How to run Java 32, on SL5.5 x86_64??

How to add a Raid Firmware driver??

I can see the 4 SATA Disk, but the idea is work using the Raid from the Bios, and don't create a new Software RAID I think that use the RPM is more easy that the Disk Image, because the Server have not a 3,5 Disk Driver... and try to emulate a floppy disk, may be too much. I don't now if I need to put the RPM file in a pendrive, or a cdrom, but the idea is have a chance to install the Driver before install the System and make the partitions. The Server is an Supermicro, 16CPM AMD Opteron, 16Gb Ram, 6 NIC all Intel NPU, and no driver problem, an the support give an ftp like this, ftp://ftp.supermicro.com/driver/SATA/Adaptec_ICH9R/Linux/17718/ to downaload the Disk Image or RPM, whit the Drivers.

The chkconfig script part is easy, just look in /etc/rc.d/init.d, steal an existing service's script, and modify it to run what you want. Note the commented line at the top starting with chkconfig - that information specifies the run levels chkconfig will set it up to be activated in, and the startup/shutdown priority. As for the code you run, that gets trickier. All the startup scripts do is start and stop things. Those things could be more scripts, executables, or combinations thereof. Areas to pay attention to with your code (to get it to behave nicely when run this way) include: getting it daemonized properly (dropping and/or redirecting IO streams), privilege seperation (can it run as a non privleged user? if so, do that, if not, be really careful and have only the bare minimum code run with elevated privileges), logging (have it log status information, ideally with customizeable log levels, to the appropriate place), and signal handling so it shuts down cleanly when told to, reloads configuration files if asked, etc. There is also libdaemon which is meant to facilitate converting your program into a proper daemon (not tried it, though).

If you want to have more options, like search the more quickly mirror and another details, you need install the yum tools, and for use in the graphical environment, you can use the yum-ex, to find and install or remove a lot of .rpm in a single step, with all dependencies. Like example # yum search mysql to find the packages related with MySQL, like php, mysql client, server, etc. and #yum install mysql.i386 like example to install.

In fact it doesn't recognize -o cpi=12 or any other font size. This script takes the complete parts (thousands of parts) list and inventory and allows users to input a partnumber, or range of pn's and print labels from anywhere in parts list, awks the parts list and prints the labels at selected locations on a page of sticky labels. Completely formated to label page. Tests: Removed the -o cpi=10 from script and it runs fine except the font size is the default of 12. The output data was redirected to file junk If you cat junk | lpr -o other options -P ep900c it will print. Add -o cpi=10 and it halts no error message - nothing. Page is in CUPS as a sent file but no printing. The hardware, printserver, printer is unchanged but with the upgrade to SL 5.5 we can no longer print at a defined cpi. To test we tried several printers on the network and all have the same result. They work fine with out the -o cpi=10. The job shows it was processed by cups but never is deleted from jobs list. It like the font list was some how disconnected, lpr never times out after hours of letting it run. It has got be something that was changed or upgraded and defaults set or ??? Larry Linder
