'mystop', 'is' );
Ctx_Ddl.Add_Stopword ( 'mystop', 'has' );
Ctx_Ddl.Add_Stopword ( 'mystop', 'the' );
Ctx_Ddl.Add_Stopword ( 'mystop', 'that' );
end;
create index kwtaidx on kwtai (message_content) indextype is ctxsys.context
parameters ('filter ctxsys.auto_filter format column fmt stoplist mystop lexer mylex storage kwta_storage memory 500M')
parallel 16;
When i select distinct tokens from the $I table i get the following
TOKEN_TEXT
RESTAURANT
GREEK
WHATS

DELTA
ZETA

ALPHABET
EPSILON
PF
PSEDUOCOOL
SOME
CHANGS
NIÃO
ON
POSTDATA
SCRIPT

GAMMA
GOING
HEY

Now what i am also wondering is if the text (message_content column) is being converted to UTF8 (database characterset) by using AUTO_FILTER. Is my assumption correct? Not sure how to validate this?
And, would you kindly share of why RAW must not be used in this case?
Thanks for all your pointers!

Why index creation is slower on the new server?

Hi there,
Here is a bit of background/env info:
Existing prod server (physical): Oracle 10gR2 10.2.0.5.8 on ASM
RAM: 96GB
CPUs: 8
RHEL 5.8 64bit
Database size around 2TB
New server:
VMWare VM with Oracle 10gR2 10.2.0.5.8 on ASM
RAM 128GB
vCPUs: 16
RHEL 5.8 64bit
Copy of prod DB (from above server) - all init param are the same
I noticed that Index creation is slower on this server. I ran following query:
SELECT name c1, cnt c2, DECODE (total, 0, 0, ROUND (cnt * 100 / total)) c3
FROM (SELECT name, VALUE cnt, (SUM (VALUE) OVER ()) total
FROM v$sysstat
WHERE name LIKE 'workarea exec%')
C1
C2
C3
workarea executions - optimal
100427285
100
workarea executions - onepass
2427
0
workarea executions - multipass
0
0
Following bitmap index takes around 40mins in prod server while it takes around 2Hrs on the VM.
CREATE BITMAP INDEX MY_IDX ON
MY_HIST(PROD_YN) TABLESPACE TS_IDX PCTFREE 10
STORAGE(INITIAL 12582912 NEXT 12582912 PCTINCREASE 0 ) NOLOGGING
This index is created during a batch-process and the dev team is complaining of slowness of the batch on new server. I have found this one statement responsible for some of the grief. There may be more and I am investigating.
I know that adding "parallel" option may speedup but I want find out why is it slow on the new server.
I tried creating a simple index on a large table and it took 2min in prod and 3.5min on this VM. So I guess index creation is slower on this VM in general. DMLs (select/insert/delete/update) seem to work with better elapsed time.
Any clues what might be causing this slowness in index creation?
Best regards

I have been told that the SAN in use by the VM has capacity of 10K IOPS. Not sure of this info helps. I don't know more than this about the storage.
What else do I need to find out? Please let me know - I'll check with my Sys Admin and update the thread.
Best regards

BIA Index creation error due to invalid characters

Hi All,
While creating BIA index on an Infocube the index creation process fails with the following message.
Index for table '/BIC/SSPSEGTXT' is being processed
A character set conversion is not possible.
Parallel indexing process terminated (Task: '4')
Turns out this field is a text field and has characters such as * and + in the description,which is causing this problem.
How do I proceed with the index creation.
Options I have are:
a) Get rid of this field.. Impossible since there are a few queries that require this information.
b) Run the Database scan tool RSI18N_Search to eliminate foreign characters ....but this does not work for me.
Can anyone suggest some other option or a resolution to this problem. Or If anyone has prior experience of working with the program RSI18N_Search please let me know.
Regards
VK

Venkat, Andres,
You can try several things here;
1) This is pretty ugly but in case you need a quick way around. Create another cube w/o that char, load all the data to that cube from the first cube, and start sending daily deltas to both cubes. Of course put the second cube to BWA
2) Delete the master data! When you try deleting the master data (a particular record or records that you identified), mostly you will find out that it's used in a transactional data(in ODS or Cube) therefore it will not allow you to delete those records, unless you delete the records from the cubes first, then try it again. OR you might be lucky that it's not stored in anycube and it will delete it right away!
The right way is the second option, however when you delete data from cubes, ods, it will lock the cube + invalidate aggregates if you have + BWA indexes etc. You need to recreate them again. So try doing it in non-business hours or in your maintenance window.
Cheers
Tansu

Status of Fulltext Index Creation Process

Greetings!
We are creating a fulltext index over a jdbc/java call. We need to wait for the index creation to complete. How can I tell when the process is complete?
Thanks!
Mukunda

Thanks Markus!
We did some testing..The index entries are inserted into SYS.M_FULLTEXT_QUEUES when the index process is started and not when it is ended.
This table provides information such as document, indexed_document, queue_document, error_document counts. Am I missing something?

I do this all the time, I put my MBP to a 60 inch Sharp. If you have the video working do the simple thing first. Check to make sure your sound is on your TV and Mac. Then if that doesn't work go to System Prefrences and under sound go to a tab called Output and see if your TV is listed and if it is change it to that setting
Hope It Works

Need User Exits for Creation of Delivery and for Posting Goods Issue

Hi,
I need User Exits for
Creation of Delivery
Posting Goods Issue
I need to make some checks regarding customer license expiration and if checks fail, I need to stop Creation of Delivery and Posting Goods Issue.
Thanks in advance,
Will reward,
Mindaugas

In the delivery you can use userexit USEREXIT_SAVE_DOCUMENT_PREPARE to make your checks and send an error message to the user in case they fail.
You can find this user exit (form routine) in include MV50AFZ1.
Hope that helps,
Michael

Index creation failed in Business Objects Explorer

Hi,
I installed the Business Objects Explorer ...
But I can not index anything.
When I try to index the following message appears:
"Server, DRWBI001.PolestarIndexing, generated messages The Following:

What should I do? help me please

I do not have UNIVERSE.
I'm trying to index files like Microsoft excel.
I have to do some configuration in the CMC to be able to crawl in Business Objects Explorer?

Need suggestion on indexes

I want to create some indexes on following table in Oracle 10G database.
Table --> RegionalOrders
Columns -->
TenorderID -- PrimaryKey
custid number(6) -- ForegionKey
Empid number(6)-- ForegionKey
Region (char(4)) -- ForegionKey
Tencon varchar(20),
Tensell varchar(20),
Tendate date
Following are some of heavy activties on this table :
1) Ofter joins
2) Joins mostly based on primary key and foreigh key
I have following queries regarding indexes on this table.
a) can you please suggest what columns I can index.
b) There is not need to create index on TenorderID ( as its primary key)
c) Can we create any indexes for table joins.

I guess that will be not a very good approach to create indexes like this. If you have queries with you that you are going to write over this table and other table(s) ,looking at explain plan of them , it wil be more accurate to tell which column(s) should be indexed. Remeber , index based on a single query's performance are not of much use and will lead to more issues than benefits.
You are correct in saying that PK column is not required to be indexed.Table join indexes or anything like that is not there,you can create indexes on underlying colums.
