DB2 SAP

Hello Gurus - I am a newbie when it comes to DB2 on SAP (although I am a seasoned DB2 DBA) on Unix and Windows. First of all, I am glad that I have joined this forum as I can learn and hopefully share my DB2 knowledge with you folks. Now getting to my question.. What might be few articles that you would suggest for a DBA like me who is excited about DB6 but just lost ?? I hear lots of terms like DBA **** pit, SAP CCMS etc etc. Can you throw some light along these lines?
I highly appreciate your input and/or any articles that you can lead me to.
Best.
PavanK.

Hello Pavank,
there's a nice and free guide to DB2 Express-C which has the same base functionality and architecture as DB2 Enterprise Server. You can get it here: Free DB2 book.
Optionally you can use the great repository of DB2-Resources of the DB2 user community or the official DB2 online documentation
In order to build the bridge to SAP, I would recommend - as Hans-Jürgen already mentioned - the DB6 Admin Guide.
These guides should provide a good introduce in both, the DB2 and the DB6 (DB2 LUW for SAP) World. I hope this will be helpful for you.
Best regards,
Marcel

Hi Jin-Chong
many thanks for you help. But the problem still persists.
1. We don't have $ODBCINI. There are no conection issues at all. Connection is performed by IBM Data Server Client (db2client) db2 connect to ...
2. For which stored procedures do we need to apply these Grants? We manually exported the available historical data from the TrendingDB to CSV files, connected to the database server with db2 connect... (on the app server), imported these CSV with the same user, it all went smoothly. We granted some DML's to the database user. also granted DBADM and SECADM to the database user as well, just to be sure there are no permission issues.
The Error message seems to indicate There is a problem finding the correct driver for monitoring database, since it says,
      networkLayer    "ODBC"
        DBMS    "DB2"
com.sap.connectivity.cs.core.CSError: Specified RDBMS is invalid : DB2.
- Maby IBM Data Server Client (db2client) is not supported for monitoring database at all?
- Do we have to install additional DB2 clients like DB2 CLI driver or ODBC client instead?
Thanks in advance

DB2 v9.1fp4 on suse linux 10sp2 - redirect restor PRD to DEV

Hi All,
First of all thank you, for valuable TIME.
issue:
My development server got crashed due to failure of dedicated SAN. in simple lost every thing. since, even DB2 backups happening to SAN.
requirement:
As we lost all the developments and configuration of development server, we need build a DEV from PRD.
Steps taken:
a. we have installed Suse 10sp2 followed by db2 v9.1 fp4 and SAP ERP6.0 sr2.
b. taken backup of db2 & sap kernel backup by tar command followed by SAP db13 backup along with logs - for newly installed Development server.
hostname - development
SID - DEV
c. I need to restore development server with sid DEV from the backup of production with sid PRD.
 To get all the data {development data, transaction data & configuration etc..}
Problem
Till now i haven't worked on DB2 restore, and the current requirement is to dump data from PRD in to DEV.
i.e.. db2 redirect restore
current landscape status:
Both production and development {freshly installed} are up and working fine.
PRD with all the live data, DEV freshly installed and without data.
Need to restore data from PRD to DEV.
Database: DB2 v9.1 fp4
OS: SUSE linux 10 sp2
SAP solution: ERP 6.0 sr2
Backup of PRD: in to SAN box {backup folder}, backup triggered by DB13 with include logs option.
I request you to guide me in understanding and performing the restoration.
i.e.. the steps to be performed along with the necessary precautions to be take to avoid problems.
PRD data to DEV.
Thank you very much your time.

Hi,
Did you configure a connection timeout or a receive timeout?
This can be done by the following settings in db2cli.ini ( /usr/sap/SAPSID/SYS/global/db6/db2cli.ini for CLI driver setup ).
ConnectTimeout = #value#
or
ReceiveTimeout = #value#
Also check the DB2 registry for attributes like DB2TCP_CLIENT_RCVTIMEOUT or DB2TCP_CLIENT_CONTIMEOUT .
All those parameters are non standard for an SAP DB2 installation.

Db2 backup on aix

Hi,
We are running SAP on AIX 5.3 AND db2 udb 8.2.3. We have taken full offline backup from OS level. e.g. /usr, /sapmnt, /usr/sap/trans, /home, /db2/<SID>, /db2/log_dir etc. May i restore the backup on another server without installing DB2 software? and run the SAP? or do we need to re-install DB2 & SAP again and then restore the database backup?
Please guide.
-SN

Hi Jennifer,
it is much easier and less error prone to do a system copy with the build in DB2 backup and restore commands. Copying DB2 by copying files from one server to the other should only be done by experienced DB2 administrators and in most cases there is no need to do this. For example using the wrong OS tools may create sparse allocated DB2 container files and can create unexpected error situations.
The DB2 V8 software installer on AIX uses the OS installer. The DB2 V8 software is installed under /opt and the /db2/db2<sid>/sqllib directory contains links to this directory. Therefore it is not enough to copy the /usr/sap ; /sapmnt and /db2 directories. With DB2 V8 the software installtion directory is fixed. With DB2 V9+ the software can be installed in any directory and as a default new SAPINST versions install the DB2 software under /db2/db2<sid> .
To do a cold copy of DB2 you may also need to use the db2inidb and db2relocated tools ( mostly used for split mirror copies ), especially if you want to rename your dbsid. You can find more information about those tools in the DB2 docu. The SAP utility brdb6brt ( note 867914 ) may also provide some help.

Frank

DB2 backup alternatives

Hi Friends,
I´am very new in DB2. I would like to know some alternatives for the DB2 database backup.
Could be an option to make an offline backup of all the file systems related to db2 in order to restore consistently?
What could be the impact?
We can assume that DB2 is down.
Thanks in advance
Enrique Sánchez

Hi,
As like other database, you should take offline, online and archive log backup regularly to maintain the consistency of your landscape. Offline backup depends upon whether system is production, quality etc. as during offline backup system will not be available so you can plan for every month or every 15 days..depends upon your business requirement.
Online backup and archive log backup should be scheduled daily.
E.g: if you have taken offline backup one month back and after that system crashed then you should restore with online backup and apply archive logs for point in time recovery.
Please check following book for backup on DB2:
[Db2 Admin Guide|http://maben.homeip.net/static/computers/sap/DB2/SAP%20on%20IBM%20DB2%20Universal%20database%20for%20UNIX%20and%20Windows%20Admin%20NW04.pdf]

Check the connect to DB & SAP

Hello Guys,
Like R3trans -d for Oracle & SAP.. I wanted to know how to check the connection test for DB2 & sap , Is there any such commend Please let me Know,
Thanks,

Hi,
if u want to connect from R3 to any other SAp system like XI/PI,MDM,etc...
u can create a RFC destination in R3 (SM59) and give d IP and credentials in the columns specified.
After that click on Test connection tab which shows the details of connection like time required.
You can even click on Remote Logon to directly log in to the destination system...
Thus u can check d connection
Reward points if helpful

Hello Gaurav.
You are able to implement SAP BI using BCU configurations. There is not yet a SAP-specific BCU, though, so with existing BCU configurations, you must ensure that the administration node (partition 0) has enough capacity for the extra load from system catalogs, basis tables, all SAP application server connections, etc. With a standard BCU implementation, all machines are identical, so you must plan your BI layout and BCU configuration accordingly.
Whirlpool (a large North American home appliance company) very successfully implemented their DB2 SAP BW data warehouse on BCU systems, so you certainly can make it work.
Best regards,
Jer

Report painter performance problem...

I have a client which runs a report group consists of 14 reports... When we run this program... It takes about 20 minutes to get results... I was assigned to optimize this report...
This is what I've done so far
(this is a SAP generated program)...
1. I've checked the tables that the program are using... (a customized table with more than 20,000 entries and many others)
2. I've created secondary indexes to the main customized table with (20,000) entries - It improves the performance a bit(results about 18 minutes)...
3. I divided the report group by 4... 3 reports each report group... It greatly improves the performance... (but this is not what the client wants)...
4. I've read an article about report group performance that it is a bug.
(sap support recognized the fact that we are dealing with a bug in the sap standard functionality)
http://it.toolbox.com/blogs/sap-on-db2/sap-report-painter-performance-problem-26000
Anyone have the same problem as mine?

Report painter/Writer always creates a prerformance issue.i never preffred them since i have a option with Zreport
now you can do only one thing put more checks on selection-screen for filtering the data.i think thats the only way.

Best Practices for zVM/SLES10/zDB2 environment for dialog instances.

Hi, I am a zSeries system programmer who has just completed an IBM led Proof of Concept which demonstrated the viability of running SAP instances on SUSE SLES10 Linux booted in zVM guests and accessing zDB2 data via hipersockets. Before we build a Linux infrastructure using the 62 IFLs we just procured, we are wondering if any best practices for this environment have been developed as an OSS note or something else by SAP.    Below you will find an email which was sent and responded to by IBM and Novell on these topics...
"As you may know, Home Depot has embarked on an IBM led proof of concept using SUSE SLES10 running in zVM guests on IBM zSeries hardware to host SAP server instances. The Home Depot IT organization is currently in the midst of a large scale push to modernize our merchandising and people systems on SAP platforms. The zVM/SUSE/SAP POC is part of that effort, as is a parallel POC of an Intel Blade/Red Hat/SAP platform. For our production financial systems we now use a pSeries/AIX/SAP platform.
      So far in the zVM/SUSE/SAP POC, we have been able to create four zVM LPARS on IBM z9 hardware, create twelve zVM guests on those LPARS, boot SLES10 in those guests, install and run SAP instances in those guests using hipersockets for access to our DB2 SAP databases running on zOS, and direct user workloads to the SAP instances with good results. We have also successfully developed cloning scripts that have made it possible to create new SLES10 instances, configured and ready for SAP installs, in about 10 seconds using FLASHCOPY and IBM DASD.
      I am writing in the hope that you can direct us to technical resources at IBM/Novell/SAP who may be able to field a few questions that have arisen. In our discussions about optimization of the zVM/SUSE/SAP platform, we wondered if any wisdom about the appropriateness of and support for using zVM capabilities to virtualize SAP has ever been developed or any best practices drafted. Attached you will find an IBM Redbook and a PowerPoint presentation which describes the use of the zVM discontiguous shared segments and the zVM named saved system features for the sharing of reentrant code and other elements of Linux and its applications, thereby conserving storage and disk resources allocated to guest machines.   The specific question of the hour is, can any SAP code be handled similarly? Have specific SAP elements eligible for this treatment been identified?
      I've searched the SUSE Knowledgebase for articles on this topic to no avail. Any similar techniques that might help us reduce the total cost of ownership of a zVM/SUSE/SAP platform as we compare it to Intel Blade/Red Hat/SAP and pSeries/AIX/SAP platforms are of great interest as we approach the end of our POC. Can you help?
      Greg McKelvey is a Client I/T Architect at IBM. He found the attached IBM documents and could give a fuller account of our POC. Pat Downs, IBM zSeries IT Architect, has also worked to guide our POC. Akshay Rao, IBM Systems IT Specialist - Linux | Virtualization | SOA, is acting as project manager for the POC. Jim Hawkins is the Home Depot Architect directing the POC. I've CC:ed their email addresses. I am sure they would be pleased to hear from you if there are the likely questions about what the heck I am asking about here. And while writing, I thought of yet another question that I hoping somebody at SAP might weigh in on; are there any performance or operational benefits to using Linux LVM to apportion disk to filesystems vs. using zVM to create appropriately sized minidisks for filesystems without LVM getting involved?"
As you can see, implementation questions need to be resolved. We have heard from Novell that the SLES10 Kernel and other SUSE artifacts can reside in memory and be shared by multiple operating system images. Does SAP support this configuration? Also, has SAP identified SAP components which are eligible for similar treatment? We would like to make sure that any decisions we make about the SAP platforms we are building will be supportable. Any help you can provide will be greatly appreciated. I will supply the documents referenced above if they are not known to any answerer. Thanks, Al Brasher 770-433-8211 x11895 [email protected]

Hello AL ,
first, let me welcome you on board, I am sure you won't be disapointed with your choice to run SAP on ZOS.
as for your questions,
it wan't easy to find them in this long post , so i suggest you take the time to write a short summary that contains a very short list of questions.
as for answers.
here are a few usefull sources of information :
1. the sap on db2 for Z/os sdn page :
SAP on DB2 for z/OS
in it you can find 2 relevant docs :
a. best practices for ...
b. database administration for db2 udb for z/os .
this second publication is excellent , apart from db2 specific info , it contains information on all the components of the sap on db2 for z/os like zlinux,z/vm and so on ...
2. I can see that you are already familiar with the ibm redbooks , but it seems that you haven't taken the time to get the most out of that resource.
from you post it is clear that you have found one usefull publication , but I know there are several.
3. a few months ago I wrote a short post on a similar subject ,
I'm sure its not exactly what you are looking for at this moment , but its a good start , and with some patience you may be able to get some answers.
here's a link
http://blogs.ittoolbox.com/sap/db2/archives/index-of-free-documentation-on-sap-db2-administration-14245
good luck.
