Public Property DisplayGroupTree As Boolean’ is obsolete.

In this version Crystal Reports can have a parameter panel. I now have to tell crystal reports what will be displayed in the left panel:

• the group tree
• the parameter panel
• nothing

The parameter is ToolPanelView. If you don’t want to show nothing in the left panel:

rptViewer.ToolPanelView = CrystalDecisions.Windows.Forms.ToolPanelViewType.None

1. Disable bin logging
nano /etc/my.cnf
2. Comment all bin logging related lines

#log_bin = /var/log/mysql/mysql-bin.log
#expire_logs_days = 10
#max_binlog_size = 100M

3. Restart MySQL
4. Delete the bin log files by entering in mysql with:
mysql
5. Run the following command:
PURGE BINARY LOGS TO 'mysql-bin.03';

where 03 is the last number of the bin log you want to clear.

DIRNAME
-CHILD1
-CHILD2

DIRNAME> svn propset svn:ignore CHILD1 .


attention! You have to be inside DIRNAME.

--> Missing Dependency: perl(String::CRC32) is needed by package lftp-3.7.11-4.el5_5.3.x86_64 (base)
Error: Missing Dependency: perl-String-CRC32 is needed by package lftp-3.7.11-4.el5_5.3.x86_64 (base)
Error: Missing Dependency: perl(String::CRC32) is needed by package lftp-3.7.11-4.el5_5.3.x86_64 (base)


You just need to install the Perl module. To do this, login to SSH as root and type:

perl -e shell -MCPAN

If it asks you to set it up, just type “no” and it’ll use the defaults.

cpan> install String::CRC32
cpan> exit


2. Download the latest EPEL repository for x86_64
wget http://download.fedora.redhat.com/pub/epel/5/x86_64/epel-release-5-3.noarch.rpm

3. Run the rpm install command
rpm -Uvh epel-release-5*.rpm

If you want to change the priority of the repository edit this file :
/etc/yum.repos.d/epel.repo
And change this value :
priority=2

hdparm -tT /dev/sda1

A good test result is this one:
# hdparm -tT /dev/sda1

/dev/sda1:
Timing cached reads: 21416 MB in 1.99 seconds = 10785.03 MB/sec
Timing buffered disk reads: 106 MB in 3.01 seconds = 35.16 MB/sec


then create a .htpasswd file in /home/site-name/public_html/ with the following content:
user-name:faut1Lbo9LqK8NgU0

where “faut1Lbo9LqK8NgU0″ is the hash of the password. You can generate an has with this link: http://www.htaccesstools.com/htpasswd-generator/

mysql -u root -p -e "SHOW TABLES IN DATABASE-NAME;" | tail -n +2 | xargs -I '{}' echo "ALTER TABLE {} ENGINE=INNODB;" > alter_table.sql
and then run:
perl -p -i -e 's/(search_[a-z_]+ ENGINE=)INNODB/\1MYISAM/g' alter_table.sql

Replace “DATABASE-NAME” with your database name. You also need root access (preferably).

than …it’s complicated!

Most likely you have an outdated SAS 6iR Driver that is not compatible with the latest CENTOS kernel. You need to update the SAS 6iR driver.

To do this, you first need to use the ELRepo repository.

rpm –import http://elrepo.org/RPM-GPG-KEY-elrepo.org
rpm -Uvh http://elrepo.org/elrepo-release-5-2.el5.elrepo.noarch.rpm

Than go to /etc/yum.repos.d/ and put enabled=1 to all elrepo drivers.

Please check, as follows, for a base-line reference:

find /lib/modules -name mpt\*.ko | grep -E ‘extra|weak’
ls -l /etc/depmod.d/*.conf /etc/rc.d/init.d/mpt*

Both should have null returns.

yum install kmod-mptfusion

and then repeat the above two commands.

find /lib/modules -name mpt\*.ko | grep -E ‘extra|weak’
ls -l /etc/depmod.d/*.conf /etc/rc.d/init.d/mpt*

then run

chkconfig –list mptfusion_ctl

It should be “on” for runlevels 2, 3, 4 & 5.

Reboot and check the driver version. It should be 4.x.x
