Code Profiling Utilities

The Code Profiling Utilities, introduced in the H06.07 RVU, consist of two products: the

Code Coverage Utility (codecov, T0746) and the Profile Merge Utility (profmrg, T0747).

To use these tools, applications must be compiled using the H06.07 or later versions of

the TNS/E native compilers. The SPR levels of these compilers are:

These compiler versions provide the required command line options for running the

Code Coverage utilities.

Starting in the H06.09 RVU, the Profile Merge Utility (T0747) and Code Cover Utility

(T0746) are included on the SUT and on the cross-compiler CD. Previously, the Profile

Merge Utility was delivered only on the SUT.

Kernel-Managed Swap File (KMSF)

Integrity NonStop NS-series servers require more swap space than do NonStop

S-series servers. The default is 512 megabytes for each processor. Depending on your

hardware and software configuration, more swap space might be needed. Using

KMSF, monitor the actual virtual memory consumption. To check the size of the

configured swap files for each processor, at a TACL prompt, start NSKCOM and enter

the STATUS SWAPFILE command. For more information on commands and usage,

see the Kernel-Managed Swap Facility (KMSF) Manual.

IOAM and Migrating Existing Data to an

Enterprise Storage System (ESS)

G-series application programs that reside on an ESS and are run on a NonStop

S-series system might require migration changes to run on an Integrity NonStop

NS-series server and H-series RVU. For more information, refer to the H-Series

Application Migration Guide.

The migration of existing data from internal SCSI-attached, 514-byte sector disks to

industry standard, 512-byte sector disk subsystems includes an improved method for

checksum protection. The new checksum protection method employed for unstructured

files requires the data stored on disk be contiguous and aligned in units of 28 kilobytes.

When a nonpartitioned unstructured file is created or migrated to an ESS, the extent

sizes are rounded up to a mod-14 boundary, since an extent page is 2 KB. Rounding

ensures continuity of the data set protected by the checksum. This design ensures the
