ストアの検証

検証は、次のことに使用できるツールです。

CLIのverifyコマンドを使用してストアの検証を実行します。パラメータは不要で、デフォルトでは冗長モードで実行されます。次に例を示します。

> java -Xmx256m -Xms256m \
-jar KVHOME/lib/kvstore.jar runadmin -port <registry port>> \
-host <hostname>
kv-> verify configuration

問題のみを表示するサイレント・モードを使用できます。

kv-> verify configuration -silent

ストアの問題が明確にレポートされます。たとえば、ストレージ・ノードが使用不能な場合、サイレント・モードでは、問題が次のように表示されます。

kv-> verify -silent

Verification violation: [rg1-rn2]

冗長モードでは、前述の問題が次のように表示されます。

注意

検証の出力は、コマンドの終了時にのみシェルに表示されます。検証の進捗を確認するには、Oracle NoSQL Databaseのログ・ファイルに対してtailまたはgrepを使用します。文字列Verifyを検索します。次に例を示します。

grep Verify /KVRT1/mystore/log/mystore_0.log
