garbage text in SHMNOACCESS parameter

Posted in 2010

Summary

brenddie found the SHMNOACCESS line in the onconfig of IDS 11.50.UC5WE on Linux held garbage characters instead of hex values, though the server ran normally. Ian Michael Gumby asked for the hex value of the string; brenddie replied with od and hexdump output. No explanation or fix was given.

While doing some changes to the onconfig file I noticed that the SHMNOACCESS parameter is set to what seems to be garbage text: RESIDENT 1 SHMBASE 0x44000000 SHMVIRTSIZE 1000000 SHMADD 524000 EXTSHMADD 8192 SHMTOTAL 0 SHMVIRT_ALLOCSEG 0.000000 SHMNOACCESS ^\\û·¿<96>ü·¿Øú·¿^V"^T^H^\\þ·¿ ú·¿ The server seems to be operating normally and I see no errors or warnings related to that parameter. Any idea how that got there? Docs say it should be hexadecimal values/rages.

Just a guess. What's the hex value for that string? > From: brenddie@gmail.com > Subject: garbage text in SHMNOACCESS parameter > Date: Wed, 20 Jan 2010 19:46:16 -0800 > To: informix-list@iiug.org > > While doing some changes to the onconfig file I noticed that the > SHMNOACCESS parameter is set to what seems to be garbage text: > > RESIDENT 1 > SHMBASE 0x44000000 > SHMVIRTSIZE 1000000 > SHMADD 524000 > EXTSHMADD 8192 > SHMTOTAL 0 > SHMVIRT_ALLOCSEG 0.000000 > SHMNOACCESS ^\\û·¿<96>ü·¿Øú·¿^V"^T^H^\\þ·¿ ú·¿> > The server seems to be operating normally and I see no errors or > warnings related to that parameter. > Any idea how that got there? > Docs say it should be hexadecimal values/rages. > > IBM Informix Dynamic Server Version 11.50.UC5WE -- On-Line -- Up > 00:09:04 -- 1684380 Kbytes > > Linux xxx.xxxxxx.com 2.6.18-120.el5PAE #1 SMP Fri Oct 17 18:17:11 EDT> 2008 i686 i686 i386 GNU/Linux > _______________________________________________ > Informix-list mailing list > Informix-list@iiug.org > http://www.iiug.org/mailman/listinfo/informix-list _________________________________________________________________ Hotmail: Powerful Free email with security by Microsoft. http://clk.atdmt.com/GBL/go/196390710/direct/01/
