Hi there,
I have defined a DB table with different fields, one of these is field COMMENT, type set to string, Dim to 1024, that means real type Varchar (when controlling via SQL Studio; within the DDIC Project in Netweaver Developer Studio, it says LONGVARCHAR), code is UNICODE, Not Null not set.
When I insert a row and there is no comment, an empty string is set for COMMENT. But this throws a com.sap.sql.log.OpenSQLException: Cannot assign an empty string to host variable
Why this?
When I control the string before and set the field to null instead of the empty string, it "works".
Thanks in advance

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 experts, we seem to have a damaged file in one of our cache servers. The original file is stored in a content repository far away from my location. It seems to be in the cache server of my location, because it is delivered from there ( I can see it in the tracefile). But, it gets checked out with a file size of 0 byte (it should have 127 KB). When I use the LCA parameter to simulate that i´m in the location where the file is stored, it can be checked out as expected (without caching directly from CS). Did anyone see such a situation? Is there a way to "renew" the specific file in my local cache server? Or, is there a way to delete a specific file in the cache? Any other ideas or workarounds? If not, I would have to drop the complete data inside this cache server. This is not really a problem, since the cache would rebuild itself again. Just if there would be a more simple solution. Thanks! Martin
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
Hi,

Hi,
I had an old version of MaxDB Studio 7_9_08_01 which was running very well.
Since a couple of days, the studio desn't want to launch anymore. I can see the process coming up in Task Manager and it dissapears.
I have also tried using a newser version MaxDB Studio 7_9_08_32, but no change.
I have see some XServer in the services which is related to MaxDB, does it needs to be running?
Thanks for your help.
Hello Everybody
We use MaxDB for our SAP Systems and non-SAP Applications.
On one MAXDB Instance(7.8) we have a group AAA and a user BBB that belongs to that group.
The user BBB can create,alter,drop tables and of course insert,delete,...
Wenn looking at the tables(more than 500), the schema is AAA and the owner is AAA
All own applications connect with user BBB.
(the database administrator who build the database more than 10 years ago left the company!)
Everything works as expected.
With SQL-Studio(7.6) we can connect as user BBB, select the schema AAA, see all the tables and do anything we want.
With Maxdb Maestro(another MaxDb Gui) we can connect as user BBB, select the schema AAA, see all the tables and do anything we want.
But with the new DBStudio we only can connect? We can't select the Schema AAA and we don't see any table that belongs to that schema?
What do we miss? What is the difference between SQL-Studio and DBStudio?
We would pefer to use DBStudio in future.
Any help welcomed.
Best regards
Albert

Hi Maxdb world.
This is my first post, so please be gentle. We;ve been running Maxdb on HP_UX for Content server for a number of years, and it remains on version 7.7.
However, as part of a drive to remove ORACLE DBs from our landscape, we are attempting to migrate all our Java instances to Maxdb 7.9. I've done the first one ok, but I can't get it to add to the Database manager tool so I can 'manage' it'. The tool is version 7.6.
So, my question is, has the database manager tool been replaced by Database Studio? Or, is the an issue connecting to a 7.9 database from a 7.6 tool, and is there a newer version of this tool available?
Thanks
Bill Dedman
Hi MaxDB People
Here is my second post/question. Hopefully somebody can help me out here.
I've installed a MaxDB database, and performed a Database migration from Oracle to create a SAP Java ADS instance called AQ3.
We use HP Service guard clusters, to allow us to move instances around between server nodes. Because if this, I have configured the file systems for the database and software as follows:
Node 1 (where the original install took place)
<Local to the server node>
/sapdb
/sapdb/data
/sapdb/programs
/sapdb/clients
<Installed as a movable package called 'sapaq3' and mounted in bold>
/sapdb/AQ3/ <and all subsequent directories>
/sapdb/client/AQ3<and all subsequent directories>
/usr/sap/AQ3
/sapmnt/AQ3
On the original server node this instance runs just fine.
Node 2
I installed the MaxDB software again locally
/sapdb
/sapdb/data
/sapdb/programs
/sapdb/clients
I then moved the package 'sapaq3' to run on node 2
/sapdb/AQ3/ <and all subsequent directories>
/sapdb/client/AQ3<and all subsequent directories>
/usr/sap/AQ3
/sapmnt/AQ3
I started the x_server from /sapdb/AQ3/db/bin
When I try to start the database however, I am getting the following error message:
dbmcli -d AQ3 -u control,xxxxxxxx db_online
Error! Connection failed to node (local) for database AQ3:
database instance not found
I'm thinking there must be some need for a database registration on node 2, so that the central software knows about the database that has been previously installed elsewhere. I tried the sdbreg command but I am still getting the error.
Does anyone have any idea what the issue could be?
Thanks everyone.

Hi All,
We have Build DR Standby System which we have restored from Prod System into a Standby System.
We have used the Log Shipping Script which is available in the below wiki Link
HowTo - Standby System (Recovery from Log Backup) - MaxDB - SCN Wiki
Our SAP Landscape Environment is Windows OS 2008 and MAXDB 7.6
Well, This Script consist in 3 files: Standby.Bat, Recovery_Builder, Recovery_Apply. We have implemented these scripts in STANDBY SERVER,
We've tried to adapt the code for our system landscape but when we execute the script we're running into an error:
And we are facing issue in the 2nd Script RECOVERY_BUILDER, As per the script it will Set DB to Admin mode and then builds the import list and exports to script file.
I have tried this script but no success i.e i cannot generate the Script file, The Script is Working till : EXIT LOOP
Please find our adapted Script with changed LOG Path, DBMCLI, Passwords
RECOVERY BUILDER :
rem %%a = Logfile Name
rem %%b = log file number
rem %%j = Page number
Set LiveDB=SAPDMSPRD.domain.com

pause
goto exit_loop
)
:end
The Live DB variable is PROD Server Hostname FQDN
LOG Backup Path = Z:\DR_DataBackup\Log_Bkp
Backup_Medium_Label = SDB_log_bkp
I have run the script manually with 3 log files generated manually, The Script is giving me values of Current USED log page and LAST LOG PAGE,
After this EXIT LOOP the script comes out of loop and doesn't generating the script file.
Could you provide me what are wrong in my adapted scripts and help me with them??
Thanks,

Hi everyone
I have SAP Solution Manager 7.1 On Linux suse 11 and MaxDB 7.8 with SID ZZZ. The password of dba user SAPZZZ was changed.
The old password was for example'XxHh$115' (with special caracter $) and the new password is 'XxSYy2015'.
I change the password in Database studio following the instructions of the sap notes:
25591 - Password change for DBM and DBA users
39439 - XUSER entries for SAP MaxDB
The change of the password was succesfully.
I obtain an error in the transactioN DB13 and using dbmcli command:

I try to change the password via dbmcli with the following command:
dbmcli -u SAPZZZ,XxHh\$115 -uk DEFAULT -us SAPZZZ,XxSYy2015 -d ZZZ -n hostname_xx
but the error is: Error! wrong username or password!
Database studio is working fine, I can to execute backups with the user SAPZZZ.
Please help us to solve it, I need schedule the database backup using the transaction DB13 but the job ended with message: -24950,ERR_USRFAIL: User authorization failed.
Thanks in advanced for your help.
