Datasource Name Generation
The Development Client installation creates entries in the registry based on values in
            the Development Client installer oraparam.ini file located at:
\\<deployment server>\<release>\OneWorld Client
                Install\install\oraparam.ini
Assuming you have edited the oraparam.ini file as described in the section of this guide
            entitled: Update
                the oraparam.ini File, these entries are in the oraparam.ini
            file:
[Attributes] DataByPathCode=0|1 LocalDS=Local (this can be any string; the default value is "Local")
The registry entries on the Development Client machine after the Development Client is installed are located under:
HKEY_LOCAL_MACHINE\Software\Wow6432Node\Jdedwards\OneWorld\install.ini\<releasenumber>
In the above location, assuming the oraparam.ini file contains the
            requisite entries, these registry key values are assigned:
DataByPathCode=0|1LocalDS=some_string
Using these values, the WLSH4A and WASH4A installers create these datasource entries that point to the EnterpriseOne specs stored in a local database:
- Entry in the - jdbj.iniused by the web client:- [JDBj - SPEC DATA SOURCE] name= 
- Entry in the - jde.iniused by the Development Client:- [LOCALWEB] - Spec Datasource= 
For WLSH4A, the jdbj.ini file is located in this directory on the
            Development Client machine: 
<installpath>\system\JAS\EA_JAS_80.ear\webclient\WEB-INF\classes\jdbj.ini
For WASH4A, the jdbj.ini is located in this directory on the
            client machine: 
<installpath>\JAS\EA_JAS_80.ear\webclient.war\WEB-INF\jdbj.ini
The rules for generating the spec datasource name in the jdbj.ini and
                jde.ini are based on the values of the
                DataByPathCode and LocalDS in the
                [Attributes] section of oraparam.ini, which is
            located in this directory of the Development Client installer:
OneWorld Client Install\install
        
In hierarchical order, the rules are:
- DataByPathCode is 0 or missing - This condition indicates a shared local database. The datasource name will be "OneWorld Local" regardless of the value of LocalDS. - The following table shows the parameters used to create a datasource name that points to a local database: - ini File - Settings - oraparam.ini- [Attributes] DataByPathcode=0 or missing LocalDS is missing - jdbj.ini- [JDBj - SPEC DATA SOURCE] name=OneWorld Local - jde.ini- (Development Client machine) - [LOCALWEB] Spec Datasource=OneWorld Local 
- DataByPathCode is 1 and LocalDS is Missing - This condition indicates separate databases and LocalDS is missing. The datasource name will be "Local" followed by a hyphen and then the pathcode. - ini File - Settings - oraparam.ini- [Attributes] DataByPathcode=1 LocalDS is missing - jdbj.ini- [JDBj - SPEC DATA SOURCE] name=Local - <pathcode> - jde.ini- (Development Client machine) - [LOCALWEB] Spec Datasource=Local - <pathcode> 
- DataByPathCode is 1 and LocalDS is Set - This condition indicates separate databases and LocalDS is set. The datasource name will be the value of LocalDS followed by a hyphen and then the pathcode. - ini File - Settings - oraparam.ini- [Attributes] DataByPathcode=1 LocalDS=Local - jdbj.ini- [JDBj - SPEC DATA SOURCE] name=Local - <pathcode> - jde.ini- (Development Client machine) - [LOCALWEB] Spec Datasource=Local - <pathcode> 
The WLSH4A and WASH4A installers will update these strings in the ini files on the Development Client.
