Error description New FunctionLocal fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V4.0.1 for z/OS and OS/390 * **************************************************************** * PROBLEM DESCRIPTION: APAR PQ65206 addresses various problems * * in WebSphere Application Server * * V4.0.1 for z/OS and OS/390. * **************************************************************** * RECOMMENDATION: * **************************************************************** The following problems are addressed in APAR PQ65206: (MD13496) JDBC Connections and their associated prepared statements should be cached to improve performance. (MD14130) Support is needed to allow clients to pass a client certificate on the SSL connection to the HTTP Transport. (MD14131) Support is needed which provides additional security/verification on HTTP SSL Transport connections. This support should enforce that all SSL connections have a client certificate and the user ID associated with that client certificate has a certain SAF authority. (MD14132) Support is needed which provides request level WLM classification for HTTP Transport requests. This support should allow the mapping of each HTTP request based on Host and/or URI to a WLM Transaction Class. (MD14133) Support is needed which provides request level network connection management capability by interacting with the Network QoS Policy support. This should provide request level data to TCP/IP for input to be used to map to the Network QoS Policy. (MD14350) Applications that use DriverManager to obtain JDBC connections instead of the preferred res-ref declaration and java:comp lookup are not able to get any management of those connections. Without management, it is possible for applications to leak the valuable connections. . (MD14535) Abend0c4 rc11 (rsncode=11) in IRRRIU00 in loadmod IRRRFR10 occurs in WebSphere application server server region. The following messages can also appear in the application server server region: ICH409I 0C4-011 ABEND DURING IRRSIU00 PROCESSING. ICH409I 0C4-011 ABEND DURING IRRSDU00 PROCESSING. followed by an svc dump in csect IRRRDU00 with abend0C4-011. This problem can also surface as ICH409I 378-010 ABEND DURING IRRSDU00 PROCESSING. followed by an svc dump with abend378 rsncode=10 in IRRRDU00 . ACEE's are being re-used before being freed, resulting in 378 abend. IRRSIA00 was being invoked with the RACF managed ACEE option enabled. This caused RACF to distribute the save ACEE to multiple threads. BPX1TLS is called to affix the ACEE to the thread. This call frees the USP (USS chunk of the ACEE) and recreates a new one. The 378 abend is caused by 2 threads trying to free the same USP. . A temporary workaround is to uncheck the check box for "Enable Setting OS Thread Identity to RunAS" in the Administration Application (SM EUI) for the J2EE server experiencing the abend. Depending on the application, RunAs may be a required setting and this workaround may not be viable for a particular application and thus for its server. (WS13531) There is an increasing requirement to keep track of principals used to authenticate users. Principals from non-SAF registries are mapped to MVS userids, which are tracked through SMF, but these other principals should also be kept track of, including EJB Role names, Kerberos principals, etc. This function needs to be added to the WebSphere for z/OS product. (WS13685) Support is needed for CMP inheritance. Providing this support will make the WebSphere for z/OS product compatible with the CMP inheritance provided by WebSphere AE and will enhance the portability of applications, making use of CMP inheritance, from the WebSphere AE platform to the z/OS platform. (WS13953) Currently in WebSphere Application Server V4.0.1 for z/OS and OS/390, there is no mechanism to allow users to scriptify their J2EE applications for resolve processing and other 390 specific operations. A tool should be delivered which provides such functionality for users to optionally bypass AAT usage if J2EE application is already properly constructed by other application assembly tooling, as well as providing scripting functionality support to resolve a J2EE application without using System Management End User Interface (Administration application), also known as the SM EUI. (WS13954) Support is needed which allows the installation of EAR files with the System Management End User Interface (Administration application), also known as the SM EUI, coming directly out of WSAD. (WS14109.01) Support is needed for deploying applications developed from within WebSphere Application Developer Integration Edition (WSADIE) using the CICS or IMS J2EE Connectors, and running these applications on the WebSphere for z/OS platform. (WS14136) There is a difference between the default visibility mode in WebSphere AE and the default delegation mode in WebSphere Application Server V4.0.1 for z/OS and OS/390. The default mode for WebSphere AE is "Application Mode" while in the WebSphere for z/OS and OS/390 product it is "Compatibility Mode". WebSphere Application Server V4.0.1 for z/OS and OS/390 should be modified to be compatible with WebSphere AE. (WS14137) When ClassLoader errors occur, they are difficult to analyze by customers. Often the customer needed to turn on traci to detect them. Additional diagnostics are needed in the ClassLoader to enhance the serviceabiltiy of the WebSphere for z/OS product. (WS14153) Dynamic control of tracing is needed to enable debug o problems without recycling the server. (WS14230) This APAR delivers enhanced support for WebSphere DB2 datasource definitions.Problem conclusion Temporary fix Comments APAR PQ65206 provides the following problem resolution: (MD13496) WebSphere Container Managed Persistence (CMP) Connection Pooling has been provided in the APAR. This support aids in the management of CMP Bean performance. It does so by caching and reusing both JDBC connections and prepared statements, using a two-tier structure that pools prepared statements with their corresponding connections. This support runs in either of two selectable modes: within transaction or across transactions. (MD14130) Support for client certificate capability to the HTTP SSL Tranport support has been added to the WebSphere for z/OS product. This support allows clients to pass a client certificate on the SSL connection to the HTTP Transport. (MD14131) Support has been provided for an additional level of security/verification on HTTP SSL Transport connections. This support will enforce that all SSL connections have a client certificate and the user ID associated with that client certificate has a certain SAF authority. (MD14132) Support has been provided for request level WLM classification for HTTP Transport requests. This enhancement allows the mapping of each HTTP request based on Host and/or URI to a WLM Transaction Class. The mapping capability is accomplished with a new configuration file. (MD14133) Support has been provided for request level network connection management capability by interacting with the Network QoS Policy support. This support provides request level data to TCP/IP for input to be used to map to the Network QoS Policy. (MD14350) A java.sql.Driver provided by WebSphere is now registered with the JDBC DriverManager. This WebSphere JDBC Driver will forward requests for connections to a DB2 DataSource managed by WebSphere. This will allow connection management to interpose their wrappers. (MD14535) Remove the RACF managed ACEE option on the application server region IRRSIA00 calls. . (WS13531) Support was added to record the original authenticated identity in the X500NAME field of the ACEE, along with a "service name" indicating the authentication mechanism. This information will be included in any future SMF records that may be cut for this user. Code was also added to the EJB Role authorization checks to enable SMF records to be cut for every authorization check (once for a list of roles). This enables control of auditing EJB role authorizations in SMF. (WS13685) This APAR delivers support for CMP inheritance. Providing this support makes the WebSphere for z/OS product compatible with the CMP inheritance provided by WebSphere AE and will enhance the portability of applications, making use of CMP inheritance, from the WebSphere AE platform to the z/OS platform. (WS13953) A Direct Deployment tool has been provided which contains scripting functionality for the deployment process of WebApps as well as J2EE ear files. This tool will provide such functionality for users to optionally bypass AAT usage if J2EE application is already properly constructed by other application assembly tooling, as well as providing scriptified ways to build resolve a J2EE application without using SM EUI. (WS13954) Support has been provided which allows the installation of EAR files with the the System Management End User Interface (Administration application), also known as the SM EUI, coming directly out of WSAD. (WS14109.01) Support has been provided for deploying applications developed from within WebSphere Application Developer Integration Edition (WSADIE) using the CICS or IMS J2EE Connectors, and running these applications on the WS/390 platform. This allows developers using WSADIE to develop J2EE application components which access back-end resources such as CICS or IMS transactions. Please note that applications which are developed using the Service Flow tooling within WSADIE are not supported and thus are not guaranteed to run on the WS/390 platform. In other words, only simple services consisting of one interaction with a back-end resource such as a CICS or IMS transaction are supported on the WS/390 platform, while composite services composed using the Service Flow tooling are not supported. Users of the IMS Connector for Java will need to install IMS Connect APAR PQ65982 in order to run applications which are developed within WSADIE using IMS Connector for Java. (WS14136) In order to enhance the portability of WebSphere AE applications to WebSphere for z/OS and OS/390, the default delegation mode was changed to "Application Mode", making it equivalent with WebSphere AE. (WS14137) Additional diagnostic messages have been provided for detecting ClassLoader problems. Audit messages will be issued that provide actual information about the problem cause. These will allow for quick ClassLoader problem resolution and therefore improved service. (WS14153) Dynamic control of tracing has been provided via the modify command. (WS14230) This APAR delivers enhanced support for WebSphere DB2 datasource definitions. Through the System Management End User Interface (Administration application), also known as the SM EUI, you can specify an optional SQLID value. This SQLID value is then used to resolve unqualified table references for SQL statements executed on connections acquired from that datasource. APAR PQ65206 is associated with SERVICE LEVEL W401400 of WebSphere Application Server V4.0.1 for z/OS and OS/390.
