QSYS is the only library that contains other library. QSYS is the root library where the entire user defined/ system defined library is created. System supplied libraries begin with the letter 'Q' or '#'. Library list types: System library: All IBM supplied library e.g. QSYS, QHLPSYS, QUSRSYS Product Library: Whenever Ibm product is used it is added to the library automatically and is removed itself when the job completes. Current Library: Current library is the working library i.e. All the work done by you is stored in current library.

User Library: Non-IBM supplied i.e. Candy Crush Saga Game Download For Blackberry Curve. Created by the user. For more information related to library and library commands: 4. Which library gets first loaded into the system when we login?

What is the purpose of QGPL library? Ans: QGPL (General Purpose Library) is subpplied by IBM. Normally, commonly used objects are placed in QGPL. So, that it can be used by all the users signed into that system. We can use QGPL library in below cases: Create an Output queues in QGPL so that the common printer can be used by everyone.

Create Commands in QGPL so that it can be used by all. Transfer object to QGPL LIBRARY on remote system, so that those transferred objects can be used by different users. In many cases, when you do not specify a library while creating object, then system will create object in QGPL. DSPFD FILE(ACCOUNT) TYPE(*MBR) OUTPUT(*OUTFILE) OUTFILE(*LIBL/OUT11111) After running above command, OUT11111 will be placed in QGPL as we mentioned *LIBL in library which is not specific. Hence system uses this general purpose library QGPL.

Hence, this General purpose library is used by System as well as by users. But, it is always advised to use your personal library instead of using QGPL.

How can we see all the objects and its sizes in a library? Ans: By using the command DSPLIB. Example: DSPLIB IROBO1 It gives you the information of all objects that resides in the library with it size. Display Library Library......: IROBO1 Number of objects.: 8 Type........: PROD Library ASP number.: 1 Create authority..: *EXCLUDE Library ASP device.: *SYSBAS Type options, press Enter. 5=Display full attributes 8=Display service attributes Opt Object Type Attribute Size Text PRINT1PGM *PGM RPGLE 131072 rpgle program for pri ACCOUNT *FILE PF 49152 ACCOUNT RELATED INFOR PRINT1 *FILE PRTF 4096 PRINTER DDS RLU GENER QCLSRC *FILE PF 8192 Sources CL-Programs QDDSSRC *FILE PF 8192 DDS-Sourcen QRPGLESRC *FILE PF 69632 QRPGLESRC2 *FILE PF 65536 QRPGSRC *FILE PF 8192 SOURCE PHYSICAL FILE Bottom F3=Exit F12=Cancel F17=Top F18=Bottom 7. What is source physical file? Ans: Source physical file is a file which contains the sources of different types of objects.

There can be up to 32768 members. Source physical file is an object. But the source member is not an object.

When we compile the member, the object is created for that source. Command used is CRTSRCPF.

CHGPF FILE(AMITNEM/OBJ) SRCFILE(AMINEM/QDDSSRC) SRCMBR(OBJ_SRC) We change the highlighted part to change the size of a file. Change Physical File (CHGPF) Type choices, press Enter. Physical file......... Name Library........... *LIBL Name, *LIBL, *CURLIB System............. *LCL *LCL, *RMT, *FILETYPE Source file.......... *NONE Name, *NONE Library...........

Name, *LIBL, *CURLIB Member size: Initial number of records.. *SAME 1-, *NOMAX, *SAME Increment number of records.

*SAME 0-32767, *SAME Maximum increments...... *SAME 0-32767, *SAME 11. How can we arrange duplicate records in a file? Ans: For this we will use file level keywords FIFO/LIFO/FCFO in the physical file. FIFO: The duplicate key records will retrieved in first in first out order. LIFO: The duplicate key records will retrieved in last in first out order. FCFO: The duplicate key records will retrieved in first changed first out order.

How to refer another file to define a new field in a physical file? Ans: below is an example, we are going to use the file REFER to get the field definition for new file.
