An Oracle Alert Note 207319.1 has been issued :
Connections from Oracle 9.2 to Oracle7 are Not Supported This alert documents a restriction introduced in Oracle 9.2.0.1 which was omitted from the shipped documentation / README files. Versions Affected Oracle9i Release 2 (9.2.0.1) onwards is affected. Platforms Affected GENERIC , all platforms are affected Description Contrary to references in the documentation which may indicate otherwise connections from an Oracle 9.2 client to any Oracle7 database are NOT supported. This includes any form of Oracle 9.2 client such as: Client code statically linked with Oracle 9.2 client libraries Dynamically linked client code which uses Oracle 9.2 shared client libraries Database link connections from Oracle 9.2 to any Oracle7 database or gateway This alert is to warn customers of this restriction. Oracle 9.2 does not report an error at connect time but subsequent operations may fail with unexpected errors or dumps. Likelihood of Occurrence The likelihood of hitting problems depend on the operation being attempted. Possible Symptoms There are numerous symptoms which can occur when making a connection from an Oracle 9.2 client to an Oracle7 database. Some of these are shown below in order to aid rediscovery of this restriction. SQLPLUS / SQLPLUSW connections may dump / Dr Watson with a call stack like this: ttccfpg ttcfour ttcdrv nioqwa xaolog upirtr kpudbcx kpuexInitStmh kpuexec OCIStmtExecute Client SELECT operations may fail with errors such as: ORA-1002 Fetch out of sequence Operations over database links may fail with errors such as ORA-2063 / ORA-1002 Fetch out of sequence ORA-600 [qerrmOFBu1], [1003] Workaround There is no workaround as this is an unsupported combination. Either upgrade the Oracle7 database or use a lower version client. Patches The fix under <Bug:2308496> will cause client connections to report a connect time error (ORA-24439) on an attempt to connect to Oracle7 from an Oracle 9.2 client. This fix will be included in the 9.2.0.2 Patch Set. There will be no patches produced to allow Oracle 9.2 to connect to Oracle7 as such connections are not supported.
