I have finally been able to migrate the basic mySQL database structure and data to DB2, with the exception of one row that is contained in the XWIKIDOC table. The primary key for the row is XWD_ID = 104408758, XWD_NAME = XWikiPreferences. When I attempt to import this row into DB2, I get the following error. DB21034E The command was processed as an SQL statement because it was not a valid Command Line Processor command. During SQL processing it returned: SQL0102N The string constant beginning with "'head 1.8;\naccess;\nsymbols;\nlocks; strict;\ncomment @# @;\n\n\n1.8\" is too long. SQLSTATE=54002 Even though I was not able to load this row, I thought I might try to start the XWIKI servlet against the database. When I attempt to access the main page, I get the following error (see web error below). First question: Does anyone know how to get this row inserted, or is there a smaller alternate row that would suffice. Second question: Is this most likely the cause of the Tomcat exception (see TOMCAT Exception below) that I am receiving below? ----------------WEB ERROR-------------------------------------- type Exception report message description The server encountered an internal error () that prevented it from fulfilling this request. exception javax.servlet.ServletException: Error number 3 in 0: Could not initialize main XWiki context Wrapped Exception: Error number 3201 in 3: Exception while saving document XWiki.XWikiPreferences Wrapped Exception: Error number 3221 in 3: Exception while saving class XWiki.XWikiPreferences Wrapped Exception: Error number 3222 in 3: Exception while saving class XWiki.XWikiPreferences Wrapped Exception: could not delete: [com.xpn.xwiki.objects.classes.PropertyClass#component[id,name]{name=authenticate_edit, id=104408758}] org.apache.struts.action.RequestProcessor.processException(RequestProcessor.java:516) org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:423) org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:226) org.apache.struts.action.ActionServlet.process(ActionServlet.java:1164) org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:397) javax.servlet.http.HttpServlet.service(HttpServlet.java:689) javax.servlet.http.HttpServlet.service(HttpServlet.java:802) com.xpn.xwiki.web.SetCharacterEncodingFilter.doFilter(SetCharacterEncodingFilter.java:127) root cause com.xpn.xwiki.XWikiException: Error number 3 in 0: Could not initialize main XWiki context Wrapped Exception: Error number 3201 in 3: Exception while saving document XWiki.XWikiPreferences Wrapped Exception: Error number 3221 in 3: Exception while saving class XWiki.XWikiPreferences Wrapped Exception: Error number 3222 in 3: Exception while saving class XWiki.XWikiPreferences Wrapped Exception: could not delete: [com.xpn.xwiki.objects.classes.PropertyClass#component[id,name]{name=authenticate_edit, id=104408758}] com.xpn.xwiki.XWiki.getMainXWiki(XWiki.java:142) com.xpn.xwiki.XWiki.getXWiki(XWiki.java:202) com.xpn.xwiki.web.ViewEditAction.execute(ViewEditAction.java:117) org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:421) org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:226) org.apache.struts.action.ActionServlet.process(ActionServlet.java:1164) org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:397) javax.servlet.http.HttpServlet.service(HttpServlet.java:689) javax.servlet.http.HttpServlet.service(HttpServlet.java:802) com.xpn.xwiki.web.SetCharacterEncodingFilter.doFilter(SetCharacterEncodingFilter.java:127) note The full stack trace of the root cause is available in the Apache Tomcat/5.5.9 logs. ----------------TOMCAT EXCEPTION------------------------------- COM.ibm.db2.jdbc.DB2Exception: [IBM][CLI Driver][DB2/NT] SQL0532N A parent row cannot be deleted because the relationship "XWIKI.XWIKISTRINGCLASSES.FK300D1FCD99E425B2" restricts the deletion.
