5.9 Support for Image Sections in Galaxy Shared Memory

OpenVMS Galaxy offers the ability to share data between Galaxy instances, (provided by OpenVMS as Galaxy global sections). OpenVMS Version 7.3--1 adds support in the INSTALL utility and the image activator to place write shared image sections in Galaxy global sections. This feature allows existing applications that share data using writeable image sections to be extended to a Galaxy environment.

INSTALL/ADD WRITABLE=GALAXY places write shared image sections in Galaxy global sections. You can also use the IDENT keyword with GALAXY to include the image identity in the name of the Galaxy global section. Doing this lets you use multiple versions of an image simultaneously in a Galaxy system.

Refer to the OpenVMS Alpha Partitioning and Galaxy Guide for more details.

5.10 Larger Mailbox Buffer Quotas

Prior to Version 7.3--1, the maximum size for the mailbox buffer quota was 64,000 bytes. OpenVMS Alpha Version 7.3--1 supports the creation of mailboxes with larger buffer quotas for improved application scaling.

When creating a mailbox with the $CREMBX system service, you can explicitly supply a mailbox buffer quota with the BUFQUO parameter. If not, the mailbox buffer quota is implicitly supplied by the system parameter DEFMBXBUFQUO.

Note the following:

Temporary mailboxes do not have a specific size limit.
The size of the mailbox is subtracted from the BYTLM quota of the process.
Permanent mailboxes do not consume process quota; however, any data in a mailbox consumes nonpaged pool.

5.11 RMS New Features

The following sections describe new RMS features added to the OpenVMS Alpha Version 7.3--1 operating system that improve I/O performance and enable easier porting from UNIX to OpenVMS Alpha.

5.11.1 Increase in Default I/O Transfer Size to Reduce I/O

The multiblock count for a sequential disk file sizes the RMS intermediate buffer for disk block transfers; this count serves as the I/O transfer size. The system default multiblock count is increased from 16 to 32. This increase reduces sequential file read or write I/O requests by a factor of 2. If the application does not assign the multiblock count explicitly (using the RAB$B_MBC setting) or as a process default (using the DCL command SET RMS_DEFAULT), the new system default multiblock count of 32 applies.

The process or system multiblock count default parameters (set with the SET RMS_DEFAULT/BLOCK_COUNT or SET RMS_DEFAULT/SYSTEM/BLOCK_COUNT command, or with or the SYSGEN parameter RMS_DFMBC) can dynamically restore the default value for a process or system to the former value of 16 blocks. You can also increase the multiblock count to greater than 32 at either the process or system level, after making appropriate changes to working set quotas. The maximum multiblock count is 127 blocks. Because a larger RMS buffer can lead to increased page faulting by a process with a small working set quota, the increase in the system default is limited to 32.

Because files opened as process-permanent files (PPF) by DCL are not affected by process or system multiblock defaults, DCL file opens are not affected by this improvement. However, note that the change to the system multiblock count default can affect any privileged application that uses the FAB$V_PPF (undocumented) option to open a process-permanent file, if the application does not assign the multiblock count explicitly in the application itself (using the RAB$B_MBC setting).

While this multiblock increase is compatible in a mixed cluster, it has an indirect effect on VAX or older Alpha versions. If a shared sequential file is first opened from the new release, the system multiblock default is 32 blocks. Because the first accessor determines the multiblock count for all subsequent accessors, 32 is the multiblock count for any subsequent accessors opening the file from an older system.

This new feature also indirectly changes the default extend quantity, which uses 64 blocks (two times the multiblock count of 32) instead of the current 32 blocks (two times the default multiblock count of 16).

5.11.2 Support for POSIX-Compliant File Timestamps

To enable easier porting of UNIX applications to OpenVMS Alpha, RMS adds support for POSIX-compliant file timestamps. The XABDAT structure has been extended to include the POSIX-compliant access date, attribute modification date, and data modification date ($OPEN and $DISPLAY). This mechanism can also be used to set all dates on a $CREATE, which is likely to happen in the case of a file restoration. Support for these dates is restricted to ODS-5 volumes and requires the volume to be enabled for access date support.

Updating the POSIX-compliant access date, attribute modification date, and data modification date values through RMS is supported using the XABITM structure.

XABITM$_NORECORD can be used to suppress update of access time.

5.11.3 New System RMS Write-Behind Performance Option

An existing user write-behind (RAB$V_WBH setting in RAB$L_ROP) option is available for unshared sequential files to request that RMS overlap writes to disk. Specifying the write-behind option ensures that at least two buffers are allocated by RMS at connect time. When one buffer has been filled with records, RMS switches to the second buffer and issues an asynchronous QIO to write the contents of the first buffer out to disk. RMS does not stall the process, but rather continues to process records in the second buffer while the QIO for the first buffer is completing. Overlapping I/O can be a big performance win for some applications.

OpenVMS Alpha Version 7.3--1 introduces a new system RMS write-behind performance option as a dynamic SYSGEN parameter (RMS_SEQFILE_WBH) to externally request RMS to implement the write-behind feature as a system default (refer to the OpenVMS System Management Utilities Reference Manual). If this system option is set, RMS implements the existing RMS user write-behind option as a system default (regardless of the RAB$L_ROP RAB$V_WBH setting) whenever write access is requested for an unshared sequential file that is opened for image I/O.

This feature is a system option. It is not the default, however, for the following reasons:

Enabling write-behind involves a change in error reporting that could affect some applications. (A write error might be reported for a subsequent operation rather than for the write on which the error occurred.)
The allocation of an additional RMS intermediate buffer might result in more page faulting if process working set quotas are insufficient.

5.12 SDA New Features

OpenVMS Alpha Version 7.3--1 performs a faster large memory dump that significantly reduces the time to write a system crash dump file.

There are also a number of new commands and qualifiers for the System Dump Analyzer (SDA), including the new SDA Extended File Cache (XFC) commands. For more information, refer to the OpenVMS Alpha System Analysis Tools Manual.

5.12.1 New VALIDATE TQE Command

The new VALIDATE TQE command validates all the data structures associated with timer queue entries (TQEs).

5.12.2 New TQE Type

The SHOW TQE command displays timer queue entries (TQEs), including the following new TQE type:

Column Symbol Description

6 N TQE should not be deallocated at AST completion.

-- TQE should be deallocated at AST completion.

Column	Symbol	Description
6	N	TQE should not be deallocated at AST completion.
	--	TQE should be deallocated at AST completion.
