Review of Warm and Cold Start of CWM
Performing a Warm Start of CWM
A warm start of CWM consists of stopping the application, then restarting it. A warm start of CWM is
used without initializing the database, and can aid in overcoming database inconsistencies without losing
data. When you perform a warm start of CWM, the application continues to use data in the existing
Informix database.
To perform a warm start of CWM, complete the following steps:
Step 1 From the CWM main menu, enter 2 to select the Stop Core option, then confirm that you want to stop
core by responding y to the prompt.
It should take less than a minute for all of the processes and messages to end.
Step 2 Press Return to re-display the CWM main menu.
Step 3 From the main menu, enter 1 to select the Start Core option.
Step 4 When the CWM main menu is displayed, enter 3 to launch the CWM Desktop.
Performing a Cold Start of CWM
You perform a cold start of CWM when starting the application with an empty database. A cold start is
typically used following a CWM upgrade or if there were too many database inconsistencies within the
network for a warm start recovery to be successful. You can use the create_db, or coldstart -F or
Sv+CreateDb -F commands to build a new, empty database. These commands destroy any existing
data in the database including statistics and object comments.
Note The user needs to run updateftpinfo after a coldstart -F, or after a change has been made to
their UNIX password of svplus after installation.
Note In any degrade mode recovery procedure, the user data tables should be kept on the Primary
CWM in order to maintain all existing user data. This means that the user should not use
coldstart -F or SV+CreateDB -F on the Primary CWM or all of the existing user data will be
dropped from the database. Similar commands, SV+CreateDB or coldstart, can be used on the
Primary CWM to clear all of the network data, and as soon as a connection has been
re-established, the Secondary CWM will re-sync the user data tables with the Primary CWM.
To perform a cold start of CWM, complete the following steps:
Step 1 At the CWM workstation, enter CWM to display the main menu.
Step 2 From the CWM main menu, enter 2 to select the Stop Core option, then confirm that you want to stop
core by responding y to the prompt.
