ADMININACTTIMEOUT

Specifies the maximum amount of time, in minutes, a Management Console user connection with a datastore can be inactive before an automatic disconnection is initiated on the zSeries server.

An inactive Management Console user connection to a datastore running in an CDC Replication address space prevents that address space from being shut down in a controlled manner. This setting lets you establish a timeout period for inactive connections to a datastore so that an attempt on the server to shut down the address space in a controlled manner will eventually be successful. After the timeout period has expired, CDC Replication ends the datastore connection automatically. CDC Replication replication that was activated before the datastore disconnection continues normally.

Note: The timeout period defined by this keyword is not the same as a datastore timeout setting in Management Console. The latter determines the maximum amount of time for a Management Console process to successfully establish a connection with a datastore running on a server. The former, which is an CDC for Db2® for z/OS® setting, determines the maximum amount of time an agent can be inactive after an agent connection has been successfully established.

After a timeout period expires, CDC Replication generates a message (CHC0556I) in the product administration log indicating that an automatic disconnection will be performed.

ADMININACTTIMEOUT=0 means that no timeout period is established for inactive Management Console user connections with the datastore. This behavior is consistent with previous CDC Replication versions, which means that a single connection can remain inactive for any length of time. Any positive integer assigned to ADMININACTTIMEOUT that is within the acceptable range enables a timeout and specifies the length of the timeout period.

Tip: The Management Console user is not likely to be aware that a timeout is about to occur. Therefore, if a timeout period needs to be specified, the timeout should be sufficiently long to accommodate normal pauses and periods of inactivity when working with Management Console to configure and initiate replication. A short timeout period, such as five minutes, could result in frequent disconnections that disrupt the flow of work in Management Console. As a guideline, you may want to set the timeout period to be consistent with the z/OS session timeout defined on your server.
