In short, +here's what I did: + + - Put engine into ANSI SQL mode by using the following odbc.ini: + + [ODBC Data Sources] + test + + [test] + ServerDB=test + ServerNode= + SQLMode=3 + + - Grabbed the db_Oracle package and copied it to db_Adabas + - Implemented a 'version' method. + - Ran crash-me with the --restart option; it failed when guessing the + query_size. + - Reran crash-me 3 or 4 times until it succeeded. At some point it + justified its name; I had to restart the Adabas server in the + table name length test ... + - Finally crash-me succeeded. + +That's it, folks. The benchmarks have been running on my P90 machine, +32 MB RAM, with Red Hat Linux 5.0 (Kernel 2.0.33, glibc-2.0.7-6). +Mysql was version 3.21.30, Adabas was version 6.1.15.42 (the one from +the promotion CD of 1997). I was using X11 and Emacs while benchmarking. + +An interesting note: The mysql server had 4 processes, the three usual +ones and a process for serving me, each about 2 MB RAM, including a +shared memory segment of about 900K. Adabas had 10 processes running from +the start, each about 16-20 MB, including a shared segment of 1-5 MB. You +guess which one I prefer ... :-) + + +Jochen Wiedmann, joe@ispsoft.de |
