Issue/Introduction

COLD and WARM start deferences.  

Environment

Release: ALL
Component: SYSVIEW

Resolution

WARM start

During a warm start, configuration information will be retrieved from the persistent data store. Configuration data from the previous invocation will be restored.
If the persistent data store does not contain the data requested, the definitions will be retrieved from parmlib members.

COLD start

During a cold start, configuration information will be retrieved from the PARMLIB member. Configuration data from the previous invocation will NOT be restored.

How is the start mode specified?
The start mode can be specified for the SYSVIEW Main Services address space and associated tasks. The User Interface address space does not support a start mode.
The start mode for the Main Services address space and each associated task can be different.
The default start mode for the address space and all tasks is WARMSTART.
If a COLDSTART is explicitly specified for the Main Services address space, a COLDSTART will be performed for all associated tasks even if the task has requested a WARMSTART.

Main Services Address Space

The start mode for the Main Services address space can be specified using three different methods.

  1. The start mode can be specified on the as part or MVS cmd that is used by the user manually or on scrip that used after IPL. 
    S SYSVIEW,START=COLD 
    S SYSVIEW,START=WARM
  2. The start mode can be specified using the START= parameter within the SYSVIEW started task PROCLIB member.
    //SYSVIEW PROC MEM=SYSVIEW,START=WARM       
  3. The start mode can be specified as an initialization option in the parmlib member specified by the MEM= parameter. The default member name is SYSVIEW.

    WARMSTART -or- COLDSTART
