Hi,
we have a rather strange and hard to track problem with corrupted databases.
Our setup is:
* Docker container with a Tomcat that hosts BaseX with some custom
RESTXQ services
* BaseX 9.2.4
* Java 14
* Docker runs on a Linux VM
Workflow
* Create database with RESTXQ service call
*
Hi Vladimir,
The DBPATH option is the one you’ll need to assign. As it’s a global
option, it should be assigned at startup time [1].
Best,

I am evaluating BaseX for my XML project.
I need transaction support like
-Start transaction
-Run queries (read, write, update)
-Commit or rollback transaction
When I see the documentation, it lists Transaction Manager. But when I look at
the details, I cannot find
Right, the option is global. As BaseX has been designed to serve concurrent
requests, it would introduce unexpected side effects of the path was
changed at runtime.
If you are careful, you can try to change the path by assigning a new value
to Context.soptions.

Hi Reto,
AFAIK Basex is transactional in the sense that whenever you start a
sequence of commands or an XQuery script, all the "updating operations"
that modify the database are always stored in a PUL (a list of potential
updates).
Only when the script terminates all the operations on the DB
Ah no, I'm not talking about changing it in runtime, I'm talking about
specifying the path on database creation,
for example when CreateDB command is executed. There shouldn't be
concurrency problems at the moment of database creation, correct?

Hi Marco
Thanks for answering
But that means Basex is NOT supporting database transactions
Or is it possible to implement real transactions (START TRANS, do something,
COMMIT trans) with that PUL or something?

Yes, I've seen that option.
But there is no way to set it per database, correct?
I'm asking because by nature our operations are ad-hoc, we don't really
"startup" the instances,
we create a database, process the data, then destroy the database.
Is there some internal limitation why this option
I've found that when I perform a database optimize on an unoptimized
database that while the record count decreases as expected, the database
size (bytes column) stay the same. Is this a bug in reporting the database
size (less severe problem) or a bug in the database not reducing on
optimize
Here are steps to recreate the problem:
(1) Add one or more entries to an new (empty) database. One the BaseX
Database Administration's Database page, you'll find that the database's
COUNT column shows the number of entries added and that the database's
BYTES column shows the database size.

Hi Geoff,
Did you run OPTIMIZE ALL or db:optimize(..., true()) ? What do you mean by
"record count"?

On the BaseX Database Administration's Database page at
https://localhost:10443/BaseX/dba/databases, I selected a database I knew
was unoptimized and pressed the Optimize button. The database's COUNT
column decreased to the number entries in the database as expected.
However, the database's
It's surprising that the count value changed, as it should represent the
number of resources (documents, binary files) in your database – and this
value shouldn't change if your data is optimized. Feel free to provide us
with a little reproducible example.
The size of the database may stay the

I would think so. Let me see if I can create a small example using the
BaseX WEB API that recreates the problem.

If I replace the document via the DBA, or if I run an update expression via
the Queries Panel, the count always reflects the number of resources, it
doesn’t change.
How did you update the document? Is it an XML document or a binary file you
