Ssaservice Component

Ssaservice is a daemon process. It parses the master XML file to get metadata information for the source tables. It also searches the required paths to find the list of flat files (source files exported from the database) to be loaded into each table, creates an archive job for each flat file, and adds the load job to the executor queue. Ssaservice passes required metadata information to ssajob through a temporary table-level XML file.

Ssaservice stores some internal information in the Data Vault metadata repository tables. During startup, ssaservice checks the current bulk file uploader metadata version and upgrades to the latest version. This metadata information is independent of the Data Vault metadata version.

Ssaservice uses the following command line syntax:

ssaservice -h (displays the help information) 
ssaservice start (starts the service process) 
ssaservice install (installs the daemon script "ssaserviced" in the Linux operating system)

On LINUX, the

ssaservice install

command creates a daemon script called "ssaserviced."

On Microsoft Windows, when you run

ssaservice install

, you are asked if you want to "use system account." If you select yes, the

ssaservice install

command will install ssaservice as a Windows service. To start the Windows service, use the command "

start ssaservice start

Informatica recommends that you stop the ssaservice with the ssamon utility. "Shutdown deferred" mode in ssamon terminates ssaservice after all of the running jobs are complete. Alternatively, you can stop ssaservice with "shutdown immediate." This command shuts down ssaservice and terminates any running jobs.
