This is BFreeD, Copyright (c) Allegro Consultants, Inc. BFREED is a demo version of BFree from Allegro Consultants, Inc. --- BFree is the only software that can "free up" Extent B-Tree entries needlessly used by TurboIMAGE. The result is that your system can usually have hundreds more sessions logged on at a time. In addition, BFree can report information about the Extent B-Tree table. BFree currently has two different strategies it employs to save Extent B-Tree table entries. These are referred to as BFree.1 and BFree.2, and can be enabled or disabled independently. BFree.1 saves one entry per opened jumbo dataset (or more). BFree.2 saves two entries per opened database. By default, both kinds of savings are enabled/disabled together. A new user will typically use the STATUS command to see how many Extent B-Tree entries are in use, and how many could be saved by enabling BFREE. --- To install BFREED: :newacct allegro, mgr :altacct allegro;cap= & AM,AL,GL,DI,CV,UV,LG,PS,NA,NM,CS,ND,SF,BA,IA,PM,MR,DS,PH :altacct allegro; access = (r,x,l:any; w,a:ac) :altgroup pub.allegro; cap = BA,IA,PM,MR,DS,PH :altgroup pub.allegro; access = (r,x,l:any; w,a,s:ac) and, put a password on the ALLEGRO account. Upload BFREED to BFREED.PUB.ALLEGRO. --- Usage: RUN BFREED.PUB.ALLEGRO The most used BFREED commands are probably: INFO ... what VSM tables are filling up? STATUS ... report how many entries could be saved BFREED commands: The commands are: CONTACT The CONTACT command displays contact information for Allegro Consultants, Inc. EXIT or // Terminates this program immediately. HELP or ? [prefix] Displays this help information. If you provide a prefix, only those sections with keywords that start with that prefix will be displayed. INFO Reports the status of the various VSM tables. STATUS [QUICK] [SETVAR] The STATUS commands reports the number of in-use Extent B-Tree entries. The SETVAR (or "JCW") option causes STATUS to create some CI variables: BFREE_ENABLED ... true/false if any BFree savings is enabled BFREE_ENABLED1 ... true/false if BFree.1 is enabled BFREE_ENABLED2 ... true/false if BFree.2 is enabled BFREE_PERCENT_FULL ... how full is the Extent B-Tree table BFREE_SEEN ... # of Extent B-Tree entries in use BFREE_SAVED ... # of entries saved by BFree BFREE_SAVABLE ... # of entries savable if BFree had been enabled earlier. The QUICK option causes STATUS to just report the status of BFree savings mode. CLEARREDO DO xxx LISTREDO REDO [xxx] --------------------------------------------------------------- The Extent B-Tree table entries are officially called "nodes", and each node has up to 4 entries in it. However, many people in the HP 3000 community refer to the top-level items in the Extent B-Tree as "entries" instead of "nodes". BFree also refers to them as "entries" to avoid confusion. --------------------------------------------------------------- 2021-04-08 Fixed minor typo of "tree" (should have been "Tree") in one message.
