SES and indexing table

Hi
I have a task, to use SES to create intarface (in ABAP) for search in one specyfic table. This table contains field with long description text and I would like to use SES to search over it. I read some documents and i checked SAP Help ... but i still don't know how to start. Is there any step by step tutorial for using SES? Do I have to create Business Object Type for this table? If i have to ... how to create it for to enable SES for it?
Regards
Marcin

Hi Marcin,
I don't know, what you have already read.
The official develper's guide is here:
http://help.sap.com/saphelp_nw70/helpdata/en/43/419742042fc86ae10000000a155106/frameset.htm
-> Business Object Search with Search Engine Service (SES)
Please read the system documentation of the SES ABAP interfaces as well!
Administrator's guide is here:
http://help.sap.com/saphelp_nw70/helpdata/en/27/08ef417fc65f24e10000000a1550b0/frameset.htm
If your task refers to a new entity, you must create you own, new, customer-specific business object type.
You should get access to an ERP 6.0 system, where SES is live for some objects and analyze existing implementations, for example the material master (BUS1001006)
In the customizing you find the implementing class: for material master, it is CL_ERP_SE_BUS1001006.
SES has no problems in handling long fields, containing text.
Maybe you refer to SAPscript long texts. Then have a view at method ADD_TEXT_TO_CONTENT in the above class.
Kind regards, Klaus

Using and Indexing Tables

Hi, I'm fairly new to LabVIEW and had a few questions in regards to a VI I'm building.
I would like to be able to enter in a pressure profile into a table (basically a pressure and time the system stays at that pressure). However, the built-in tables that I've found only use the string format. Is there a standard table for using numeric values, or do I have to build the table from scratch? I could not seem to find a way to format the table to use numeric values.
In addition, I'm trying to use a timer in order to look up the associated pressure value. For instance, if 10 minutes have passed, use that time to look up the pressure from the table. Is this most easily accomplished by indexing? I also saw a look-up table, but was unsure if there is a more appropriate tool to use.
Does anyone have some advice or could you point me in the right direction? Thanks in advance for your time.

Hi drfunkphd,
well a table is just a 2d array of strings...
There are other ways to store your time/pressure pairs. Maybe a 2d array of DBL would be ok? Or an array of clusters of [time, pressure] using different representation for each value?
To look up the pressure by time you have to add up the time values for each pressure value and the use "Threshold 1D Array" to find the index of the pressure value

Confused by the removal of aggregate/index tables in HANA

Hiya,
I've heard that HANA removes the need for aggregate and index tables like BSIS, BSAS, VRPMA etc.
Is HANA smart enough to do this? Or does Simple finance (sFIN) do this?
I mean if we were to replace our Oracle DB with HANA would the index tables no longer exist?
Or would we then need to implement simple finance to then remove the need for index tables?
Thanks in advance!

"HANA is just the DB."
I wouldn't say it's "just" a DB, but for the point we're making here you can say that SAP HANA is mainly used as a DBMS and not as a application platform.
"To remove index tables, aggregate tables etc you can activate business functions through SFW5 to improve specific lines of business."
That's not generally true. Some enhancements (like the VBOX removal) are delivered via enhancement packages. These change the software, but typically don't make a new product out of your system.
"Installation of sFIN, or S/4HANA contain more deeper changes to both the tables and ABAP code - that improve speed and efficiency."
Nope, these are actual new implementations. These are new programs that do similar things as the former NetWeaver programs. But they are newly written code.
This allows for much more radical redesign of functionality leading (hopefully) to even more improvements.
Coming back to your first sentence: the more radical the software changes the more tightly integrated the solution will be with SAP HANA. More and more function will actually run "in" SAP HANA, making it more than just the DB.
Ok, I hope this didn't increase the confusion again.
Cheers,
Lars

DB02 view is empty on Table and Index analyses DB2 9.7 after system copy

Dear All,
I did the Quality refresh by System copy export/import method. ECC6 on HP-UX DB29.7.
After Import Runstats status n Db02 for Table and Index analysis was empty and all value showing '-1'. Eventhough
a) all standard backgrnd job scheduled in sm36
b) Automatic runstats are enabled in db2 parameters
c) Reorgchk all scheduled periodically from db13 and already ran twice.
4) 'reorgchk update statistics on table all' was also ran on db2 level.
but Run stats staus in db02 was not getting updated. Its empty.
Please suggest.
Regards
Vinay

Hi Deepak,
Yes, that is possible (but only offline backup). But for the new features like reclaimable tablespace (to lower the high watermark)
it's better to export/import with systemcopy.
Also with systemcopy you can use index compression.
After backup and restore you can have also reclaimable tablespace, but you have to create new tablespaces
and then work with db6conv and online table move to move one tablespace online to the new one.
Best regards,
Joachim

Table files and Index files 2GB on Windows 2003 Server SP2 32-bit

I'm new to Oracle and I've ran into the problem where my Table files and Index files are > 2GB. I have an Oracle instance running version 10.2.0.3.0. I have a number of tables file and index files that have a current files size of 1.99GB. My Oracle crashes about three times a week because of a "Write Fault/Failure. I've detemined that the RDBM is trying to write a index or table files > 2GB. When this occurs it crashes.
I've been reading the Oracle knowledge base that it suggest that there is a fix or release of Oracle 10g to resolve this problem. However, I've been unable to locate any fix or release to address my issue. Does such a fix or release exist? How do I address this issue? I'm from the world of MS SQL and IBM DB2 and we don't have this issue. I am running and NTFS files system. Could this be issue be related to an Windows Fix?
Surely Oracle can handel databases > 2GB.
Thanks in advance for any help.

After reading your response it appears that my real problem has to do with checking pointing. I've included below a copy of the error message:

Missing Tables and Indexes greyed out in DBACOCKPIT

Hi All,
I use Solution Manager 7.01 with MS SQL Server 2008 DB.
I want to monitor with DBACOCKPIT a MS SQL Server 2005 DataBase of a SAP BPC 5.1.
I connected the DB but in DBACOCKPIT some functionality are greyed out.
I want to use in Diagnostics section the "MISSING TABLES AND INDEXES" function but this command is greyed out.
Is it possible to use this function?
Please, help me!
Regards,
Alessandro

Hi,
Gray color means that screen is disabled for any reason (authorization, SQL Server release, monitoring remote, etc).
I believe, those items cannot be monitored unless these limitations are sorted out.
Please refer to the Document "The SAP DBA Cockpit for Microsoft SQL Server" in SDN.
You can get the status about the restriction in the bottom of dbacockpit screen.

Hi Rakesh,
First thing this is not an issue but an information that says that these indexes are not be created in the System.
This option Indexes not created is an SAP table maintained from Dev to Prod just to indicate that these indexes cannot be created.
That's the reason why u have a green mark beside them and this will make clear for you that this is not an issue.
Hope it helps!!!!
Thanks & Regards,

DB02 = Missing Tables and Indexes = Unknown objects in ABAP Dictionary = DB views

Hi SAP Gurus,
on our SAP NetWeaver 7.x BW (based on AIX/Oracle) I find via transaction DB02 (path = Diagnostics => Missing Tables and Indexes) under "Unknown objects in ABAP Dictionary" under DB views a BW object /BI0/.....
When I make a double click on the object, I am getting the popup window "Display not possible for this object":
How can I identify the object and clarify with the BW application expert, if needed, how to resolve this object?
I searched already via RSA1 for the object, but I wasn't able to find anything so far ...
Thanks for your help and ideas.
Best regards
Carlos

Hello Carlos
The database view in question is a temporary database object created during a query execution.
Please read this SAP note 449891 - Temporary database objects in BW 3.x to understand what that view is all about and impact if those views are removed.
The SAP notes 449891 and 1139396 suggests to run the report SAP_DROP_TMPTABLES to drop these temporary objects. Whether the objects are still required or not is a question to be put across to the BW team. If the temporary objects are removed when they are used by a query, then the query will fail.
Have a nice day

Import dumpfile with seperate tablespaces for table and index

Hi,
We have a schema for which the its tables are stored in seperate tablespace and indexes are stored in different tablespace. Now we have take full schema export. Now we want to import it on another schema. Now I want to know if the we have difference in the tablespace name we use REMAP_TABLESPACE clause of the impdp command but what about the seperate tablespace for table and indexes. How would Oracle handle this.
Regards,
Abbasi

Hi,
I hope you created the same tablespace structure on the target side if not so remap_tablespace option you have to use for specifying different tablespaces.Oracle will take care of putting data and index.Any how if a index is moved from one tablespace to other you have to rebuild them,once you rebuild them than only stattistics are gathered otherwise you
might face some performance issue.
Better option is to keep same tablespace structures in source and target environment.

I tried with various hints, but Oracle is always doing a full scan on one of the tables and index FFS on other. In some cases, Oracle did full scan on both tables and then deleted 50 records. Stats is up-to-date. Doing a full scan on tables with 80 million and 47 million rows is a bit too much for deleting 50 rows.
How I can make Oracle do
1) Read TABLEA row-by-row
2) for each row, check if it exists in TABLEB
3) If not exists, then delete row from TABLEA, else continue
4) Stop reading TABLEA after we have deleted 50 records

---------------------------------------------------------------------------------------------------------Requirement is, I want to delete first 50 records in TABLEA, which does not exist in TABLEB.

How I can make Oracle do
1) Read TABLEA row-by-row
2) for each row, check if it exists in TABLEB
3) If not exists, then delete row from TABLEA, else continue
4) Stop reading TABLEA after we have deleted 50 records
It look's as if a 'no_unnest' hint in the subquery should do what you want. It should make Oracle run the quey with a FILTER subquery. You could then choose to drive the delete through a tablescan of tableA or an index range scan of the index on tableA. Have you considered the effect of (and requirements relating to) nulls in the three columns of either table ?

Heap tables and index organized tables

I performing migration from mssql server to oracle 10gr2 rdbms, in mssql all tables have clustered pk, index. Is it necessary to use index organized tables for that migration, or enough ordinal heap organized tables and what differences between those tables, and mssql tables
Thanx

In Oracle, the typical table is a standard 'heap' table. Stuff goes into the heap table randomly, and randomly comes out.
An Index Organizaed Tables is somewhat similar to a Cluster Index in SS. It can have some performance advantages over heap tables - when the heap table has an associated index on the primary key.
The IOT can also have some disadvantages, such as the need for an Overflow table to handle the extra data when a row doesn't conveniently fit in a block (implying multiple I/Os), and an extra translation table if bitmap indexes are required (implying extra I/Os).
An unintelligent developer will generally believe that Oracle and SQL Server are the same - after all they both run SQL - and will attempt to port by a simple translation of syntax.
An intelligent developer will test both styles of tables, during a port. Such a developer will also be quick to learn about the changes in internals (such as locking mechanisms) and will realize that different styles of coding are required for many application situations.
I recommend reading Tom Kyte's books to get handle on pros and cons as well as testing techniques to help a developer become intelligent.

BW DB13 Tables and indexes missing

hi, everyone,
our team find a strangethings in DB02 about the growth of table space, there is even no any growth, and it keeps about two months. and then we found that in tables and indexes all table about BW like *ODSD, *FACTD, *DIMD are missing!
I only find DB13C appear the error as" REOGR CHK for All Tables" at the same time .
please tell me why I can't find BW tables ? is there any relations between tables missing and job calendar?
our level is 701, and database is DB6.

It's a fool questions, i found the reason is so easy^^

Transaction DB02 = Missing Tables and Indexes shows under Secondary indexes from package $tmp

Hi SAP Gurus,
I noticed on our SAP business warehouse (BW) system (NetWeaver 7.0 based on AIX/Oracle 11g) in transaction DB02 => Diagnostics => Missing Tables and Indexes under Secondary indexes, 26 indexes, in package $tmp:
The indexes are defined, but they don't have been created on the database.
When I try to create them via the database tool, I am getting the warning:
Does the warning raise up, because they where defined in the $tmp package?
I was looking in SAP notes for a solution for this "warning" concerning the /BIC/F-Indexes but I didn't found yet anything helpful ...
Thanks for your help and ideas ...
Best regards
Carlos

Hi Carlos,
These are secondary indexes created during process chains in BI to improvise performance.
You may refer below SCN blogs on creation of these indices in BI.

Hope this helps.
