Creating an Oracle Database Table using a SQL Script

Picking up where we left off at the end of part one, we shall create a database table. Copy the following SQL Script to the SQL Editor for the SYS@PDB1 connection.

CREATE TABLE wlslog(time_stamp VARCHAR2(255) PRIMARY KEY,category VARCHAR2(255),type VARCHAR2(255),
servername VARCHAR2(255), code VARCHAR2(255),msg VARCHAR2(255));

INSERT INTO wlslog(time_stamp,category,type,servername,code,msg) VALUES('Apr-8-2014-7:06:16-PM-PDT',
'Notice','WebLogicServer','AdminServer','BEA-000365','Server state changed to STANDBY');

INSERT INTO wlslog(time_stamp,category,type,servername,code,msg) VALUES('Apr-8-2014-7:06:17-PM-PDT',
'Notice','WebLogicServer','AdminServer','BEA-000365','Server state changed to STARTING');

INSERT INTO wlslog(time_stamp,category,type,servername,code,msg) VALUES('Apr-8-2014-7:06:18-PM-PDT',
'Notice','WebLogicServer','AdminServer','BEA-000365','Server state changed to ADMIN');

INSERT INTO wlslog(time_stamp,category,type,servername,code,msg) VALUES('Apr-8-2014-7:06:19-PM-PDT',
'Notice','WebLogicServer','AdminServer','BEA-000365','Server state changed to RESUMING');

INSERT INTO wlslog(time_stamp,category,type,servername,code,msg) VALUES('Apr-8-2014-7:06:20-PM-PDT',
'Notice','WebLogicServer','AdminServer','BEA-000361','Started WebLogic AdminServer');

INSERT INTO wlslog(time_stamp,category,type,servername,code,msg) VALUES('Apr-8-2014-7:06:21-PM-PDT',
'Notice','WebLogicServer','AdminServer','BEA-000365','Server state changed to RUNNING');

INSERT INTO wlslog(time_stamp,category,type,servername,code,msg) VALUES('Apr-8-2014-7:06:22-PM-PDT',
'Notice','WebLogicServer','AdminServer','BEA-000360','Server started in RUNNING mode');

Creating a Direct Connection in Toad for Oracle using Oracle  Instant Client                

As mentioned earlier, Toad for Oracle provides two options for connecting to Oracle, using the tnsnames.ora file, which we have already discussed, and using a direct configuration of the connection parameters, which we shall discuss next. For the Direct option a “Direct” tab is provided in the same New Connection wizard to create a connection using a tnsnames.ora file. To be able to use the Direct option we need to download and install the Oracle Instant Client. The version of the Oracle Instant Client should be the same as the Oracle Database version. Delete the Oracle Database Cloud Service previously created and create another database service using version, as shown in Figure 73. Enable the Access Rules as before.

Figure 73. Oracle Database Cloud Service with Version

Download the Instant Client for Microsoft Windows (x64) for Version ( from Extract the file and double-click on the .exe file to install the Oracle Instant Client in the C:instantclient_12_1 directory.  The VC10, VC11 and VC12 directories should be subdirectories of the C:instantclient_12_1 directory.  Add the directory C:instantclient_12_1 to the beginning of the PATH environment variable. Delete the local Oracle Database 12c installation, which was used to connect using tnsnames.ora file.


Adding a Login Record

Start the New Connection wizard from Session in the toolbar as discussed earlier.  In the New Connection wizard click on Add Login Record as shown in Figure 74.

Figure 74. Add Login Record

Select the Direct tab as shown in Figure 75.  Specify Host, Port, and Service Name.  Select Connect as: SYSDBA. The connection parameters’ values shown in Figure 75 are discussed subsequently.

Figure 75. Selecting the Direct tab

Obtain the Public IP Address for the Oracle Cloud Service and specify in the Host field for the Direct tab as shown in Figure 75. Obtain the service name and specify it in the Service Name field in the Direct tab. Obtain the Service name and the Public IP Address from the Oracle Database Cloud Service dashboard as shown in Figure 76.  The Public IP ( is listed in the Resources section of Service Overview.  The service name is obtained from the Connect String; the service name is the substring following the “/”.   Specify Port as 1521.

Figure 76. Getting the Connect String

In Connect Using select the Instant Client option, which should be available if the Instant Client has been installed, as also shown in Figure 75. Select the button for the Instant Client to display the settings used, as shown in Figure 77.
