APAR status

  • Closed as program error.

Error description

  • Logdefer delays of 1 and 2ms are being treated the same as no
delay time(i.g. 0ms).

Local fix

  • APAR to improve granularity of LOGDEFER setting.

Problem summary

  • ****************************************************************
* USERS AFFECTED: All.                                         *
****************************************************************
* PROBLEM DESCRIPTION: SIT LGDFINT parameter settings of 1 or  *
*                      2 may not be honoured.                  *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
If System Initialization parameter LGDFINT is set to a value of
either 1 or 2 it may be treated the same as if it had been set
to 0.
For LGDFINT values that are less the system defined
min_interval of 3 milliseconds, they are treated as being zero.
As a result LG_DEFER does not suspend for the required time and
there is no delay in the forced journal write requests.

Additional keywords: LOGDEFER

Problem conclusion

  • DFHL2SRC has been updated so the min_interval is changed from 3
to 1 to ensure LGDFINT values of 1 or 2 will always be honoured.

Temporary fix

  • FIX AVAILABLE BY PTF ONLY
