Selection Interface for large database

I am looking for a working example of a CF selection field that fills or builds a name list as you type. The database has about 600,000 names with 400 new people being added each day. I am looking for a smart tool that watches you type and brings down a name list as you go. In the list the user needs to see the name and other identifying information like DOB and phone number. User clicks the row and the persons recorded is located. I think I have a good understanding the CFC side of this.
If you type fast the tool waits for a second. "Sounds like" support would also be nice.
Thanks for any ideas?

You mean AutoSuggest? See this link:

You might want to adjust the code to work on official version because the example was built for beta version.

Modify selection screen for Logical Database 'SDF'

Hi
I need to make a section of the standard selection screen for logical database 'SDF' invisible. I have tried the differet selection screen options of the report attributes, but none of the provided ones give me what I want.
How can I find the name of the screen group for the "Line Item Selection" block of the selection screen so that I can make it invisible when the selection screen is displayed?
Thanks,
Thomas

I tried to do this:
Loop at screen.
         if   screen-group4 = '026'
           or screen-group4 = '027'
           or screen-group4 = '028'.
             screen-invisible = 1.
             modify screen.
         endif.
endloop.
This removed the selection text for these fields, but the Line Item Selection block is still visible, and the actual input fields are also visible. They now look like password input fields with all ***** in them.
What am I doing wrong?
Thanks for your help!

Hi Friends,
I'm actually starting administering a large Database 10.2.0.1.0 on Windows Server.

I'm good administering small and medium DBs, but some of them just got bigger and bigger!!!
Tks a lot

Sql Server Management Assistant (SSMA) Oracle okay for large database migrations?

All:
We don't have much experience with the SSMA (Oracle) tool and need some advice from those of you familiar with it. We must migrate an Oracle 11.2.0.3.0 database to SQL Server 2014. The Oracle database consists of approximately 25,000 tables and 30,000
views and related indices. The database is approximately 2.3 TB in size.
Is this do-able using the latest version of SSMA-Oracle? If so, how much horsepower would you throw at this to get it done?
Any other gotchas and advice appreciated.
Kindest Regards,
Bill
Bill Davidson

Hi
Bill,
SSMA supports migrating large database of Oracle. To migrate Oracle database to SQL Server 2014, you could use the latest version:
Microsoft SQL Server Migration Assistant v6.0 for Oracle. Before the migration, you should pay attention to the points below.
1.The account that is used to connect to the Oracle database must have at least CONNECT permissions. This enables SSMA to obtain metadata from schemas owned by the connecting user. To obtain metadata for objects in other schemas and then convert objects
in those schemas, the account must have the following permissions: CREATE ANY PROCEDURE, EXECUTE ANY PROCEDURE, SELECT ANY TABLE, SELECT ANY SEQUENCE, CREATE ANY TYPE, CREATE ANY TRIGGER, SELECT ANY DICTIONARY.
2.Metadata about the Oracle database is not automatically refreshed. The metadata in Oracle Metadata Explorer is a snapshot of the metadata when you first connected, or the last time that you manually refreshed metadata. You can manually update metadata
for all schemas, a single schema, or individual database objects. For more information about the process, please refer to the similar article:
https://msdn.microsoft.com/en-us/library/hh313203(v=sql.110).
3.The account that is used to connect to SQL Server requires different permissions depending on the actions that the account performs as the following:
• To convert Oracle objects to Transact-SQL syntax, to update metadata from SQL Server, or to save converted syntax to scripts, the account must have permission to log on to the instance of SQL Server.
• To load database objects into SQL Server, the account must be a member of the sysadmin server role. This is required to install CLR assemblies.
• To migrate data to SQL Server, the account must be a member of the sysadmin server role. This is required to run the SQL Server Agent data migration packages.
• To run the code that is generated by SSMA, the account must have Execute permissions for all user-defined functions in the ssma_oracle schema of the target database. These functions provide equivalent functionality of Oracle system functions, and
are used by converted objects.
• If the account that is used to connect to SQL Server is to perform all migration tasks, the account must be a member of the sysadmin server role.
For more information about the process, please refer to the similar article:
https://msdn.microsoft.com/en-us/library/hh313158(v=sql.110)
4.Metadata about SQL Server databases is not automatically updated. The metadata in SQL Server Metadata Explorer is a snapshot of the metadata when you first connected to SQL Server, or the last time that you manually updated metadata. You can manually update
metadata for all databases, or for any single database or database object.
5.If the engine being used is Server Side Data Migration Engine, then, before you can migrate data, you must install the SSMA for Oracle Extension Pack and the Oracle providers on the computer that is running SSMA. The SQL Server Agent service must also
be running. For more information about how to install the extension pack, see Installing Server Components (OracleToSQL). And when SQL Express edition is used as the target database, only client side data migration is allowed and server side data migration
is not supported. For more information about the process, please refer to the similar article:
https://msdn.microsoft.com/en-us/library/hh313202(v=sql.110)

Restrict Select-Options for Logical Database field

The way we restrict select options for custom defined select option fields on selection screen.. can we restrict select options for standard Logical Database fields?
i.e. report uses PNPCE logical database and has field called PERNR. I want to restrict select options for this PERNR field so that it has options for 'Select single values' only.
Thanks,
Falguni

You can user AT SELECTION-SCREEN event, and check whether any record is having high value for PNPPERNR.

SAP EHP Update for Large Database

Dear Experts,
We are planning for the SAP EHP7 update for our system. Please find the system details below
Source system: SAP ERP6.0
OS: AIX
DB: Oracle 11.2.0.3
Target System: SAP ERP6.0 EHP7
OS: AIX
DB: 11.2.0.3
RAM: 32 GB
The main concern over here is the DB size. It is approximately 3TB. I have already gone through forums and notes it is mentioned the DB size is not having any impact on the SAP EHP update using SUM. However am stil thinking it will have the impact in the downtime phase.
Please advise on this.
Regards,
Raja. G

Hi Raja,
The main concern over here is the DB size. It is approximately 3TB. I have already gone through forums and notes it is mentioned the DB size is not having any impact on the SAP EHP update using SUM. However am stil thinking it will have the impact in the downtime phase.
Although 3TB DB size may not have direct impact on the upgrade process, downtime of the system may vary with larger database size.
Points to consider
1) DB backup before entering into downtime phase
2) Number of Programs & Tables stored in the database. ICNV Table conversions and XPRA execution will be dependent on these parameters.
Hope this helps.

DR startegy for Large database

Hi All,
We have a 30TB database for which we need to design a backup strategy.( Oracle 11gR1 SE, 2 Node RAC with ASM)
Client needs a DR site for the database and from the DR site we will be running tape backup.
The main constraint we are facing here are size of DB which will grow till 50 TB in future and another is we are running in Oracle standard edition.
Taking a full RMAN backup to a SAN box will take around 1 week for us for a DB size of 30TB.
Options for us:
1. Create a manual standby and apply archive logs( We cant use Dataguard as we are in SE edition)
2. Storage level replication ( Using HP Continous access)
3. Use thrid party tools such as Shareplex,Golden gate, DBVisit etc
Which one will be the best option here with respect to cost and time or do we have any other option better than this.
We cant upgrade to Oracle EE edition as of now since we need to meet the project deadline for Client. We are migrating legacy data to production now and this will be interrupted if we go for a upgrade.
Thanks in advance.
Arun
Edited by: user12107367 on Feb 26, 2011 7:47 AM
Modified the heading from Backup to DR

Arun,
Yes this limitation about BCT is problematic in SE but after all if everything was included in SE who would pay the EE licence :) ?.
Only good thing if BCT is not in use is that RMAN checks the whole database for corruption even if the backup is an incremental one. There is no miraculous "full Oracle" solution if your backups are so slow but as you mentioned the manual standby with delayed periodic applications of the archives is possible. It's up to you to evaluate if if works in your case though : how many archive log files will you daily generate and how long will it take to apply them on your environment ?
(notice about Golden Gate it's no more a third party tool : it's now an Oracle tool and it is clearly introduced as a recommended replacement for Streams)
Best regards
Phil

User defined Selection screen for Logical database

hi all,
       can we display a user defined selection screen instead of the default selection screen in LDB . eg pnp
cheers
senthil

Hi,
to my knowledge, the selection screen of a logical database can only be changed (versions!) in the logical database itself.
What you can do is, write a program with your own selection screen an then either call another program that uses the LDB or - much better - you call the LDB from your program with function module LDB_PROCESS!
Example taken from the example library (TA ABAPDOCU):
<b>REPORT demo_logical_database.

BRTOOLS with tape continuation for large database

Hello,
I have a R/3 database of 2TB which needs to be copied onto a new staging server for upgrade.
The problem I am facing is that I dont have any space in the SAN(storage) for taking the backup on disk.
So the only option I have is to take backups on tape.
Even tried backup with compress mode on tape but ended up with CPIO error for handling larger than 2GB files(note 20577).
And Since the database size is 2TB and the tapes I have hold 800GB I would have to use multiple tapes.
Since my some of the files in the database like *DATA_1 range between 6GB to 10GB CPIO cannot
handle files larger than 2GB as per note 20577.
So I had to change the parameter tape_copy_cmd = dd in init<sid>.sap.
But DD will end once the end of tape is reached with a error message thereby failing my backup.
Please help me get out of this situation.
Regards,
Guru

Hi,
Please check the 'Sequential backup' section in the backup guide. If its not possible to use a tape with a big capacity, you could use this method instead.
You would need to add/ modify the following parameter in init<sid>.ora :
1. volume_backup
2. tape_address
3.tape_address_rew
4.exec_parallel
You'll find more info about these parameters in www.help.sap.com and in the backup guide itself.

Changing selection sequence for logical database

Hi,
One of my current report is using logical database PNP. The users are satisfy with the standard selection screen. However they would like me to change the sequence of the selection field. Example, current sequence is Personnel number, company code, employee subarea. They would like it be Personnel number, employee subarea, company code.
Is there any way I can change the sequence of the selection screen? I tried using report catagory but it don't allow me to change the sequence. Please advise.
Regards,
Lanwu

Rich is correct.. but there is a workaround..
Use the Report Category that suppresses all the selection fields.. I the program deifne your selection screen with the fields in your own order preference. In the STARt-OF-SELECTION event.. pass the values entered to the PNP fileds.. ie suppoes you have declared S_PERNR ( for Pers No), then use PNPPERNR[] = s_pernr[]. This way you will not have to change the LDB program..

Oracle for large database + configuration

Hi
I have some historical data for Stocks and Options that I want to save into an Oracle database. Currently I have about 190G of data and expect to grow about 5G per month. I have not completely thought about how to organize the tables. It is possible that there might just be one table which might be larger than the hard disk I have.
I am planning to put this on a DELL box, running Windows 2000. Here is the configuration.
Intel Xeon 2.4GHz, 2G SDRAM, with 3 146G SCSI harddrive with PERC3 SCSI controller. This machine roughly costs 7000$.
Is there any reason that this wont work. Will Oracle be able to organize one database across multiple disks? How about Tables? Can Tables span multiple disks.
All this data is going to be read only.
My other cheaper choice is
Intel box running P3, 2G RAM, 2 200G IDE drives. My questions for this are/ Will this configuration work?
Also, for this kind of a database what kind of total disk space should I budget for?
thanks
Venkat

Backups for large databases

I am wondering how people do restores of very large DB's. Ours is not that large yet bit will grow to the point where exports and imports are not feasible. The data only changes periodically and as it is a web application,cold backups are not really an option. We don't run in archived log mode because of the static nature of the data. Any suggestions?

put the read only tables in a read only tablespace and slowly changing tables to another tablespace. the most frequent ones in another tablespace.
take transportable tablespace export of the frequently changing tablespace daily and slowly changing 2-3 times a week (depending on your site specifics). this involves nothing but a metadata export of the datadictionary info of the tablespaces exported and an OS level copy of the datafiles of those tablespaces.
this is the best way for you to backup/recover. check out oracle documentation or this website for transportable tablespaces.
I guess it comes to a point where you have to make a tradeoff between performance and recoverability. In my opinion always take recoverability over performance.
If the periodic change of data is nothing but a bulk data load then after the dataload take a backup of a database. having multiple recovery scenarios is the best way for recovery.

Selection screen for logical database PNP..

hi all,
I am having a requirement to produce a HR Report where i need to use logical database PNP. Now the issue is i need to supress some of the elements of standard selection screen of PNP and add a couple of fields of mine.
i have been looking all around and i got few of the below methods.
its good to use a report category.
somewhere it says include it in ur program using selection screen block..
can you please guide me which is the best way and what would be a perfect solution?
thanks in advance,
Reena

Hi reeena,
1. simple
2. u want to
a) add ur own fields
b) suppress some fields
3. a) is simple, just add your parameters,
   in your program, and they will appear
   b) use SCREEN logic
4. just copy paste to get a taste of it
(it will HIDE the PAYROLL AREA field)
and add MATNR field
5.
report abc.
TABLES : PERNR.
PARAMETERS : MATNR LIKE MARA-MATNR.
AT SELECTION-SCREEN OUTPUT.
LOOP AT SCREEN.
    IF SCREEN-NAME CS 'ABKRS'.
      SCREEN-INVISIBLE = '1'.
      SCREEN-INPUT = '0'.
      MODIFY SCREEN.
    ENDIF.
ENDLOOP.

Remove fragmentation for large database

I have two databases each with page file size close to 80GB, Index 4GB. Average Clustering Ratio on
them is close 0.50. I am in a dillema how to defragment these databases. I have two options -
1> Export level0 data, clear all data (using Reset), Reimport level0 data and fired a calc all.
2> Export all data. clear all data (using Reset), Reimport all data.
Here is the situation.
-> Export all data is running for 19 hours. Hence I could not continue with option 2.
-> Option 1 works fine, but when I fire the calc after loading level0 data, Average clustering ratio
goes back to 0.50. So the database is fragmented again. I am back to the point where I had started.
How do you guys suggest to handle this situation?
This is version Essabse 7. ( yeah, it is old).

The below old thread seems to be worth reading:
