Re: [U2] Universe Server Hibernation
Many thanks for the responses :) - lost of food for thought!

Wol - the hibernation is not set up yet; and yes; I want to suspend the entire server and operating system to disk - no VMs involved. Our UV server is the server least often shut down or rebooted; to the point where I actually delay OS patches for months on end; having a 100% uptime of 6 months on the UV server is nothing new here. In fact last week's incident was the first in 3 years where this server went down without pre-scheduled downtime. John, a generator is high on my priority list. Proposals and funding for one have been repeatedly rejected during the last couple of years by my directors. We have invested heavily in wireless technology in our warehouses in the last year though, and I'm busy preparing new proposals which should be more open to acceptance, as power outages will have a much bigger impact on our business operations than in the past. We don't have a large user base - just 120 users at present, but that incorporates a whopping 50% growth in just the last year; it's been playing havoc with capacity planning and licensing! Thanks Stuart - it looks like I'll have to do some testing then.

Re: [U2] Universe Server Hibernation
We had serious power issues for a few years while the surrounding roads were under construction. The APC Automatic shutdown process built into the parachute software (donno if this is what it's still called) seemed to work well enough. We never had any issues with UniVerse shutting down or restarting afterwards. We utilize a generator for short outages, but usually the heat gets to a point where we have to shut down after a few hours anyway. -Original Message- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Arnold Bosch Sent: Wednesday, July 20, 2011 6:41 AM To: U2 Users List Subject: Re: [U2] Universe Server Hibernation Many thanks for the responses :) - lost of food for thought!

[U2] SELECT question, paginated select.
I'm working on a screen in our webapp where we're using a dojo widjet to create a drop down with client names. The problem is that we have 1,000's of clients and when we do a SELECT on this many clients it takes a while. I know we can index the field but I was wondering if you can do smart selecting in UniVerse. For example if I wanted to use this query: SELECT CLIENT WITH @ID = A] SAMPLE 10 (returns 10 clients starting with the letter A). I want to paginate my drop down so the first query has the above data. The problem I'm facing is that I don't know how to get the NEXT 10 clients? Is there a way to do this? For example if I wanted to return the next 10 CLIENTS, without including any of the first 10.

Hi Chris: This is a problem we first tried to figure out when we went to the Web. The easiest way for us was to save off the client select using SAVE.LIST.

Doug, Thanks for the reply. I'm a little confused as to how to execute your suggestion though. EXECUTE 'SELECT CLIENT WITH @ID = A] SAMPLE 10' CAPTURING CAPTURED PASSLIST REC.COUNT = @SELECTED*SYSTEM(11) IF REC.COUNT THEN EXECUTE 'SAVE.LIST CLIENT.LIST ' END RETURN In the above example we SELECT 10 clients, then the 10 clients are saved to CLIENT.LIST. How would we go about getting the next 10 clients?

Re: [U2] SELECT question, paginated select.
Chris:
For instance, we have checks file. A number of our clients have over a
million records in the file. It's indexed on vendor no. and check
date. The index would look like:
00CAPGE15857 (7 digit vendor and 5 digit date)
This is a left justified so it's easy to sort and select. I can select
any item in the file for any vendor and even limit it to any date...
SELECT VENDCHECKS WITH INDEX_1 = 00CAPGE]
SELECT VENDCHECKS WITH INDEX_1 00CAPGE15786
Within a second or less you'll get your data since an index is being
selected. If you want to traverse the index, you'll need to do it
within BASIC. In D3 they had the KEY() function, In UniData they have
the SETINDEX, READFWD, and READBCK, commands (with a few other
derivatives). But these allow you to set an index to start with (let's
say in wanted to start accessing checks with vend# CAPGE and with
checkdate of 21 Mar 2011). From here you can read forward or backward
for {n} number of records. When you have the number you want you need
to return to the calling program with this data including the top and
bottom values. You'll display what you want then if you go to the next
page you can READFWD from the bottom of the page. To go backward you'll
READBCK from the top of the page.
For UniVerse, you'll have to do a bit of a dance, although, compared to
D3 you have to do a bit of a dance in UniData. But I know UniData works
well and assume it's also true with UniVerse, although UV doesn't store
in a B-Tree, so the first item read may have a large number of items in
the list.

Re: [U2] SELECT question, paginated select.
Chris, I agree with Bill, using an index is your best solution. Are you able to apply any kind of filter criteria to the names? If not here's one of your dilemmas... If you make your drop down list too small nobody will use it because it will take too long to get to anyone beyond the A's. If you make it too long it will be cumbersome to find someone on the page and the build time of the drop down list on the client side may be too slow. I strongly recommend, from experience, using something other than a dropdown list, even using a combo box list allows the user to provide some criteria to narrow the search.

Re: [U2] SELECT question, paginated select.
Bill,
I guess my question is regarding how to traverse the index. In this case the
field we're using is the @ID, so it's
indexed by default. Below you stated that we have to traverse in BASIC, is this
using the SAVE.LIST approach that Doug
talks about?
In your example:
SELECT VENDCHECKS WITH INDEX_1 = 00CAPGE]
how would you limit that to the first 10 entries? And then how would you get
the next 10 after that?
We're on UniVerse so I assume the UniData commands below won't work for our
application.

Re: [U2] SELECT question, paginated select.
Curt, My problem is understanding how to traverse the query. Our dropdown is paginated, we can specify the # of results per paginated drop-down so it being super long or short isn't an issue. The problem is getting the SELECT statements/UniVerse to match what we want the dropdown to do. For example if I query a table called CLIENT which has @ID indexed, I do the following: EXECUTE 'SELECT CLIENT BY @ID' My questions are: #1) How would I specify 10 results back from the query? #2) How would I 'pick up' where I left off for page 2 (values 11-20)? Doug mentioned using SAVE.LIST to do this, Bill says that you have to do a dance in UniVerse. I guess I'm curious what this dance is that I need to do? If it's not handled in the SELECT then what technique are you using in UniVerse?

Re: [U2] SELECT question, paginated select.
We have had similar problems - one solution that works very well is to not contact the database to do big selects like this. We write such data into xml files onto the web server and make them accessible via a web service that is cached. This speeds up performance considerably, it sounds like a supplier list is not something that changes every minute so caching should not be a problem. You can then do whatever paging etc required within the xml and webservice. -Original Message- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Chris Austin Sent: 20 July 2011 18:15 To: u2-users@listserver.u2ug.org Subject: [U2] SELECT question, paginated select.

Re: [U2] SELECT question, paginated select.
If your objective is: To get the search results down to something small that the user can deal with... I believe the person that mentioned a combo box, would be your Easiest Solution. However, it may not be the fastest, because you will inevitably have to use a wildcard search in RETRIEVE to get some data back. You said you were using dojo... so here is a link to comboboxes in dojo. http://dojotoolkit.org/reference-guide/dijit/form/ComboBox.html Basically the user could type in a search phrase, and as the user types you would fire up a Universe Query (however you are doing that), that would grab some data and send it back. Then the user would have a scrollable list of results they could choose from. I have never used dojo. I have used jquery ui and made it work. http://jqueryui.com/demos/autocomplete/ However, you should set a minimum number of characters before it fires the search (something like 3 or 4), otherwise, every time the user types a character, another UV SELECT will fire. Remember, how I said this is the easiest and NOT the fastest. So if your website is going to have a hundred hits every few minutes on this search box, maybe this is not a good idea for you. In addition to that, the subroutine on the Universe side would probably have to do a wildcard search. Something like: SELECT CLIENT WITH @ID = AUTO] If the ID is indexed, what I have noticed is... that a left OR right wildcard search goes pretty quickly. However, if you do a wildcard search on both sides, I don't believe it uses the index at all. (i.e. SELECT CLIENT WITH @ID = [AUTO]) I don't know if wildcards use indexes at all, I'm sure someone knows that answer on here. I'm fairly sure that you cannot query on multiple indexes with one RETRIEVE statement. If you find that your system is not fast enough to do those wildcard searches every time one fires, then, I do not have an answer for that. It seems to me that you would have to do some fancy BASIC programming on the Universe side for that... I even dabbled in using FINDSTR (In UniBASIC) for that, but, it did not seem to be any faster than a wildcard search on our system. It actually seemed slower once the string of names became too long.

Re: [U2] SELECT question, paginated select.
Chris:
Indexes aren't created by default. The @ID is hashed into the file
which allows you to retrieve an item via the @ID with a single disk read.
To index, you need to create a dictionary. I create all our index
dictionaries as INDEX_{n} (e.g. INDEX_1, INDEX_2, etc). They're
I-Descriptors like:
5 Allegis (0)- AE DICT ARTLEDGER INDEX_1
Top of INDEX_1 in DICT ARTLEDGER, 9 lines, 434 characters.
*--: P
001: I This is the INDEX dictionary that determines what the index is
for. Structure:
Client# Cust# YrMo Ctrl#
002: OCONV( CLIENTNO, 'MR%4' ) : OCONV( UNITNO, 'MR%7' ) : YRMO_PSTD :
OCONV( INVNO, 'MR%7' )
003:
004:
005: 24L
006: S
007:
As you can see they simply build a string that will be indexed by the
CREATE.INDEX command at TCL. It looks like:
5 Dev (0)- LIST.INDEX ARTMASTER
Alternate Key Index Details for File ARTMASTER Page 1
File.. ARTMASTER
Alternate key length.. 45
Node/Block size... 4K
OV blocks. 1 (1 in use, 0 overflowed)
Indices... 3 (0 D-type)
Index updates. Enabled, No updates pending
Index-Name.. F-type K-type Built Empties Dups In-DICT S/M
F-no/VF-expr
INDEX_1 V TxtYes Yes Yes Yes M SUBR(
'-CATS', S
UBR(
T.LFM, NI
D,
@FILE.NAME, @
RECORD
), REUSE(
OCONV(
*OCONV(
@ID,
'G1*1' )*,
'MR%7' ) ) )
.
.
Then you have to execute the BUILD.INDEX command from TCL to populate
the index. Here's some quick and dirty BASIC code that manages an
index. First you need to open the file that's indexed.
*
*** Open files
FileErr = NULL$
OPEN '', 'ARTLEDGER' TO ARTLEDGER ELSE FileErr := ' ARTLEDGER'
IF FileErr NE NULL$ THEN
HLDMSG = Missing files: : FileErr
GOTO ABORT.PROGRAM
END
Then you need to define the index variable...
** Read index codes from ARTLEDGER file
ARL.INDEX.1 = INDEX_1
A.CODE = ARL.INDEX.1
Then you need to use the index.
** Read transaction pointers
DONE = 0
TextLine = NULL$
TOP.START = CLIENT R(%4) : CUST R(%7)
NAME.KEY = TOP.START
IF NOT(ReverseSort) THEN
SETINDEX A.CODE, NAME.KEY ON ARTLEDGER; ** UD version
END ELSE
TEST.KEY = TOP.START : ICONV('7B', 'MX0C'); ** UD version
SETINDEX A.CODE, GE TEST.KEY ON ARTLEDGER ; ** UD version
READXFWD NAME.KEY FROM ARTLEDGER ELSE ; ** UD version
SETINDEX A.CODE, LAST_ALT_KEY ON ARTLEDGER ; ** UD version
END ; ** UD version
END
*
** Loop through transactions
LOOP
IF ReverseSort THEN ; ** UD version
READXBCK NAME.KEY FROM ARTLEDGER ELSE DONE = 1 ; ** UD version
END ELSE ; ** UD version
READXFWD NAME.KEY FROM ARTLEDGER ELSE DONE = 1 ; ** UD version
END ; ** UD version
KEY.ID = @ID ; ** UD version
IF NOT(DONE) THEN ; ** UD version
treeClient = FIELD(KEY.ID, '*', 1)
treeCust = FIELD(KEY.ID, '*', 2)
RefNo = FIELD(KEY.ID, '*', 3)
*
** Validate client and customer
IF treeClient NE CLIENT THEN EXIT
IF treeCust NE CUST THEN EXIT
*
** Read transactions
READ HREC FROM ARTLEDGER, KEY.ID ELSE HREC = NULL$
SOURCE = HRECARTLEDGER.SOURCE
DESC = HRECARTLEDGER.DESC
TDATE = HRECARTLEDGER.TDATE
AMOUNT = HRECARTLEDGER.AMOUNT + 0
ACCT = HRECARTLEDGER.ACCTS
HNAME = HRECARTLEDGER.LNAME
PREV = HRECARTLEDGER.PREV
CURR = HRECARTLEDGER.CURR
CUSTNO = TRIM(HRECARTLEDGER.ASSOC_CUST)
*
** Build output line

Re: [U2] SELECT question, paginated select.
Chris, Bscan is a universe command that will let you traverse a secondary index. Say the last company on the page was ABC Company, your BSCAN commands match value could be Abc and then step thru the list with a loop. The UV docs description isn't too bad. Curt Chris Austin cjausti...@hotmail.com wrote: I have no idea what the BSCAN directive is? Is that a UniVerse command?

Curt, My problem is understanding how to traverse the query. Our dropdown is paginated, we can specify the # of results per paginated drop-down so it being super long or short isn't an issue. The problem is getting the SELECT statements/UniVerse to match what we want the dropdown to do. For example if I query a table called CLIENT which has @ID indexed, I do the following: EXECUTE 'SELECT CLIENT BY @ID' My questions are: #1) How would I specify 10 results back from the query? #2) How would I 'pick up' where I left off for page 2 (values 11-20)? Doug mentioned using SAVE.LIST to do this, Bill says that you have to do a dance in UniVerse. I guess I'm curious what this dance is that I need to do? If it's not handled in the SELECT then what technique are you using in UniVerse?

Chris, I agree with Bill, using an index is your best solution. Are you able to apply any kind of filter criteria to the names? If not here's one of your dilemmas... If you make your drop down list too small nobody will use it because it will take too long to get to anyone beyond the A's. If you make it too long it will be cumbersome to find someone on the page and the build time of the drop down list on the client side may be too slow. I strongly recommend, from experience, using something other than a dropdown list, even using a combo box list allows the user to provide some criteria to narrow the search.

So, SAMPLE isn't really a solution but indexing is. We do this all the time, but we have to use indexing. In fact, we parse through a file with millions of records to get a page full of stuff and the pop-up list is instantaneous.

Re: [U2] SELECT question, paginated select.
You only need to use the second select if you are sorting (using the BY). I believe if you are just doing a select, then you can append the WITH PAGE = x to your statement. I don't know how your doing your SELECT from the web page. I don't know if you can stack selects from it, so it will execute one SELECT, then follow it up with a second SELECT based on the results of the first SELECT.

Re: [U2] SELECT question, paginated select.
You understand that the value for PAGE is specific to the SELECT / LIST which is why when you list the names, it displays as page 1, which is based on that output. When you did the select, it pulled from the page numbers from that selection. As to how it works. If I understand correctly myself @1 is the results of the first value in an I - descriptor, which apparantly is not cleared from item to item in a listing, but is zero'd at the beginning of a select/list. So...the first row, @1 = 0, and we do an @1+1, which adds 1 to the 0 and now 1 becomes @1 (the first value), and the next row uses the previously uncleared value, and so on. Now, I don't know if this is a bug (not clearing the value) or if it's supposed to do that! So if it's a bugit could stop working on a later release of UV, if it's a feature, it's a cool one.

You understand that the value for PAGE is specific to the SELECT / LIST which is why when you list the names, it displays as page 1, which is based on that output. When you did the select, it pulled from the page numbers from that selection. As to how it works. If I understand correctly myself @1 is the results of the first value in an I - descriptor, which apparantly is not cleared from item to item in a listing, but is zero'd at the beginning of a select/list. So...the first row, @1 = 0, and we do an @1+1, which adds 1 to the 0 and now 1 becomes @1 (the first value), and the next row uses the previously uncleared value, and so on. Now, I don't know if this is a bug (not clearing the value) or if it's supposed to do that! So if it's a bugit could stop working on a later release of UV, if it's a feature, it's a cool one.

Re: [U2] SELECT question, paginated select.
I just answered my own question right after I sent that last reply..lol. The
PASSLIST way (which I will not be using btw) is below:
SEL.STMT = 'SELECT CLIENT BY NAME WITH NAME = A]'
EXECUTE SEL.STMT CAPTURING CAPTURED PASSLIST
IF (SYSTEM(11)*@SELECTED) THEN
LIST.STMT = 'SELECT CLIENT WITH PAGE = 4'
EXECUTE LIST.STMT CAPTURING CAPTURED PASSLIST
LOOP WHILE READNEXT CLIENT.KEY
CALL LFSIO.DATAFILE('QREAD*CLIENT',CLIENT.REC,CLIENT.KEY,'','')
PRINT CLIENT.KEY:' ':CLIENT.RECCL$NAME
REPEAT
END
RETURN
Like you said, why do 2 executes when you don't need to, although when you
stack your SELECT commands like you did with the following:
CMD1 = 'SELECT CLIENT BY NAME WITH NAME = A]'
CMD1-1 = 'SELECT CLIENT WITH PAGE = 1'
EXECUTE CMD1 RTNLIST CLIENT.LIST
You would think that does 2 executes, 1 behind the scenes but maybe not? It
must someone execute the first SELECT doesn't it, or is it a system level
command when you stack select's that the system processes 1 first, then the 2nd
with the first's results.

Re: [U2] Universe Server Hibernation
Perhaps once you have the initial user input, then fire the backend off as a phantom - if you need to check progress, write progress inf out to a file that you could LIST from another session Ross Ferris Stamina Software Visage Better by Design! Ross, thanks; the processes run in serial from a paragraph list - unfortunately it needs some user data inputs to start up thus the need for a telnet session on the server console to start it; we learnt years ago it's not good to run this lot from a networked session! No SAN / NAS - just a proper RAID system in the server itself. The console telnet session is my main concern though... I might have to see if we can start the processing off from a local UV shell; that might be more feasible than a local telnet session.
