Procedure 1.1. Pre-Installation Steps

Before installing the JBossJTA software, we recommend the following administrative steps be taken, assuming a default configuration for JBossJTA.

1. Install the distribution into the required location.

   Typically, the distribution is extracted from a .ZIP file.

2. Specify the Location for the Object Store

   JBossJTA requires a minimum object store for storing the outcome of transactions in the event of system crashes. The location of this should be specified in the properties file using the ObjectStoreEnvironmentBean.objectStoreDir key or by using environment variable:

   java –DObjectStoreEnvironmentBean.objectStoreDir =C:\temp foo.

3. Optional: Specify the sub-directory within the Object Store root.

   By default, all object states will be stored within the defaultStore/ sub-directory of the object store root. For instance, if the object store root is /usr/local/Arjuna/TransactionService/ObjectStore, the subdirectory /usr/local/Arjuna/TransactionService/ObjectStore/defaultStore/ is used.

   To change this subdirectory, set the ObjectStoreEnvironmentBean.localOSRoot or com.arjuna.ats.arjuna.objectstore.localOSRoot property variable accordingly.
