NAME
ORACA : Oracle Communications Area.
FUNCTION
Contains no code. Provides supplementary communications to/from
Oracle (in addition to standard SQLCA).

**************************************************************
oracchf : Check cursor cache consistency flag. If set AND oradbgf
is set, then directs SQLLIB to perform cursor cache
consistency checks before every cursor operation
(OPEN, FETCH, SELECT, INSERT, etc.).
oradbgf : Master DEBUG flag. Used to turn all DEBUG options
on or off.
orahchf : Check Heap consistency flag. If set AND oradbgf is set,
then directs SQLLIB to perform heap consistency checks
everytime memory is dynamically allocated/free'd via
sqlalc/sqlfre/sqlrlc. MUST BE SET BEFORE 1ST CONNECT
and once set cannot be cleared (subsequent requests
to change it are ignored).
orastxtf: Save SQL stmt text flag. If set, then directs SQLLIB
to save the text of the current SQL stmt in orastxt
(in VARCHAR format).
orastxt : Saved len and text of current SQL stmt (in VARCHAR
format).
orasfnm : Saved len and text of filename containing current SQL
stmt (in VARCHAR format).
oraslnr : Saved line nr within orasfnm of current SQL stmt.
Cursor cache statistics. Set after COMMIT or ROLLBACK. Each
CONNECT'd DATABASE has its own set of statistics.
orahoc : Highest Max Open OraCursors requested. Highest value
for MAXOPENCURSORS by any CONNECT to this DATABASE.
oramoc : Max Open OraCursors required. Specifies the max nr
of OraCursors required to run this pgm. Can be higher
than orahoc if working set (MAXOPENCURSORS) was set
too low, thus forcing the PCC to expand the cache.
oracoc : Current nr of OraCursors used.
oranor : Nr of OraCursor cache reassignments. Can show the
degree of "thrashing" in the cache. Optimally, this
nr should be kept as low as possible (time vs space
optimization).
oranpr : Nr of SQL stmt "parses".
oranex : Nr of SQL stmt "executes". Optimally, the relation-
ship of oranex to oranpr should be kept as high as
possible.
If the symbol ORACA_NONE is defined, then there will be no ORACA
*variable*, although there will still be a struct defined. This
macro should not normally be defined in application code.
If the symbol ORACA_INIT is defined, then the ORACA will be
statically initialized. Although this is not necessary in order
to use the ORACA, it is a good pgming practice not to have
unitialized variables. However, some C compilers/OS's don't
allow automatic variables to be init'd in this manner. Therefore,
if you are INCLUDE'ing the ORACA in a place where it would be
an automatic AND your C compiler/OS doesn't allow this style
of initialization, then ORACA_INIT should be left undefined --
all others can define ORACA_INIT if they wish.
