IBM C9050-042 Exam Syllabus Topics:

IBM Developing with IBM Enterprise PL/I Sample Questions:

1. The following program was written to copy a dataset with record length of 100 to another dataset. If this
requirement has not been fulfilled, which is the most likely reason?
DCL DDIN FILE RECORD INPUT;
DCL DDOUT FILE RECORD OUTPUT;
DCL INSTRUC CHAR(100);
DCL EOF_IN BIT(1) INIT('0'B);
ON ENDFILE(DDIN) EOF_IN = '1'B;
DO UNTIL (EOF_IN);
READ FILE (DDIN) INTO(INSTRUC);
WRITE FILE(DDOUT) FROM(INSTRUC);
END;

A) The code does not fulfill the requirement because the input structure is the same as the output
structure.
B) The code does not fulfill the requirement because the OPEN statements are missing.
C) The code does not fulfill the requirement because too many records will be written to the output
dataset.
D) The code fulfills the requirement.

2. Which of the following is the most appropriate way of avoiding a recursive deadlock?

A) Setting a time limit on the runtime of the Transaction
B) Aborting the Transaction
C) Partitioning the relevant Database
D) Changing the program

3. Which of the following statements is best for avoiding synchronously updating a resource?

A) Have several programs update the resource without using ENQ.
B) Have only program A update the resource without using ENQ.
C) Lock the entire resource at start of program and release at end of program.
D) Have all programs use ENQ and WAIT for a specific resource.

4. Assuming there is no information about the duration or each table update and the programs are running in
a multitasking environment, which of the following options will best minimize the chance for deadlocks?

A) Program A updates Table A, Table B and Table C in the specified order, and Program B updates Table
C, Table B and Table A in the specified order.
B) Program A updates Table A, Table B and Table C in the specified order, and Program B updates Table
B, Table C and Table A in the specified order.
C) Programs update table A, Table B and Table C in random order.
D) All programs update Table A, Table B and Table C in the same order.

5. Prerequisite:
A sorted input dataset with record length 100 contains at least one record for all the values '1', '2', '3' in
the first byte. The applied sort criteria is 1,100,ch,a.
Requirements:
1 .) All records with '1' in the first byte must be ignored.
2 .) All records with '2' in the first byte must be written to the output dataset.
3 .) If there is a '3' in the first byte, the program must not read more records.
4 .) The program must not abend or loop infinitely.
If the following code does not fulfill the requirements above, which would be the reason, if any?
DCL DDIN FILE RECORD INPUT;
DCL DDOUT FILE RECORD OUTPUT;
DCL 1 INSTRUC,
3 A CHAR(1),
3 * CHAR(99);
DCL EOF_IN BIT(1) INIT('0'B);
DCL (Z1,Z2,Z3,ZO) BIN FIXED(31) INIT(0);
ON ENDFILE(DDIN) EOF IN = '1'B;
READ FILE(DDIN) INTO (INSTRUC);
IF EOF_IN THEN LEAVE;
SELECT(INSTRUC .A);
WHEN('1') DO;
Z1 += Z1;
ITERATE LAB;
END;
WHEN('3') DO;
Z3 = Z3 + 1;
LEAVE;
END;
WHEN('2') DO;
Z2 = Z2 + 1;
WRITE FILE(DDOUT) FROM(INSTRUC);
END;
OTHER DO;
ZO = ZO + 1;
PUT SKIP LIST(INSTRUC.A);
END; END;/*SELECT*/
END;/*LOOP*/

A) The code does not fulfill the requirement, because the program will loop infinitely.
B) The code does not fulfill the requirement, because the READ iteration will not be left when the first
record with '3' in the first byte appears.
C) The code does not fulfill the requirement, because not all records with '2' in the first byte will be written
to the output dataset.
D) The code fulfills the requirement.
