SAP Binaries Backup online or offline

Hello!
I woulld like to know, how to execute the regular SAP OS backup and have the following questions regarding this issue:
1) How often should I backup the SAP-Binaries-partition \usr\sap\...?
(daily, weekly, 1 times month)
2) Should the DB, SAP R/3 or some Services be stopped for this issue?
Do exist some file-locks avoiding offline backup of \usr\sap\... ?
3) What should be backuped from \usr\sap\...?
(trans, profiles)
Thank you very much!
regards
Thom

Hi Thom,
1). It's totally depend's on your system avilability(because you need to make the system offline), rest may be you can take OS level backup once in a month(standard practice with all the data centers).
2). Yes you better stop DB services and SAPOSCOL.
3). You can backup total dir structure and you better create one Emergency Repair Disk(ERD) in case of windows.

Hari.

Low Network Utilization in Remote Disk Backup via SAP FTP

Hi gurus,
I'm running whole online backup + redo log to backup my SAP server to backup server via SAPFTP (remote disk backup).
I'm using 100Mbps network connection between the two servers, with SAP server configured to 'maximize data throughput for network application'.
When I copy data from SAP Server to backup server manually, the speed is OK (around 98% network utilization).
But when I use put command in program RSFTP002 (SAPFTP) for the same file, the network utilization is just around 10%.
I use Windows Server 2003 x64 for SAP Server, and Windows Server 2008 x64 for Backup Server.
Each has adequate RAM, 8GB for SAP Server and 4GB for Backup Server.
Is this technical problem or is it because backup is considered background process, thus lowering its speed?
Help will be very much appreciated.

go read http://help.sap.com/saphelp_45b/helpdata/en/0d/d311324a0c11d182b80000e829fbfe/frameset.htm
it's old but should help you nonetheless.
I would not use SAPFTP as you found out, it is slow.
use DD instead which is much faster.

Best option for testing the Restore of an Backup Online with Legato

In my company is needed to test of Restore of an Backup Online with Legato of my Production System in a server available for test with the same operating system Windows 2000 Server, the same version of SAP R/3 4.6B and database Oracle 8.1.7.4.1, but the SID is different.
My question as is the best way to make this procedure? It will need to return to install sap with the same SID of production ??? or a way exists to change the SID and next to restore the backup online.
I like to know me the best one practice that they can recommend to me for these cases.
Thanks to all

Hi,
/people/sap.user72/blog/2006/03/04/complete-xi-backup-restore-in-an-hour How u feel abt this.
The R3COPY (for releases 4.X) is a supported database-specific (backup/restore) procedure to perform faster Homogeneous System Copies.

Migrate to SAP ASE 16

Hi,
I tried to migrate from Sybase ASE 15.0.3 to SAP ASE 16 P3 on a Windows 2008 R2 server. Apart from the bugs in the Server Config tool we all
know from the old Sybase times, the migration of the database and backup servers was successful. Unfortunately, SAP ASE tools like DSEDIT and the new Interactive SQL don't work properly. I figured out how to get DSEDIT running but for Interactive SQL (aka DBISQL) I'm lost. Connecting to a
local server instance fails although local isql and remote DBISQL (ASE 15.7) work.
Did someone face similar issues in ASE 16 ?
Rgrds,
Mat

Matthias,
So is it safe to say migration from 15.03 to 16 is safe despite the nuances you outlines above ?

Online SAP testing environment

Hello friends,
I am looking for an online SAP testing environment site where i can do my FI configuration practice or alternatively a site where i can get free IDES software download so I can prepare myself for the industry. If you have an idea about how to solve my problem please help me.

Hi Srikrithi,
SAP Testing is all about test business process/functionality & outcome using manual/automation testing. For this I find knowledge of some Buniess Process/Functional Module must...but as you are alerady an ABAPer so must be aware of some of them. & Being ABAPer you will be better at White Box Testing. Do not take it as switching to testing & come back to ABAP dev or vice-versa; its just a matter of work responsibilities & your role in the organization. But yes...if you go for automation testing then must have knowledge of QTP or LoadRunner. Search more for term SAP TAO as well.
Hope this will help you to explore more.
Warm Regards,

SAP ASE Best Practice latest update

Hello experts,
just wondering if somebody already reviewed thoroughly latest guide for best practices on SAP Sybase ASE?
I am talking about the document from note 1680803 - SYB: Migration to SAP Adaptive Server Enterprise - Best Practice (former note 1722359 - SYB: Running SAP applications on SAP ASE - Best Practice).
The guide for normal runtime operation was merged with the guide for migration, but there are some contradictory statements.
Apart from that the study case is again designed for server with huge memory and lot of CPU cores (so not so real case normally, I wonder who setup so often such huge servers...), I have found some inconsistencies.
E.g. in part "Reconfigure Engines and Parallel Processing", they talk about to limit ASE engines to 16, but the command configures 32.
alter thread pool syb_default_pool with thread count = 32, idle timeout = 2000
No change to the previous setup for migration. Is this just typo? I understand it should be 16, and then also number of network tasks for normal operation would be 4 (as mentioned in the beginning of guide that normally you set up 1 per 3-4 engnes). If this is not typo, then number of network tasks is wrong as it should be 8.
Also they introduced idle timeout, but only talking about ERP and possible lower value for Solman - does this mean that for BW you keep default value (which if I am not mistaken is 100)? As per ADM540 you should even decrease this timeout when SAP system is sharing server with database - I know that document is old, but is again contradictory, not saying that it is wrong, but not well explained.
If anybody checked new version of guide, please let me know, I think it is bit messed up and is bit difficult to distinguish what you should set up for migration case and what for normal operation case.
Thanks!
Regards,
Matus

Actually, quite a few customers run with that many engines/memory.   In fact, it is difficult these days to even buy a server with less than 128GB of memory and 16 cores/32 threads.    Pretty much the only time we see less is when the install is in a VM.   Interestingly, we had comments from the first version suggesting the numbers were not realistic given the typical size of systems being deployed were much larger....    In addition, in my experience with customers on SAP systems, they were not aware of how much memory was necessary to really support medium to large systems based on the configurations they were attempting.
I am sorry that you feel some of the examples are contradictory. You are correct in pointing out that the text refers to 16 engines and the example configures 32....   So yes, for that specific example, it should have been 16.
Secondly, not having seen ADM540, but I think there is a bit of a problem if they suggest that.   I my opinion (and I have spent a lifetime tuning ASE), the idle timeout for ERP and BW should likely both be 1000+ and 2000 is not unreasonable.   The comment in ADM540 is likely due to if ASE and a NW CI are sharing the same cores - e.g. you have a 4 core box and ASE is running on 2 cores (we will ignore threads for this discussion) and you have 30 NW worker processes - which obviously will need to bump ASE off the cpu in order to run.   This may be fine in a test/dev or even a solution manager system, but bumping ASE off the core is NOT a good thing for a production system. In fact, I would encourage using numactl or similar to fence off the the cores used for ASE from NW worker processes if at all possible.   We have seen cases of overloaded NW installations with multiple CI instances with hundreds of worker processes each starving cpu away from ASE......sooo....I would tend to actually be a bit more than firm on suggesting that 100 is a very bad starting point.   Given the number of client side joins that SAP uses to avoid [DBMS proprietary] temp tables, it is critical that ASE's (or any DBMS) response time be minimized as much as possible.....having ASE yield the core practically as soon as it gets done processing one task (and puts it to sleep pending an IO) just really causes things to run slow.   Think of a typical query that returns 10 rows - say wide enough that each row fills 1 packet.   If the packet transmit time (and client ACK) takes more than 100 microseconds on CPU (almost a given for network interactions...as clock ticks are in nanoseconds and networking is minimally milliseconds - 1000 microseconds), ASE would yield the CPU every time it sent a packet.    When the client wanted the next packet, the OS would have to wake up the ASE process (an interrupted sleep) which is a nasty heavy weight operation.   Hence it is best for ASE to hang out on the CPU until reasonably sure that nothing more is going to happen very soon....and on current cpus...and having it run for 1-2ms (1000-2000 microseconds) shouldn't be a hardship.     If you created a separate thread pool for batch worker processes, then I could see maybe using a lower idle timeout such as 200 or 250......100 is just plain too low in my mind...it is like saying ASE is expecting an odd query every few seconds vs. a steady workload. Basically at that level, there had better be a task in the ASE job queue or one on the way on the network already, or that engine is going to sleep.
While I state that with regards to ADM540 itself, I have not seen the class (perhaps)...one customer did show me the notebook of a class (ASE Sys Admin) they went to and it was really targeted at non-SAP installations more than SAP installations - from a reality/experience aspect.   Part of the issue with the class the customer showed me was it borrowed liberally from the old SY classes as a starting point, but at the point the class was developed there was not a lot of experience with running SAP installations on ASE to really point out the fine tweaking areas such as idle timeout.
However, the document was really aimed primarily at Business Suite vs. BW systems or a Solution Manager install (which are much smaller) - there are a lot of other considerations for BW the guide doesn't get into - although some of the sizing is a better start than the defaults provided by SAPINST
The former runtime guide essentially was just merged in to the Post-Migration Steps section.
May do a quick refresh in the near-future (due to some recent experiences), so if you have other specific examples of the text and SQL not aligning - please let me know.

Homogeneous system copy on windows abap + java with a backup online

Hello gurus, I need to perform a refresh (HSC) from our production to our test system. we have a daily backup online that I want to use for restoring the test system .
from the procedure it's not clear how to proceed .
as my point of view i should say :
1) perform a restore redirect using backup online
2) export on the production the java side using database specific tools
3) import the java side on the restored database (when it stops to ask me to restore database i will use the backup created by the export procedure)
4) apply all the logs to the end of export of java to put the database in a consistente state
5) finish the procedure of import
my question marks are related to the step 2) and 3) . the restored database will keep the data of java side from the second backup (export) run by sapinst?
and.. do I have to apply logs till the export is finished to put db in a consistente state?
someone of you have performed it once ?
any advice is greatly apprechated

Hello guys,so just to be clear again
on the target system I have to execute
db2 drop database <SID> and following delete the content of sapdata?
I have seen on this website the possibility to execute the redirect restore using the comman "replace existing" . Can I apply this without deleting anything ?
ftp://ftp.software.ibm.com/ps/products/db2/info/vr9/pdf/letter/en_US/db2hae90.pdf
REPLACE EXISTING If a database with the same alias as the target database alias already exists, this parameter specifies that the restore utility is to replace the existing database with the restored database. This is useful for scripts that invoke the restore utility, because the command line processor will not prompt the user to verify deletion of an existing database.
For the java side , once the the restore redirect has been performed successful do I have to use the option for recreating the WAS AS JAVA only as system copy only? This will populate my java side correctly with the data of my exporting system?
best regards

How is SAP ASE doing?

In 2011, SAP announced it would become the No. 2 database player by 2015.
How is everything going with ASE so far?
Its road-map seems promising, is it gaining market share?
Product Road Map Updates

Hello Hank
The latest Gartner research (G00261660) into this "Operational RDBMS" area indicates that SAP have improved both their vision and ability to execute, moving it ahead of IBM on both dimensions (compared to previous quadrants)
From an SAP ASE perspective, I think that the roadmap today is probably the best I've seen.    The in-memory capabilities will further increase the strength ASE has in transaction processing, which is the focus for the offering - mission critical, high volume, low latency transaction processing applications.
Where things get even more interesting, is the work around HANA integration, and new work that is being undertaken to look at columnar technology for ASE.     This will add a whole new set of capabilities for ASE based applications - like geospatial analytics, graph engine, time series, or just plain old report acceleration.
Towards June, we expect to release a range of new capabilities that I'm sure customers and users of the products will love to get their hands on.     The Beta Program is well on its way for the Corona release.
Things certainly are promising.   From a market share perspective, analysts track vendor marketshare, not necessarily product level - here, SAP is growing rapidly, with a range of specialized data processing engines.
ASE specifically is enjoying really good momentum, with significant growth in traditional SAP accounts, as an additional database offering for on-premise SAP applications - which is a new market for the offering, outside of it's traditional strongholds in Financial Services, Public Sector, Telco and Healthcare.
If you're a Gartner, Forrester or IDC client, or have access to the latest data from these organisations, I would encourage you to read through these.
Alternatively, reach out to your local SAP office, or account manager, and set up a briefing, so we can spend some time with you!

Backup online redo log files

Hi All
Can you please explain for me the main reason that we do not have to backup the online redo log using RMAN ?
Thanks

The online redo logfiles are necessary to perform a complete recovery of the database. During database recovery, Oracle will apply the archived redo logfiles and online redo logfiles to roll the database forward and finally remove uncommitted transactions. If any of the online redo logfile group is active and missing, the database recovery will be incomplete and the database needs to be opened with restlogs, causing a new database incarnation.
You have to shutdown the datrabase to be able to perform a backup of the online redo logfiles, or find another method to create a time based snapshot of the data to prevent data movement while the redo logfiles are in use in order to keep datafile headers, controlfile and redo logfiles in sync. It is for that reason that you multiplex and mirror redo logfiles.

SAP Backup Service SAP 8.8 and Windows 2008 R2 64 Bit

Dear All ( Mr Gordon)
I am facing problem with the Backup Service on windows 2008 R2 64 Bit.
1)The Service starts - There is no Issue
2)THere is no Backup - Even though i schedule it perform the backup
3)EvenLog has a lot of messages - Messages says some Dll are Missing or Corrupt.
COmpletely Uninstalled the Server Tools and Reinstalled back ,still there is error.
PLease help !
Best Regards

Dear Dayal,
Thank you for your trust on me. To be honest, I never use SAP Backup Service. This is because: SQL Server provides its own Backup Service. No other vendor can compete with its build in function.
Thanks,
