TRAFODION-38 First working TMUDFs in Java
Also addresses:
TRAFODION-7 Have a .project file to be able to import source code into
Eclipse
TRAFODION-35 Add a method that allows UDR writers to debug their UDRs on a
release build
Summary of changes:
TRAFODION-7:
Eclipse project files can now be generated with the following make target
in the core directory:
cd core
make eclipse
This will print out instructions on how to import the generated projects
into Eclipse.
TRAFODION-35:
Java UDRs are debugged with the following CQDs:
cqd UDR_JAVA_DEBUG_PORT
cqd UDR_JAVA_DEBUG_TIMEOUT
The best way to do this is with the sqlci tool. Set UDR_JAVA_DEBUG_PORT
before executing any Java UDR. Then, after executing the
first one, attach a remote Java debugger like jdb or Eclipse. To debug the
very first invocation, set UDR_JAVA_DEBUG_TIMEOUT to
a time in milliseconds and attach the debugger within that time.
This debugs only the runtime part of the UDR. To debug the compiler
interface, set this environment variable before starting
sqlci:
export JVM_DEBUG_PORT=12345
For both cases, here are two more things to know: First, this only works if
you are connected as the DB__ROOT user (running
sqlci without special options runs as DB__ROOT). Second, if you want to
debug parallel instances of UDRs, choose a multiple of
1000 for the port number. Trafdion with then add <process id> mod 1000 to
the port and put all the parallel instances into Java
debugging mode on these different ports.
TRAFODION-38:
Integrating Java code written by Suresh and Pavani with the engine code for
Java TMUDFs.
Addressing a few Java issues flagged by Eclipse.
Adding Java TMUDF tests to core/sql/regress/udr/TEST001.
