The __UHEAP_MARK and __UHEAP_MARKEND macros verify that the default user heap is consistent The check is started by using __UHEAP_MARK and a following call to __UHEAP_MARKEND performs the veri cation If any heap cells have been allocated since __UHEAP_MARK and not freed back to the heap, __UHEAP_MARKEND will cause a panic1 These macros can be nested inside each other and used anywhere in your code You must take care to match the pairs, because a __UHEAP_MARKEND without a prior __UHEAP_MARK causes a panic __UHEAP_FAILNEXT simulates a heap failure (ie out of memory) The macro takes a TInt parameter which speci es which memory allocation call will fail (if the parameter is 1, the rst heap allocation fails, if it s 2, the second allocation fails, and so on) The __UHEAP_RESET macro cancels the failure checking Consider the following example, where a method CTest::SomethingL() makes several memory allocations internally To test the leave safety of the method, it is necessary to check that failure of each of these allocations is handled correctly The best way to do this is to call SomethingL() inside a loop as follows: 1 2 3 4 5 Set the __UHEAP_FAILNEXT parameter Use __UHEAP_MARK to ark the heap Call CTest::SomethingL() inside a TRAP macro Call __UHEAP_MARKEND to check that no memory has been leaked Check the error from the TRAP; if it s KErrNoMemory, you should go round the loop again, incrementing the number of allocations which succeed before the failure point If it s KErrNone, all the allocation points inside SomethingL() have been tested and the test is complete.

We think it's inevitable that every SQL DBMS will support bitmap indexes soon, so we're sure that the following tips will be handy Remember that B-trees are considered effective by optimizers if selectivity is greater than 01 If your queries use "key values" with lower selectivity than 01, the best way to speed them up is with bitmap indexes B-trees and bitmap indexes do not combine well When you search via a B-tree, you get a list of ROWIDs in index-key order When you search via a bitmap, you get a list of bits in ROWID order Because the lists differ in structure, ANDs, ORs, and NOTs require extra conversion steps Assembly-language instructions for AND, OR, and NOT all take only two cycles for each 32-bit word in a bit vector However, no fast assembly-language instruction tells you "how many bits are on in the word" or "which bit is on in the word" Therefore a DBMS is fast at Boolean logic but relatively slow at finding particular rows Bitmap indexes are particularly useful for queries that contain [NOT] EXISTS, UNIQUE, or GROUP BY Bitmap indexes are occasionally used for joins, but that's part of an internal process that the application programmer can't influence Bitmap indexes are particularly useless when a column can be any one of thousands of possibilities Have you ever noticed that "income" reports or questionnaires contain no gross averages or individual figures but only boxes (eg, [] 1500-3000 [] 3001-6000 [] more) That kind of pregrouping is a big aid for bitmap index construction A common recommendation is that a column is a candidate for a bitmap if the number of possible distinct values is less than 1% of the total number of rows For example, if the column is color and the value can be any one of the values in a 256-color display or NULL, the number of rows n the table should be at least 25,700 before you put color in a bitmap index Bitmap indexes are best for large (because a bit of storage is efficient), non-normalized (because there will be many repetitions), static (because updating one row means updating multiple bit vectors) tables.
