Sort two unsorted PS files into three different PS files with unique and common records.

• Use SORT utility to sort the two input files individually.

• Use JOINKEYS to join the two sorted files on a common key.

• Use OUTFIL to direct the output to three different files based on the record type.

• Ensure that the output files have unique records and common records as required.

Handling overflow condition of an array and backing up GDG versions in one step in JCL

• For overflow, check array bounds before accessing elements

• For SB37, increase primary/secondary space allocation

• For SD37, increase directory blocks

• For SE37, increase primary/secondary space allocation for PDS

• For S0C4, check for null pointers or uninitialized variables

• For S0C7, check for invalid data types or out-of-bounds array access

• To backup all GDG versions in one step, use the GDG base na...read more

Microflow is a flow with a rate of 1-1000 µL/min while nano flow is a flow with a rate of 1-1000 nL/min.

• Microflow is used in HPLC and capillary electrophoresis while nano flow is used in nano-LC and proteomics.

• Microflow requires larger sample volumes while nano flow requires smaller sample volumes.

• Microflow has lower sensitivity compared to nano flow.

To search a string from a ps file, use the grep command with the string and file name as arguments.

• Open the ps file in a text editor or use the command line to navigate to the file location.

• Use the grep command followed by the string you want to search and the file name as arguments.

• If the string is found, the command will return the line(s) containing the string.

• If the string is not found, the command will return nothing.

• You can also use regular expressions with the grep com...read more

Mendix has three types of entities: persistent, non-persistent, and microflow.

• Persistent entities are stored in the database and have a unique identifier.

• Non-persistent entities are not stored in the database and are used for temporary data.

• Microflow entities are used to define the input and output parameters of a microflow.

• Entities can have attributes, associations, and validations.

• Examples of entities include Customer, Order, and Product.

Equivalent of varchar(20) in COBOL and SQL error codes 805 and 922

• In COBOL, the equivalent of varchar(20) is PIC X(20)

• SQL error code 805 indicates program not found or not authorized

• SQL error code 922 indicates memory allocation failure

COBOL DB2 compilation process, CS vs RR, and Restart logic in COBOL program.

• COBOL DB2 compilation process involves precompilation, compilation, and linkage editing.

• CS (Change Strategy) and RR (Release Strategy) are two different methods of implementing DB2 changes.

• Restart logic in COBOL program is used to resume program execution from a specific point after an interruption.

• Restart logic can be implemented using checkpoints, savepoints, and restartable sections.

• CS involves mak...read more

To call a REST API, first identify the endpoint and required parameters. Then use a HTTP client library to send a request.

• Identify the endpoint and required parameters

• Choose a HTTP client library (e.g. Axios, Fetch)

• Send a request with the appropriate HTTP method (e.g. GET, POST)

• Handle the response and any errors

• Example: axios.get('https://api.example.com/data', {params: {id: 123}})

• Example: fetch('https://api.example.com/data?id=123', {method: 'POST'})

Types of entity refer to the different categories of objects or concepts that can be represented in a system or model.

• Entities can be physical objects, such as people or buildings, or abstract concepts, such as ideas or relationships.

• Entities can be further classified as unique or non-unique, depending on whether there can be multiple instances of the same entity.

• Examples of entities include customers, products, orders, invoices, and employees.
