But if it does crash, ... I hope from the bottom of my heart that AOL 3.x won't crash because I want to use it as an application server for a 24 hours/day, 7 days/week and 366 days/year application!!!! So, please, give me an advice is I should continue using AOL 3.x for that application or I should abandon it and try other variants as EJB servers (JBoss for example). My application should monitor a PostgreSQL database, maintain a big memory cache in nsv_variables, interfere with client application written also in Tcl/Tk and communicating with server through HTTP requests, deal with a big number of readwrite locks, semaphores, events, SQL transactions and so on. Right now, just for scanning the database and build the memory caches, locks , ...., it takes 5 minutes on a Athlon 1.2 GHz, 256 Mb RAM. The final server will be a dual Pentium 1 GHz, 1 Gb of RAM, Cheetah 15000 rpm SCSI drives ... If AOL 3.x server will crash unexpectedly, I'm a dead person :-) , no kidding! I choose AOL because I love Tcl, I have read a lot about AOL server performances and I said : "If it's good for America On Line then it probably will be good for me". I don't want to spend thousands of dollars on a Bea Weblogic/Oracle or a Websphere/DB2 solution but I want to be sure that if my Tcl programs does not contain errors, AOL server will be up day & night from now on. I'm at the beginning of that big project and I don't want to spend months in writing an application that won't be reliable. (hardly) waiting for advice from AOL server gurus ...
