This is my memo for quick reference to install SAP Java Connector 3(SAP Jco3) on tomcat in linux system.
I use RHEL5,tomcat6,sapjco3. Here are simple step.
1. Check your java version, SAP Jco3 require JRE 1.5 or 1.6
2. Download latest SAP Java Connector from http://service.sap.com/connectors select package that match your hardware. In my case,package for linux on intel x86 is sapjco3-linuxx86_64-x.x.x.tgz
3. extract file to sapjco-installation-path like /opt/sapjco3
4. add your sapjco-installation-path to environment variable LD_LIBRARY_PATH.
5. add your sapjco-installation-path/sapjco3.jar to environment variable CLASSPATH.
restart tomcat. That's it.
If you migrate from sapjco2 to sapjco3 you have to adapt your code by read this migration guide:
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/6080c13b-e2d1-2c10-5f88-bd5a9e35d726?QuickLink=index&overridelayout=true
After add new SAN disk to linux system, if you want linux system detect new disk without rebooting system you can execute this command.
for scsi disk
#echo 1 > /sys/class/fc_host/host$host/issue_lip
for fc disk
#echo "- - -" > /sys/class/scsi_host/host$host/scan
you can list your hba wwn in linux by display node_name
#cat /sys/class/fc_host/host$host/node_name
while $host is your hba no.
you can display scsi device in linux system by display scsi that will map to device like /dev/sda, /dev/sdb in sequence.
#cat /proc/scsi/scsi
for example: it will map scsi0 to /dev/sda and scsi1 to /dev/sdb
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: ATA Model: ST3320620NS Rev: 3.AE
Type: Direct-Access ANSI SCSI revision: 05
Host: scsi1 Channel: 00 Id: 00 Lun: 00
Vendor: ATA Model: ST31000333AS Rev: CC1H
Type: Direct-Access ANSI SCSI revision: 05
to remove single scsi device:
echo "scsi remove-single-device a b c d" > /proc/scsi/scsi
to add single scsi device:
echo "scsi add-single-device a b c d" > /proc/scsi/scsi
while
a == hostadapter id (first one being 0)
b == SCSI channel on hostadapter (first one being 0)
c == ID
d == LUN (first one being 0)
Because xen virtualization will be replace by kvm on rhel6 so I have to migrate my server that running on xen virtual machine to kvm. after search on internet that have many documents and method to convert xen guest to kvm, I test migrate by manual method which is working well and easy to migrate.
My environment, I am running rhel5 xen kernel 2.6.18-92 guest and migrate to host running on the rhel5 kernel 2.6.18-168
Here are steps to migrate to kvm virtualization
1. comment HWADDR line on /etc/sysconfig/network-scripts/ifcfg-
2. change xvc0 to ttyS0 (if exist) in /etc/inittab, /etc/securetty, /boot/grub/grub.conf
3. change /dev/xvda (xvdb etc..) to /dev/hda (in case no virtio drivers or /dev/vda with virtio) in /boot/grub/device.map, /etc/fstab
if you map device with partition label (LABEL=SWAP-sda2 /swap in fstab for example) you can change partition lable with command "e2label
For change upload limit for php, you have to change upload_max_filesize, memory_limit and post_max_size parameters in php.ini (/etc/php.ini - linux) then restart apache server (service httpd restart).
someone said that post_max_size and memory_limit need to be larger than upload_max_filesize.
Today i testing moodle on my server and try to upload video file about 200MB.
For change upload file size i have to change upload_max_filesize and post_max_size on php.ini.
After that I try to upload avi file and get error and cant login to moodle anymore so i think it has something wrong about session.
after searching ppl say that have to change dbsession in mdl_config table so i try to change it in mysql database but i get error "You probably tried to upload too large file. Please refer to documentation for ways to workaround this limit."
The reason of error is i wrong config in php.ini that i should change 3 parameters upload_max_filesize, post_max_size and memory_limit , so when i change all of parameters my moodle system working fine.
Today I will test buddypress on WP 3.0 so I install new WP and buddypress on my localhost testing system, after finish install i get HTTP ERROR 404 NOT FOUND so I searching for the solution.
In my case, fix it by:
change http.conf to use mod rewrite by uncomment line
#LoadModule rewrite_module modules/mod_rewrite.so
then change "AllowOverride None" to "AllowOverride All"
# AllowOverride controls what directives may be placed in .htaccess files.
# It can be "All", "None", or any combination of the keywords:
# Options FileInfo AuthConfig Limit
#
AllowOverride All
after change apache config you have to restart apache.. done
another reason that may happen is wordpress can't write .htaccess in wordpress directory when you change permalink in wordpress setting
solution is change .htaccess file permission from 644 to 666 then change permalink setting from wordpress dashboard, after that change file permission back to 644.
wordpress will write new access rule to .htaccess according to your setting correctly

edit the file wp-includes/pluggable.php
in line 863 replace:
if ( $is_IIS ) {
header("Refresh: 0;url=$location");
} else {
if ( php_sapi_name() != 'cgi-fcgi' )
status_header($status); // This causes problems on IIS and some FastCGI setups
header("Location: $location", true, $status);
}
with this:
if( !headers_sent() ).
{
if ( $is_IIS ) {
header("Refresh: 0;url=$location");
} else {
