critical impact:

dbopen and mpool_* routines - not supported (CrUn255)

Problem description

The identified functions exist on Tru64 UNIX, but not on HP-UX.

The mpool routines are the library interface that provides page-oriented buffer management of files. The buffers may be shared between processes:

• mpool_open - Initializes a memory pool.

• mpool_filter - Intends to make transparent input and output processing of the pages possible.

• mpool_new - Takes an MPOOL pointer and an address and allocates a new page.

• mpool_get - Returns a pointer to a page.

• mpool_put - Unpins the page reference.

• mpool_close - Frees up any allocated memory associated with the memory pool cookie.

• mpool_sync - Writes all modified pages associated with the MPOOL pointer to the backing file.

• dbopen - Opens a file for reading or writing. It is the library interface to database files.

Solution description

Although the libdb library is not available on HP-UX, one possible solution is to download the Berkeley DB 1.85 version of this library from Sleepycat Software. This version does contain the mpool_* and dbopen functions used on Tru64 UNIX Version 5.1B.
