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 getting " liveCache lock server is not installed " error when we are scheduling a background job for programme:  SLCA_LCK_SYNCHOWNERS.  Any help is appreciated.

thx

Hello Colleagues,

I tried to install the SAP Max Database Studio 7.9.08 in a 64 bit version on a Windows 7 64bit (Intel) PC.

The newest version as SAP package "MAXDBSTDDSK7908_4-20006288.SAR" downloaded at Service Market Place.

After unzip with SAPCAR I executed the Setup "SDBSETUP.exe" with the default values.

Standard path "C:\sapdb\...

I tried es with different path like "C:\Program Files\sapdb\ ... with the same error situation

At SAPMax - XML Log Viewer I found serveral error's

ERR: Invalid value for type "path"

...

ERR: install registry not found

ERR: Cannot open install registry

...

ERR: Service check failed

ERR: Cannot open "C:\Windows\SysWOW64\drivers\etc\services" to write: No such file or directory

...

After check with "SAP Note 1097311 - SAP MaxDB Database Studio installation" I asume the issue is related to the Registry-Key path.

This ist the SAP requirement:

HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Windows \

SystemDirectory

Wert: "%SystemRoot%\system32" (type REG_EXPAND_SZ)

I have following values on the client PC:

SystemDirectory     REG_SZ     C:\Windows\SysWOW64

I don't think I can change the Windows 7 standard value/path here to the SAP value?!

Does anyone know the problem and how I am able to solve it?

Many thanks advance!

Jochen

Hello experts,

We are doing our SCM upgrade from 4.1 to 7.0 with migration. We have completed with the upgrade but before doing the LC upgrade we need to upload the data to the LC using the  /SAPAPO/OM_LC_UPGRADE_70, while doing this it gives an error for connectivity to the LC.

Hi Community,

for a few months I have been struggling with a  SAP Max DB database Studio issue and finally, I had to give up the idea of being able to fix this on my own. I am desperately seeking for help and I hope that you may be able to give me a hint, advice or even a solution.

This is what happened:

I used to run Windows 7 on 32bit. I also had Database Studio installed - which was running fine then.

After a harware upgrade, I am running now Windows 7 on a 64 bit System. All my files from my local disk (C:\) have been restored and copied onto my new system.

I reinstalled Database Studio Version 7.9.08.09 onto my new System.  Buton the first try to start the program I received the error that said "Could not Access to user Management.See Window -> Show View-> Event Log Viewer for more Details."

However the Event Log Viewer was empty.

After searching the web for a solution, I followed the advice given in this community and deinstalled Database Studio and deleted the C.\Users\MyAccount\sdb folder manually.

I reinstalled Database Studio and started it as Administrator.

However, the error is still appearing.

And, what makes it even worse is : now I am not able to uninstall Database Studio anymore.

When I run SAP MaxDB Installation Manager and select the instance of database Studio to be uninstallled I am receiving the error:

"ERR: Unhandled Exception: Can't call method: "GenPackageList" on an undefined value at SDB/Install/Gui/Dialogs/SelectInstance.pm line 328"

Any advice is highly appreciated.

Thanks,

Agnieszka

Hello,

Since two weeks I'm not able to start a NW7.3 System. After several checks I figured out that the database (MaxDB 7.8 on Windows) does not start. There were no changes in Hardware or OS, Kernel was not updated/upgraded. The System was running since installation in May 2012.

dbmcli db_enum does work:

But my problem is, that when I run dbmcli -u superdba,***** -d NWD db_online, there is no further reaction. Unfortunatelly the MaxDB logfiles (knlmessage etc.) were not updated, so I have no hint what I should check as nect.

Here you can find the whole discussion in Netweaver group: http://scn.sap.com/thread/3333896

So my question would be: is there any other MaxDB tool or log file, which can help me to solve this issue - or get at least a hint on the reason why the database can't start any more? Or maybe is an update to 7.9 a possible solution?

Thanks in advance

Hi,

I (succesfully, as far as I can tell) installed MaxDB on a Windows 7 Professional x64 Vmware virtual PC (maxdb-all-win-64bit-x86_64-7_8_02_28) and now want to also install MaxDB database studio (maxdb-studio-win-64bit-x86_64-7_9_08_01). While the installation seems to finish successfully, I'm running into errors after starting (as administrator). First error is

'Loading preference values failed; default values will be used

Reason:

Missing object type: :Loader'

then

'Could not read preferences

Reason:

Missing object type: :SQLSTUDIO'

The Event log viewer shows warnings about the utilities path not specified and again Errors about 'Missing object type:: preferences'

While Eclipse then starts up, it is not possible to work with the locally installed DB (which seems to be detectect, however). Again there are errors about

'Missing object type::preferences' as well as

'Could not load mounted Local Folders'

'Can not get registration preferences'

'Get login attributes failed'

'User management exception: Missing object tye::UM_CONNECTION_KEY_REPLACE_WITH_DATABASE_NAME'

Searching the web using these errors does result in too much help, , unfortunately, for UM_CONNECTION_KEY_REPLACE_WITH_DATABASE_NAME I do net get a single hit with google.

First I thought my Java SDK 1.7, is too recent, so I uninstalled DB studio and Java and tried again with Oracle jdk-6u37-windows-x64, but I'm getting the same errors. I also noted that, as it seems, the DB Studio remembered the password from the previous installation. It did not ask for a new one during the new installation but asked for the old one after I started it (I consider this a bug).

Any ideas anyone? Any help would be appreciated.

Maybe I should also note that at first I had a broken MaxDB installation (it failed to load the system tables), which I uninstalled, however and reinstalled (then succesfully).

Thanks in advance and best regards,

Thomas

Hi,

I got a new powerfull "client" machine installed with Windows 7 64 Bits. Also i installed the MaxDB tools in 64 bits version.

Naturally the machine where the database is is Linux MaxDb 64 Bits (version 7.6.06.10).

I do use a lot MS Access 2010 since months, on the previous machine that was Windows XP, il was Office 2010 32 bits. Here naturally, i have Office 2010 64 bits. I'm searching for the ODBC drivers in 64 bits version, but always see the 32 bits version, does the ODBC 64 bits drivers exists ?

F.B.

Hello,

I installed the Database Studio 7.9 for MaxDB (my version of MaxDB: 7.8.02 Build 31) and I don´t know why but everytime I try to run it that returns an error:

I installed the Java that is recommended in SAP installation guide for MaxDB (Download Free Java Software) and then I set the JAVA_HOME environment variable for user <sid>adm and also I add the path C:\Program Files (x86)\Java\jre7\bin to PATH environment system variable.

I typed the following command in way to check the Java version that is installed on the server:

C:\>java -version

java version "1.7.0_51"

Java(TM) SE Runtime Environment (build 1.7.0_51-b13)

Java HotSpot(TM) Client VM (build 24.51-b03, mixed mode, sharing)

C:\>java -fullversion

java full version "1.7.0_51-b13"

Can you help me please to figure out what's the problem and the solution for this for I can start the database studio application?

Kind regards,

Hi there,

We have a production problem at the moment as follows: A WAS Java is running on MaxDB (7.5.00.32; I know, it is old), had no issues for years.

Now, since 12 days, the system halts every morning, due to the DB not answering any more. On the DB side, normally (after a WAS / DB restart), the DATA area is filled up to 79%. We observed now that during the issue, this goes up to > 95%. So I expect this coming from results, as this space gets free after a restart immediately.

We also had a bad design for the DATA area (one DATA file with 15GB). We will change this within the next hours to 5 * 5GB DATA files, removing the 15GB DATA file afterwards. That should (a) offer more parallelism (we see many IOWaits and "IOWait(R)(041): b13get_node: await read              :-(" during the critical situation), and (b) offer enough space.

If this succeeds (any additional thoughts welcome), I would like to analyse which statements lead to big results, as probably this is what has changed 12 days ago. Question: How to check this?

Thanks in advance

Hi,

I am new to MAXDB and installed SAP system on Windows XP on local machine.

I have installed SAP Netweaver and while connecting to MAXDB via MAXDB Database Manager facing issue.

I am getting error as -2 ERR_USRFAIL:User authorization failed. Please check attached screenshot for more details.

I tried to connect via credentials provided in this thread http://scn.sap.com/thread/95219  but failed to do so.

I used following ports for connection:

           7200

           7210

           7269

           7270

           7575

Can anyone provide port, default username and password.?

Feedback appreciated.

hi,

We have recently started upgrading our systems to LiveCache 7.9.08.16. I am thinking of introducing Log partition to speed up the log writing to log-area.

I think, this would help to avoid Log-queue overflow in case of high load. Wondering, if this feature would help any other way to justify making changes.

Will it any way help reduce the batch-job run time window in normal load?

Would appreciate for any additional information on log partitioning.

Thanks,

Raj
