And in the Visualizer log, several errors are being highlighted, such as:

java.sql.SQLException: Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor


Release : 17.3



 After research located a Defect pertaining to the error DE58775.  Provided workaround:

Please try the following changes in the NX_ROOT\bopcfg\www\CATALINA_BASE_VIZ\webapps\CMDBVisualizer\WEB-INF\classes\application.conf file on the SDM server where Visualizer is deployed:

1. Locate the following line # dbPassword = "<override_dbUser_password>" Uncomment the line and enter the unencrypted password value for the MDBADMIN DB account. For example: dbPassword = Password1

2. Locate the following line # connectionURL = jdbc:sqlserver://localhost:1433;database=mdb Uncomment the line and provide the url with valid host, port and SID. For example connectionURL = jdbc:oracle:thin:@localhost:1521:mdb

3. Save changes to the file and restart the Visualizer Tomcat process and test if the Visualizer works, ie:

pdm_tomcat_nxd -c stop -t VIZ 

pdm_tomcat_nxd -c start -t VIZ

Client streamlined the process:


        # Database connection URL
        # Example for MS SQL - jdbc:sqlserver://localhost:1433;database=mdb
        # Example for Oracle - jdbc:oracle:thin:@localhost:1521:mdb
        connectionURL = "jdbc:oracle:thin:@HOST_NAME:1521/SERVICE_NAME"
        # Database user name - Example sys/sa/mdbadmin with Admin privilege
        dbUser = "USER"
        # Encrypted DB password, comes from SDM NX variables
        dbPassword = "PASSWORD"
