Design and Development Tools

The WebLogic Workshop IDE is not supported on HP Integrity NonStop Server systems. HP Integrity NonStop Server is supported for the production deployment of applications developed in the WebLogic Workshop IDE. Debugging of applications developed in the WebLogic Workshop IDE, for deployment on HP Integrity NonStop Server, should be accomplished to the extent possible on the Workshop development system; use of JVM debug mode with the NonStop Server for Java significantly degrades application performance and debugging effectiveness. HP Integrity NonStop Server is also supported for the development and production deployment of WebLogic Server applications developed with other tools.

RAM

4 GB per processor required

QIO must be configured to use KSEG2.

Known Issues

Issue

Workaround

    1. Database Cascade Deletes Are Not Supported

NonStop SQL/MX 2.0 does not support cascade deletions on a table. As a result, any Container Managed Persistence (CMP) EJB that relies on the database cascade delete feature to delete the data from the SQL/MX database fails.

The deployment descriptor of an EJB should not contain db-cascade-delete in its weblogic-cmp-jar.xml. This enables WebLogic Server to delete rows using explicit SQL delete statements.

    2. Automatic Table Creation for EJB Container Managed Persistence (CMP) May Fail

Automatic table creation for a CMP EJB using the deployment descriptor tag create-default-dbms-table may fail in two situations:

(a) If the table contains column names that are keywords in NonStop SQL/MX.

(b) If the table includes a primary key column. NonStop SQL/MX 2.0 expects the primary key column to be qualified as NOT NULL NOT DROPPABLE. However, automatic table creation does not generate the NOT NULL NOT DROPPABLE clause.

(a) Make sure the CMP deployment descriptor does not use SQL/MX keywords as table column names.

(b) Make sure the table is created before the EJB is deployed so that the table schema exists when WebLogic Server checks for table information for the EJB.

    3. Sequence Entities Are Not Supported

Sequences/Identity columns are not supported in NonStop SQL/MX. Hence, automatic key generation for an EJB in WebLogic Server using sequences is not supported.

The automatic key can be generated using NamedSequenceTable as the value of the generator-type specified in the automatic-key-generation section of the weblogic-cmp-jar.xml file. The schema for the table name specified in the generator-name should have one column sequence of type Integer.

The following code shows a sample entry:

<automatic-key-generation>
<generator-type>NamedSequenceTable</generator-type>
<generator-name>sequencetable</generator-name>
<key-cache-size>10</key-cache-size>
</automatic-key-generation>

Table schema:

CREATE TABLE SEQUENCETABLE (SEQUENCE INTEGER);

    4. Deployment Error During Use of WebLogic 5.1-Style Deployment Descriptor

When an EJB has a WebLogic Server 5.1-style deployment descriptor, the EJB fails to deploy on WebLogic Server. The doctype for a 5.1-style descriptor is as follows:

<!DOCTYPE weblogic-rdbms-bean PUBLIC '-//BEA Systems, Inc.//DTD WebLogic 5.1.0 EJB RDBMS Persistence//EN' http://www.bea.com/servers/wls510/dtd/weblogic-rdbms-persistence.dtd'>

Convert the 5.1-style deployment descriptor to a WebLogic Server 7.0 (or later) style deployment descriptor. Some of the changes required are conversion of the pool-name tag to data-source-name and conversion of the attribute-map to a field-map. WebLogic Server provides a DDConverter utility to convert the beans from earlier versions of WebLogic Server. For further documentation about how to use the DDConverter utility, see the documentation at the following URL:

http://download.oracle.com/docs/cd/E13222_01/wls/docs81/ejb/implementing.html#DDConverter

    5. Certain CMP-Generated Code That Assumes Implicit Type Cast Conversion Fails

Certain instances of CMP-generated code based on the assumption of implicit type cast conversion fail. If the CMP-generated code assumes implicit type cast conversion (for example, conversion from string to integer), the SQL execution at run time fails. Implicit type casting of data types is not supported in NonStop SQL/MX 2.0.

None

    6. EJB-QL That Uses the SQL SUBSTRING Function Fails

Any EJB-QL that uses the SQL SUBSTRING function fails to execute because the parameters of the SQL/MX SUBSTRING function are different from the parameters used by other databases supported by WebLogic Server.

None

    7. Container Managed Relationship Caching Cannot Be Specified

Container Managed Relationship (CMR) caching cannot be specified when using NonStop SQL/MX 2.0.

None

    8. Only the "default database type" Is Supported for CMP

For CMP, no database types other than the default type are supported.

None

    9. SQL/MX 2.0 Triggers Have Restrictions

The use of SQL/MX 2.0 triggers is affected by several restrictions:

  • The trigger action must comprise just one statement.

  • The trigger action statement cannot be a call to a Java Stored Procedure.

  • "BEFORE"-type triggers can be used only to inspect or modify data, or to return SQLState or vendor error code information.

None

    10. Large Objects (BLOBs and CLOBs) Require Use of Special Tables

SQL/MX 2.0 MX Tables supports large objects (BLOBs and CLOBs) only with the use of special additional tables.

When a table contains a BLOB or CLOB column: These special tables must be pre-created for both production and development mode by users of WebLogic Server. The JdbcMxLobAdmin utility is the recommended facility for pre-creating tables that contain BLOB or CLOB columns, as well as for creating the special tables used to store the LOB data. The names of these tables must be specified to the JDBC/MX driver as properties in the Java options.

    11. Restrictions on Use of Native SQL/MX Utilities

SQL/MX 2.0 utilities, including mxci, cannot be used to insert, delete, or update data in tables that contain LOB columns.

Use the JDBC/MX V32 driver to perform these operations.

The following sections provide instructions for these tasks:

Before you begin, review all instructions.

Step 1: Download BEA WebLogic Server 8.1 SP3 and the Supplemental JAR File

  1. Go to the BEA Downloads site:

    2. http://commerce.bea.com/showallversions.jsp?family=WLS

  2. Download the WebLogic Server 8.1 SP3 package installer for HP Integrity NonStopTM Server (Itanium): pj_server813_generic.jar.
  3. Download the BEA supplemental file for HP Integrity NonStopTM Server: weblogic81sp3_hpns_h13_supp.jar. This JAR file contains HP Integrity NonStopTM Server-specific modifications to the standard BEA files that are provided with WebLogic Server 8.1 SP3 and the NonStop Server for Java 4.0.
  4. Verify that you have write permission for the root directory on the Integrity NonStop Server to which you plan to copy this software.
  5. Use ftp to copy BEA WebLogic Server 8.1 SP3 (pj_server813_generic.jar) and the supplemental JAR file (weblogic81sp3_hpns_h13_supp.jar) to an empty directory on the Integrity NonStop Server. If such a directory does not already exist, create one now: 
    6. $ mkdir -p /usr/tandem/wlhpns/download81sp3

    Make a note of the directory in which the server and supplemental JAR files have been copied. This directory will be used in subsequent steps.

Step 2: Download the HP NonStop Server Toolkit

  1. Download the NonStop Server Toolkit (weblogic81sp3_hpns_h13.zip) from the "Resources" section of the following HP download site:

    2. http://www.hp.com/go/nonstop/WLS81

  2. Use ftp to copy the downloaded file to the directory on the Integrity NonStop Server that contains the supplemental JAR file (weblogic81sp3_hpns_h13_supp.jar).

Step 3: Check Environment for Required Files

Before you proceed with the installation, verify that the following files are present on the Integrity NonStop Server:

Step 4: Install BEA WebLogic Server 8.1 SP3

  1. Before starting the installation process, verify the following:
  2. Set and export the environment variables required for use with NonStop Server for Java 4.0 and NonStop TCP/IPv6. Save the commands used for setting these variables in a file, such as your .profile.
    1. Set and export the environment variables listed in the following example settings:
      2. $ export JAVA_HOME=/usr/tandem/java
      $ export PATH=$JAVA_HOME/bin:$PATH
      $ export WL_HOME=/usr/bea/weblogic81
      $ export JDBCMX_DIR=/usr/tandem/jdbcMx
      $ add_define =PTCPIP^FILTER^KEY class=map file=mykey

      Note: The environment variables JAVA_HOME, PATH, and WL_HOME do not have default values. Set these variables to actual or intended locations before executing the check-wl-hpns.sh and install-wl-hpns.sh scripts.

    2. If your NonStop TCP/IPv6 process is not named $ZTC0, create a define to indicate the process name. For example, in the following add_define statement, the name of the TCP/IP process is $ZSM1. You must include an escape character before the $ that precedes ZSM1: 
      3. $ add_define =TCPIP^PROCESS^NAME class=map file=\$ZSM1
  3. Prepare to install WebLogic Server 8.1 SP3 on Integrity NonStop Server:
    1. Go to the directory in which you downloaded the NonStop Server Toolkit file (weblogic81sp3_hpns_h13.zip):
