ZAC L2506141

This Level introduces the following enhancements:

 

  1. Two new commands to display information on the z/OS Console about Lpars that belong

to groups. The commands are:

F ZCASC,DISPLAY ggg GROUP STALPA

and

F ZCASC,DISPLAY ggg GROUP PRMLPA

where ggg can assume any wildcard mask, like *GRP%, GR* or GR%%%

(* = any char and % = one char)

 

  1. New statement “COLLECT” to be defined in ASCLPAXX

 

This new statement is used to indicate if ZAC must reach a specific Lpar at startup.

If not specified, the default is COLLECT=Y.

Useful for Lpars that are not often active.

 

This new statement will introduce a behavior change.

Previously, at ZAC COLD START, it was necessary to SET Lpar COLLECT=N after ZAC

initialization.

Now, if COLLECT=N is defined in ASCLPAXX, it will set the COLLECT=N immediately, without the need to issue any command.

On the other hand, if the commands SET PRMLPA=xx or SET PARMS=xx are issued, they will reset the COLLECT status of the Lpar to what is specified in ASCLPAxx, even if the installation has changed the COLLECT status via MODIFY command.

 

In the first time ZAC is activated with level L2506141, a COLD start is mandatory.

ZAC L2504231

  1. Correction for message ASC0201E, which was indicating a wrong Lpar as the cause of the problem when ASCLPAxx is wrongly defined.

  2. If a Lpar was defined as AUTORELEASE=YES and this Lpar could not be reached by ZAC Monitor, wrong values are shown when selecting stacked DC information in CPC and GROUP web reports.
    The Lpar should indicate DC=0 in this case and it was not, although the calculations were correct.

ZAC L2501021

This Level introduces the following:

  1. Replacement of jquery and bootstrap libs into ZAC ZFS (/pgm/libs/jquery and /pgm/libs/bootstrap)

Observation:

It is not mandatory to replace ZAC ZFS because it continues to work normally, but if the customer feels more comfortable with newer releases of jquery and boostrap, the following procedures must be executed:

  • Unmount ZAC ZFS, mounted at /asc/pgm

  • Rename the current ZAC ZFS (IDCAMS ALTER)

  • Mount the renamed ZAC ZFS to any Unix directory (for backup purposes)

  • Using ZAC L2501021 DUMP, restore the new ZAC ZFS using ADRDSSU (ZAC Installation Manual – 4.1.1.2.4)

  • MOUNT the new ZAC ZFS on the current /asc/pgm and adjust BPXPRMxx if necessary (4.2.2.8.2)

  • Run job HTMMPUT from your SAMPLIB to adjust some files (4.2.2.8.3)

  • Run job ZFSCHOWN from your SAMPLIB to correct OWNERS (4.2.2.8.4)

  • Run job APCHCONF from your ZAC SAMPLIB (4.2.3.2.1)

ZAC L2411221

  1. Previously, if any Lpar managed by ZAC had its DC set to zero, ZAC's web interface showed no billing information for the Lpar and the CPC it belongs to. Now the billing information will be fully displayed, for all ZAC’s runmode.

  2. A new informative message ASC0054I will be shown, displaying the z/OS version where ZAC is executing

ZAC L2410181

Level L2403301 introduced an error in the field SMCPCPTS from SMF 225-1, wrongly appending an extra zerowhen this field is zero. Now, if SMCPCPTS is zero, it will be changed from 00000000000000 to 19000101000000 for clarity reasons.

ZAC L2409301

New control of maximum Lpars allowed based on what is specified in the License.


If the number of Lpars defined in ASCLPAxx exceed what is specified in the license, even if the CPUID matches, ZAC will stop the initialization.


Also valid for command REFRESHKEY, that dynamically reloads the license. In this case the license is ignored and a new one is searched.


If the number of Lpars exceed the definitions in ZAC, the new message ASC0964E will be issued, as below:


ZAC L2405301

This Level introduces the following:

Adjustment of billing calculation

ZAC L2403301

This Level introduces the following:

Correction for SMF 225 subtype 01 :  The peak time reported did not match that presented in the web report..

ZAC L2403151

This Level introduces the following:

1. Correction for SMF 225 subtypes 01 and 04 produced by ZAC. 

 When in CMP mode, subtype 01 was not reporting the billing peak and peak time of the last CPC. 

 In subtype 04, the last CPC was not written in CPC General Parameter Detail Section when in CMP mode. 

ZAC L2311221

This Level introduces the following:

 1.  Correction fot the Web Interface when there is a CPC defined with no Lpars.
The Web interface hided all CPCs and now it presents all of them, even the one with no Lpars

 2. REPORTDEPTH parameter was enhanced to support 48H (when INTERVAL=60s) or 96H (when INTERVAL=120s).  

The samples to be presented now have are limited to 2880 instead the previous 2160.  
If the customer specify more than 48 or 96 on REPORTDEPTH statement, using the respective INTERVAL parameter, ZAC will adjust the REPORTDEPTH to fit the new limit.

 3. A new functionality was introduced. 

In OPTIONS statement of ASCGENxx, if the last byte is set to 1, it indicates that if RUNMODE statement is about to be modified because of SET PRMGEN, SET PARMS or ACTIVATE PERIOD, a REPLY will be issued to confirm the RUNMODE change before it is done. 

 There are four new messages to address this new functionality (ASC0334I, ASC0335I, ASC0336I and ASC0337I).
The REPLY should be responded with Y within 30 seconds, otherwise the whole action will be cancelled.
 The default of OPTIONS statement is zero

ZAC L2309251

ZCOST.ASCV4400.L2308021 DUMP.XMI (If complete installation) or LOADLIB.XMI (If you have already installed ZAC 4.4).

This Level introduces the following:

  1.  Correction for License issues introduced in L2309071 (V4.4) 

  2.  Correction for the Web Interface when presenting WLM Service Classes graphs.  

 Sometimes the graph presents a continuous line connecting two intervals when the Service Class has no MSU consumed in the interval. Follows the before/after situation 

 

 Before 


After  


ZAC L2308021

ZCOST.ASCV4400.L2308021 DUMP.XMI (If complete installation) or LOADLIB.XMI (If you have already installed ZAC 4.4).

This Level introduces the following:

 The values of Cumulated MSU, presented in the Web interface, were not being reinitialized

when the billing month changes, causing the display of wrong information of column MMSU of both CPC and LPAR.

This new Level corrects it.

 Notes:

 The new LOADLIB must be assigned to all COLLECTORS, which can be WARM started. It’s not necessary to update all COLLECTORS at the same time, but only those with the new

LOADLIB will reset cumulated MSU when a new month enters (2nd day of the month).

There's no need to update ZFS for those who use and have already installed ZAC.

Fixes

Zetaly - 6577 - Correction about resetting MMSU data to zero at the start of each month

ZAC  L2305271

ZCOST.ASCV4400.L2305271 DUMP.XMI (If complete installation) or LOADLIB.XMI (If you have already installed ZAC 4.4). 

This Level introduces the following: 

  1.  Correction of ZAC algorithm to prevent abrupt changes on DC settings, keeping the DC more homogeneous and reducing CMP and CPC DC 

 

 First graph shows the situation before the fix. DC oscilates very abruptely 



Second graph shows the situation after the fix

This Level introduces the following: 

  1. Correction for memory overlay introduced in L2210211, which may cause abend S0C4 at different locations 

  2. Inclusion of new parameter BUFF for already existing command SET TRACE. 

Now, if command F ZCASC,SET TRACE BUFF is issued, ZAC will display information related to internal buffers, 

like offset and size. The command is for ZETALY diagnosis. 

This command do not activate a TRACE facility, it is a one-time event only, displaying the information requested.
