exhaustively consumed. When a NIM operation completes on a client machine, the NIM server initiates an operation on the next machine in the group until all group members have been processed, or the time limit has been exceeded. The options are in place for the duration of the NIM operation. Subsequent NIM operations on the group can use different values if desired. The options are valid only for certain operations when a NIM group is used as the target. The NIM operation will fail with an error message if the options are used for individual machine, LPP, or SPOT targets. The options appear near the end of the following NIM SMIT panels that initiate operations likely to generate large amounts of network traffic: • Install the Base Operating System on Stand-alone Clients • Install and Update from LATEST Available Software • Update Installed Software to Latest Level (Update All) • Install and Update Software by Package Name (includes devices and printers) • Install Software Bundle (Easy Install) • Update Software by Fix (APAR) • Install and Update from ALL Available Software • Install mksysb on an Alternate Disk • Clone the rootvg to an Alternate Disk Figure 29 shows an example of the new NIM settings within SMIT. Figure 29. Sample NIM SMIT Panel Showing Group Controls 6.12.2 Resource Lock Contention The lock granularity of the NIM subsystem has been improved to allow more operations in parallel. Previous versions of NIM would lock an object for the duration of some operations, thus preventing any other operation on the same object. 136 AIX Version 4.3 Differences Guide
The locking methodology has been changed to lock the object only for critical parts of the operation. This will allow other operations on the object to complete when in the past they may have waited or timed out. For example, this change will allow a showlog operation to be carried out on a machine resource, which a customer operation is also being carried out. Previously, the machine object would be locked for the entire duration of the customer operation. 6.12.3 Administration Enhancements The NIM sections of SMIT and Web-Based System Manager have been updated to offer function that was previously only available using the NIM command line interface. This includes support for ATM network types and IEEE 802.3 Ethernet networks. 6.13 Paging Space Enhancements (4.3.2) AIX Version 4.3.2 now provides support for up to 32 GBs of memory on RS/6000 64-bit SMP servers. Before AIX 4.3.2, paging space was allocated for the executing process at the time the memory was requested or accessed. This required backing paging space allocated for all pages in the real memory, to save the image of the page. On a large-memory machine where paging was never or rarely required, these paging space blocks were allocated but never be used. In this case, resources were wasted. In AIX 4.3.2, the policy for paging space allocation has been modified to allow a deferred paging space allocation. The allocation of paging space is delayed until it is necessary to page out the page, which results in no wasted paging space allocation. This new paging space allocation method greatly reduces the paging space requirements for systems with large physical memory. 6.13.1 Late and Early Paging Space Allocation There are three kinds of paging space allocation policies used with AIX. The setting of the PSALLOC environment variable determines the paging space allocation mode. Early Allocation If the environment variable PSALLOC is set to early, then the early allocation policy is used. This will cause a disk block to be allocated whenever a memory request is made. If there is insufficient paging space available at the time of the request, the early allocation mechanism fails the memory request. This guarantees that the paging space will be available if it is needed. Late Allocation in Pre-AIX 4.3.2 If the environment variable is not set, then the default late allocation policy is used and a disk block is allocated only when a page in memory is initially accessed, not when it is allocated. Late Allocation in AIX 4.3.2 AIX 4.3.2 modifies the late allocation policy so that a disk block is not allocated until it becomes necessary to page out the page from memory into paging space. In AIX 4.3.2, late allocation will not allocate any disk blocks if there is enough real memory and no paging required for a given application set. System Management and Utilities 137
