standard on 7.1 where you can create the new threshold value
via the data area QMAXJOBPCT. <<SNIP>>

The function provided by that data area provides nothing more than an override to the percentage at which the message is first issued and the effect of continued warning for the condition. Prior to that feature addition, the percentage was notified at the hard-coded value of 90%, notified "each time the job tables are extended after 90% of the maximum has been reached". With the request to CRTDTAARA DTAARA(QSYS/QMAXJOBPCT) TYPE(*DEC) LEN(2 0) VALUE(70) AUT(*EXCLUDE) the notification could begin instead at 70%, or similarly using CHGDTAARA DTAARA(QSYS/QMAXJOBPCT) VALUE(80) [if the data area already exists] to cause notification to begin at 80%... after activation, either by a PwrDwn\IPL or issuing CHGSYSVAL QMAXJOB [¿to effect a modified value; i.e. presumably, other than *SAME?].

When a feature is implemented via a *DTAARA [or similar means in a disconnected or non-integrated fashion], introduced as a PTF to an existing release, the general [and mostly safe] assumption is that the feature will continue to function unchanged until such time that a replacement feature has been provided via an /integrated/ function, perhaps as an API, command, and\or menu interfaces [perhaps a system value, modifiable via such interface(s)]. The replacement would be expected to be documented in the Memo to Users (MTU) and include the Data Area name as a token such that a search on the token QMAXJOBPCT within that document would enable anyone to locate the information about the replacement. Similarly a web search on that token should assist to verify [in an MTU or elsewhere]; e.g.:

"... the capability to customize the percentage at which this message <ed: CPF1468> is sent. PTFs for 5.4 (SI29585) and 6.1 (SI30171) provide this support (no PTFs are needed for 7.1 as this support is part of the operating system). You create a data area named QMAXJOBPCT in QSYS to control the percentage at which you want the warning message to be sent. See the PTF cover letters or the redpaper..."
