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,

<div><p> The default value is *LOCKWAIT. You can specify any number of seconds

the save-while-active operation will wait indefinitely. If 0 is specified,

all objects being saved must be at commit boundaries.</p>

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
