Mysql instance

I have somehow locked myself out of being able to connect to
the mysql 5 server using mysql administrator.
Error: Could not connect to MySql instance at localhost.
Error: Access denied for user 'root'@localhost
I tried Navicat and that also does not let me connect or
delete or anything.
Error: Host 'localhost' is not allowed to connect to this
mysql server.
Is this something with permissions? I was using the terminal
so I may have screwed something up. How do I get the permissions or
whatever back so I can get connect with the mysql administrator?

Connect "Generic Data Source" target to a MySQL instance

I'm trying to connect our TEO (2.2) instance to a MySQL instance, but unable to do so successfully.
On the TEO server, I've loaded the MySQL provider as well as the ODBC driver.
I then try to define the connection details in the new target:
Hostname: <hostname of the server hosting MySQL>
Default user: <runtime user for the read-only account to the database>
Connection String: Provider=MySQLProv;Data Source=<database name>
Clicking "OK" throws the following error: "The 'MySQLProv' provider is not registered on the local machine."
Based on the error, it feels to me like the TEO server doesn't recognize that provider, but I'd like some help on getting it to the point where it does.
Could you please provide me with the steps needed to get our TEO instance to connect to the DB?
Thanks,
Mark
Solution:
1) Install the provider from Cherry City Software : http://cherrycitysoftware.com/CCS/Providers/ProvMySQL.aspx
2) Configure the connection string as follows: Provider=OleMySql.MySqlSource.1;Data Source=<FQDN of DB host>;Initial Catalog=<DB name>
Thank you very much C Roberts!

The connection string shows "MySQLProv", is that what you actually used?
Looking at the sample C# code(and VB.net) I see this as the provider:
OleMySql.MySqlSource.1
Did you try that?
Also it looks like
Data Source=
Initial Catalog=
If you cannot get by this, would probably be best to open a TAC case for review.

MySQL Instance Metrics not getting collected in OEM 12c

Hi All,
For MySQL instance, we have enabled "Other Statistics" metric collection and the collection time is every 15 mins.
We have not set any thresholds so this is not for alerting purpose.
For reference if I consider mysql_s_cpcwcmsqlq02e, I checked in backend the scheduler status and found below output in which I am not able to see other statistics metric for mysql:

Mysql on macbook

hello, i have a macbook running mac os x, version 10.6.1. I have apached setup and
am running php as well. I recently downloaded and installed mysql and mysql gui tools.
I tried to connect to mysql via mysql administrator and got the following error:
connection error
could not connect to mysql instance at localhost
error can't connect to local mysql server through socket 'tmp/mysql.sock'(2) (code2002)
I'm a developer and have picked up a mac to begin coding on the mac. I have a VAMP running and
it works great; just want to figure out how to get mysql running on the mac.
thanks

HI,
Im having a similar problem.
However, here are some things I've discovered. If you go to the directory that you're pointing at, there's nothing there.
If you've downloaded and installed the 5.1.x version from MySQL site, then you're probably having the same problem I'm having....PHP sees the 5.0.51 version but not the correct version that you've installed.
Are you running the proper 64bit version or 32 ? It makes a difference. Im running 64 and I can't get PHP to connect.
Further the MySQL admin is a piece of crap! Always has been on the mac. Get Navicat. You'll be happier. You can at least connect to your databases. PHP is a whole other story.
Still another little detail is the date.timezone bug that's now present. Find this line in your PHP.INI file:
;date.timezone =
and uncomment it. Then add your time zone location. http://php.net/manual/en/timezones.php
Hope that helps....

MySQL performance on Windows

Hi all.
I have been using LV2010SP1 with MySQL to implement data acquisition systems for hundreds of channels. I typically run the MySQL instance on the same machine as the LV app and I love the synergy this combo provides. I interface LV with the database using Mike Porter's excellent ADO database toolkit. (I can't find a link to it presently but I found it on the forums.)
I have a LV process to collect the data into a table. I have another LV process to mine a small subset of channels for plotting on a chart.
I have run into a few limitations with my implementation. When the number of records in the table grew to >250K, the process of querying the table began to grow large. I now see query times longer than 50 seconds while I'm trying to refresh the chart every 10 seconds. This obviously won't work.
The current machine I am using is a Toshiba Satellite with a quad core i3, 4GB RAM, 500GB HDD, and Windows 7. When I examine the task manager in Windows, it shows most of the processor time spent idle. When I look at the MySQL Workbench performance charts, they seem to indicate a low level of activity. I'm not sure what to do to boost the performance of this setup. Have any of you expeienced similar problems?
Thanks.

I use sqlite (with a LV interface I wrote) so if the problem isn't related to some quirk with mysql, I might be able to point you in the right direction.
Is the query slow when you don't have the collection process running? (maybe some kind of contention between the reader and writer).
Is it still slow if you break the query up into smaller queries? (I'm not sure what the ADO toolkit offers but limit and offset should work although they probably aren't the ideal method, this might indicate some memory handling issues)
Are you sure that the query is the slow part, and not display code or something else? (easiest to check by just running the query by itself, be sure to try combining this with breaking up the query)
What does the slow query and database schema look like? (maybe you need to add an index or adjust the table structures)
Does it become gradually slower or suddenly jump from fast to slow?

Setting up MySQL in Netbeans IDE7

hello
I am situated at MySQL Server Properties dialog box at the Administration Properties tab in Netbeans IDE 7. In this dialog box there are 3 tabs needed to fill in to successfully set up SQL server. These tabs are:
Path/URL to Admin Tool
Path to start command
Path to stop command
In the dialog box under each tab there are other tabs called Arguments. I am not sure but perhaps for my particular services Arguments tabs may or may not be left empty.
Each tab has a browse option next to it. Clicking on browse I have the options to save on desktop, documents...... and so on.
With no luck clicking browse and saving the file. As a new comer to Netbeans what can I possibly do in this dialog box to create SQL server? Thank you.

Cannot log onto MySQL CMS Database after network installation

Post Author: matthewh
CA Forum: Authentication
I've just installed Crystal Server XI R2 on a brand new server running MySQL 5.0.45 but when the installation completes it says it can't log on to the CMS database. It's created the empty database and I have the db.opt file in there but nothing else - no tables or anything. I've re-run the installation and done a repair and Modify but with no change. The CMS user has full rights to the MySQL instance for now, so it shouldn't have been an issue. Is there a SQL script available I can run to build the initial db manually? Do I need to uninstall and go through it all again? took over 2 hours across the network and the server is in another part of the country.

Post Author: TAZ

Hi Matthew,
I'm not sure why you cannot access your mysql DB but you do not have to reinstall.
Launch the CCM(central configuration manager) If the CMS is not stopped then stop it.
double-click on the CMS choose configuration, choose specify, choose recreate the current data source.
This will reinitialize the CMS DB if the account configured has the proper permissions. It should be a DB owner

Does ODI work with MySQL?

I'm trying to install this on linux and I'd like to install my repositories in MySQL (my server version is 5.0.41).
Despite there being no mention of MySQL in the documentation, I had read somewhere (?) that this is possible and when I looked in the oracledi/lib/scripts directory there's definitely a directory called MYSQL (hopeful)
I've set all the web stuff up under tomcat and the diwld seems quite happy to connect to the MySQL instance as does the master repository wizard but now I'm stuck as I don't know what 'Technology' option to choose to execute the create SQL statements.
Many thanks
Ceara

Hi Ceara,
Last I heard the repository is not supported in MySQL. This is due to some subquery feature that is not ANSI92 compliant.
Metalink Note 468131.1 has more details.

Mysql.sock - connection error (code 2002)

Performed a clean install of SL Server.
Enabled Web and MySQL services.
When using GUI (SequelPro of MySQL GUI Tools) I get a mysql.sock connection error.
"Could not connect to MySQL instance at localhost. Error: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) (code 2002)"
The database location of MySQL is /var/mysql. Thus a reference to /tmp/mysql.sock is obviously wrong.
The file /var/mysql/mysql.sock does exist but apparently no reference is made to this file.
Q: How to make a reference to the correct socket file,
Coen

It looks looks like the Sequel Pro app is guessing incorrectly that the mysql.sock is in /tmp. If that's the problem, you should be able to fix it by going to Sequel Pro's Connection panel and entering the correct path, which is /var/mysql/mysql.sock.

VDI 3.1 Big Endian vs Little Endian: VDI Cluster to Remote mysql server

Hello,
We are implementing a Dual Data center VDI environment and with that, will be using VCS to Cluster a remote Mysql instance. My question, if the VDI Cluster is on x86 (Little Endian), can the remote Mysql DB be on Sparc (Big Endian)?
Thanks,

The endian matching is only a requirement for the management and data nodes of a MySQL cluster. If you are going to be using a remote MySQL DB, the VDI servers will be connecting to that remote MySQL DB as a client connection, and there is no requirement for clients to match the endian type.

GoldenGate and Required MySQL Privileges

Hi,
Environment Details:
MySQL Version 5.1.56-log
GoldenGate Version 11.2.1.0.1
Issue:
We are replicating data from a MySQL instance containing two databases, db1 and db2. However, we are only replicating tables from db1. GoldenGate logs into the database using the user ggc which has the following MySQL grants:
GRANT USAGE ON *.* TO 'ggc'@'localhost'
GRANT SELECT ON `db1`.* TO 'ggc'@'localhost'
The extract parameter file is as follows:
EXTRACT E_LD_C
SETENV (NLS_LANG = "AMERICAN_AMERICA.AL32UTF8")
SOURCEDB ggc, USERID ggc
EXTTRAIL ./dirdat/E_LD_oc/oc
TRANLOGOPTIONS ALTLOGDEST /mysql/mysqllog/mysqlbin.index
TABLE db1.*;
After starting the extract it abends with the following message:
2013-03-19 17:58:34 ERROR OGG-00146 VAM function VAMRead returned unexpected result: error 600 - VAM Client Report <CAUSE OF FAILURE : Failed to Query Metadata for Table : db1.test_tab AND Failed Queries Are: QUERY_FAILED_CHARSET_RETRIEVAL,QUERY_FAILED_SIGNED_INFO_RETRIEVAL,
Looking at the MySQL query log one of these queries is:
select character_set_name from information_schema.columns where table_schema='db2' and table_name='other_tab' and ordinal_position=7
I suspect that GoldenGate is querying for metadata for tables it is not even replicating i.e., tables from db2, when encountering them in the binary log. Granting the following privilege resolves the issue:
GRANT SELECT ON *.* TO 'ggc'@'localhost';
However, for security reasons we only want to grant user ggc privileges to db1 not all the tables within the instance.
Any help with the following issue would gratefully received.
Thanks, Paul

My understaning is that you can't grant access to the INFORMATION_SCHEMA directly. If you grant access to a user for a table then that user can query the entries for that table in the INFORMATION_SCHEMA database. Therefore if GoldenGate is trying to access data in the INFORMATION_SCHEMA database for a table that it has no access to then it will retrieve no rows. This means that if GoldenGate is querying the INFORMATION_SCHEMA database for every table that writes to the binary log it will fallover when it encounters a table it does not have SELECT access to which to me means it must be given the privilege SELECT ANY TABLE to work.
Thanks, Paul

How to check the number of connections to MySQL DB

Hi,
Is there some way to check the number of applications connected to a mysql database?
I have two different Java applications that will be using the same instance of MySQL.
My requirement is that, I want to close the MySQL instance while closing the Java application.
But before doing so, I want to make sure the other application is not connected to it.
Is there some way I can achieve this?
Your suggestions will be of great help.
Thanks,
Sandeep

Hi,
Thanks for your response.
"Show processes" definitely serves my need.
Basically what I am trying to do is to check if there are any other open connections to a MySQL instance before closing it.
In our application suite, if there is a MySQL instance running, then the applications connect to it by default which results in some undesirable behavior sometimes.
Hence, we are making sure that we close the MySql instance before exiting the application.
Thanks,
Sandeep

MySQL - Oracle: files only?

Hi,
I have downloaded MySQL data files from Ensembl (http://www.ensembl.org/Download/) and like to load it into an Oracle database without starting a local MySQL instance.
Is it possible to read the MySQL data files and load it into an Oracle database?
Regards,
Andre

Andre,
The Oracle Migration Workbench works against a live mysql database (with running processes).
Oracle has a tool called sql*loader (sqlldr) for loading flat files into oracle, you would have to configure it and the oracle database depending on the data.
The alternative is to load the data into a mysql database and migrate the 'live' mysql database using the workbench.

How to Implement BW in IT Service Desk/IT Help Desk /IT Complain Surveillance Dept/IT Customer Support Dept?

Hi
If a organization have 200 to 300 daily complains of there IT equipment/Software/Network e.t.c.
How to Implement BW in IT Service Desk/IT Help Desk /IT Complain Surveillance Dept/IT Customer Support Dept?
Is there any standard DataSources/InfoObjects/DSOs/InfoCubes etc. available in SAP BI Content?

Imran,
The point I think was to ensure that you knew exactly what was required. A customer service desk can have many interpretations from a BI perspective.
You could have :
1. Operational reports - calls attended per shift , Average number of calls per person , Seasonality in the calls coming in etc
2. Analytic views - Utilization of resources , Average call time and trending , customer satisfaction , average wait time
3. Strategic - Call volumes corresponding to campaigns etc , Employee churn and related call times
Based on these you would then have to construct your models which would be populated by data from the MySQL instance for you to report.
Else if you have BWA you could have data discovery instead or if you have HANA - you could do even more and if you have a HANA sidecar - you technically dont need BW. The possibilities are virtually endless - it depends on how you want to drive it and how the end user ( client ) sees value in the same.
