Refer to Oracle Database Installation Guide for IBM z/OS on System z to determine the total Oracle non-database disk space requirements, including those for code, JCL, and samples.
This release of Oracle Database 10g for IBM z/OS on System z does not include support for the following features and functions.

The following is a list of known restrictions to this release of Oracle Database on IBM z/OS on System z:
Non-repudiation of Advance Queuing messages sent across a firewall using Internet Document Access Protocol (IDAP) is not supported in this release.
Oracle database files on IBM z/OS on System z are implemented as VSAM linear data sets. IBM does not provide a space release function for VSAM data sets, so using ALTER DATABASE...RESIZE to make a database file smaller has no effect. Database files can be resized larger, both manually by using the
ALTER command and automatically as they fill (when a tablespace is defined with
No support is available currently for automatically recalling IBM z/OS on System z data sets that are used by the Oracle server if they have been migrated to other media by IBM's DFSMShsm, or a similar product. This applies to the VSAM linear data sets (LDS) comprising the database, and to non-VSAM data sets such as parameter files. All such data sets must be on disk in their original form when they are opened by the server.
To use 10g Release 2 (10.2.0.5) Client with a C program, you must complete the following steps:
Ensure that the C for z/OS V1R2 compiler is installed, instead of or addition to the C for OS390 V2R10.
Recompile all OCI programs using the C for z/OS V1R2 compiler with the ENUM(INT) option.
Note:Refer to z/OS V1R2.0 C/C++ Compiler and Run-Time Migration Guide for additional information about this issue.
The following is a list of restrictions that apply to the IEEE standard floating point numbers:
BINARY_FLOAT database data types are not supported for client applications running on z/OS.
This restriction applies to both customer-written applications and Oracle tools and utilities on z/OS. Attempts to store or fetch these types from a client program running on z/OS produces unpredictable results with both local and remote Oracle10g servers.
Use of z/Architecture Binary Floating Point (BFP, also known as IEEE 754 floating point) in Oracle applications running on z/OS is not supported.
This restriction means that customer-written Oracle applications cannot bind or define host variables that are BFP types in an Oracle SQL statement. This restriction also affects tools and utilities: both SQL*Loader and the server External Table feature cannot load file data that is BFP.
Traditional System/370 floating point data (now known as Hexadecimal Floating Point or HFP) remain supported, as in the past.
The following java methods are not supported with the JavaVM:
Native compilation of Java or PL/SQL programs is not supported.
Oracle Datapump is restricted to HFS and zFS file systems.
The following sections contain issues that affect Oracle Enterprise Manager Intelligent Agent:
OracleDatabase 10g for IBM z/OS on System z supports only a minimal set of system statistics and these may not reflect the actual performance of the system.
Configuration of the Agent must be done manually. The Oracle Enterprise Manager Configuration Assistant is not supported with this release.
OracleDatabase 10g for IBM z/OS on System z supports database startup and shutdown from the console. Before you use this feature, ensure that the OSDI rdbms and net subsystem are active.
OracleDatabase 10g for IBM z/OS on System z does not support the iSQL*Plus interface from the console.
Currently, OracleDatabase 10g for IBM z/OS on System z only ships with the Oracle Enterprise Manager Agent. Oracle Enterprise Manager Grid Control Console is not supported, though this release supports a remote Oracle Enterprise Manager Grid Control Console. This is because the repository for this console must not reside on a z/OS platform.
External Tables is an Oracle feature that enables you to process non-Oracle operating system files as Oracle database tables. On IBM z/OS on System z, the External Tables feature is limited to accessing files in the HFS and zFS file systems.
Oracle JDBC OCI drivers are supported for a limited subset of features. When you use a feature that is not supported, an error is returned with a message displayed to state that the feature is not supported. The Database character set must be WE8EBCDIC1047 or similar.
The following sections contain issues affecting Oracle OLAP:
The Oracle OLAP API interface is not supported.
Dynamically linking options into the Oracle kernel as part of the Oracle Universal Installer installation is not supported in this release. If you choose the OLAP optional feature, then after the Oracle Universal Installer installation is complete, you must complete the following task manually to link the required code into Oracle:
Do this by running the
ENV file in your
ORACLE_HOME location. For example:
cd $ORACLE_HOME/server/rdbms make -f ins_rdbms.mk olap_on make -f ins_rdbms.mk ioracle
A backup copy of the oracle executable is kept automatically in
$ORACLE_HOME/server/rdbms/bin. It is named
(Optional) Allocate a temporary
AUTHLOAD to hold the new Oracle executable.
The final stage of the relink make attempts to copy the new Oracle executable into your
AUTHLOAD, provided the link is successful. To allocate a temporary
Allocate your new
AUTHLOAD, using the same attributes as the current
ORACLE_HLQ_PDS environment variable to point to this new HLQ.
Refer to the Oracle OLAP documentation to run the OLAP installation scripts.
At a minimum, you must run the script
External jobs are not supported from Oracle Scheduler on IBM z/OS on System z.
If you use
ARCHIVE mode with Oracle Real Application Clusters (Oracle RAC), then you must either set the
LOG_ARCHIVE_FORMAT/DEST values, or ensure that each instance within the Oracle Real Application Clusters cluster is in a separate subsystem and uses the same OSDI service name for each instance. Failure to do so causes database recovery to fail, due to an inability to find archive log files.
For Oracle Security Server, an Oracle10g server or client on IBM z/OS on System z cannot be a participant in an Oracle security connection. However, an Oracle database server on IBM z/OS on System z can be the security repository.
SDO_GEORASTER feature is not supported.
DBMS_FILE_TRANSFER PL/SQL package is not supported.
The following configuration assistants for Oracle Universal Installer are not supported:
Database Configuration Assistant (DBCA)
Enterprise Manager Configuration Assistant (EMCA)
The utilities Oracle Trace and
dbnewid are not available.
Additional utilities are also not available with this release. For a complete list of unavailable utilities, refer to the documents Oracle Database Installation Guide for IBM z/OS on System z and Oracle Database System Administration Guide for IBM z/OS on System z.
The following parts of the XML Developers Kit are not supported:
XML Class Generator for Java and C++
Propagation from object queues with BFILEs is not supported in Oracle Database 10g.
When running SQL*Plus, if the
linesize variable exceeds the SPOOL data set record length, the record truncates, and you may receive the following error:
SP2-0308: cannot close spool file.
To work around this problem, ensure that the SQL*Plus
linesize variable is less than or equal to the SPOOL data set record length.
This issue is tracked with Oracle bug 4564229.
If you upgrade an Oracle9i database to Oracle Database 10g Release 1, Oracle Flashback features using a timestamp may fail. To work around this problem, enter the following SQL script from the Oracle Database 10g database:
SQL> DELETE FROM smon_scn_time WHERE orig_thread <> 0; SQL> COMMIT;
This issue is tracked with Oracle bug 3994270.
The following XML DB components are not supported in this release:
