FAQ:NewInstanceMsSql Windows

Generalties

In this chapter, we will consider that SQWareCentral has been installed on dbsqware@sqwarebox.

Limits of this section

This chapter only deals with adding a new instance to a base that is already configured and functional.
Use the portions that apply to your environment, and choose either the automatic or manual method as desired

General operating procedure for integrating a new Sql-Server instance

There is only the case of remote connection to handle. We make an SQL connection from mssql@sqwarebox via FreeTds (OpenSource TDS connection client).

Classic steps:

• Setting up the environment

• Manual tests

• Deployment of the instance

You will see that these steps can be handled one by one or in batches!

Integration of an SQL-server instance

Setting up the environment

General

Explanation of "DbAlias" (the unique dbSQWare key)

The dbSQWare key must be unique and must match the entry configured in the freetds.conf file to connect to the instance. Generally, when there is no named instance, we use the name of the Windows host that holds the instance. When there is a named instance, we concatenate the name of the Windows host and the instance name, separated by an underscore (do not use a backslash, we are on Linux!)."
Examples :

• WINMSQ => WINMSQ (status ON)
• WINMSQ\INST1 => WINMSQ_INST1 (status ON)

Explanation of statuses

Classically, for SQL Server, the status is 'ON'
The 'OFF' status makes the instance disappear from the web view.
The 'NEW' status is used as an intermediate status between the beginning and the end of setting up a new instance.
All other statuses allow the instance to be displayed in the repository (especially 'KEEP'), but they will not be taken into account by the automatic processes."

Resume of statuses :

Status	Description
ON	locale under Unix (the most common)
KEEP	temporary status, during maintenance for example or before complete deletion
NEW	temporary status, during configuration
OFF	visual removal of the instance (without deleting its configuration)
XXX	not supported...

Instance declaration in SQWareRepository with SQWareWeb

We will declare the new instance from the SQWareWeb administration interface.

Declare the new instance with the status "NEW" (Add or Duplicate).


Explanation of the fields :

Fields	Description
Db Alias	Unique key that identifies the instance in dbSQWare (no value for MySQL/MariaDB).
Dbms Name	Type of SGBD
Virtual Host	Virtual Host (same as Host if not clustered) .
Host Name	Hostname of the instance
User Name	User associated with the instance
Port	Listening port of the instance.
Comments	A brief description of what the instance hosts
Status	Instance status (see above for explanations).
Contact	A contact if needed
Environnement	Instance environment (PRD, PPR, REC, DEV, TST, ...)
Client	Used only for filtering (enter a client name and/or department and/or service...)
GlobalHost	Free field in which the hypervisor host is often entered, for example.
Custom1	Free field 1
Custom2	Free field 2

Regenerate the reference files of SQWareCentral.

Type the following command which will generate the reference files:

1 # From : dbsqware@sqwarebox
2 gen_all

Creating a Specific SQL-SERVER Account (dbSQWare)

Example for a "Remote" Connection

1 grant all privileges on *.* to 'DBSDBA'@'%' IDENTIFIED BY 'DoNotSetThisPassword!' with grant option;
2 
3 /* or */
4 create user 'DBSDBA'@'%' IDENTIFIED BY 'DoNotSetThisPassword!';
5 grant all privileges on *.* to 'DBSDBA'@'%' with grant option;
6 flush privileges;

You can enter any username and password you like!
This account must be registered under the Unix account mysql@sqwarebox...

1  vi /home/mysql/.passwd_mysql
2  DbAlias;UserName;Passwd;HostName;Port
3  MYS_INST_PRD;DBSDBA;DoNotSetThisPassword!;srvdbmys01;3306

Test "remote" connection

1 # From : dbsqware@sqwarebox
2 menu_mys TestInstConnectionDistNoMail GenLstInstanceNew

Starting the Instance

Generating the Default SQWareProduction Configuration

/!\ Only instances that will be in "ON" status!

1 # From : dbsqware@sqwarebox
2 menu_mys GenDefConf_SQWareProduction GenLstInstanceNew

Update SQWare Repository

In the dbSQWare repository via the administration console, update the status of the new MySQL/MariaDB instance (currently NEW) to the desired value (ON, DIST).

Testing the "Recovery" of Indicators

At this point, you can test the recovery of missing indicators (in principle, only the instances you have just integrated!).

1 # From : dbsqware@sqwarebox
2 ## for those with status "ON"
3 repind_mys
4 ## for those with status "DIST"
5 repind_mys_dist

Operation (stats, backups, etc.) for "ON" instances

Generating SQWareProduction configs

If you followed the instance insertion procedure, this part is already done by step "menu_mys GenDefConf_SQWareProduction GenLstInstanceNew".
You can check with the next chapter.

Connect to the machine that has the “MySQL/MariaDB” instance and type the following commands:

1 # From dbsqware@vmyswarebox
2 c MYS_INST_PRD

1 #Source de l'env si multi-instance (from mysql@my_mysql_host)
2 e MYS_INST_PRD

1 too
2 ./sqwmys_GenerateCreateInstance.ksh -dbsOnly

Vérifier que ce qui est proposé est bon et tapez « y » si c’est le cas.
A ce moment, vous avez généré les fichiers de configuration par défaut de SQWareProduction.

Startup

Setting up cron:

1 mv $HOME/CrontabRef_MYS_INST_PRD $HOME/CrontabRef
2 vi $HOME/CrontabRef
3 crontab $HOME/CrontabRef
4 crontab -l

Update the file CrontabRef  :

1 crontab -l > $HOME/CrontabRef
2 cat $HOME/CrontabRef

Useful commands

alias : e DBALIAS => source env for the instance bin, etc, too ... => to go to the standard SQWareProduction tree cbin, cetc, ctoo ... => to go to the custom SQWareProduction tree log => SQWareProduction logs dmp => go to the backup paths

Some script options: -h => online help -s => online examples -Exec => when present; if not set, only outputs commands without executing them.
