MySQL Perl DBI

Dear Wise & Powerful Masters of OS X,
I had written a large number of perl scripts that passed information back & forth to MySQL. Then my disk drive wore out & broke down`;'^(
What is the best way to restore the DBI(Data Base Interface)between MySQL & perl? So far I get:
$perl new.pl
install_driver(mysql) failed: Can't find 'bootDBD_mysql' symbol in /opt/local/lib/perl5/site_perl/5.8.8/darwin-2level/auto/DBD/mysql/mysql.bundle
at (eval 4) line 3
Compilation failed in require at (eval 4) line 3.
at new.pl line 143
$
Thank you for your kind wisdom.
Your humble unix geek,
Kurt

Ok - I am getting closer to resolving this issue. I downloaded MySQL server libraries from Apple, file and instructions are here: http://support.apple.com/kb/HT4006
After that, I was able to install Perl DBD::MySQL ver 4.013
Now machine sees it but a different error is thrown:
"install_driver(mysql) failed: DBD::MySQL object version 4.013 does not match bootstrap parameter 4.005 at /System/Library/Perl/5.10.0/darwin-thread-multi-2level/DynaLoader.pm line 230.
Compilation failed in require at (eval 3) line 3."
Now, there is a 4.005 version of DBD::MySQL but it is 3 years old. I am not sure if it is just a coincidence with a "4.005" index being similar to module version number, or this is indeed what system is requiring.
Any suggestions? Thanks in advance

Can't install Perl DBI or DBD::mysql after Mountain Lion upgrade

I recently upgraded to Mountain Lion and found that my Perl DBI scripts stopped working, with the error message "Can't locate DBD/mysql.pm in @INC".
The last time this happened, after upgrading to Lion, the solution was to install the new version of Xcode. Then I was able to use the Perl CPAN module to install DBI and DBD::mysql. (MySQL is already installed and running with no problem on the Mountain Lion machine.)
Now I have installed Xcode 4.5.1, and tried
mrb% sudo perl -MCPAN -e shell
[then CPAN configures itself]
cpan[1]> install DBI
and it fails with this final message:
/System/Library/Perl/5.12/darwin-thread-multi-2level/CORE/perl.h:583:11: fatal error:

Can anybody help?

Here is a link to a resolution in Lion. It may also solve your Mountain Lion Perl DBD issue as well.
If you run the command below before executing your Perl script the library is found and all is well!
export DYLD_LIBRARY_PATH="/usr/local/mysql/lib:$DYLD_LIBRARY_PATH"
Put this in your .bashrc or .bash_profile.
On Apple StackExchange, Matthew Weiss had another approach.
I found on another website the following command
$ sudo perl -MCPAN -e 'CPAN::Shell->notest(install => CPAN::Shell->r)'
This updated all my perl modules and all is back to normal. Not sure why or what, but don't care that it is working now.

SAMP perl dbi mysql

I have Solaris 10 0606 running with Apache2 mysql and php - all standard. I can access data on mysql thru a simple php script via Apache2. I would like to run a Perl cgi script to access the mysql database, but am having problems. It appears DBI.pm is not available. Does Solaris 10's 0606 full install support the ability to access mysql data via Perl DBI or other mechanism? If so, does anyone have a simple example of how this was done? If it is not supported, and additional Perl modules or other configurations are needed, does any one have a listing of steps to get this working? Thanks!

This is a bug report I filed with Blastwave.org after attempt to use their DBI::Mysql package.

And the bug report response:

This is not a bug in CSWpmdbi. All blastwave perl modules are built to use CSWperl. CSWpmdbi is also built to work with CSWmysql4.
I recommend that you use the blastwave packages and not the Sun supplied packages. Many sites use the blastwave packages and they can use any other blastwave package that needs perl and mysql. The same is true for perl and postgresql.
Or, if you believe that you must use the Sun supplied perl and mysql, you should be able to build and install DBI. You will need to download Studio 11. Studio 11 is available at no cost to you.

Oracle 8i equivalent of $sth- {mysql_insertid} w/Perl DBI?

What is the easiest way to obtain the value of an auto-incrementing column following an insert using Perl DBI with Oracle 8i? I've done it for years under MySQL using my($lastInsertID)=$sth->{mysql_insertid}, but that's obviously MySQL-specific (if only because of the name).

: 2 - can't use PERL in o/s because O/S is Linux
and clients cgi's
: use DBI:DBD:Oracle. There doesn't seem to be a
DBD for DBI for
: Oracle 8i for Linux. I have succeeded in
making our scripts talk
: to an Oracle 8.0.5 database, but get many
errors when connecting
: to 8.1.5 Does anybody out there have DBD for
DBI for 8.1.5 for
: linux RH 5.2 ????
DBD::Oracle should work just fine with 8.1.5.
What's so special about 8.1 vs 8.0? I beleive
OCI was not changed. Anyway, it works here. What
version did you try? Latest is 1.03, AFAIK. If
you have errors you probably should report them

How to install Perl DBI & DBD modules correctly?

PLEASE HELP!
I'm running OS X Snow Leopard 10.6.3 on a MacBook Pro.
Using MacPorts I've installed the following items:
mysql5 @5.1.45_0 (active)
mysql5-server @5.1.45_0 (active)
p5-dbd-mysql @4.013_0+mysql5 (active)
p5-dbi @1.609_0 (active)
perl5.10 @5.10.1_1+darwin (active)
Everything seems to be working, with the exception ofthe Perl DBI module, and the DBD module. Whenever I try to run a Perl program using DBI, I get the following error:
Sun Apr 18 03:18:42 EDT 2010

If anyone can also explain what @INC is (I'm assuming it's some kind of path), how to display its value, and how to set it correctly, I'd appreciate that too! I've been working on this for days, so I'd really be grateful for some help!
Thanks,
Peter V.

I've found the problem. I didn't realize that OS X Snow Leopard came with 2 versions of Perl installed, so when I wanted to upgrade to 5.10, I installed it using MacPorts. I also hadn't realized that MacPorts paths had /opt/local prepended to them, so I was running the wrong version of Perl with it. Now I don't get the original error message I posted, but I do get these error messages:
dyld: lazy symbol binding failed: Symbol not found: mysqlinit

MaxDB perl DBI and sql error -4008

I'm using PERL DBI module to connect to my liveCache instances, as a read-only user, to obtain status of various things.
I've installed the latest MaxDB DBI modules and latest MaxDB 7.7 Linux runtimes.
I can successfully connect to a livecache 7.4 instance, but for some reason when I connect to a 7.6 instance I get a DBI error:
sql error -4008
failed: POS(1) Unknown user name/password combination
My code is:
$dbMAXDB = DBI->connect("dbi:MaxDB:$o_nodename/$o_SID",$maxdb_usr,$maxdb_pwd, \%dbi_attr) or die;
The above code works with 7.5 etc, but not for my 1 single 7.6 instance!
The username/pwd is correct, as using dbmcli with the same username/pwd works.
Has anyone experienced this, or can someone offer a solution?

Maybe you use the administrator user instead of the SQL user? MaxDB distinguishes between Administrators - as we called them - and SQL users. The group of Administrators (Database Manager operators, DBM operators) is used for the administration of the database only (start, stop, backup etc.) and cannot be used to open a SQL session. So please make sure that the user is a SQL user.
Also you might check if you will be able to connect to the database with the command line tool sqlcli using this user.
Regards,
Marco

Perl DBI and DBD

I know there has been a thread for this but there does not to be an answer to this.
I have a new mac mini with Snow Leopard which I installed MYSQL 5 64 bit. I am trying to run perl scripts that connect to MYSQL but Perl throws an error regarding the DBD module. I have tried using CPAN to update the modules which seems to be successfull in regards updating but still I get the DBD module error. I have tried installing the modules manually but still I get the same error. Also I tried 32 bit MySQL but still it does not work.
Has anyone solved this problem at all? I have rolled back my Mac using timemachine to the stock build so I am ready to try this all again!
Regards
Chris.

Unfortunately, you are going to have to find out. You are trying to get 4 very complex systems (MacOS X, MySQL, Perl, and CPAN) all working together. Plus, you have chosen to do so on a brand-new OS.
If you want people to be able to help you can't just say things like "an error", "does not work", or "a web site". You must be explicit. What error are you getting? Use copy and paste. If you try it a different way, what error is that? What web site were you looking at? Maybe it was from 2002.
Your first step is to find out just what is installed on your system. Use the command "file" to find out what architecture your mysqlclient libraries are. Also find out about your DBD files.

Solaris 10 sparc + mysql + perl + dbd mysql + apache2

Is there any sane way to build dbd 4.013 mysql on a clean solaris box with sunstudio installed?
I want to use the mysql that comes with solaris 10.
I want to use the perl installation that comes with solaris 10.
I have been trying to build it for days on u8 sparc. Everything else works. Heck, I even got imagemagick and perlmagick to build correctly.
CPAN does not work for DBD
cc does not work.
I assume this has to do with the version of mysql that comes 'preinstalled' in solaris 10.
Any suggestions?

Nothing at all. In fact I have never ever had a problem with sunstudio. It boggles the mind that they put those SUNWgcc packages on a Solaris release but not sunstudio. It is such a great bit of software.
I have now found the only way to really get around this is to build mysql from scratch and then build dbd. It worked perfectly just now. I could not get DBD to build with any of the packaged version of mysql. This makes updating difficult but I can get around that.
Now my stupid perlmagick is busted though. arrggghhh....

'TNS: no listener' usually means that your listener hasn't been started. Try a lsnrctl status to find out whether your Listener is actually running.

Perl DBI and ODBC Access to Oracle

I am trying to communicate with an Oracle database from a Debian Linux system.
I have looked through much documentation of various vintages, on how to achieve this, but I am still unclear about what I need.
I have the iODBC stuff, but this seems to need a "driver". Most references to drivers seem to need something from the Oracle distribution - typically header files or "oracle.mk"
Can anyone point me to an open source or downloadable driver, or help me to identify a way of downloading the necessary bits of Oracle to permit a driver to be built.
Thanks, (in hope),
Dave Whiteley

Re the reply below,
<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by gv ():
you need two things:
the DBI package (interface)
the DBD package (driver)
you can find both on CPAN
<HR></BLOCKQUOTE>
Things are not as simple as indicated. To install the DBD package you MUST have an environmental variable ORACLE_HOME set up and pointing at an Oracle installation. It reads some of the files there in order to install itself.
This means that to install DBD:Oracle you need to first install Oracle... Unless, someone knows which files are necessary for the install, and they are legally availablke without breaking the Oracle license.
I have sucessfully installed DBD:Oracle in this way (at least, I can communicate with a remote server).
There are similar issues with DBD:ODBC.
This installs easily, however, as I understand the situation, it needs to communicate with other local "driver" software in order to contact the remote server. I I have not yet sucessfully installed and used this "driver" software. Again this seems to require a lcal Oracle installation.
The driver software consists of a driver manager, and the driver itself. Different people distribute different versions of these and the documentation available has confused me - perhaps some of it is out of date?
Up to now I am working on a lightly loaded machine with space. I will need to set up the working system on another more heavily loaded machine. I do not want to have to Install Oracle on that. I will never use it. It will only be there to permit installation of the Perl DBD stuff.
Hints and advice welcome.
Dave

MySQL doesn't start[solved]

I can't get the MySQL server to start.
I have followed the wiki entry and fixed all the permissions and the ownership.
Here is the error log

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help diagnose
the problem, but since we have already crashed, something is definitely wrong
and this may fail.
key_buffer_size=16777216
read_buffer_size=262144
max_used_connections=0
max_threads=151
thread_count=0
connection_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 134067 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h lovelock password 'new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl
Please report any problems with the /usr/scripts/mysqlbug script!
