ogging for derby, there doesn't appear to be any indication of what's
going on.

I've got a process that creates a bunch of temporary indexes, then does
some work, then drops the indexes. All of these indexes are on different
tables but in the same database. During the drop the indexes phase, i
frequently get dead lock warning messages, each drop index statement seems
to be blo

Sometimes when my app starts, it can take several minutes to initialize the
database. Is there a way to find out whats going on? There isn't much log
output. I have overridden derby.stream.error.method but other than the the
startup message, I don't have much to go on.
Is there perhaps a startup d
Perfect, thanks

Are there any maintenance procedures I should be running after each purge?
Postgres and mssql has some functions to tell it to recover disk space and

yup, definitely a blob. it looks like the like operator doesnt work for
blobs, or maybe i need a cast or some function to the conversion

I have a use case where i have string data stored in a blob and i want to
perform a query similar to
select * from table where column1 like '%hello world%'
It doesn't look like this is possible with derby out of the box. Is there a
way to create a function that calls a java function or something

There is a NetworkServerControl#getCurrentProperties() method. Can i inject
the javax.net.ssl properties through there before starting the server?

Is there a particular reason we can't do indexes on long varchar columns?
Is it possible to (from the same JVM) using the embedded driver in
combination with allowing remote access on the same database? I'm having
some issues getting it to function, seems like it's one or the other.
perfect, thanks!

My primary use case is to use an embedded derby within my webapp for
storage and whatnot. I also have another requirement to provide localhost
(and possible remote access) to the database via jdbc connection. I know
how to get derby up and running programmatically in embedded mode and with
the netw
tweaks, i was unable to work around it.

Greetings. I'm looking for some kind of migration guide and for things to
watch out for when migration an application to derby.
Since i haven't found one yet, i decide to write down and share some of my
notes on the things I've ran into so far:
DDL - From postgres, there's lots of differences.
