Error "-9400 AK Cachedirectory full"

$
0
0

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.

[-9205]: System error: AK Catalog information not found / CONSTRAINT

$

0

Hello all,

 

We get the following error (in MaxDB Version 7.7.06.09):

 

    [-9205]: System error: AK Catalog information not found:00000000000037BD000A0011

 

... when reading the constraint definitions for a specific table like this:

 

     select * from constraints where tablename='TABNAME'

 

This error happens since we made some meta data changes as follows:

 

   rename column TABNAME.A to B

   alter table TABNAME drop B

   (also some other columns were added and some removed from table TABNAME)

 

I guess that this error happens because the statement "alter table TABNAME drop B" did not properly drop a constraint definition that should be removed because column 'B' was part of the constraint definition. It seems that the check for depending constraint definitions that usually removes these when a column is removed contained in the constraint definition, does not apply in some specific cases, probably because of a specific rename/add/remove-sequence.

 

I guess a workaround is to remove all depending constraint definitions manually, BEFORE the column is removed.

 

Unfortunately it seems impossible to do so afterwards.

 

Thanks for any comment on this.

Hi MaxDB experts,

 

Can someone explain the procedure for resetting password for CONTROL or SUPERDBA user for SAP MAxDB.

 

Scenario: Both CONTROL(DBM user) and SUPERDBA(Admin user) are forgot or locked(MaxDB is being used for content server in our case).

 

I have gone through the below notes, sap blog and many scn discussions.

 

25591 - Password change for DBM and DBA users


User Profile Container - MaxDB - SCN Wiki


I did so much of experimenting on this and still unable to get a straight way to get these passwords reset. If someone can throw some light on this.. that would be much appreciated.

Hello Experts!

 

 

I've successfully installed NetWeaver 7.3.0. For Webshop purposes, I'm trying now to deploy wec-komponenten because my target application is WCEM3.0. At the the step "checks" I face following issue:

 

 

An error has occurred during the execution of the Check DB free space step.

 

Could not complete DMT process. Check the DMT.LOG log file. Could not execute DMT command runhandler. See previous messages. The dbmcli process could not be executed. Could not run OS process dbmcli for action CHECK_NEEDED. Could not start process dbmcli. Error while executing process dbmcli. java.io.IOException: CreateProcess error=2, The system cannot find the file specified java.io.IOException: CreateProcess error=2, The system cannot find the file specified.

 

I'm logged on as NetWeaver User. In the commando of the DB, I can run the dbmcli code to find information about the DB

 

The file CHECK-DB-FREE-SPACE_02.LOG gives me almost the same message

 

Can somebody tell me what is wrong with my system?

Hi Folks,

 

I want to inform you about a newly created section in SCN wiki

 

 

http://wiki.scn.sap.com/wiki/display/MaxDB/SAP+MaxDB+Log+Files+7.9

 

Now you'll find at a central location in SCN a collection of all SAP MaxDB log files (up to Version 7.9). The collection contains a short description what the specific log file is used for, in which directory you'll find them and  if necessary how to convert them. Additionally you'll find links to further relevant documentation.

 

This could be the starting point for error analysis of any SAP MaxDB database problems.

 

Feel free to give feedback if you are missing information.

 

Regards, Christiane
