What is the difference between warm start and cold start?
A hot start refers to when your app’s process is already running in the background. This makes it a lot faster than a cold start because the app’s activity is already present in memory. The system doesn’t have to repeat the initialization so it has much less overhead.
What is cold start and warm start in PLC?
Restart (warm restart) Program processing starts anew. Retentive data is retained. Cold restart. Current data is discarded and program processing begins again with the start values.
What is cold start in CICS?
The region has not previously been started. When you specify that a CICS region is to be cold started, no attempt is made to recover any previously running transactions, and any data that is stored in the transient data queues and temporary storage queues is lost. That is, the region starts as if for the first time.
What is cold start in PLC?
Cold Star start refers to starting the CPU from power off, Current configuration is discarded and program processing begins again with the initial values… PLC Hot start: Hot start refers to restarting the CPU without turning the power off, Program processing starts once again where Retentive data is retained.
Is cold start bad for car?
It’s a common occurrence as low temperatures can cause your car battery to produce less current, making it that much harder for your engine to turn over in the morning. The cold can also stop your engine oil from flowing as well as it should, which puts even more strain on the battery.
What cold start means?

What happens during a cold start?
Summary: During cold-start, a car engine emits far more particulate matter and other pollutants than during warm conditions. This is because a cold catalytic converter is much less efficient at low exhaust gas temperatures.
What happens to CICS on a warm start?
On a warm start, any changes that are made through the CEMT transaction or the EXEC CICS SET command are not restored. The previous run of the CICS region terminated abnormally, for example, with an immediate shutdown or a hardware error.
What is the difference between warmstart and coldstart?

When to use cold start or warm start?
The first time you start a region after creating it, you must use a cold start to ensure correct region initialization. When the cicscp start region command is used, the command checks whether it is the first time the region is being started.
What happens to the engine during a cold start?
During cold starts the ecu injects additional fuel to warm up the engine (warm up enrichment) this is typically in process till the engine reaches operating temperatures and has a minimum threshold limit. Also note closed loop will not come on till the O2 sensor is warm enough to start sending out signals.
