    Which of the following values needs to be set for the temn.tafj.locking.mode property in properties file if the database is MS SQL?

    • MSQL

    • ORCL

    • DATABASE

    • MEM

    Correct Answer
    A. MSQL
    Explanation
    The correct answer is MSQL because the temn.tafj.locking.mode property needs to be set to MSQL in the properties file if the database being used is MS SQL. This indicates that the locking mode for the database should be set to MSQL in order to ensure proper functionality and compatibility.

    What are the activities performed by DBImport during the JBASE to RDBMS conversion?

    • Create VOC entries for tables

    • Insert Records

    • Create Views

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    During the JBASE to RDBMS conversion, the DBImport tool performs various activities. Firstly, it creates VOC entries for tables, which are essential for defining the structure and properties of the tables in the RDBMS. Secondly, it inserts records from JBASE into the RDBMS tables, ensuring that the data is accurately transferred. Lastly, it creates views, which are virtual tables that provide a customized view of the data in the RDBMS. Therefore, all of the mentioned activities are performed by DBImport during the JBASE to RDBMS conversion.

    DBImport doesn’t support JR files.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement "DBImport doesn't support JR files" is false. DBImport does support JR files.

    Rate this question:

  • 5. 

    Suppose that view for a particular table is not created properly during DBImport, what is the best approach to rebuild the views in TAFJ?

    • Use REBUILD.SYS.FLDS in SS

    • Create view manually

    • Copy the DDL statement from another table

    • None of these

    Correct Answer
    A. Use REBUILD.SYS.FLDS in SS
    Explanation
    The best approach to rebuild the views in TAFJ is to use REBUILD.SYS.FLDS in SS. This command is specifically designed for rebuilding views and will ensure that the view is created properly during the DBImport process. Manually creating the view or copying the DDL statement from another table may not guarantee that the view is correctly created and could lead to further issues. Therefore, using the REBUILD.SYS.FLDS command is the recommended approach.

    Rate this question:

  • 6. 

    What does option (3) in DBUpdate do?

    • Single byte is converted to double byte.

    • For R13 releases. This is because view names were different in R13.

    • Single byte characters are left untouched. In tafj_conf.properties set the single byte related JVM setting.

    • None of the above

    Correct Answer
    A. Single byte is converted to double byte.
    Explanation
    Option (3) in DBUpdate does not convert single byte to double byte. Instead, it leaves single byte characters untouched. To handle single byte characters, the single byte related JVM setting should be configured in the tafj_conf.properties file.

  • 7. 

    It is possible to run DBImport for a specific file alone.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    DBImport is a tool used for importing data into a database. It allows users to specify the input file(s) they want to import. Therefore, it is possible to run DBImport for a specific file alone by providing the file path or name as an argument or parameter when executing the tool.

    Rate this question:

  • 8. 

    The only way to supply arguments for DBImport is through the wizard.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement is false because DBImport can also accept arguments through command-line options or configuration files, in addition to the wizard.

    Rate this question:

  • 9. 

    Design Studio is required for compiling jBC code in TAFJ.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Design Studio is not required for compiling jBC code in TAFJ. jBC code can be compiled using the jcompile command or by using the jBC compiler directly. Design Studio is a development environment for designing and building applications in TAFJ, but it is not necessary for compiling jBC code.

    Complex I-Descriptors (SUBR) are not supported with TAFJ.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Complex I-Descriptors (SUBR) are not supported with TAFJ. This means that TAFJ does not have the capability to handle or process complex I-Descriptors. Therefore, the statement "Complex I-Descriptors (SUBR) are not supported with TAFJ" is true.

  • 11. 

    It is possible to create UD directories in the RDBMS as part of DBImport process.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because during the DBImport process, it is possible to create UD directories in the RDBMS. This means that when importing data into the database, the process can also create user-defined directories to store the imported data. This allows for better organization and management of the data within the RDBMS.

    Rate this question:

  • 12. 

    Though CALLC is not supported, CallDotNet can still be used with TAFJ.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement suggests that even though CALLC is not supported, CallDotNet can still be used with TAFJ. However, this is not true. CALLC and CallDotNet are both methods used for integrating external programs with TAFJ, but they are not interchangeable. CALLC is used for C-based programs, while CallDotNet is used for .NET-based programs. Therefore, if CALLC is not supported, it is unlikely that CallDotNet can be used with TAFJ.

  • 13. 

    It is mandatory to provide the VOC path during DBUpdate.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    During DBUpdate, it is not mandatory to provide the VOC (Voice of the Customer) path. The VOC path is optional and can be provided if there is a need to include customer feedback or suggestions during the update process. However, it is not a requirement for the update to be successful. Therefore, the correct answer is False.

    Rate this question:

  • 14. 

    Which of the following is an invalid argument to DBImport?

    • –d

    • –makeDDL

    • –startwithfile

    • –endwithfile

    • None of these

    Correct Answer
    A. None of these
    Explanation
    The given options are all valid arguments to DBImport. Therefore, the correct answer is "None of these" as there is no invalid argument among the given options.

    Rate this question:

  • 15. 

    What is the name of the configuration file for DBUpdate?

    • TAFJDBUpdate.default

    • TAFJDBImport.default

    • Tafj.properties

    • None of the above

    Correct Answer
    A. TAFJDBImport.default
    Explanation
    The correct answer is TAFJDBImport.default. This is the name of the configuration file for DBUpdate.

    Rate this question:

  • 16. 

    A J4 Distributed file has 5 part files in a TAFC area. What will happen to the part files during DBImport?

    • All the part files will be converted as separate tables in RDBMS.

    • All the part files will be converted as a single table in RDBMS.

    • DBImport does not support the conversion of distributed files.

    • None of these.

    Correct Answer
    A. All the part files will be converted as a single table in RDBMS.
    Explanation
    During DBImport, all the part files in a J4 Distributed file will be converted as a single table in the Relational Database Management System (RDBMS). This means that the data from all the part files will be combined and stored in a single table in the RDBMS, allowing for easier management and analysis of the data.

    The property temn.tafj.jdbc.default.dict.type is set to CLOB while executing DBUpdate in TAFC RDBMS environment.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The property temn.tafj.jdbc.default.dict.type being set to CLOB indicates that the default dictionary type for the TAFC RDBMS environment is a CLOB (Character Large Object). This means that when executing a DBUpdate, any text or character data will be stored as a CLOB type in the database. Therefore, the statement "True" is correct.
