In-Depth Information
• The child JSTART process performs as a Java process, creates JVM, and loads it into
its address space and starts the OFFLINE DEPLOYMENT program.
• The OFFLINE DEPLOYMENT program executes the deployment steps in the data-
base.
Step 5:
• JIC reads the instance profile again searching for runLevel = 2.
• “BOOTSTRAP” node corresponds to runLevel = 2.
• JIC starts another JSTART process as a child process with parameters from the
BOOTSTRAP node and waits.
• The child JSTART process performs as a Java process, creates JVM, and loads it into
its address space and starts the BOOTSTRAP program.
• The BOOTSTRAP process synchronizes the binary data from the Java database to the
file system and updates the instance.properties file.
Step 6:
• JIC reads the recently updated instance.properties and startup.properties file searching
for runLevel = 3 or without any runLevel.
• This corresponds to ICM and Java server processes.
• ICM is started.
• Java server processes are started.
• A child process is started in each of the cases, and similar JVM actions are carried
over as in the preceding steps.
Step 7:
• The JIC process monitors the status of all the started cluster elements and takes actions
such as restarting terminated processes.
JSTART
You can check the JSTART process at the operating system level with the following UNIX
command:
