Hello All.

After restoring the DB while i m trying to bring the SAP Instance up, i m getting "DB-Connect Failed, Return Code 000256" in Syslog.

Can anyone tell me how this can be solved.

The DB is MaxDB 7.6.05.15 & SAP ECC 6.0.

Thanks.

Regards,

Mudassir.Imtiaz

P.S I tried to add the Developer Trace with this message but somehow i couldn't.

I guess its exceeding more than 15000 characters.

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!

Regards,

Jochen

Hello,

We backup our production system with a ksh script and dbmcli commands. Blocks are written on a named pipe in order to split destiantion file into 1Go pieces. The backup has failed last night. In the KnlMsg, I have :

_LINE=3175

....

I can copy a file manually trought a named pipe, I guess that the problem is not at OS level.

I have scheduled a check data this week-end. What can I check ?

Thank you,

Hei,

I need for a migration project the ODBC 32 bit drivers for Windows as best as version 7.8.02.28.

I tried version 7.8.02.41 but had some problems.

Can you please upload the drivers somewhere?

Thank you.

Greetings,

Manuel Kuhn

Hello

After migrating a sapdb instance (7.3 system) to maxdb 7.6 I have problems with the superdba and the control user.s The password that I think they should be the right do not work.

Now I'm looking for the possibility to reset the password of superdba and/or control user.

Please do not send me the notes

25591 - Changing the DBM, SYSDBA and DBA user passwords

and

39439 - XUSER entries for SAP DB and MaxDB

as done in many other SDN threads. This doesn't work for me because you can change the password only if you know the actual password (standarlogins superdba/admin and control/control do not work btw).

Does anyone know how to reset those passwords?

Thanks and regards

Marco

I folks,

I use a 32 bits IDE witch connect to MaxDB using ODBC, so i need the 32 bit driver to create a 32 bits ODBC datasource.

Everything was OK, until ia receive a brand new computer, running... Windows 7 64 bits.

When i try to install MaxDb client (7.6.06.22), i have this message:

Cannot create package tree: unresolved dependency: package "Database connectivity" not found.

I've also tried version 7.8.02.21, and i get another message:

Software isn't runnable on your system.

What must i do ?

TIA

Frédéric.

Dear all,

we performed a remote homogenous System Copy MaxDB on Linux with Backup/Restore procedure. The "recover_start <medium> DATA AUTOIGNORE" succeeded with RC=0 (8-time parallel backup files).

When we try to start the Database with "db_online", the process won't terminate and the Database stays in state "ADMIN". KNLMSG doesn't get new entries, the last ones are:

"db_cons show task" shows one interesting task

--> what is he waiting for?

"param_checkall" says OK.

Any helpful hints will be greatly appreciated. The target Database Release is the same as in Source: 7.8.02.035 (we took the 7.8.02.031 installation package and patched it).

Kind regards,

Dirk

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.

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

Dear Experts,

We are Migrating our ECC6EHP4 system from Solaris5.10 with Oracle 11G to RHEL 6.4 with MaxDB 7.8.02 and the DB Size:480 GB, and we are facing issues in Import ABAP Phase as below: Please help us

we have started the Import ABAP phase by importing packages in order by size

The import ABAP job of package BSAS,D010TAB,SAPSSEXC_2 is running from more than a day and it is not writing any logs and some times it is writing logs after several hours  and it is not throwing any error.

we have checked the DB side there is sufficient Data area and log area is available and there is no issue from DB side.

Please help in this case what we can do analysis from the DB side or SAP import side. We have used the source and target systems same kernel with latest R3load, R3ldctl,R2Szchck patches. in this case what we can check the other logs if any thing is available please help us

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.

Good day,

I am busy with a Unicode Conversion project which involves MaxDB and a System Copy.

During the import and installation of the target system we had several issues relating to parameters not being correct in MaxDB. This caused huge delays in the whole process and unnecessary downtime.

To avoid having to do these parameter changes after waiting for the target install to fail once it has built the database I want to pre-install MaxDB and upgrade it with the necessary parameter changes so that we can avoid issues experienced during the target installation and import of data. I also want to avoid having to wait for 1TB of database volumes to be built during the target install.

My question is then, where in SWPM or what is the best method to use to pre-install MaxDB so it can be used for SAP ? I do not see any option in SWPM to install MaxDB as a standalone database. Note, this is not a distributed system, just a standard Central instance installation. I just want the option to install and configure MaxDB first.

We will be using MaxDB 7.8 since this is what all databases are using in the landscape. After the Unicode Conversion we will upgrade to 7.9 and install the latest enhancements. I have the installation media for 7.8.02.31 - this will be patched to build 41 before the import.

Thanks.

Nelis
