1) Function Pointers Declaring Function Pointers Similar to a variable declared as pointer to some data type, a variable can also be declared to be a pointer to a function. Such a variable stores the address of a function that can later be called using that function pointer. In other words, function pointers point to the executable code rather than data like typical pointers. eg., void (*func_ptr)(); In the above declaration, func_ptr is a variable that can point to a...

Target Audience: Oracle SuperCluster customers The primary objective of this blog post is to provide some related information on this obscure tool to inquisitive users/customers as they might have noticed the osc-interdom service and the namesake package and wondered what is it for at some point. SuperCluster InterDomain Communcation Tool, osc-interdom, is an infrastructure framework and a service that runs on Oracle SuperCluster products to provide flexible monitoring and...

The examples shown in this blog post were created and executed on a Solaris system. Some of these tips and examples are applicable to all *nix systems. Digest of a File One of the typical uses of computed digest is to check if a file has been compromised or tampered. The digest utility can be used to calculate the digest of files. On Solaris, -l option lists out all cryptographic hash algorithms available on the system. eg., % digest -l sha1 md5 sha224 sha256 .. sha3_224...

Back in 2014, I posted Moving Oracle Solaris to LP64 bit by bit describing work we were doing then. In 2015, I provided an update covering Oracle Solaris 11.3 progress on LP64 conversion. Now that we've released the Oracle Solaris 11.4 Beta to the public you can see the ratio of ILP32 to LP64 programs in /usr/bin and /usr/sbin in the full Oracle Solaris package repositories has dramatically shifted in 11.4: Release 32-bit 64-bit total Solaris 11.0 1707 (92%) 144 (8%) 1851...

In Solaris 11.3 we provided the ability to use the Silicon Secured Memory feature of the Oracle SPARC processors in the M7 and M8 families. An API for applications to explicitly manage ADI (Application Data Integrity) versioning was provided, see adi(2) man page, as well as new memory allocator library - libadimalloc(3LIB). This required either code changes to the application or arranging to set LD_PRELOAD_64=/usr/lib/64/libadimalloc.so.1 in the environment variables before...

If you look closely at the listings for the Oracle Solaris 11.4 Reference Manuals and the previous Oracle Solaris 11.3 Reference Manuals, you might notice a change in some sections. One of our “modernization” projects for this release actually took us back to our roots, in returning to the man page section numbers used in SunOS releases before the adoption of the System V scheme in Solaris 2.0. When I proposed this change, I dug into the history a bit to explain in the...

Solaris 11.4 comes with a number of enhancements that allow the elfdump utility to display a wealth of information that was previously hidden in Solaris core files. Best of all, this comes without a significant increase in core file size.

Starting with Solaris 11.4, program headers in Solaris ELF objects have explicit names associated with them. These names are used by libproc, elfdump, elfedit, pmap, pmadvise, and mdb to eliminate some of the guesswork that goes into looking at process mappings.
