Glassfish JMS broker perzistující zprávy do Sybase ASE

Co budeme potřebovat:
  1. Oracle Glassfish 3.1.2.2 Dále je předpokládáno umístění v ~/glassfish3122
  2. Sybase Adaptive Server Enterprise 15.5
  3. JMS broker (integrovaný v Glassfishi)
  4. JDBC konektor pro Sybase ASE - jConnect 7.0.7
Postup:
1) Ve webové administraci serveru Glassfish otevřeme Configurations->server-config->Java Message Service. JMS Service Type nastavíme na hodnotu LOCAL. Poté v Additional Properties postupně nastavíme následující:
 <property name="imq.persist.store" value="jdbc"></property>  
     <property name="imq.persist.jdbc.sybase.driver" value="com.sybase.jdbc4.jdbc.SybDriver"></property>  
     <property name="imq.persist.jdbc.sybase.user" value="db_user"></property>  
     <property name="imq.persist.jdbc.sybase.password" value="db_user_passwd"></property>  
     <property name="imq.persist.jdbc.dbVendor" value="sybase"></property>  
     <property name="imq.brokerid" value="testBroker"></property>  
     <property name="imq.autocreate.reaptime" value="1"></property>  
     <property name="imq.instanceconfig.version" value="300"></property>  
     <property name="imq.jmsra.managed" value="true"></property>  
     <property name="imq.persist.jdbc.sybase.closedburl" value="jdbc:sybase:Tds:IPAddress:port/database"></property>  
     <property name="imq.persist.jdbc.sybase.opendburl" value="jdbc:sybase:Tds:IPAddress:port/database"></property>  
 Toto je samozřejmě možné zadat i v souboru config/domain.xml příslušné domény.
Pokud se rozhodnete namísto com.sybase.jdbc4.jdbc.SybDriver použít com.sybase.jdbc4.jdbc.SybDataSource nejspíš vás v logu bude čekat tato chyba:

Pokud se budete snažit použít některý ze starších ovladačů od Sybase, například verze 6.0, bude v logu chyba následující:

2) Abychom mohli používat JDBC ovladač pro Sybase ASE uvedený v kroku 1, musíme o něm dát JMS brokerovi vědět. To uděláme v souboru ~/glassfish3122/mq/etc/imqenv.conf přidáním řádku s cestou k ovladači: IMQ_DEFAULT_EXT_JARS=~/glassfish3122/glassfish/lib/jconn4-7.0.7.jar V uvedeném umístění samozřejmě musí tento soubor existovat.
Pokud cesta k ovladači nebude uvedena správně, objeví se v logu chyba:

3) Jelikož JMS broker nepodporuje Sybase ASE je třeba pro Sybase ASE vytvořit databázové schema. Na konec souboru ~/glassfish3122/glassfish/domains/domain1/imq/instances/imqbroker/props/config.properties je třeba přidat následující položky:

 #  
 # User name used to open database connection. Replace username.  
 #imq.persist.jdbc.sybase.user=<username>

Více o konfiguraci JMS brokeru je uvedeno zde.
Nyní stačí zapnout Glassfish a zkontrolovat zda se v databázi vytvořili tabulky uvedené ve schematu. Poté je už možné využívat JMS.
V případě zájmu si můžete přečíst více o konfiguraci persistentního uložiště pro Oracle Glassfish Message Queue.
