UDF compilation
by Miguel Ping 21 Dec '12

21 Dec '12

What are the steps required to include additional .c and .h files in compiling user-defined functions? It was a long time since I used autotools and such; it seems to me that I would need to change the monetdb configuration files in order to regenerate the Makefile.* files within the UDF dir. My problem is that I require alot of code for my UDF, and right now I'm copy/paste'ing code to udf.c and udf.h; it would be easier to include additional .h and .c files for UDF compilation. Thanks _______________________________________________ users-list mailing list users-list(a)monetdb.org http://mail.monetdb.org/mailman/listinfo/users-list

Announcement: New Oct2012-SP2 Bugfix release of MonetDB suite
by Sjoerd Mullender 21 Dec '12

21 Dec '12

The MonetDB team at CWI/MonetDB BV is pleased to announce the Oct2012-SP2 bugfix release of the MonetDB suite of programs. More information about MonetDB can be found on our website at <http://www.monetdb.org/>. For details on this release, please see the release notes at <http://www.monetdb.org/Downloads/ReleaseNotes>. As usual, the download location is <http://dev.monetdb.org/downloads/>. Oct 2012-SP2 bugfix release SQL * Fixed crash when performing an INSERT on a table with string-like column defaulting to NULL and omitting that column from VALUES, bug #3168 Java Module * Implemented type map support of Connection to allow custom mapping of UDTs to Java classes. By default the INET and URL UDTs are now mapped to nl.cwi.monetdb.jdbc.types.{INET,URL}. Most notably, ResultSet.getObject() and PreparedStatement.setObject() deal with the type map. * Fixed a problem in PreparedStatement where the prepared statement's ResultSetMetaData (on its columns to be produced) incorrectly threw exceptions about non existing columns. Bug #3192 Bug Fixes * 2291: small doubles end up as NULL after arithmetic * 2579: SQL: incorrect cast from double to int * 2659: tuples INTERSECT vs count (... INTERSECT ...) differs * 2805: row_number doesn't work in complex query * 2886: warning: Catalog parameter '' ignored * 2977: timestamp minus date results in program error * 2978: now() + 1 results in illegal argument * 2999: Up-cast from SQL drops order information? * 3048: algebra.join undefined when using multiple arithmetic operations in SQL where-clause * 3124: insert into table with two foreign keys crashes mserver5 * 3136: Memleak (in querycache?) while querying * 3143: Type resolution error in SQL procedural code * 3163: mserver5 crashes with large number of concurrent clients * 3168: crash when insert varchar/char/clob with default NULL * 3169: php driver uses call-time pass-by-reference * 3173: SQL queries with limit and offset clauses are unable to use bind parameters for either * 3181: Join query returns zero results when there is an index on the tables * 3185: inconsistency between documentation and implementation of command line options * 3186: case evaluted to early * 3188: Storage of client history * 3189: Overflow in calculation * 3190: When subtracting two columns of type "timestamp", no results are returned * 3191: rel_optimizer.c:5596: _rel_optimizer: Assertion `0' failed. * 3192: "No such column with index" error if CASE in SELECT clause * 3199: Inconspicuous sequence of prepare, execute, commit and close produces error * 3205: Inet datatype handling inconsistent between int, cast( as inet) and string _______________________________________________ users-list mailing list users-list(a)monetdb.org http://mail.monetdb.org/mailman/listinfo/users-list

OLTP Benchmark on Monetdb
by Hassan, Ahmad 19 Dec '12

19 Dec '12

Hi Team, I am trying to run TPC-C benchmark provided by opensource oltpbenchmark (http://oltpbenchmark.com) on MonetDB. But I am getting JDBC Exception while loading the data set: java.sql.BatchUpdateException: Error(s) occurred while executing the batch, see next SQLExceptions for details at nl.cwi.monetdb.jdbc.MonetStatement.executeBatch(MonetStatement.java:209) Exception in thread "main" java.lang.ArithmeticException: / by zero at com.oltpbenchmark.benchmarks.tpcc.TPCCLoader.load(TPCCLoader.java:1857) Please can you let me know any TPC-C benchmark implementation that is compatible with monetdb? Thanks. Kind Regards, Ahmad _______________________________________________ users-list mailing list users-list(a)monetdb.org http://mail.monetdb.org/mailman/listinfo/users-list

MonetDB compiling with CLANG/LLVM
by Hassan, Ahmad 18 Dec '12

18 Dec '12

Hi, I want to ask if someone has tried compiling MonetDB with Clang/LLVM compiler? I intend to compile MonetDB with LLVM for analysing the query execution at runtime. Does someone know the changes in the build process required for building Monetdb with clang/llvm? Thanks. Cheers, Ahmad _______________________________________________ users-list mailing list users-list(a)monetdb.org http://mail.monetdb.org/mailman/listinfo/users-list

Unable to execute prepared statements with a large number of parameters (say over 140 or so)
by Percy Wegmann 14 Dec '12

14 Dec '12

I couldn't find any existing bugs that cover this, so I logged a new one: http://bugs.monetdb.org/show_bug.cgi?id=3208 This is kind of a show-stopper for me right now, so I'm hoping that someone might have some idea where to start looking for a solution. I'm debugging sql_scenario.c right now, but it'll take me some time to get familiar with the code.

Still searching to find the Octopus :-)
by Masood Mortazavi 13 Dec '12

13 Dec '12

I'm still searching for user documentation that would explain MonetDB/octopus usage/feature. Does any exist? Thanks, Masood P.S. My earlier e-mails regarding the octopus documentation was somewhat rushed, it seems. The documentation in the man pages are actually for remtoe access and funnel-multiplex features, which seem entirely different. _______________________________________________ users-list mailing list users-list(a)monetdb.org http://mail.monetdb.org/mailman/listinfo/users-list

Re: Failed to load 128GB CSV file using Oct2012
by Stefan Manegold 05 Dec '12

05 Dec '12

Jennie, just to be sure: are you sure there is sufficient free disk space on your machine, say, twice the expected database size before starting the load? How large is your database (and sql_logs) just after the failure while the server is still running? How much disk space is still free at that time? Stefan Ying Zhang <Y.Zhang(a)cwi.nl> wrote: Hai all, I try to load a CVS file of ~128GB in the ssdb branch (based on Oct2012), but after quite sometime, it failed with: #GDKrealloc(19598973840) fails, try to free up space [memory in use=22695528216,virtual memory in use=138875848472] #GDKrealloc(19598973840) result [mem=22695528216,vm=138875848472] In the last Sep., I was able to execute the same query with the same data. But now it takes much longer and ends in a crash. For INS1-ers, the command to start the server: /export/scratch2/zhang/monet-install/ssdb/debug/bin/mserver5 --set gdk_dbfarm=/export/scratch2/zhang/dbfarm --dbname=ssdb --set mapi_usock=/export/scratch2/zhang/dbfarm/ssdb/.mapi.sock --set monet_vault_key=/export/scratch2/zhang/dbfarm/ssdb/.vaultkey --set gdk_nr_threads=8 --set max_clients=64 --set sql_optimizer=default_pipe --set mapi_port=60000 The command to start the query: cd /ufs/zhang/papers/ssdb/monetdb ./run.sh loadimg small output Does anyone have an idea? If anymore information is needed, please let me know. I'm re-running the query to get a GDB stack trace. Thanks!
