<p>The Change Program (CHGPGM) command changes the attributes of a program without requiring that it be recompiled. The user can also force re-creation of a program even if the attributes being specified are the same as the current attributes.
|
|
</p>
|
|
<p>
|
|
<b>Note: </b>When the CHGPGM command is run on OPM programs which have a DMT (Dictionary Mapping Table), were created in V3R6M0, and have all observability removed, the DMT will be removed from the program object, and a message will be issued indicating a successful change.
|
|
</p>
|
|
<p><b>Restrictions:</b>
|
|
</p>
|
|
<ul>
|
|
<li>You must have object management (*OBJMGT) and use (*USE) authorities for the program that is to be changed.
|
|
</li>
|
|
<li>You must have at least *USE authority for the library where the program to be changed is located. You must also have delete (*DLT) and add (*ADD) authorities for the library in order to change the optimization attribute (OPTIMIZE parameter), performance collection attribute (ENBPFRCOL parameter), profiling data attribute (PRFDTA parameter), Licensed Internal Code options (LICOPT parameter), enable teraspace storage (TERASPACE parameter), or to force program re-creation by specifying FRCCRT(*YES).
|
|
</li>
|
|
<li>To change the user profile attribute (USRPRF parameter) or the use adopted authority attribute (USEADPAUT parameter), you must be the owner of the program, or be a member of the group profile that owns the program, or if your user profile (or one of your group profiles) has all object (*ALLOBJ) and security administrator (*SECADM) special authorities.
|
|
</li>
|
|
<li>Programs in the QSYS and QGDDM libraries cannot be changed, unless you are only removing observable information (RMVOBS parameter).
|
|
</li>
|
|
<li>The storage model (STGMDL) attribute of the program and all bound modules must be *SNGLVL to change a program to TERASPACE(*NO).
|
|
</li>
|
|
<li>Other jobs running the program may fail if the <b>Optimize program (OPTIMIZE)</b> parameter, <b>Use adopted authority (USEADPAUT)</b> parameter, <b>Enable performance collection (ENBPFRCOL)</b> parameter, <b>Profiling data (PRFDTA)</b> parameter, <b>User profile (USRPRF)</b> parameter, <b>Licensed Internal Code options (LICOPT)</b> parameter, or <b>Teraspace (TERASPACE)</b> parameter is changed, or program re-creation is forced by specifying FRCCRT(*YES).

<h3>Optimize program (OPTIMIZE)</h3>
|

<p>Specifies whether the program is optimized by the removal of redundant instructions. Changing the current optimization level of an Integrated Language Environment (ILE) program causes the system to re-create an ILE program with the new optimization level.
|
|
</p>
|
|
<p>The program must be re-created to change the optimization level. To be eligible for re-creation, OPM programs must have all observability and ILE programs must have all creation data, and the creation data must be observable. Use the Display Program (DSPPGM) command to determine whether a program is observable or has all creation data.

|
|
<dd>The program is at the most optimized level available for the release and language the program was created for (TGTRLS parameter when the program was created). In most cases, optimized programs make more efficient use of system resources. Specifying OPTIMIZE(YES) for ILE programs has the same effect as specifying OPTIMIZE(40).

|

<dt><b>40</b></dt>
|
|
<dd>This level includes all the optimizations performed at optimization level 30 (*FULL). In addition, it includes optimization that disables call and instruction tracing. Thus, tracing of modules created at this optimization level cannot be done. Specifying OPTIMIZE(40) for OPM programs has the same effect as specifying OPTIMIZE(*YES).

<dd>More optimization is performed in addition to those performed at optimization level 20 (*BASIC). Variables cannot be changed but can be displayed while the program is being debugged. However, the displayed value of the variable during debugging may not be its actual value. Specifying OPTIMIZE(*FULL) for OPM programs has no effect; a diagnostic message will be signaled.

</dd>

<dt><b>*BASIC or 20</b></dt>

<dd>For ILE programs, some optimization is performed on ILE programs. When debugging ILE programs at this optimization level, variables may be displayed, but the displayed value may not be the current value. Variables can also be changed but using the variables changed at this level may cause unexpected results. An informational message is sent and no operation is performed when OPTIMIZE(*BASIC) is specified for original program model (OPM) programs.

<h3>User profile (USRPRF)</h3>

The profiles of the program user or both the program user and the program owner are used to control which objects can be used by the program, including the authority the program has for each object. Only the program owner or a user with QSECOFR authority can change the user profile attribute.

<li>Some programs retain unobservable creation data even when observable creation data is removed. OPM programs created for release V5R1M0 or later (TGTRLS parameter when the program was created) will always contain creation data even when *ALL observability is removed.

<h3>Profiling data (PRFDTA)</h3>
|
|
<p>Specifies the program profiling data attribute for ILE programs. Program profiling is an advanced optimization technique to reorder procedures and code within the procedures based on statistical data (profiling data). An informational message is sent and *SAME is used if a value other than *SAME is specified for the PRFDTA parameter for original program model (OPM) programs.
|
|
</p>
|
|
<p>The program must be re-created to change the profiling data attribute. To be eligible for re-creation, the program must have all creation data, and the creation data must be observable. Use the Display Program (DSPPGM) command to determine whether the program has all creation data.

<h3>Licensed Internal Code options (LICOPT)</h3>

<p>Specifies individual Licensed Internal Code compile-time options to be selected, and is intended for the advanced programmer who understands the potential benefits and drawbacks of each selected compiler option. Changing the Licensed Internal Code options of an Integrated Language Environment (ILE) program to any value other than *SAME causes the system to re-create the ILE program.

<p>The program must be re-created to change the Licensed Internal Code options. To be eligible for re-creation, the program must have all creation data, and the creation data must be observable. Use the Display Program (DSPPGM) command to determine whether the program has all creation data.

<p><b>Example 1: Optimizing a Program</b>
|
|
</p>
|
|
<p>
|
|
<pre>
|
|
CHGPGM PGM(PROG1/SERVICE) OPTIMIZE(*YES) USRPRF(*OWNER)
|
|
</pre>
|
|
</p>
|
|
<p>The program SERVICE in library PROG1 is optimized, and the user profile under which it is processed is changed to include the program owner's user profile. Only the owner of program PROG1/SERVICE, or a user with security officer authority, can change the USRPRF attribute. The program is re-created only if the attributes specified differ from those of the current program.
|
|
</p>
|
|
<p><b>Example 2: Changing Text for a Program</b>
|
|
</p>
|
|
<p>
|
|
<pre>
|
|
CHGPGM PGM(*USRLIBL/KNUTE) TEXT('Program description')
|
|
</pre>
|
|
</p>
|
|
<p>This command changes the text for program KNUTE. The user portion of the library list is used to find the program.
|
|
</p>
|
|
<p><b>Example 3: Optimizing Multiple Programs</b>
|
|
</p>
|
|
<p>
|
|
<pre>
|
|
CHGPGM PGM(PROG1/ACE*) OPTIMIZE(*YES)
|
|
</pre>
|
|
</p>
|
|
<p>All programs in library PROG1 whose names begin with ACE, are optimized to their maximum optimization level.
|
|
</p>
|
|
<p><b>Example 4: Changing Text of Multiple Programs</b>
|
|
</p>
|
|
<p>
|
|
<pre>
|
|
CHGPGM PGM(PROG2/*ALL) TEXT('Generic Text')
|
|
</pre>
|
|
</p>
|
|
<p>This command changes the text of all programs in library PROG2 to 'Generic Text'.
|
|
</p>
|
|
<p><b>Example 5: Enabling Collection of Profiling Data</b>
|
|
</p>
|
|
<p>
|
|
<pre>
|
|
CHGPGM PGM(PROG1/PROFPGM) PRFDTA(*COL)
|
|
</pre>
|
|
</p>
|
|
<p>This command enables the collection of profiling data for program PROFPGM in library PROG1. If PROFPGM in library PROG1 had profiling data applied prior to issuing this command, all applied profiling data will be removed.
|
|
</p>
|
|
<p><b>Example 6: Applying Profiling Data</b>
|
|
</p>
|
|
<p>
|
|
<pre>
|
|
CHGPGM PGM(PROG1/PROFPGM) PRFDTA(*APYALL)
|
|
</pre>
|
|
</p>
|
|
<p>This command applies block order and procedure order profiling data to program PROFPGM in library PROG1. The collection of profiling data is no longer enabled for program PROFPGM in library PROG1.
