Hello,

I have a question concerning NAGIOS. We monitor our productive systems with NAGIOS. Therefore a user NAGIOS is created to monitor the system. With this User NAGIOS connects to the system and monitors the system. We have the phenomenon that there are hanging NAGIOS sessions on our BW system. There are multiple Login sessions of the User Nagios. I can only resolve this issue by logging out User NAGIOS manually from the system.My question: Why does the User NAGIOS connects more than once to the system ? Why are there these hanging NAGIOS sessions ? How can this be prevented ?

Kind Regards

Hello,

till now it was possible to update statistics via the reports RSADAUP1 - 3 . In new releases it is obsolete as SAP changed the DB13 behaviour.

But we still want to use them.

Why? We have an external Job Scheduling tool which shall start and check the whole statistics updates. So we started the Report and got a return code from it.

So how to start it without the report?

We dont' want to use the DB13 itself.

Thanks

Jan

Hello,

I'm writing back following an old thread in 2009 on this forum, related to a problem with MaxDB and "AK Cachedirectory full" problems. You can find the previous thread here: What can we so against Error "-9400 AK Cachedirectory full"?

The problem was actually never resolved: we could more or less live with it, and we managed to reduce it for a while, but we are having that problem again almost every day now. We actually fixed various points since 2009 and our system has changed quite a lot.

We use MaxDB 7.8.02 (BUILD 038-121-249-252) with the JDBC Driver sapdbc-7.6.09_000-000-010-635.jar. Note that we don't use MaxDB in a SAP environment as we have our own business application.

Following some very helpful feedback from Lars Breddemann, we fixed various points in our system: for example, result sets were not always properly closed, this is now done immediately after the query has been executed and the result rows were read. We also follow the advise from Elke Zietlow to always close a connection and its associated prepared statements when the error occurs. This also helps in most cases, but sometimes when the error occurs, even closing the connection and its prepared statements does not help and the problem "escalates" until we have to restart the db to fix the problem.

Back to the discussion in 2009, I used the two statements given by Lars to monitor the catalog cache usage: when I run this multiple times, I see that all result sets are properly closed as I only see the ones currently being used and they disappear.

One important point is that our java application keeps many prepared statements open in a cache, to have them ready to be reused. We can have up to 10'000 prepared statements open, with up to 100 jdbc connections. Actually the AK Cachedirectory full problem happens sometimes very soon after we restart our system and db, so at that time the number of prepared statements can be very low, which seems to indicate that the number of prepared statements being open is not necessarily linked to the problem.

Also in the discussion in 2009, Lars mentioned the fact that we use prepared statements of the type TYPE_SCROLL_INSENSITIVE and he was asking if we could not use TYPE_FORWARD_ONLY. Would this really make a difference? We need the TYPE_SCROLL_INSENSITIVE in many cases because we use some iterators to scroll up and down the result sets, so using TYPE_FORWARD_ONLY would require changing quite some code. I also saw in the MaxDB code that using the type TYPE_SCROLL_INSENSITIVE adds the string "FOR REUSE" to the sql statement, what does it exactly mean?

Amy help to fix that problem would be greatly appreciated.

Hello,

I've been reading the following notes:

Note 487972 - Tuning Livecache to the Linux OS

Note 767635 - MaxDB Version 7.5 parameter settings for OLTP/BW

Note 337445 - liveCache and memory management

Note 487972 - Operating system parameterization of liveCache

Note 941735 - SAP memory management for 64-bit Linux systems

There does not seem to be any Redhat specific tuning settings (though a couple of Suse recommendations), except for a general mention of all Linux systems with this direct I/O suggestion:

"As of Linux Version 2.6, we recommend that you set the parameter to the value YES rather than DEFAULT NO.

Further notes on this topic:

Note 977515:. Linux System paged during MaxDB data backup/add volume"

The parameters I am wanting to tune are in /etc/sysctl.conf, so since there does not seem to be any Livecache specific parameters, I was going to just take the general recommendations from Note 941735 - SAP memory management for 64-bit Linux systems and set our parameters as follows:

- kernel.shmall

As a configuration recommendation, kernel. shmall can be configured as the amount of virtual memory in the Linux system (RAM + Swap).

- kernel.shmmax

           This kernel parameter specifies how large an individual SysV Shared Memory Segment is allowed to be. In the case of an STD implementation, the parameter must be set sufficiently large in order to allow em/initial_size_MB. The value is specified in the unit Bytes so that "21474836480", for example, permits segments of 20 GB.

I am thinking to tune kernel.shmall to 90% of RAM+swap, and kernel.shmmax to 90% of RAM. Also will be setting the following parameters as well:

kernel.msgmni=1024

kernel.sem=1250 256000 100 1024

1. Parameter kernel.sem corresponds to "semmsl semmns semopm semmni"

vm.max_map_count=1000000

Does anyone out there have any different experiences or tips on how they set these up, specific to Livecache? The SAP application tuning is pretty straightforward, but wanted to make sure we didn't overlook anything with Livecache.

Thanks,

Derek

We are using MaxDB for Live Cache. We are using Version 7.9.08.08 and have logshipping to the DR Server.

Currently we have 7 data files:

DATA0001 6,291,456 KB FILE /sapdb/L1P/sapdata1

DATA0002 6,291,456 KB FILE /sapdb/L1P/sapdata2

DATA0006 6,291,456 KB FILE /sapdb/L1P/sapdata6

DATA0007 6,291,456 KB FILE /sapdb/L1P/sapdata1

The filesystems have been sized at 35GB each.

Today we fpounf that the filesystem /sapdb/L1P/sapdata1 has become full and when we view the filesystem we see the following:

Hi Everyone.

I am recovering a Content server database as part of the upgrade process of Content server 6.40 (32-bit) to Content server 6.50 (64-bit).

The source database version is MaxDB 7.5.00.51, the target database is version is 7.9.08.08. I am using DBStudio version 7.9.08.25 and following SAP notes 9620109 and 129352.

I have created backups of the source system using the DBStudio and transferred the files to the target server. I can recover the SDB database without any issues, however when I try to recover the CDB instance I get the following error:

Am I missing something? The file definition is the same for both the source and the target.

Thanks

Hi,

I have installed SAP Netweaver developer Studio 6.40 which installed MAXDB database also. Due to some reason I had to unistall the trial version of Developer studio, in this process developer studio got unistalled but not MAXDB.

*----

I use Add/Remove programs and uninstall MaxDB. I get the messages like this.....

Start uninstallation now (y/n) : Y (resoponse)

then message displays

found instance of J2E, cannot remove package..first remove all instances...

*----

I have stopped all the services, even then Iam getting such error message. How do I uninstall?

Help needed.

The maxDB database is not starting,

When I type

dbmcli -n mgiusdgrc1 -d CME -u superdba,<passwd> db_online, I get the following error.

Error! Connection failed to node <hostname> for database CME:

-24700, ERR_DBMSRV_NOSTART: Could not start DBM Server.

-24832, ERR_SHMNOTAVAILABLE: Shared memory not available.

-24827, ERR_SHMALLOCFAILED: ID E:\sapdb\data\wrk\CME.dbm.shi, requested size 260010,

Opening shared memory file E:\sapdb\data\wrk\CME.dbm.shi failed, rc = 5.

I tried to rename the file CME.dbm.shi, but it did not work.

Currently we have 8 GB of physical memory RAM allocated on Wndows 2008 Server and paging size specified is 16 GB.

1- Can anyone help in resolving the above shared memory error?

2- Are there any logfiles and specific error messages that I need to check, to resolve the MaxDB startup issue error.

Thanks in advance.

Hi SCN,

I've worked on and off with SCM/APO systems and MaxDB liveCaches for years now, but I've never come across this quirk.

As part of our standard operating of MaxDB liveCaches we always use TIME-BASED Automatic Log Backups. We set them to backup every 10 minutes (see image below). I've not had any issues with this but during a system migration I've noticed that the logs are NOT being generated every 10 minutes on the target and I wondered to myself if this is because there is no activity yet?

i.e. should it keep automatically generating new logs every 10 minutes even if there is no activity?

If not then, and here is the KEY QUESTION, how can I check the Automatic Log Backup settings that are active?
I'm assuming there is a simple DBMCLI command for this but I haven't found it yet/

Appreciate any community advice!

Many thanks,

Jamie

This used to work with 7.5 version driver. Why this is failing with 7.6 driver, any clues?

Thanks,

Vinod

Thanks for your help

Hi,

I've installed Maxdb 7.6.03.10 version 64 bits in the  windows server 2008 R2.

I've installed "maxdb-odbc-setup-7_6_00_12" for 32 bits too.

My problem is about the ODBCAD32. When  i run ODBCAD32.exe and i do a new connection in System DSN  then i select a  MAXDB (unicode) 7.6.00.00 and  i've an error :"this application uses CTL3D32.DLL,which has not correctly installed CTL3D32.DLL must be installed in the windows system directory"

I've copied "CTL3D32.DLL" of sysWOW64 directory to c:\windows\system32 , but i've the same error.

I need run ODBCAD32 because the applicaion of delphi is of 32bits and also go to find the ODBC of 32 bits.

Could you help me please.

My regards,

Isidre

Hi Gurus,

When i tried to start up the data base i'm getting an Error -24988 SQL error [db_online -f]; -902, I/O error.

Windows Server 2003 R2 X64 Bit;

Max Database Manager 7.5.00.18

The following is the data base error log file.. Please let me know if there are any other logfiles and specific error messages that I need to check, to resolve the MaxDB startup issue error. Any help would really appreciated.

Regards,

BI Learner.

Hello everybody,

We have recently migrated our Production system from Oracle to MaxDB, and encounter several occurrences of the message hereunder every day.   The OS is Win2008 Std x64 SP2, the DB version 7.7.07.09...

From what I saw, the errors are often - though not always - related to processes from the "BI light" add-on that was implemented on our ECC system.

Is this something we should worry about, and if so, any idea on how to fix?

Moreover, I detected these errors after a Production DB kernel abort we had yesterday.  The crash had something of what's described in Re: MaxDB 7.6.05.09 Kernel aborts - EXCEPTION:'Access violation' (0xc0000005) , but I'm not sure if there's any relation with the message hereunder...

Thanks in advance for any clarifications on this subject,
