Hi experts!
I need to remove log volumes. I have 7.7 version MaxDB. Is there any improvement in this version in comparasion to the previous process (backup and restore in a different configured db) of removing log volumes?
Thanks in advance...

Reset SAP* password
Hi All,
We have need to reset the SAP* password because SAP* (also DDIC) is locked on client 000 and we don't have any other user. We are on MAXDB (we have also SQL Studio) so we have the error "table unknown" when we try to excute the statement SELECT * FROM USR02 or SELECT * FROM SAPECP.USR02, where SAPECP is the owner. Obviously we want to excute the statement DELETE FROM USR02 WHERE BNAME='SAP*' AND MANDT='000'.
How can we proceed on MAXDB?

MaxDB database studio usermanagement errors
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

Tuning Redhat Linux OS parameters
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
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

Max DB start and stop
Hello Folks,
We have SAP system running on Max DB database. We have windows patching maintenance for that we have to stop SAP and Max DB database.
I am new to Max DB so can someone tell me the correct steps for stopping the database (including the service stopping sequence) and starting it again after the maintenance gets over.
We have two Max DB services running MAXDB: SID and XServer.
I checked on some document that states that taking max DB instance offline from Database manager is not a good idea.

POS(1) Unknown user name/password combination
Hi Experts,
We have installed an SCM APO server (EHP3 FOR SAP SCM 7.0) and the live cache 7.9.08.17 is on another box. We have recently refreshed the SCM system from QA, but LC has yet to be refreshed. We can connect to the livecache from LC10 but it says SQL access is not possible.
We have maintained the username and password in Integration for all the 3 connections.
Checking in DB59, for all 3 connections, LCA, LDA and LEA we are getting sql_neg: no_connection.
In SM50, its showing below error:
What I have noticed in other systems is that the user SIDADM is in upper case whereas in this server it is lower case. Will this cause this issue, and if so, how do I change the user to uppercase?
Working server (good server)
dbmcli on XXX>user_getall
OK
control
superdba
XXXADM
Server with issue:
dbmcli on YYY>user_getall
OK
control
superdba
yyyadm
Please advice.
Thanks,
Asad

Urgent - Sap MAXDB Support - Database slow and not responding to entries
Hi all we are running SAP MAX DB Version 7.7. We have about maximum 200 users at any one time. Recently we don't know what has happened but it is struggling to take in entries.
We have checked all hardware and network and at maximum is only operation at 50%. The database is struggling to take in data entry.
Querying data seems okay but slow.
What could the issue be and if someone could suggest a list of checklist will be great and hopefully a solution. Thank you.

-2 ERR_USRFAIL: User authorization failed
Hello guys,
First to mention my system:
OS: Windows 2003 server
DB: MaxDB 7_7_06_17
I have one problem to connect through Database Manager to one DB instance that just now I have installed.
What I want to do is to install one MDM server.
The bellow are the steps that were already performed:
-installed Java server with sapinst (this created its database ZJD)
-after this Java server was finished installed I started to create one DB MDM instance using SDBSETUP.exe
-I was able to create this MDM instance successful
And the problem is here: This MDM database instance that was created with defaults users DBA and DBM. When the creation of this MDM was finished I tried to connect with both Database Manager and DBMCLI to MDM instance using these users but I am not able to connect. I get the "-2 ERR_USRFAIL: User authorization failed" error. Can you tell me which is the reason?
I am sure that I typed the right user and password. I tried to uninstall all and installed again inclusive OS and the same error. I mention that to instance ZJD I am able to connect.
I tried with default users for Maxdb (DBA with pass: SECRET and DBA and DBM with pass: SECRET and DBM) but this doesn't work.
Can you help me to solve this problem?
Best regards,
Florin Radulea

Upgrading SAPDB 7.3 to MaxDB 7.6 - kernel.exe sharing violation / in use
Hello everybody,
currently an Upgrade of a SAPDB to MaxDB is driving me insane ;-)
Situation is: I am trying to patch SAP DB v7.3.0.34 (or even .42) to Max DB v7.8 (latest Build).
On the first try I was going through the upgrade guide for v7.5 since the prerequisite for later versions seemed to be v7.5. Then I found SAP note http://service.sap.com/sap/support/notes/793550 and the passage "We support the direct upgrade from 7.3.00 to 7.6.00 as of Version 7.6.00.12." From that point on I used the MaxDB v7.6.0.35 install sources to patch the Database.
I kept on following the guide for v7.6 to upgrade with the in-place procedure by using "DBUPDATE.BAT –d <DBSID> -u <DBM,DBM password>". The upgrade process started and now it keeps on quitting on me with the following error:
I investigated the issue and indeed while the Installer ist switching the DB modes the kernel.exe is running and you can see it in the task manager. Thing is: The kernel.exe remains in the task manager while the installer starts the phase in the screenshot above. Of course exchange of the executable is not possible while it is in use.
An error message is thrown and some moments later the kernel.exe vanishes out of the process list in the task manager. I tried to manually quit the kernel.exe in task manager, but it won't let me do it due to missing permissions.
I am logged in as Administrator. DB is in Admin Mode and X-Server and Windows DB-Services are stopped also.
Any ideas from your side? :-)
Regards and thank you!

Access to MAXDB SAP Schema tables
HI Guys ,
I am trying to reset SAP* password in my MAXDB DB 7.6. I know that is a very simple operation and I did it many times in other DBs , but here I have stuck during whole day .
I have connected to SQL Studio as SUPERDBA .
My SAP Schema is "SAPIDS" .
To access usr02 table I run the following SQL :
select MANDT, BNAME, UFLAG from SAPIDS.USR02 where MANDT='000' and BNAME='SAP*'
, but I got the error thet the table does not exist .
I also tried:
select MANDT, BNAME, UFLAG from "SAPIDS"."USR02" where MANDT='000' and BNAME='SAP* ,
select * from SAPIDS.USR02 ; select * from "SAPIDS"."USR02" ;
I switch to Oracle mode also , but Nothing is working !
Also important to say that sql :
select * from tables where owner='SAPIDS'and tablename='USR02'
shows the USR02 table as well .
Any ideas ?
thanks in advance,
Evgeny
