Referring to the sample code above, what is missing in the first macro in the PSBGEN job stream?

  1. The PSBNAME

  2. The PROCOPT

  3. The TYPE parameter

  4. The KEYLEN

  5. The NAME parameter

D Correct answer
Explanation

The KEYLEN parameter is a mandatory parameter on the IMS PCB macro statement to specify the maximum length of the concatenated key of all sensitive segments defined in the program communication block.

AI explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) The PSBNAME - This option is incorrect because the PSBNAME is not required in the first macro in the PSBGEN job stream. The PSBNAME is typically specified in subsequent macros.

Option B) The PROCOPT - This option is incorrect because the PROCOPT is not required in the first macro in the PSBGEN job stream. The PROCOPT is typically specified in subsequent macros.

Option C) The TYPE parameter - This option is incorrect because the TYPE parameter is not missing in the first macro in the PSBGEN job stream. The TYPE parameter is specified as "DB" in the first macro.

Option D) The KEYLEN - This option is correct because the KEYLEN is missing in the first macro in the PSBGEN job stream. The KEYLEN specifies the length of the key for the database being used, and it is necessary to define the KEYLEN for proper database operations.

Option E) The NAME parameter - This option is incorrect because the NAME parameter is not missing in the first macro in the PSBGEN job stream. The NAME parameter is specified as "VENDOR" in the TYPE parameter.

The correct answer is D. The KEYLEN is missing in the first macro in the PSBGEN job stream. This option is correct because the KEYLEN is necessary to define the length of the key for the database being used.
