<div><p>The default value is 120 seconds. You can specify the amount of time to
|
|
wait for the object to become available. You can specify any number of seconds
|
|
from 0 to 99999 for object locks, or *NOMAX to have the save-while-active
|
|
operation wait indefinitely. If you end your applications before starting
|
|
the save operation, specify 0 seconds. If you do not end your applications,
|
|
specify a value large enough for your applications to make the objects available.</p>
|
|
<p>If an object is not available during checkpoint processing, the save-while-active
|
|
operation will wait up to the specified number of seconds for the object to
|
|
become available. While waiting for an object, the save operation does nothing
|
|
else. The save operation may have to wait for several objects. The total time
|
|
that the save-while-active operation waits may be much longer than the value
|
|
specified. If an object does not become available within the specified time,
|
|
the object is not saved, but the save operation continues.</p>

|
|
<div><p> The default value is *LOCKWAIT. You can specify any number of seconds
|
|
from 0 to 99999 for transactions with pending record changes. You use *NOCMTBDY
|
|
to save objects without waiting for commit boundaries. If you use *NOMAX,
|
|
the save-while-active operation will wait indefinitely. If 0 is specified,
|
|
all objects being saved must be at commit boundaries.</p>
|
|
<p>After the save-while-active operation allocates a group of objects that
|
|
it is synchronizing, it may then wait this many seconds for all jobs that
|
|
are using the same journals as these objects to reach commitment boundaries.
|
|
If these jobs do not reach commitment boundaries within the specified time,
|
|
the save operation ends. After 30 seconds, a CPI8365 message
|
|
is sent to the QSYSOPR message queue for each job for which the save-while-active
|
|
operation is waiting.</p>

any API commitment resource that is added without the option to allow normal

save processing. If you use *NOMAX there is no maximum wait time. You can

one name is specified for the Objects (OBJ) parameter, and *FILE is the only
