What does a file status of 02 on a VSAM indicate?
Re: VSAM file status 02. It is worth noting that the first digit of the file status code being a zero means that the operation was successful, even though the second digit can be 0, 2, 4, 5, or 7 to denote various conditions that did not prevent the operation but could impact the results.
How do I fix file status 46?
Re: How to solve File status code 46 for the below code You have to stop reading the second file when you find a match on the first file. That is the point of the “match key” having to exist. If you read to end of tile 2, then, yes, you will get the 46 for the first file 2 read for the second file 1 record.
What are the different types of VSAM files available?
You can use VSAM to organize records into four types of data sets: key-sequenced, entry-sequenced, linear, or relative record. The primary difference among these types of data sets is the way their records are stored and accessed.
What is file status code 46 in COBOL?
If a second sequential read is unsuccessful, a file status of 46 occurs and the AT END phrase is not executed.” When an AT END condition occurs, the READ is considered unsuccessful. This causes unpredictable results. The cause is the record contents returned to the program are UNDEFINED.
How do I open a Ksds file in COBOL?
OPEN OUTPUT or OPEN EXTEND for KSDS and RRDS files. (Either coding has the same effect.) If you coded the file for random or dynamic access and the file is optional, you can use OPEN I-O ….Opening an empty file
- Open the file.
- Use sequential processing ( ACCESS IS SEQUENTIAL ).
- Use WRITE to add a record to the file.
Is VSAM still used?
VSAM is used primarily for applications. It is not used for source programs, JCL, or executable modules. VSAM files cannot be routinely displayed or edited with ISPF. You can use VSAM to organize records into four types of data sets: key-sequenced, entry-sequenced, linear, or relative record.
Why VSAM files are used?
VSAM is used by programming languages in mainframes to store and retrieve data. VSAM files makes it easier for application programs to execute an input-output operation.
What does Cobol file status 49 indicate?

Which is faster VSAM or DB2?
So for huge data size Db2 is faster than VSAM because of lots of feautres which comes packed with DB2, sophisticated alogorithms etc.
