Because the business stops during FullGC occurrence, it is recommended that you suppress FullGC occurrence.

When you replace HCSC components online, you can suppress the frequency of FullGC occurrence by specifying the -nogc option in each operating command as shown in the following procedure example:

1. Stopping business processes and service adapters
   

   csccompostop -csc <HCSC server name> -name <serviceID> -nogc

2. Deleting business processes and service adapters
   

   csccompoundeploy -csc <HCSC server name> -name <serviceID> -nogc

3. Importing repositories
   

   cscrepctl -import <repositoryZIP> -compo

4. Deploying business processes and service adapters
   

   csccompodeploy -csc <HCSC server name> -name <serviceID>

5. Starting business processes and service adapters
   

   csccompostart -csc <HCSC server name> -name <serviceID> -nogc

Because FullGC occurrence is suppressed in steps 1~2, step 5, FullGC does not occur even once in the entire procedure in this example.
