JR58003: ORACLE CONNECTOR UNABLE TO PLACE WHERE CLAUSE FOR ROWID RANGE READ PARTITIONING

APAR status

• Closed as program error.

Error description

• This causes the Oracle connector stage to abort in multi-thread
  mode but works fine in single thread mode.
  

Local fix

Problem summary

• Oracle Connector is unable to place the WHERE clause for ROWID
  RANGE Partitioning.
  .
  A job performing rowId range partitioning on a source Oracle
  Connector fails with one of the following fatal messages
  (depending on version of Oracle Connector):
  .
  The OCI function OCIStmtExecute returned status -1. Error code:
  907, Error message: ORA-00907: missing right parenthesis.
  (CC_OraStatement::executeSelect, file CC_OraStatement.cpp, line
  NNNN)
  - or -
  The variable nEndPosition has value NNNN which is not valid in
  the current context. (CC_OraUtils::matchingParenthesis, file
  CC_OraUtils.cpp, line NNNN)
  .
  The issue is that the Oracle Connector fails to correctly place
  the WHERE clause in the SQL that's modified in order to do rowId
  range partitioning.
  

Problem conclusion

• The fix enables Oracle CC to generate proper SQL. HOWEVER,
  depending on the original, user-defined SQL, the Oracle Database
   may lose track of the table names and their aliases. After
  applying the patch, running the same job "as is" might result in
   this error:
  The OCI function OCIStmtExecute returned status -1. Error code:
  904, Error message: ORA-00904: MY_ALIAS.ROWID: invalid
  identifier. (CC_OraStatement::executeSelect, file
  CC_OraStatement.cpp, line NNNN)
  This happens because when Oracle prepares the statement, it may
  create multiple temporary views for different parts of the query
  plan and lose track of the table aliases that appear earlier in
  the SQL. The design of the Oracle Connector says to use the
  first table name in the user-defined SQL as the "Table name for
  partitioned reads" if that particular property is unspecified
  in the job. Customer can simply specify the table the "Table
  name for partioned reads" property to assist Oracle.
