<h1 class="topictitle1">Maximum capacities</h1>
|

<div><p>If you exceed system limitations you can experience an application
|
||
|
|
outage or a system outage. Avoid these types of outages by being aware of
|
||
|
|
the maximum capacities and system limitations in advance. </p>
|
||
|
|
<div class="p"><img src="./delta.gif" alt="Start of change" /> Even though system limitations can be difficult to predict,
|
||
|
|
this topic can help you understand your system's maximum capacity. The tables
|
||
|
|
in this topic itemize some of the capacity limitations and restrictions that
|
||
|
|
can affect the availability of large systems and their applications. For example,
|
||
|
|
an online application halts when the size of a file or the number of its
|
||
|
|
members reaches the size limitation. These tables list the limits or maximum
|
||
|
|
values for V5R4. Some of these maximum values are different (lower) on prior
|
||
|
|
releases. Also, there are environments or configurations where the actual
|
||
|
|
limit may be less than the stated maximum. For example, certain high-level
|
||
|
|
languages can have more restrictive limits. These limits can range from a
|
||
|
|
certain number of objects to memory limitations. Memory limitations are measured
|
||
|
|
in megabytes, gigabytes, and terabytes.<div class="note"><span class="notetitle">Note:</span> The values listed in this topic
|
||
|
|
represent theoretical limits, not thresholds or recommendations. Approaching
|
||
|
|
some of these limits may be unreasonable and can degrade performance. Therefore,
|
||
|
|
practical limits may be lower, depending on system size, configuration, and
|
||
|
|
application environment.</div>
