RE: IDS 9.20.UC4 Error Message
Posted in 2000
Starts from a spurious "Error Writing 'Universal Server Message Log' errno = 0" after upgrading from IDS 7.3 to 9.20.UC4; it's confirmed as a bogus/cosmetic message Informix planned to fix in 9.3x (permissions on online.log were also suggested as a check). The thread then turns into a warning about 9.20 on AIX 4.3.2: poor performance under load, varchar-related crashes (fixed in UC4X1) and bad tempdb page headers, leading one poster to roll back to 7.31.UC7. Another saw slowdowns only after upgrading ESQL/C and 4GL (7.30.UC4), with the case still open at Informix, plus a complaint that GL_DATETIME overrides per-variable datetime qualifiers. No resolution is recorded for the performance or GL_DATETIME issues.

Are these issues concerning for AIX particular or for 9.2 in general???

The performance issues are generic to 9.20, it is the reason they are holding up 9.3. The rest may very well be problems with the AIX port.

I'm running a commerce web site and require stability and performance through the Christmas period. Besides, 9.21 was never ported to AIX.

We have the very same problems, especially on mass-selects, but they didn't start *until we installed the new ESQL/4GL*. When we only upgraded the engine there were no problem (of a performance nature, some of the other changes meant we had to do some tweaks). The case is currently at Informix for evaluation in a testcase. What irritates me more is the way GL_DATETIME overrides the <from> and <to> tags on CURRENT, making GL_DATETIME totally useless, well I'll properly have to get used to have the year in front even though it is vary unDanish. //FETheodorsen Finn E.

Which version of 4gl did you go to 7..??.??? 7.30.UC4 is the latest and should be the most stable. Finn E.

About the GL_DATETIME bug Err?? Can you give me an example?? > >Finn E. Theodorsen///finn@theodorsen.org///AtCbM///Legend#60219605 >J-M-B Type: INTP.

Current hour to minute gives the full year etc. as given in the GL_DATETIME etc. If GL_DATETIME isnt defined the standard format is used where no other is given, but any use of <variable> hour to minute etc. functions as it should. But as soon as GL_DATETIME is defined it is used everywhere, even when you try just to use a limited scope of fields. Try eg. define a datetime hour to minute b char(20) let a = current hour to minute display a let b = a display b let b = current year to year display b both with and wothout a GL_DATETIME //Finn Finn E.
