Fix: Plsql script no output

 If you're running a PL/SQL script and not seeing any output, it could be due to various reasons. Here are some common troubleshooting steps to identify and resolve the issue:


1. **Check Output Destination**:

   - PL/SQL scripts in Oracle typically use the `DBMS_OUTPUT` package to display output. Make sure that you are checking the correct destination for the output. In many tools like SQL*Plus or SQL Developer, you may need to enable the DBMS_OUTPUT panel to see the results.


2. **SET SERVEROUTPUT ON**:

   - In SQL*Plus, you can enable output display by running the following command before executing your PL/SQL script:

     ```sql

     SET SERVEROUTPUT ON;

     ```


3. **Use DBMS_OUTPUT.PUT_LINE**:

   - Ensure that your PL/SQL script uses the `DBMS_OUTPUT.PUT_LINE` procedure to display output. For example:

     ```plsql

     BEGIN

       DBMS_OUTPUT.PUT_LINE('Output message');

     END;

     ```


4. **COMMIT or ROLLBACK**:

   - If you are performing database operations in your script, ensure that you issue a `COMMIT` or `ROLLBACK` command. In some cases, output may not appear until a transaction is completed.


5. **Error Handling**:

   - Check for errors in your PL/SQL script. If there are runtime errors, it might prevent the script from reaching the output statements. Use proper exception handling to capture and log errors.


6. **Permissions**:

   - Ensure that the user executing the script has the necessary privileges to use the `DBMS_OUTPUT` package and execute your script.


7. **Tool Configuration**:

   - Different tools and environments may have their own settings related to output display. Verify that your client tool (SQL*Plus, SQL Developer, etc.) is configured to display the output.


8. **Logging**:

   - If you are still facing issues, consider logging output to a table for debugging purposes. You can create a table and use `INSERT INTO` statements to capture and review your output.


9. **Check for Query Results**:

   - If you expect query results, ensure that you are selecting data from tables and displaying the results. If the query returns no rows, you may not see any output.


10. **Tool or Environment Issues**:

    - If you have tried the above steps and still see no output, there might be an issue with your specific database environment or client tool. Consider testing the script in a different environment or tool to see if the issue persists.


If you can provide more specific details about your PL/SQL script and the tools you are using, I can offer more targeted assistance.

bad character U+002D '-' in my helm template

 In Helm templates, the hyphen character (`-`) can sometimes be treated as a reserved character, particularly when defining values or labels. To include a hyphen character in a Helm template without issues, you can use one of the following approaches: 1. **Quoting the Hyphen:**    You can enclose the hyphen in double quotes, like this:    ```yaml    key: "-"    ```    This way, Helm will interpret the hyphen as a string rather than an operator. 2. **Using Backticks:**    If you need to use the hyphen within a Go template function or inside backticks, you can escape it with a backslash (`\`), like this:    ```yaml    value: `{{ .Values.someField | printf "%s \\-" }}`    ```    The backslash prevents Helm from interpreting the hyphen as a special character. 3. **Variable Assignment:**    Assign the value to a variable and use it. For example:    ```yaml    {{- $hyphen := "-" }}    key: {{ $hyphen }}    ```    This way, you can use the variable `$hyphen` wher

GitLab pipeline stopped working with invalid yaml error

 When your GitLab pipeline has stopped working with an "invalid YAML" error, it means there's a problem with your `.gitlab-ci.yml` file. This could be due to syntax errors, incorrect indentation, or other issues in your pipeline configuration. Here's how to troubleshoot and resolve this issue: 1. **Check for Syntax Errors**:    Carefully review your `.gitlab-ci.yml` file for any syntax errors. Common issues include missing colons, indentation problems, or mismatched quotation marks. Use a YAML linter or an online YAML validator to identify and correct syntax errors. 2. **Indentation**:    YAML relies heavily on proper indentation. Make sure that all lines within the same block have consistent indentation (typically using spaces, not tabs). Incorrect indentation can cause YAML parsing errors. 3. **Dashes and Lists**:    Ensure that you use the correct syntax for lists (arrays) in YAML by starting each item with a dash (`-`). Be consistent with your use of dashes throug

How do I add a printer in OpenSUSE which is being shared by a CUPS print server?

 To add a printer in openSUSE that is being shared by a CUPS print server, you can use the following steps: 1. **Ensure CUPS Client is Installed:**    Make sure your openSUSE system has the CUPS client tools installed. You can install them using the following command:    ```bash    sudo zypper install cups-client    ``` 2. **Discover Available Printers:**    Use the `lpinfo` command to discover available printers on your CUPS print server. Replace `cups-server-hostname` with the hostname or IP address of your CUPS server:    ```bash    lpinfo -v -h cups-server-hostname:631    ```    This command should list the printers shared by the CUPS server. 3. **Add a Printer:**    Use the `lpadmin` command to add a printer. Replace `printer-name` with the name of the printer you want to add and `printer-uri` with the URI obtained from the `lpinfo` command:    ```bash    sudo lpadmin -p printer-name -E -v printer-uri    ```    For example:    ```bash    sudo lpadmin -p MyPrinter -E -v socket://cu
