Hello,
Due to an upgrade from ERP 6.0 to ERP 6.0 EHP5, I had to add new data volumes to my MAXDB database.
I created 6 data volumes of 9.5GB and 2 data volumes of 38GB.
i am not too worried about the 9.5 GB data volumes since they are close to 50% free.
However the 38GB data volumes are filled to only around 13%. This consumes a lot a space on my server.
Is there anyway to reorganize the database? I need to free-up some space on the server.
I am new to MaxDB.
Thanks,
Suhan Hegde
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...

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 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.

Hello All,

i have installed the latest version of SAPMaxDB studio for desktop - and installation was successful. When i try to launch the db studio, nothing happens.. no message whatsover.. Can someone guide me to launch it
Good day;
We are trying implementing the latest SAP LiveCache release.
Unfortunately, we canu2019t do this since the password of users control, superdba, and other maxdb database default users are not known. This is becoming a real problem by time since no one can login to this database using the database manager application, hence, no one can administer this database properly.
The LCA, LDA, LEA connection between SAP SCM instance DSC and liveCache instance DSL, however, are already set up correctly and connection is healthy between DSC and DSL but the password used for this connections is unknown.
Is there any way SAP could help us on recovering the lost passwords of the users control and superdba without the need to trash the liveCach database and recreate it again as this is not acceptable by the
business users.
Thanks,
Ahmad,,,

Hi,
How do I use for all entries for the internal table of table types without fields?
I have table type CRMT_OBJECT_GUID_TAB which has line type as data element, so does not have any fields.
Example:
data: lt_guid type crmt_object_guid_tab,
lt_customer_i type table of crmd_customer_i.
select * from crmd_orderadm_i into table lt_guid .
select * from crmd_customer_i into table lt_customer_i for all entries in lt_guid
where guid = ?????
What should I write here in where condition?

Sagar
