OK, some time available while waiting for an install to finish ... This is a summary of the E812 StandAlone Installation document, revised October 2006.
1) MTR for E812 StandAlone: Acrobat 4 or higher, MDAC 2.71 or higher, MS Visual Studio .NET 2003, and Sun Java JDK 1.4.2. Double check that your iteration of the software still has these requirements.
2) All previoius releases of E1 should be uninstalled (or maybe SNAPSHOT out of the way).
3) Download (or however you got a hold of it) and unZip the software.
4) Set up using InstallManager.exe, and do the Base Components first.
5) Copy the JDBJ.INI file from BaseComponents\Client to \E812\system\OC4J\j2ee\home\applications\webclient.ear\webclient\WEB-INF\classes. If the file already exists, overwrite it with the one from BaseComponents\Client.
6) Now install the Data Components.
7) Create an ODBC entry called "EnterpriseOne Local" using the SQL Server driver, and pointing to (local)\JDELocal. You should use Windows authentication.
8) Verify that your JDBJ.INI has the [JDBj-BOOTSTRAP DATA SOURCE] section set for "System Local", databaseType=N, database=EnterpriseOne Local, and physicalDatabase=JDESY812.
9) Also check that [JDBj-SPEC DATA SOURCE] points to "Local - DEMO Specs" with the same databaseType and database. The physicalDatabase=SPEC_MASTER, however.
10) Also verify that the Oracle and SQL Server JDBC driver lines are active.
11) Verify that your JDE.INI file, [DB System Settings] section, has a line for Database=EnterpriseOne Local, and that the [LOCALWEB] section has Spec Datasource=Local - DEMO Specs.
12) Get the MS SQL Server 2000 JDBC drivers (SP2 or higher) and run the installation routine. Copy the 3 .jar files to \E812\system\OC4J\j2ee\home\applib.
13) Run REGEDIT, and locate HKEY_LOCAL_MACHINE\SOFTWARE\JDEdwards\HTML WebServer. Check that the value for JDBCDrivers points to the directory where you copied the 3 .jar files for the MS SQL Server 2000 JDBC.
14) Download and install Sun Java JDK 1.4.2 or whatever version is currently required. When you run the installation, make your destination a temporary file location.
15) From your temporary JDK destination, copy the folders bin, include, jre, and lib to \E812\system\JDK.
16) This is the part where I don't understand how you can install this without having Oracle support of some kind. You now have to obtain and enter the Oracle SPC authorization code.
I hope this helps a few people.
