10.2.1 How to start the EADS servers (creating caches in memory)

This subsection explains how to start the EADS servers and then create memory caches.

Organization of this subsection

(1) Start the EADS servers

Log in to the host on which you plan to start an EADS server, and then execute the ezstart command to start the EADS server. You must execute this command for each EADS server.

(2) Verify that initialization is finished

After an EADS server starts up successfully, it changes to initialized status.

Execute the eztool status command to verify that the initialization of all EADS servers is finished.

eztool status

Command execution example

If the initialization is finished, initialized is displayed in the State column.

(3) Create caches

Execute the eztool createcache command to create a cache for storing keys and values.

Command execution example

(4) Verify that caches have been created

Execute the eztool listcache command to display a list of caches.

Command execution example

Check the cache names in the CacheName column and the cache types in the CacheType column to verify that the caches have been created as intended.

(5) Open the cluster

As is the case with closed status, in initialized status, the EADS servers do not accept requests from the EADS client. Execute the eztool open command to open the cluster.

(6) Verify that the EADS servers have been opened

Execute the eztool status command to verify that all EADS servers have been opened.

If the EADS servers have been opened, running is displayed in the State column.
