Maxdb and datafiles
Hello Everyone,
I am facing a problem in file system designing for ECC 6.0 System. We are working with MAXDB on linux redhat platform.We have created a file system "/sapdb/sid/sapdata1" for datafile. We got info from the Linux admininstrator that this file system cannot be extended to higher size in future.
So if I come across a situation that the file system "/sapdb/sid/sapdata1" is full then can I create a new file system "/sapdb/sid/sapdata2" and use it for new datafiles of maxdb as we do in oracle . Is this work or I should give more space to "/sapdb/sid/sapdata1", Currently the size given is 80 GB. We are having problem with the space availability of local harddisk.In future we will get NAS or SAN so we can use that for creating new file system "/sapdb/sid/sapdata2"
Please help us in this regard
Thanks
Hany
Hello All,
We are using MaxDB for our content management system. We have MaxDB data volumn of size 200MB each.
We can add more data volumn but not able to increase the size of data volumn (we want to create a data volumn of size 1GB each).
Can you please advise how can we increase the size of data volumn?
Thanks in advance and best regards.

MaxDB and LiveCache installation
Hello All,
Tying to install LiveCache 7.7 part SCM 5.1 = SCM 2007
I am trying to install liveCache on SuSE 10(Linux) with MaxDB. I would like to know that if I need to install MaxDB before I install the Livecache server using sapinst? Please advice!
I thought sapinst should ask for MaxDB file during the sapinst process? I started the with sapinst without installing MaxDB and now I am on the steps (Intance parameters) --> I checked Volume Medium type as Raw Devices --> Clicked on Next, I entered /sapdb as raw devices according to SAP Inst manual I click on NEXT and I got this error message: Selected item is not a valid Raw Device: /sapdb. SOLUTION: Select a valid raw device?
Please someone tell me what is exactly valid RAW Device?
Thanks in Advance
KumarHello Kumar,
-> Please run /nLC10 -> set LCA -> click on Integration
=> You will get the screen where you could see the User Data settings.
You have to set the DBM user & Standard liveCache user <LCUSER> with the passwords
correctly. To run the liveCache application you have to connect first from the application
as the LCUSER.
-> Please logon to the liveCache server as user in the 'sdba' group & run :
dbmcli -d <LC-name> -u control,<pwd>
<enter>
dbmcli on <LC-name>>db_state
< if the liveCache is offline =>next step, skip it if it's already 'online' >
dbmcli on <LC-name>>db_online
dbmcli on <LC-name>>sql_connect superdba,admin
dbmcli on <LC-name>>sql_execute select * from users
dbmcli on <LC-name>>sql_release
dbmcli on <LC-name>>exit
-> Please follow up the liveCache installation guide. If the liveCache was installed, there are also post installation steps.
-> For SAP liveCache documentation in English < See the SAP note 767598 >:

Taking rollback segment and datafile offline caused application error
One of the DBA's added a large rollback segment which caused the rman backup to abort. The rollback segment was taking offline and it's datafile was taken offline, all went normally no errors. An Application started gettting errors the database and application were taking down and up, no errors on either but the problem was still there. The rbs datafile and RBS were placed back online and the application worked properly. It looks as if Oracle let us take the RBS and datafile offline with active segments in the RBS is this possible?? If so it means you can pull the rug out from under Oracle and it doesn't even complain
Pls check any transactions written in application level,
explicitly assigned to the RBs which was taken offline. -
Tablespace and Datafiles... HELP

nullHi Ruben,
I'm an Ora admin working under NT.
Use oracle server manager to create datafiles & tablespaces.
You can find the executable file name for oracle server manager
(svrmgr??.exe for NT) under BIN irectory of ORACLE HOME.
Hope this will be tip for you.

I have 3 test databases with Oracle 11.2.3 on the same box
data.dbf and index.dbf were deleted from 2 of the databases in SQL and now EP Manager can't get to any of the tablespaces. when clicking on Server - Tablespace i get the following error:
java.sql.SQLException: ORA-01116: error in opening database file 2 ORA-01110: data file 2: '/u02/oradata/LAWTEST/dev_data01.dbf' ORA-27041: unable to open file IBM AIX RISC System/6000 Error: 2: No such file or directory Additional information: 3 Additional information: 4 Additional information: 4194304
I have tried dropping the tablespaces and refreshing the database from a Prod backup but no luck and have been searching the web for any info.
Any help would be greatly appreciated.Hi,
I would like to ask where is stored in the database
the information regarding the tablespace and
datafiles (for example for a tablespace which
datafiles belong?). Is it in controlfile? I think no.
Where is it?
Thank you,
MihaelaHi,
You may query DBA_TABLESPACES or V$TABLESPACE to views to gain information on tablespaces. Similarly, DBA_DATA_FILES and V$DATAFILE views will list you the details related to the data files like tablespace name/id, file location ......etc..

Difference Between Cofiles and Datafiles
Hi
Can Any one pls explain the Difference Between Cofiles and Datafiles in Trans Directory.
Need to know their Role and Internal Process in Transporting the Request or a Client.
Thanks in Advance
DanHi,
Data file contains actual change data.
Cofile contains information on change requests (different steps of a change request and their exit codes).
So you will find cofile of same size for all requests.
Regards

SQL> ALTER TABLESPACE CNT_TST ADD DATAFILE '/data3/trgt/CNT_TST02.dbf' SIZE 100M AUTOEXTEND OFF;
Tablespace altered.
SQL> ALTER SYSTEM CHECKPOINT;
System altered. Upto this i was clear, but now i cann't understand when you actually dropped the control file from you database(in running stat) how can you perform "alter system checkpoint" and other "alter tablespace.." command? Once controlfile is inaccessible, oracle database is not suppose to function. -
Database migration to MAXDB and Performance problem during R3load import
Hi All Experts,
We want to migrate our SAP landscape from oracle to MAXDB(SAPDB). we have exported database of size 1.2 TB by using package and table level splitting method in 16 hrs.
Now I am importing into MAXDB. But the import is running very slow (more than 72 hrs).
Details of import process as per below.
We have been using distribution monitor to import in to target system with maxdb database 7.7 release. We are using three parallel application servers to import and with distributed R3load processes on each application servers with 8 CPU.
Database System is configured with 8CPU(single core) and 32 GB physical RAM. MAXDB Cache size for DB instance is allocated with 24GB. As per SAP recommendation We are running R3load process with parallel 16 CPU processes. Still import is going too slow with more that 72 hrs. (Not acceptable).
We have split 12 big tables in to small units using table splitting , also we have split packages in small to run in parallel. We maintained load order in descending order of table and package size. still we are not able to improve import performance.
MAXDB parameters are set as per below.
CACHE_SIZE 3407872
MAXUSERTASKS 60
MAXCPU 8
MAXLOCKS 300000
CAT_CACHE_SUPPLY 262144
MaxTempFilesPerIndexCreation 131072
We are using all required SAP kernel utilities with recent release during this process. i.e. R3load ,etc
So Now I request all SAP as well as MAXDB experts to suggest all possible inputs to improve the R3load import performance on MAXDB database.
Every input will be highly appreciated.
Please let me know if I need to provide more details about import.
Regards
SantoshHello,
description of parameter:
MaxTempFilesPerIndexCreation(from version 7.7.0.3)
Number of temporary result files in the case of parallel indexing
The database system indexes large tables using multiple server tasks. These server tasks write their results to temporary files. When the number of these files reaches the value of this parameter, the database system has to merge the files before it can generate the actual index. This results in a decline in performance.
as for max value, I wouldn't exceed the max valuem for 26G value 131072 should be sufficient. I used same value for 36G CACHE SIZE
On the other side, do you know which task is time consuming? is it table import? index creation?
maybe you can run migtime on import directory to find out

NOARCHIVE mode and datafile DROP OFFLINE
I have a 10gR2 database on linux that I use for testing. The db is in NOARCHIVE mode.
I had created test tablespaces on a NAS (as opposed to the system tables on the local machine). The NAS crashed, losing the drive mapping on the db machine. Of course, I couldn't start the database due to the missing datafiles. I did an 'alter database datafile 'xxxx' drop offline', which put the datafiles in RECOVERY mode in the datafiles view.
Amazingly, I was able to recover the NAS several days later, and the datafiles.
Is there any way to restore them after a drop offline? When I try to online them, I get recovery needed, when I try to recover, none of the redo logs have the right checkpoint. (The checkpoint needed is less than what are in the redo logs)
I don't care about any data that might have been lost. The data was static for months.
Any suggestions?
Edited by: user10822921 on Nov 4, 2009 5:03 AMIf the database is asking for recovery when you online the files, and you don't have those transactions in the redo logs, you can't recover to a consistent point in time to online the files.
# Note that the following is not supported by Oracle Support. You may want to ask them for a second opionion.
You could try taking a copy of all files to another location, recreate the controlfile, and use parameter "_allow_resetlogs_corruption=TRUE" to allow "open resetlogs" to ignore the inconsistent SCN. If it works, you should be able to export the data in the copy database, drop the objects in PROD, and re-import. -
SAP MaxDB and EclipseLink/JPA?
Folks;
is anyone out here using MaxDB along with EclipseLink JPA 2.0 implementation, especially as far as it concerns automatic table creation using predefined @Entity classes? So far, I mainly happened to see a whole load of different error messages but yet haven't found a way of getting things to work cleanly, like, at the moment:
Call: ALTER TABLE S_CFG_SS_CFG_ATTS ADD CONSTRAINT FK_S_CFG_SS_CFG_ATTS_atts_ID FOREIGN KEY (atts_ID) REFERENCES SS_CFG_ATTS (ID)
Query: DataModifyQuery(sql="ALTER TABLE S_CFG_SS_CFG_ATTS ADD CONSTRAINT FK_S_CFG_SS_CFG_ATTS_atts_ID FOREIGN KEY (atts_ID) REFERENCES SS_CFG_ATTS (ID)")
[EL Warning]: 2009-11-24 12:25:30.376--ServerSession(30633470)--Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.0.0.v20091031-r5713): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: com.sap.dbtech.jdbc.exceptions.DatabaseException: [-5016] (at 71): Missing delimiter: )
Error Code: -5016
Does anyone around here know how (if so) to get EclipseLink to behave well teaming with MaxDB?
TIA and all the best,
KristianPlease check for the official EclipseLink MaxDB support. You might want to post this question to the Eclipse forum.

I would like to install SAP Netweaver 2004S SR2 Developer Workplace on my windows XP desktop. I am using the official DVD containing the Developer Workplace, but the installation requires the maxDB. Where can I get a copy of maxDB suitable for my installation? On the internet I found many places from which I can download a copy of maxDB, but which one is the right one?
Thanks in advance.It´s on the DVD - no need to separately install something, the installer will automatically install and configure the database.

Hi,
I would like to know if the community releases of MaxDB can run in a VMware Windows guest.
I had access to SAP Note 1142243 that mention that this is the case as of version 7.6.04.07.
I don't quite understand the hierarchy of MaxDB releases, but I read somewhere that the third number is more like a feature number than a release order.
So what about 7.6.3.x and 7.6.5.x ?
Thanks,
GuillaumeHi Guillaume,
basically you may run also a 7.6.3.x MaxDB in a VM host.
I did that e.g. with Parallels on Mac OS X as host with Windows XP and Fedora 8 as guest os and had no issues.
Anyhow, the official supported versions have to be 7.6.4.x or higher - so 7.6.5.x from the SDN Download will be perfectly supported with VM scenarios.
Concerning the version string, this is the explanation from note "820824 - FAQ: MaxDB / SAP liveCache technology"
4. How can I interpret the MaxDB version string?
Importance for Version 7.5 or lower, for example kernel version 7.5:
7.5.0 BUILD 026-123-094-430
Major Number: 7
Minor Number: 5
Correction Level: 0
Build Number: 026
Support Information: 123-094-430
The interpretation of the MaxDB/liveCache version string changes with MaxDB Version 7.6.
Importance for Version 7.6 or higher, for example kernel version 7.6:
7.6.01 BUILD 020-123-115-206
Major Number: 7
Minor Number: 6
Support Package: 01.
Patch Level:020 (Build Number)
Support Information: 123-115-206
As of Version 7.6, a model was introduced with Support Packages and patch levels.
Support Packages:
- are created on a quarterly basis (approximately)
- in addition to the error corrections, Support Packages also include new functions (change requests).
Patch levels:
- are created more often than Support Packages and according to requirements (error situation),
- only high priority errors are corrected,
- corrections for delivered versions always result in a new patch level number.
Best regards,
Lars -
I need to start a heterogeneous copy using R3load (Linux --> HP-UX IA64) of a 2,6 TB MaxDB 7.7 and checked beforehand some notes and found the above note stating
The general R3ta support for MaxDB will be available for SAP Systems
with MaxDB 7.8 and above. At the moment there is only limited MaxDB
R3ta support available.
The source systems contains tables with up to 110,000,000 rows so it's just impossible to copy them sequentially, that would take WEEKS.
What kind of "limitation" is implied and is there no chance to get R3ta to work? This would kill our current project.
MarkusHey Roland,
> just FYI: I'm checking your question with the creator of the mentioned note. I'll get back to you.
Thank you!
We had - quite some time ago - a call about R3ta and the slowness of it during calculation times (OSS 1039828 / 2008 ), maybe that is somehow related.

SAP Newbie - MaxDB and NetWeaver limitations
We are new SAP partner (SR) licensing mySAP Business Suite on MaxDB/Windows platform. What are limitations regarding further NetWeaver configurations (ordering). I saw on Product Availability Matrix that only MaxDB/Linux configurations are available for EP. Does that mean that we will not be available to license EP?
Thanks in advance,
IgorHi Igor,
The Product Availability Matrix doucment is the most up to date information on the availability for SAP NetWeaver components. It will be supported with SAP NetWeaver '04 SR1 which should be available later in the year.
If you can't wait, I would suggest that you contact your partner contact at SAP and discuss getting either the Linux version or a supported windows/DB combination like SQL Server.
I hope this helps,
Mike. -
Database Performance (Tablespaces and Datafiles)
Hi guys!
What's the best for performance in database, tablespace with various datafiles distribuited in diferents filesystems or tablespaces with various datafiles in only one filesystem?
Thanks,
AugustoIt depends on contents of the tablespaces, tablespace level LOGGING/NOLOGGING and env such as either OLTP or OLAP and LUN presentation to the server with RAID or without RAID and SAN Read per second and write per second.
In general, tablespace with various datafiles distribuited in diferents filesystems/LUN's is in practice for non dev/system test databases.
Moreover using ASM is better then standard filesystems.

Kamalesh
