Sun Java System Application Server Enterprise Edition 8.2 Standalone Installer Release Notes

# Chapter 3 Known Issues and Limitations

This chapter describes known problems and associated workarounds for the Sun Java System Application Server Enterprise Edition 8.2 software. If a summary statement does not specify a particular platform, the problem applies to all platforms. This information is organized into the following sections:

This section describes known administration issues and associated solutions.

Bug ID

Summary

6171458

The package-appclient script does not work if domain1 is not present.

By default, there is a hard-coded value in $INSTALL/lib/package-appclient.xml for the AS_ACC_CONFIG variable for domain1 that is pointed to by asenv.conf. If domain1 is deleted and a new domain created, the AS_ACC_CONFIG variable is not updated with the new domain name, which causes the package-appclient script to fail. Solution Do one of the following: 1. Leave domain1 intact, and create your other domains around it. 2. Remove domain1 and replace the hard-coded value for domain1 in$INSTALL/lib/package-appclient.xml with the new domain name.

This will have to be done every time a new domain is created if domain1 is not present.

6196993

Cannot restore backed-up domain with another name.

Mirroring of a domain on the same Application Server installation cannot be performed using the backup-domain and restore-domain commands because the domain cannot be restored using a different name than the original, even though the asadmin restore-domain command provides an option to rename the domain. Renaming the backed-up domain appears to succeed, but attempts to start the renamed domain fail because the entries in the domain configuration are not changed, and startserv and stopserv use the original domain name to set paths.

Solution

The domain name used for restore-domain must be the same as that used for the original backup-domain command. The backup-domain and restore-domain commands in Application Server 8.1 work only for backing up and restoring the same domain on the same machine.

6200011

Starting Application Server with additional JMX Agent is not supported.

J2SE 1.4.x, 5.0, or later can be configured on the Application Server. An integral feature of J2SE 5.0 platform is the ability to start a JMX agent. This is activated when you explicitly set system properties at the server startup.

Example values include:

 name="com.sun.management.jmxremote" value="true" name="com.sun.management.jmxremote.port" value="9999" name="com.sun.management.jmxremote.authenticate" value="false" name="com.sun.management.jmxremote.ssl" value="false"

After configuring JMX properties and starting the server, a new jmx-connector server is started within the Application Server Virtual Machine. An undesirable side-effect of this is that the administration functions are affected adversely, and the Application Server administration Console and command—line interface may produce unexpected results. The problem is that there are some conflicts between the built in jmx-connector server and the new jmx-connector server.

Solution

If using jconsole (or any other JMX-compliant client), consider reusing the standard JMX Connector Server that is started with Application Server startup.

When the server starts up, a line similar to the one shown below appears in the server.log. You can connect to the JMXService URL specified there and perform the same management/configuration operations after successfully providing the credentials; for example:

 [#|2004-11-24T17:49:08.203-0800|INFO|sun-appserver-ee8.1|javax. enterprise.system.tools.admin|_ThreadID=10;|ADM1501: Here is the JMXServiceURL for the JMXConnectorServer: [service:jmx:rmi: ///jndi/rmi://hostname:8686/management/rmi-jmx-connector]. This is where the remote administrative clients should connect using the JSR 160 JMX Connectors.|#]

6206176

On UNIX, overly restrictive execute permissions on Application Server start and stop scripts.

If you run the asadmin restore-domain command while logged in as user "A", the scripts will end up with permissions as 744 (rwxr--r--). If you subsequently attempt to start or stop a domain as user "B" (even if "B" is root), it will fail because the scripts are only executable for "A".

Solution

Change the permissions on the scripts:

 chmod 755 appserv/domains/domain-name/bin/*

6236544, 6275436

Load balancer configuration file does not get created with the endpoint URL of any web service.

When setting up the load balancer configuration with an application that has an EJB module that exports a web service URL, the context root for the web service isn't in the resulting loadbalancer.xml file.

Solution

1. Edit the loadbalancer.xml file to add the missing web module as follows:

 
2. Replace context-root-name value with the context root name of the web service that was exposed as an EJB.

6288893

Application Server restart using sun-appserv-admin causes LoginException error.

Solution

1. Rename the existing <as_install>/bin/asant script to asant.bak.

2. Copy the asant.template file in <as_install>/lib/install/templates/ee (for SE/EE version) to the <as_install>/bin/ directory and rename the file asant.

3. Edit the newly copied <as_install>/bin/asant script, replacing the %CONFIG_HOME% token with <as_install>/config.

4. If there were any manual changes made to the original asant.bak file, merge them into the new asant script.

6315957

The .asadmintruststore file is not described in the Application Server documentation. If this file does not exist in the server administrator's home directory, you may experience serious bugs when upgrading certain applications hosted on the server.

Solution

• If possible, the asadmin start-domain domain1 command should be run by user who installed the server.

• If it is not run by that user, the .asadmintruststore should be moved or copied from the home directory of installing user to the home directory of the running user.

• Note that if the file is moved (not copied) from the installing user's home directory to the running user's home directory, you might experience application upgrade problems, as described in bugs 6309079, 6310428 and 6312869, because the upgrade/install user (normally root in Java ES) will no longer have the .asadminstruststore file in his or her home directory.

# Apache and Load Balancer Plugin

This section describes known Apache Web server and load balancer plugin issues and associated solutions.

Bug ID

Summary

6306784

The High-Availability Administration Guide contains incorrect instructions for using openssl with Apache.

Solution

When compiling and building openssl, run the following commands:

cd openssl-0.9.7e

config

make

Also, for Apache 1.3, the directory name of the mod_ssl source will vary depending upon the release of Apache used. For example, for Apache 1.3.33, the name is mod_ssl-2.8.22-1.3.33.

6307976

The High-Availability Administration Guide does not contain instructions for using a certificate for Apache 2.0.

Solution

To run Apache security, you must use a certificate. For instructions on obtaining a certificate from a certificate authority, see the information on certificates in the modssl FAQ.

6308021

Must start Apache Web Server as root.

Solution

On Solaris, if your Application Server was installed under root, you must start the Apache Web Server as root. Java Enterprise System installations are installed as root. For Apache 2.0, after starting as root, Apache switches and runs as another user you designate. You designate that user in the /conf/httpd.conf file. To start as root, on many systems you must edit the httpd.conf file to designate the correct group. Replace the line:

Group #-1

with

Group nobody

More information on user/group use is included in the httpd.conf file.

6308043

Addition to instructions for using openssl with Apache Web Server 2.0 on Solaris.

After installing Apache 2.0 and the load balancer plug-in, edit ssl.conf and sll-std.conf as follows:

Replace the line:

<VirtualHost _default_:9191>

with

<VirtualHost machine_name:9191>

Where machine_name is the name of your machine and 9191 is a security port number.

# Application Client

This section describes known application client issues and associated solutions.

Bug ID

Summary

6193556

Library JAR packaged in Application Client Archive overwrites MANIFEST file.

If you have a top level JAR file inside your client JAR (in this case, reporter.jar), when you deploy the client JAR, the MANIFEST file for that JAR overwrites the MANIFEST file for the client JAR.

Solution

None at this time.

# Bundled Sun JDBC Drivers

This section describes known bundled Sun JDBC driver issues and associated solutions.

Bug ID

Summary

6165970

Applications using the TRANSACTION_SERIALIZABLE isolation level with the bundled Sun driver for Microsoft SQL Server may hang when using a prepared statement to update if two parallel transactions are running and one of them is rolled back.

To set a desired isolation level for a connection, the corresponding connection pool must be created at that same isolation level. See the Administration Guide for details about configuring connection pools.

Solution

None at this time.

6170432

PreparedStatement Errors.

Description #1

If an application generates more than 3000 PreparedStatement objects in one transaction, the following error may occur with DB2:

[sunm][DB2 JDBC Driver] No more available statements.Please recreate your package with a larger dynamicSections value.

Solution #1

Add following properties to the connection pool definition to get the driver to rebind DB2 packages with a larger dynamic sections value:

createDefaultPackage=true replacePackage=true dynamicSections=1000

See the Administration Guide for details about configuring connection pools.

Description #2

Related to the PrepardStatement error above, another error message that may be thrown is:

[sunm][DB2 JDBC Driver][DB2]Virtual storage or database resource is not available.

Solution #2

Increase the DB2 server configuration parameter APPLHEAPSZ. A good value is 4096.

Description #3

Isolation level TRANSACTION_SERIALIZABLE. If your application uses isolation level TRANSACTION_SERIALIZABLE and uses one of the parameters suggested above, it might hang while obtaining a connection.

Solution #3

To set desired isolation level for a connection, the corresponding connection pool has to be created at that isolation level. See the Administration Guide for instructions.

6189199

Problems setting isolation level with the bundled Sun driver for Sybase Adaptive Server.

• Applications using the TRANSACTION_SERIALIZABLE isolation level with the bundled Sun driver for Sybase Adaptive Server may hang when using a prepared statement to update if two parallel transactions are running and one of them is rolled back. Connection rollback fails with following message, and the rolled back connections cannot be used anymore:

java.sql.SQLException: [sunm][Sybase JDBC Driver]Request cannot be submitted due to wire contention

• Sybase Adaptive Server does not support the TRANSACTION_REPEATABLE_READ isolation level. However, querying DatabaseMetaData, the bundled Sun driver returns that this isolation level is supported by the database. Applications using the this isolation level will fail.

• Applications using the bundled Sun driver cannot set the TRANSACTION_READ_UNCOMMITTED isolation level. The application throws the following exception on the first DataBaseMetaData access:

java.sql.SQLException: [sunm][Sybase JDBC Driver][Sybase]The optimizer could not find a unique index which it could use to perform an isolation level 0 scan on table 'sybsystemprocs.dbo.spt_server_info'.

Solution

None at this time.

6247468

On Solaris 10 and Enterprise Linux 3.0, the Sun bundled Oracle JDBC driver does not allow the creation of a connection.

Solution

Set the following property on the JDBC connection pool when using the SUN JDBC oracle datasource (com.sun.sql.jdbcx.oracle.OracleDataSource):

<property name="serverType" value="dedicated"/>

The value of the property depends upon the way the Oracle server's listener is configured. If it is configured in the "shared" mode, the above value needs to change to "dedicated".

# Connectors

This section describes known J2EE connector architecture issues and associated solutions.

Bug ID

Summary

6188343

After restarting a DAS instance, undeploying the connector module fails when cascade is set to false.

In this scenario, a standalone or embedded connector module is deployed in DAS and connector connection pools, and resources are created for the deployed module. After restarting the DAS instance, undeploying the connector module fails when cascade is set to false with the following exception:

Solution

Use cascaded undeploy (set the cascade option to true) for undeploying standalone and embedded connectors after restart of the DAS instance.

# Documentation

This section describes known documentation issues and associated solutions.

Bug ID

Summary

Various IDs

The Javadoc for several AMX interfaces and methods is either missing or incorrect:

• Getter methods for NumConnAcquired and NumConnReleased statistics are missing from ConnectorConnectionPoolStats and AltJDBCConnectionPoolStats. These getter methods will be added in a future release as getNumConnAcquired() and getNumConnReleased().

• Calling the following methods in EJBCacheStats will throw an exception: getPassivationSuccesses(), getExpiredSessionsRemoved(), getPassivationErrors(), getPassivations(). This will be fixed in a future release.

• The AMX MBeans may require several seconds after server startup before they are all registered and available for use. A future release will make it possible to determine when the AMX MBeans are fully loaded.

• The constant XTypes.CONNNECTOR_CONNECTION_POOL_MONITOR is misspelled ("NNN"). This will be corrected in a future release.

6265624

Bundled ANT throws java.lang.NoClassDefFoundError.

The following exception is thrown in thread main: java.lang.NoClassDefFoundError: org/apache/tools/ant/launch/Launcher.

Solution

Using the bundled ANT for activities outside the Application Server is not recommended.

# High Availability

This section describes known high availability database (HADB) issues and associated solutions.

Bug ID

Summary

no ID

HADB Configuration with Double Networks.

HADB configured with double networks on two subnets works properly on Solaris SPARC. However, due to problems in the operating system or network drivers on some hardware platforms, it has been observed that Solaris x86 and Linux platforms do not always handle double networks properly. This causes the following problems with HADB:

• On Linux, some of the HADB processes are blocked when sending messages. This causes HADB node restarts and network partitioning.

• On Solaris x86, some problems may arise after a network failure that prevent switching to the other network interface. This does not happen all the time, so it is still better to have two networks than one. These problems are partially solved in Solaris 10.

• Trunking is not supported.

• HADB does not support double networks on Windows 2003 (ID 5103186).

no ID

HADB Database Creation Fails.

Creating a new database may fail with the following error, stating that too few shared memory segments are available:

HADB-E-21054: System resource is unavailable: HADB-S-05512: Attaching shared memory segment with key "xxxxx" failed, OS status=24 OS error message: Too many open files.

Solution

Verify that shared memory is configured and the configuration is working. In particular, on Solaris 8, inspect the file /etc/system, and check that the value of the variable shmsys:shminfo_shmseg is at least six times the number of nodes per host.

5091280

hadbm set does not check resource availability (disk and memory space).

When increasing device or buffer sizes using hadbm set, the management system checks resource availability when creating databases or adding nodes, but does not check if there are sufficient resources available when device or main-memory buffer sizes are changed.

Solution

Verify that there is enough free disk/memory space on all hosts before increasing any of the devicesize or buffersize configuration attributes.

5091349

Heterogeneous paths for packagepath not supported.

It is not possible to register the same software package with the same name with different locations at different hosts; for example:

 hadbm registerpackage test --packagepath=/var/install1 --hosts europa11 Package successfully registered. hadbm registerpackage test --packagepath=/var/install2 --hosts europa12 hadbm:Error 22171: A software package has already been registered with the package name test.

Solution

HADB does not support heterogeneous paths across nodes in a database cluster. Make sure that the HADB server installation directory (--packagepath) is the same across all participating hosts.

6173886, 6253132

createdomain may fail.

If running the management agent on a host with multiple netwrok interfaces, the createdomain command may fail if not all network interfaces are on the same subnet:

 hadbm:Error 22020: The management agents could not establish a domain, please check that the hosts can communicate with UDP multicast.

The management agents will (if not configured otherwise) use the "first" interface for UDP multicasts ("first" as defined by the result from java.net.NetworkInterface.getNetworkInterfaces()).

Solution

The best solution is to tell the management agent which subnet to use (set ma.server.mainternal.interfaces in the configuration file, e.g., ma.server.mainternal.interfaces=10.11.100.0). Alternatively one may configure the router between the subnets to route multicast packets (the management agent uses multicast address 228.8.8.8).

Before retrying with a new configuration of the management agents, you may have to clean up the management agent repository. Stop all agents in the domain, and delete all files and directories in the repository directory (identified by repository.dr.path in the management agent configuration file). This must be done on all hosts before restarting the agents with a new configuration file.

6230792, 6230415

Starting, stopping, and reconfiguring HADB may fail or hang.

On Solaris 10 Opteron, starting, stopping or reconfiguring HADB using the hadbm command may fail or hang with one of the following errors:

 hadbm:Error 22009: The command issued had no progress in the last 300 seconds. HADB-E-21070: The operation did not complete within the time limit, but has not been cancelled and may complete at a later time.

This may happen if there are inconsistencies reading/writing to a file (nomandevice) which the clu_noman_srv process uses. This problem can be detected by looking for the following messages in the HADB history files:

 n:3 NSUP INF 2005-02-11 18:00:33.844 p:731 Child process noman3 733 does not respond. n:3 NSUP INF 2005-02-11 18:00:33.844 p:731 Have not heard from it in 104.537454 sec. n:3 NSUP INF 2005-02-11 18:00:33.844 p:731 Child process noman3 733 did not start.

Solution

The following workaround is unverified, as the problem has not been reproduced manually. However, running this command for the affected node should solve the problem.

 hadbm restartnode --level=clear nodeno dbname 

Note that all devices for the node will be reinitialized. You may have to stop the node before reinitializing it.

6232140

The management agent terminates with the exception "IPV6_MULTICAST_IF failed"

When starting on a host running Solaris 8 with several NIC cards installed, if there is a mixture of cards with IPv6 and IPv4 enabled, the management agent may terminate with the exception "IPV6_MULTICAST_IF failed."

Solution

Set the environment variable JAVA_OPTIONS to -Djava.net.preferIPv4Stack=true; for example:

 export JAVA_OPTIONS="-Djava.net.preferIPv4Stack=true"

Alternatively, use Solaris 9 or later, which do not exhibit this problem.

6249685

clu_trans_srv cannot be interrupted.

There is a bug in the 64-bit version of Red Hat Enterprise Linux 3.0 that makes the clu_trans_srv process end up in an uninterruptible mode when performing asynchronous I/O. This means that kill -9 does not work and the operating system must be rebooted.

Solution

Use a 32-bit version of Red Hat Enterprise Linux 3.0.

6262824

hadbm does not support passwords containing capital letters.

Capital letters in passwords are converted to lowercase when the password is stored in hadb.

Solution

Do not use passwords containing capital letters.

6265419

Downgrading from HADB Version 4.4.2.5 to HADB Version 4.4.1.7 causes ma to fail with different error codes.

When downgrading to a previous HADB version, the management agent may fail with different error codes.

Solution

It is possible to downgrade the HADB database, however the management agent cannot be downgraded if there changes have been made in the repository objects. After a downgrade, you must keep use the management agent from the latest HADB version.

6271063

Install/removal and symlink preservation.

Regarding install/removal of HADB c package (Solaris: SUNWhadbc, Linux: sun-hadb-c) version <m.n.u-p>, the symlink /opt/SUNWhadb/<m> is never touched once it exists. Thus, it is possible that an orphaned symlink will exist.

Solution

Delete the symlink before install or after uninstall unless in use.

6273681

Management agents in global and local zones may interfere.

On Solaris 10, stopping a management agent by using the ma-initd script in a global zone stops the management agent in the local zone as well.

Solution

Do not install the management agent both in the global and local zone.

6275103

hadbm/ma should give a better error message when a session object has timed out and deleted at MA.

Sometimes, a resource contention problem on the server may cause a management client to become disconnected, When reconnecting, a misleading error message "hadbm:Error 22184: A password is required to connect to the management agent" may be returned.

Solution

Check if there is a resource problem on the server, take proper action (e.g., add more resources), and retry the operation.

6275319

Non-root users cannot manage HADB.

Installing with Java Enterprise System (as root) does not permit non-root users to manage HADB.

Solution

Always login as root to manage HADB.

6293912

The Management Agent should not use special-use interfaces.

Special use interfaces with IP addresses like 0.0.0.0 should not be registered as valid interfaces to be used for HADB nodes in the Management Agent. Registering such interfaces may cause problems if HADB nodes are set up on these interfaces by means of a user issuing a hadbm create command using host names instead of IP addresses. The nodes will then be unable to communicate, causing the create command to hang.

Solution

When using hadbm create on hosts with multiple interfaces, always specify the IP addresses explicitly using DDN notation.

6291562

Reassembly failures on Windows.

On the Windows platform, with certain configurations and loads, there may be a large number of reassembly failures in the operating system. The problem has been seen with configurations of more than twenty nodes when running several table scans (select *) in parallel. The symptoms may be that transactions abort frequently, repair or recovery may take a long time to complete, and there may be frequent timeouts in various parts of the system.

Solution

To fix the problem, the Windows registry variable HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters can be set to a value higher than the default 100. It is recommended that you increase this value to 0x1000 (4096). For more information, see. article 811003 from the Microsoft support pages.

# Installation

This section describes known installation issues and associated solutions.

Bug ID

Summary

5009728

Installation shutdown hanging on some Linux systems after clicking the "Finish" button.

This problem has been observed on several Linux systems. It is most common on Java Desktop System 2 but has also been observed on Linux Red Hat distributions.

After clicking the "Finish" button on the last installer screen, the installer fails to launch a browser window containing the product About page or product registration page, and hangs indefinitely, not returning the command prompt.

Solution

Exit the installer by pressing Ctrl+C in the terminal window in which the installer was started. After doing this, browser window containing product About page or registration page will sometimes be launched, but if it does not show up, start the browser and enter following URL in order to review About page:

 file://install_dir/docs-ee/about.html

If you also selected the installation option to register the product, follow the link to registration page available on product About page.

6199697

On Windows, the imq directory needs to be created during installation.

On Windows, immediately after installing Application Server Enterprise Edition, the Message Queue broker fails on startup with a message saying the directory drive:\as\domains\domain1\imq does not exist.

Note that if the broker is started after starting domain1, the directory will be created by the Application Server and the problem will not occur.

Solution

1. Create the var_home_dir_location before creating the broker:

 $imqbrokerd -varhome var_home_dir_location  For example:  $imqbrokerd -varhome D:\as\domains\domain1\imq

6297837

The Application Server installer shows the wrong product release date in the product name, “Sun Java(TM) System Application Server Enterprise Edition 8.1 2005Q4.”

Solution

The correct product name/date should read “Sun Java(TM) System Application Server Enterprise Edition 8.1 2005Q2.”

# J2EE Tutorial

To run the J2EE 1.4 Tutorial on the Sun Java System Application Server Enterprise Edition 8.2 perform these tasks:

• When you edit the file examples/common/build.properties as described in the “About the Examples” section of the “About this Tutorial” chapter, also change port 4848 to 4849.

• When using Deploytool, add the server localhost:4849 before deploying an example.

• When using the Administration Console to create any resource, use the Targets tab to specify the server as the target. If you use the command line or an asant target, the server is the default target, no further action is required.

# Lifecycle Management

This section describes known lifecycle management issues and associated solutions.

Bug ID

Summary

6193449

After setting the ejb-timer-service property minimum-delivery-interval to 9000, an attempt to set the ejb-timer-service property redelivery-interval-in-mills to 7000 causes the set command to fail with the following error:

 [echo] Doing admin task set [exec] [Attribute(id=redelivery-interval-internal-in-millis) : Redelivery-Interval (7,000) should be greater than or equal to Minimum-delivery-interval-in-millis (9,000)] [exec] CLI137 Command set failed.
• minimum-delivery-interval is the minimal interval duration between deliveries of the same periodic timer.

• redelivery-interval-in-mills is the time the timer service will wait after a failed ejbTimeout before attempting redelivery.

The problem is that the logic that relates the redelivery interval property to the minimum delivery property is incorrect and prevents you from using the GUI or the CLI to set any value where the minimum delivery interval is greater than redelivery interval.

The minimum-delivery-interval-in-millis must always be set equal to or higher than ejb-timer-service property redelivery-interval-in-millis. The problem is that there is an erroneous validation check in the Application Server to verify that the value for redelivery-interval-in-millis is greater than the value for minimum-delivery-interval-in-millis.

Solution

Use the default values for these properties, as follows:

 minimum-delivery-interval(default)=7000 redelivery-interval-in-millis(default)=5000

Values other than these defaults will generate an error.

# Logging

This section describes known logging issues and solutions.

Bug ID

Summary

6180095

Setting debug statement for access,failure causes hanging in Application Server startup.

Setting the java.security.debug option for the JVM will cause the server instance startup to freeze with a deadlock; for example, setting the following in domain.xml causes the problem:

 -Djava.security.debug=access,failure

None at this time. Please avoid setting this flag.

# Message Queue

This section describes known Java message queue issues and associated solutions.

6173308, 6189645, 6198481, 6199510, 6208728

JMS reconnection does not successfully complete in certain cases that are timing dependent.

Failures to reconnect in timing-dependent scenarios can be caused by several problems.

Solution

You can work around these problems by:

• Restarting the brokers involved

• Restarting the Application Server instances involved

6198465

Asynchronous message listener behavior changed in appclient from 8.0 to 8.1 Update 2.

Due to a recent change, when an asynchronous message listener is the only live thread in the app-client container, the remaining appclient virtual machine exists as a daemon. This behavior is a regression for past applications that perform asynchronous receives in ACC. This problem affects application clients that set a JMS message listener and exit the main thread.

Solution

Do not exit the main thread. Wait for the message listener to notify the main thread before terminating the main thread.

# Monitoring

This section describes known monitoring issues and associated solutions.

Bug ID

Summary

6174518

Some of the HTTP Service monitoring statistics do not present useful information and should be ignored.

When viewing the monitoring statistics of some elements of the HTTP Service, some values presented do not correspond to current values or are always 0. Specifically, the following HTTP Service statistics do not present information applicable to the Application Server, and should be ignored:

• http-service

rateBytesTransmitted

• pwc-thread-pool (the element)

Solution

These monitors will be removed in future releases and replaced with more appropriate information.

6191092

Monitoring MBean for an undeployed EJB module is not removed, even though all statistics under that monitoring name are moved.

For example:

 EJBModuleMonitorMap().size() = 1 eventhough ejb module is undeployed EJBModuleMonitor().getName() = sqe_ejb_s1_01

This true for both EJB modules and applications. Both programmatically (through MBean API) and through asadmin list/get, an empty monitoring MBean still exists.

Diagnostics

 asadmin list -m "server.applications" shows the following output: server.applications.MEjbApp server.applications.__ejb_container_timer_app server.applications.adminapp server.applications.admingui server.applications.com_sun_web_ui server.applications._export_install_nov-11_domains_domain1_applications _j2ee-modules_sqe_ejb_s1_01

You can look at statistics:

 bin/asadmin list -m "server.applications._export_install_nov-11_ domains_domain1_applications_j2ee-modules_sqe_ejb_s1_01" server.applications._export_install_nov-11_domains_domain1_ applications_j2ee-modules_sqe_ejb_s1_01.SQEMessageserver. applications._export_install_nov-11_domains_domain1_applications_ j2ee-modules_sqe_ejb_s1_01.TheGreeter

Once you undeploy:

 _export_install_nov-11_domains_domain1_applications_j2ee-modules_ sqe_ejb_s1_01

If you do a list command, you still see the application:

but it does not contain any monitoring statistics:

 asadmin list -m "server.applications._expo rt_install_nov-11_domains_domain1_applications_j2ee-modules_ sqe_ejb_s1_01" Nothing to list at server.applications.-export-install-nov- 11-domains-domain1-applications-j2ee-modules-sqe-ejb-s1-01.

To get the valid names beginning with a string, use the wildcard (*') character. For example, to list the names of all the monitorable entities that begin with server, use list "server.*".

Solution

This is harmless. Module can be safely redeployed with out any problems. The root monitoring Mbean is not removed, but it is empty.

# PointBase

Bug ID

Summary

6184797

Setting the isolation levels on a connection pool for an application causes exceptions in PointBase.

For a JDBC connection pool pointing to a PointBase database installation, setting the transaction-isolation-level pool attribute to any value other than the default (Connection.TRANSACTION_READ_COMMITTED) causes an exception. However, setting this same parameter to non-default values for pools pointing to other databases does not throw an exception.

Solution

For a JDBC connection pool pointing to a PointBase database installation, do not attempt to set the transaction-isolation-level.

6204925

PointBase throws an exception if a network server and embedded drivers are used together.

The bundled PointBase sometimes throws an exception if the network server driver and the embedded driver are simultaneously used.

Solution

Use either the embedded driver or the network server driver, but not both.

Upgrade problem where the default PointBase database is overwritten.

When upgrading to Application Server Enterprise Edition 8.2 , the Update release patch overwrites the Pointbase default database.

Solution

Recreate or re-enter any scheme or data that existed prior to the upgrade. If you deployed applications with CMP beans with the generate table option, you must undeploy or redeploy the application to have the tables regenerated.

On Windows, setup-one-machine-cluster hangs but works on Solaris; mqfailover requires Ctrl+C to cancel and then must be re-run.

From install_dir\samples\ee-samples\failover\apps\mqfailover\docs\index.html, if you run the following commands:

• Console 1

 cd install_dir\samples\ee-samples asant start-mq-master-broker1
• Console 2

 cd install_dir\samples\ee-samples asant start-mq-cluster-broker1
• Console 3

 cd install_dir\samples\ee-samples asant start-mq-cluster-broker2
• Console 4

 cd install_dir\samples\ee-samples asadmin start-domain domain1

If you have already executed asant setup-one-machine-cluster-without-ha or asant setup-one-machine-cluster-with-ha for any other Enterprise Edition sample, then execute asant configure-mq otherwise execute asant setup-one-machine-cluster-and-configure-mq. In this case, the command appears to succeed:

 start_nodeagent: [echo] Start the node agent cluster1-nodeagent [exec] Command start-node-agent executed successfully.

But then the system hangs indefinitely.

Solution

None at this time. This problem similarly affects all Enterprise Edition samples that use this ant target on Windows. A workaround is to Ctrl+C out of the hung process and then rerun it.

Documentation does not explicitly state that you need to create JMS resources before running the MQ Failover Sample Application following the asadmin deploy instructions.

The error thrown is as follows:

 /opt/SUNWappserver/domains/domain1/config/sun-acc.xml -name MQFailoverTestClient -textauth -user j2ee -password j2ee Nov 18, 2004 10:50:17 PM com.sun.enterprise.naming.NamingManagerImpl bindObjects SEVERE: NAM0006: JMS Destination object not found: jms/durable/TopicA Nov 18, 2004 10:50:18 PM com.sun.enterprise.naming.NamingManagerImpl bindObjects SEVERE: javax.naming.NameNotFoundException javax.naming.NameNotFoundException

The documentation does not explicitly state that JMS resources must be manually created if manual deployment is done using asadmin deploy commands, and that the provided ant targets to deploy the sample application should be used.

Solution

Use the asant deploy target for the build.xml script, which creates the required JMS resources to run the application.

On Linux, a runtime error is displayed during certificate creation in web services/security samples.

When deploying the install_dir/samples/webservices/security sample (basicSSl) on Linux, the certificate is not created and an error similar to the following is thrown:

 generate_certs: [echo] ***Exporting certificate from NSS database [exec] Result: 1 [echo] ***Generating Java Keystore from generated certificate [exec] keytool error: java.lang.Exception: Input not an X.509 certificate [exec] Result: 1 [echo] ***Generating Java trust store from generated certificate [exec] keytool error: java.lang.Exception: Input not an X.509 certificate [exec] Result: 1 . . . generate_certs: [echo] ***Exporting server certificate from NSS database to a PKCS12 certificate file [exec] /opt/sun/appserver/lib/pk12util: /usr/lib/libnss3.so: version NSS_3.9' not found (required by /opt/sun/appserver/lib/pk12util) [exec] /opt/sun/appserver/lib/pk12util: /usr/lib/libnss3.so: version NSS_3.6' not found (required by /opt/sun/appserver/lib/pk12util) [exec] /opt/sun/appserver/lib/pk12util: /usr/lib/libnss3.so: version NSS_3.7' not found (required by /opt/sun/appserver/lib/pk12util) [exec] Result: 1

The problem is that NSS libraries are in different locations on Linux installations than on Solaris installations. You need to make sure that the LD_LIBRARY_PATH points to the proper NSS libraries when deploying on Linux. Either set LD_LIBRARY_PATH in your environment, or set it in the install_dir/bin/asant shell wrapper script.

Solution

Do one of the following:

• Set LD_LIBRARY_PATH=/opt/sun/private/lib.

• Add to the following line to the install_dir/bin/asant script:

 LD_LIBRARY_PATH=$AS_NSS:$LD_LIBRARY_PATH;export LD_LIBRARY_PATH

Cannot run WebServiceSecurity applications on Enterprise Edition with J2SE 5.0.

WebServiceSecurity applications cannot run with J2SE 5.0 because:

• J2SE 5.0 PKCS11 does not support UNWRAP mode

• J2SE 5.0 PKCS11 does not support RSA/ECB/OAEPWithSHA1AndMGF1Padding with PKCS11

The J2SE team has filed "CR 6190389: Add support for the RSA-PKCS1 and RSA-OAEP wrap/unwrap mechanisms" for this bug.

Solution

Use J2SE 1.4.2 with any other JCE provider (not the one included by default). Note that hardware accelerator support will not be present in this configuration.

Domains created in custom-path other than install_dir/domains directory are not upgraded directly while upgrading from Application Server Enterprise Edition 8 to Application Server Enterprise Edition 8.1.

When running the Upgrade Utility and identifying the install_dir as the source installation directory, the upgrade process upgrades only those domains that are created under install_dir/domains directory. Domains created in other locations are not upgraded.

Solution

Before starting the upgrade process, copy all the domain directories from their different locations to the install_dir/domains directory.

On some Linux systems, the installer running "Upgrade in place" fails to start upgrade tool after clicking on the "Start Upgrade Wizard" button.

This problem has been observed on several Linux systems, it is most common on Java Desktop System 2 but has also been observed on Red Hat distributions.

After clicking the "Start Upgrade Tool" button on the final installer screen, the installer fails to launch the upgrade tool to complete the upgrade process, and hangs indefinitely, not returning the command prompt.

Solution

This issue is not encountered if command line installation mode is used to run upgrade in place.

1. If you ran upgrade in place in GUI mode and encountered this problem, exit the installer by pressing Ctrl+C in the terminal window in which the installer was started.

2. Start upgrade tool from the terminal window, using following command:

 install_dir/bin/asupgrade --source install_dir/domains --target install_dir --adminuser adminuser --adminpassword adminpassword --masterpassword changeit

adminuser and adminpassword should match the values used for the installation you are upgrading.

3. When the upgrade tool completes the upgrade process you can also start the browser and enter following URL in order to review About page:

 file://install_dir/docs-ee/about.html

If you also selected the installation option to register the product, follow the link to registration page available on product About page.

On Windows, deploying an application using --precompilejsp=true can lock JAR files in the application, causing later undeployment or redeployment to fail.

If you request precompilation of JSPs when you deploy an application on Windows, later attempts to undeploy that application or to redeploy it (or any application with the same module ID) will not work as expected. The problem is that JSP precompilation opens JAR files in your application but does not close them, and Windows prevents the undeployment from deleting those files or the redeployment from overwriting them.

Note that undeployment succeeds to a point, in that the application is logically removed from the Application Server. Also note that no error message is returned by the asadmin utility, but the application's directory and the locked jar files remain on the server. The server's log file will contain messages describing the failure to delete the files and the application's directory.

Attempts to redeploy the application after undeploying fail because the server tries to remove the existing files and directory, and these attempts also fail. This can happen if you try to deploy any application that uses the same module ID as the originally deployed application, because the server uses the module ID in choosing a directory name to hold the application's files.

Attempts to redeploy the application without undeploying it first will fail for the same reasons.

Diagnostics

If you attempt to redeploy the application or deploy it after undeploying it, the asadmin utility returns an error similar to the one below.

 An exception occurred while running the command. The exception message is: CLI171 Command deploy failed : Deploying application in domain failed; Cannot deploy. Module directory is locked and can't be deleted.

Solution

If you specify --precompilejsps=false (the default setting) when you deploy an application, then this problem will not occur. Be aware that the first use of the application will trigger the JSP compilation, so the response time to the first request will be longer than for later requests.

Note also that if you do precompile, you should stop and restart the server before undeploying or redeploying the application. The shutdown frees the locked JAR files so the undeployment or redeployment after the restart can succeed.

Unable to deploy WAR with Servlet 2.4-based web.xml that contains an empty <load-on-startup> element.

The optional load-on-startup servlet element in a web.xml indicates that the associated servlet is to be loaded and initialized as part of the startup of the web application that declares it.

The optional content of this element is an integer indicating the order in which the servlet is to be loaded and initialized with respect to the web application's other servlets. An empty <load-on-startup> indicates that the order is irrelevant, as long as the servlet is loaded and initialized during the startup of its containing web application.

The Servlet 2.4 schema for web.xml no longer supports an empty <load-on-startup>, meaning that an integer must be specified when using a Servlet 2.4 based web.xml. If specifying an empty <load-on-startup>, as in <load-on-startup/>, the web.xml will fail validation against the Servlet 2.4 schema for web.xml, causing deployment of the web application to fail.

Backwards compatibility issue. Specifying an empty <load-on-startup> still works with Servlet 2.3 based web.xml.

Solution

Specify <load-on-startup>0</load-on-startup> when using a Servlet 2.4 based web.xml to indicate that servlet load order does not matter.

Unable to compile JSP page on resource constrained servers.

The JSP page is accessed but fails to compile, and the server log contains the error message "Unable to execute command" with the following stack trace:

Javac.compile(Javac.java:842) at org.apache.tools.ant.taskdefs.Javac. execute(Javac.java:682) at org.apache.jasper.compiler.Compiler. generateClass(Compiler.java:396) Solution Set the JSP compilation switch "fork" to "false." This can be done either of two ways: • Globally, by setting the fork init parameter of the JspServlet in${S1AS_HOME}/domains/domain1/config/default-web.xml to false:

  jsp org.apache.jasper.servlet.JspServlet .... fork false .... 
• On a per-web application basis, by setting the fork JSP configuration property in sun-web.xml to false:

  

Either setting will prevent ant from spawning a new process for javac compilation.

Application Server does not support auth-passthrough Web Server 6.1 Add-On.

The Sun Java System Application Server Enterprise Edition 8.2 adds support for the functionality provided by the auth-passthrough plugin function available with Sun Java System Application Server Enterprise Edition 7.1. However, in Application Server Enterprise Edition 8.2 , the auth-passthrough plugin feature is configured differently.

The auth-passthrough plugin function in Application Server Enterprise Edition 7.1 has been useful in two-tier deployment scenarios, where:

• Application Server instance is protected by a second firewall behind the corporate firewall.

• No client connections are permitted directly to the Application Server instance.

In such network architectures, a client connects to a front-end web server, which has been configured with the service-passthrough plugin function and forwards HTTP requests to the proxied Application Server instance for processing. The Application Server instance can only receive requests from the web server proxy, but never directly from any client hosts. As a result of this, any applications deployed on the proxied Application Server instance that query for client information, such as the client's IP address, will receive the proxy host IP, since that is the actual originating host of the relayed request.

In Application Server Enterprise Edition 7.1, the auth-passthrough plugin function could be configured on the proxied Application Server instance in order to make the remote client's information directly available to any applications deployed on it; as if the proxied Application Server instance had received the request directly, instead of via an intermediate web server running the service-passthrough plugin.

In Application Server Enterprise Edition 8.2 , the auth-passthrough feature may be enabled by setting the authPassthroughEnabled property of the <http-service> element in domain.xml to TRUE, as follows:

 

The same security considerations of the auth-passthrough plugin function in Application Server Enterprise Edition 7.1 also apply to the authPassthroughEnabled property in Application Server Enterprise Edition 8.2 . Since authPassthroughEnabled makes it possible to override information that may be used for authentication purposes (such as the IP address from which the request originated, or the SSL client certificate), it is essential that only trusted clients or servers be allowed to connect to an Application Server Enterprise Edition 8.2 instance with authPassthroughEnabled set to TRUE. As a precautionary measure, it is recommended that only servers behind the corporate firewall should be configured with authPassthroughEnabled set to TRUE. A server that is accessible through the Internet must never be configured with authPassthroughEnabled set to TRUE.

Notice that in the scenario where a proxy web server has been configured with the service-passthrough plugin and forwards requests to an Application Server 8.1 Update 2 instance with authPassthroughEnabled set to TRUE, SSL client authentication may be enabled on the web server proxy, and disabled on the proxied Application Server 8.1 Update 2 instance. In this case, the proxied Application Server 8.1 Update 2 instance will still treat the request as though it was authenticated via SSL, and provide the client's SSL certificate to any deployed applications requesting it.
