Setting up a connection to the Oracle DBMS.

Setting - connect.jpg

Block "Connection list" - a list of saved connections with the Oracle DBMS

 

Creating a new connection
  • Select the "New" line in the "Connection list"

  • From the drop-down list "TNS string or Connection string" select the connection alias (priority method).

Connection aliases are extracted from the TNSNAMES.ORA file, the path to which is specified in the parameters on the "TNS" tab.

CerebroSQL comes bundled with the necessary libraries to work with all supported DBMS. By default, the program uses local libraries, including the local TNSNAMES.ORA file

  • specify the connection string in full format in the "TNS string or Connection string" block: <server name>: <port> / <servie_name>

The button in the "TNS string or Connection string" block is used to edit the tnsnames.ora file

  • Fill in the "Login" field - the username under which the connection is made

  • Fill in the "Password" field - user password

  • From the drop-down list "Connection mode" select the connection mode or leave it blank if "None"

  • "Comment" - comment, optional field

  • "System name" - the name of the system, the field is optional

  • "Type" - type of database, industrial, test

  • "TNS Block" - the text of the TNS block for connection, the field is optional

  • Click the "Save" button

To test the connection, use the "Testing" button

Bulk Testing All Stored Connections
  • Press the button "Test all"

  • In the window that opens, click the "Start test" button

  • Confirm the operation

After testing, connections that are not valid can be deleted with the "Delete" button

2. Through the installed client on the workstation

Editing parameters:

1. Set the check "Edit configuration"

2. Select a client from the drop-down list

2.1 <Local> - Local libraries

2.2 <Name of installed client> - previously installed client

3. Press the "Apply" button to apply the parameters

  • Work - In real time

  • Manual - Manual

  • Switch "Rename history file [tmp dir]" - On - rename temporary files of sheets of the previous session of the program, thereby preserving the work of the previous session.

  • Switch "Automatically save lists editor" - On - Enable the mechanism of automatic saving of the text of sheets of the query editor to a folder on disk. By default, sheets are saved to files in the directory .\Tmp\lists \<current_date>\ <List_name> .sql

  • Switch "Show log operation" - On - show a semi-transparent window with a log of operations in the current sheet.

  • Switch "Copy text new list" - On - when cloning the current sheet ( Ctrl + t ), copy the contents of the sheet into a new sheet.

Setting - monitoring.jpg

 

  • Switch "To chek the rigth on the object" - check the rights to tables / views when connecting to the database.

  • Switch "Save SQL text" - save the text of sql queries executed by active sessions. Data collection is performed by the process of collecting data on the load on the database

  • Switch "Automatically [ASH or Real-time]" - allow the program to automatically decide on the source of load data in the database. When ASH views are available, a decision is made to use them. If no views are available, the data is taken from the V $ SESSION view. It is recommended to disable this function.

  • Switch "Use mode Real-time" - use data from V$SESSION to form load profile. It is recommended to use the specified mechanism

  • Switch "Adjust the timer" - activation of this function forces the system core to adjust the start time of data collection providing a "strict" interval of 1 s. between the moments of the beginning of the execution of requests forming the ASH profile.

Changing the password for entering the program.

Clear ASH database

Cleaning and compressing the ASH.db base. This database stores data on the load on the database collected by the main core of the program. Since there is a large amount of data received from loaded databases, the specified database tends to grow. The cleanup operation allows you to reduce the size of the database without completely rebuilding it and losing data
