First, a tip of the hat to the sysops that keep this running!

Now...



We've got 100 users running an AREV 2.12 app that are constantly getting "String Line Errors".  Environment is NW3.12 patched to D (ptd) level.  Workstations are Win95b (qfecheck ver. 4.00.1111 b)running Intranetware client 2.2.  Client Hardware is all over the place, from four year old home built K-90's & 486's (about 50%), noname P166-233's, a couple of new Acer Power NetPC's, and a couple of new Compaq PII DeskPro EN's.  We also have a dedicated indexer running Win95's command prompt (BOOTGUI=0)



I've got all the settings recommended here (frame type, emm386 /auto, not shadowing ROM, no power saving, True Committ on, don't cache writes, etc., etc).  None of this has helped.



I checked low DOS box memory on various machines using a DOS PROMPT pif set as follows: all auto except EMS, set to 4096.  It ranges from 518k to 595k.  It seems like the machines with the least low DOS memory have the most trouble with string line errors, while the ones up around 585k on up don't have problems.



The AREV app we're running contains well over 500,000 parent records.  The app and data take about 2GB of disk space.  It has been in use since 1992.



1. Am I correct in assuming that this lack of low memory could be the source of problems?  If so, would memory mgt software such as QEMM or another package improve the situation?  Or is there a better solution?



2. I was told that AREV has a "string space" (sorry about the misnomer) maximum of 64k.  Is it possible for AREV to try display more data that it's limit?  There are times when a user has multiple screens displayed, each with much data.  



3. I don't know much about AREV, but with some other non-linear-hash databases, you have to rebuild them.  This has never happened to my knowledge.  The primary indexes only get rebuilt when we see obvious errors on the indexer, i.e. rarely.  Should they get rebuilt more often?  Is there a maintenance routine we should be doing on a scheduled basis?



Thanks in advance...

<QUOTE>OK Art several quesions, but to summarise



1) The error message you report is a little unclear but it'll either be a string space format error or something like that. VERY likely to be caused by low string space. Ensure everything that can be is loaded high, see the difference in string space by loading with (/X /M4096) and without (/O) expanded memory support. Type WHO at TCL to see the string space available. Aim for ] 250K.



2)AREV uses a finite amount of string space - reported as above. More you load the less string space you have.



3)Linear hash is self optimising so requires little maintenance. You should consider running LH_VERIFY, VERIFYLH or whatever on a monthly basis until you're happy, then run quarterly.

<QUOTE>Art,



-The limit to any variable is 64 kB

-the string space is typically 250 kB without expanded memory active -string space is 300 kB+ with Expanded memory active

-you should have 585 kB of memory free below 640 kB to run AREV

-always run AREV with the /XM4096 switch.



Under Win 95, it is the shortcut memory which is supplied to the application. You should get around 600 kB if you use HIMEM.SYS and EMM386.EXE in config.sys, then DOS=HIGH,UMB.



If you use the DOS based Novell VLM.EXE then explore the use of the /X parameter to load this high.



IPXODI /AD can be used if there is no RPRINTER.EXE on the workstation.



If you post your config.sys and autoexec.bat and mem /c readouts from the troubled workstations here (or via email) I will look at whether you can squeeze more memory out of your configuration.

I rebuilt a newer machine yesterday.  When I had MS Client for NW on it, DOS Box low memory was 605k.  Then loaded INC Client32 2.2 & low memory dropped to 519k.  MSDOS loaded low reading from mem went from about 32k to 79k.  In other words, I'm already using all UMB's.  LoadTop in MSDOS.SYS would still be feasible, right?  



Also, INC32 Adv Settings changed are: Cache Writes off, True Commit on, Delay Writes off, NW Protocol BIND NDS. We're using Enhanced mode (32 bit and 16 bit) NDIS driver in the card settings, so I don't think we're using either (but whaddo I know).



Thanks again for the input,

<QUOTE>Just for info purposes. I have not had problems with thefollowing  configuration except when doing some Btree index lookups that use the format WITH DATE GE "1/1/97" AND WITH DATE LE "1/1/98".  When I change

the format to WITH DATE BETWEEN "1/1/97" AND "1/1/98" solves the problem.  I can only assume the two different statements perform the select differently.

<QUOTE>Thanks again, guys.



Got the FAQ and PIF a while ago.  While the PIF recommends loading LHIPXTSR from the "batch file" line in the PIF, I've also seen it recommended (on my BOOST app's web site)that all can be loaded from a batch file.  I like loading LHIPXTSR from the PIF, more appros for Win95, but I'm overruled.



Anyway the batch file is:

c:

cd\arev   (verbatim, no space???)

lhipxtsr.exe /p

g:

cd\boost   (just tried "cd\system" from my WinDir, bombed, could this         be a problem with no path statement in autoexec?  I know I'm          grabbing at straws)

arev BOOST.COLLECTOR /M4096(S)

C:

cd\arev

lhipxtsr/u

<QUOTE>Either will work. I like doing it from a batch file, because then that same batch file can be used for all platforms. The /P option is not needed for a DOS system, but it doesn't hurt, either.

<QUOTE>No more string line errors!!  Just want to say thanks (big time!) to Steve Smith and Spetazurra (which I probably spelled wrong).  We've been using AREV for at least 5 yrs. The guy who set up our network is a CNE.  The staff AREV programmer has been writing AREV for at least seven years that I know of.  



And there by the grace of God go I.  I am neither a CNE or much of an AREV programmer.  I've been working with this situation for 11 months. When I finally disregarded my boss's (the AREV programmer) warnings about changing the startup switches, and added the X to the startup switches, we went from Expanded Memory being unavailable to ~559K being available.  Haven't had problem one since.  This board is the greatest!
