Issue/Introduction

Is it possible to resize Sysview logstream XLOG and make this change effective without having to bounce Sysview?

Environment

Release : 16.0

Component : SYSVIEW

Resolution

The Logstream can be modified using IBM utility (UPDATE LOGSTREAM command), after any connection to the logstream  has been dropped.

On the ASADMIN display, use the STOP command against the CICSLOGR subtask to stop it.


From ASADMIN, look for the entry:

Jobname   Task Id                              Status
SYSVIEW  CICSLOGR CICSLOGR ACTIVE

Enter STOP into the Cmd area next to the task.
The Status should become INACTIVE.

In the SYSVIEW STC log it should show that the task has been stopped.


GSVX573I (CICSLOGR) CICSLOGR task termination started
GSVX594I (MAIN) CICSLOGR task ended, completion code 0
GSVX574I (MAIN) CICSLOGR task termination complete
GSVX638I (MAIN) CICSLOGR task detached :

And from a SYSVIEW session the LGLOGS display should show the Loggers as Inactive:


CICSLOGR.EITL INACTIVE
CICSLOGR.SYSD INACTIVE
CICSLOGR.TRAN INACTIVE
CICSLOGR.TSUM INACTIVE
CICSLOGR.XLOG INACTIVE


Implement the changes and, when done, from the ASADMIN panel, enter START into the Cmd area next to the task, to restart the CICSLOGR subtask.
