Tol'ko v Informix na Besta-88.
(Na nastoyashchih mashinah rusifikaciya delaetsya cherez NLS)
Dannye tipa char v INFORMIX imeyut dlinu 8 bit na simvol i
poetomu mogut hranit' kak anglijskie, tak i russkie bukvy.
Vstroennoj sortirovki po russkomu alfavitu INFORMIX ne
realizoval. Dlya russkoj sortirovki pol'zujtes' predvaritel'noj
perekodirovkoj. (Sm. naprimer podprogrammku koder v
demonstracionnoj baze ZAWOD).
Vo vremya vvoda pol'zovatel' dolzhen pereklyuchat'sya s russkogo na
anglijskij klavishej CONTROL-O, a s anglijskogo na russkij kla-
vishej CONTROL-N.
Dolzhna byt' ustanovlena peremennaya okruzheniya
KEYBMAP="marshrutnoe imya fajla s perekodirovochnoj tablicej"
Po umolchaniyu primenyaetsya KEYBMAP=/usr/informix/keybmap/dasher
kotoraya ustanavlivaet klaviaturu "YAVERTY" pod standart termina-
lov BESTY, i nachal'nyj alfavit - russkij.
KEYBMAP=/usr/informix/keybmap/dasherE export KEYBMAP
Takoj komandoj ustanavlivayut klaviaturu "YAVERTY", i nachal'nyj
alfavit - anglijskij
KEYBMAP=/usr/informix/keybmap/dasherD export KEYBMAP
Klaviatura "JCUKEN" pod standart personal'nogo komp®yutera.
KEYBMAP=/usr/informix/keybmap/dasherP export KEYBMAP
Klaviatura "JCUKEN" pod standart russkoj pishushchej mashinki.
V fajle /usr/informix/keybmap/dasher lezhit tablica perevoda
vvedennyh s klaviatury latinskih simvolov v sootvetstvuyushchie im
russkie. Perekodirovochnaya tablica sootvetstvuet "QWERTY"-ang-
lijskoj klaviature. (T.e. 'a' perevoditsya v 'a', 'c' perevodit-
sya v 'c' i t.d.). Sozdaetsya fajl /usr/informix/keybmap/dasher
programmoj, lezhashchej v /usr/informix/keybmap/crmap_dasher.c
CHtoby ustanovit' drugoe raspolozhenie russkih bukv na klaviature
peredelajte etu programmu. Dlya etogo perestav'te v nuzhnom vam
poryadke soderzhimoe massiva russmap.
V programme /usr/informix/keybmap/crmap_dasher.c staticheskaya
peremennaya init opredelyaet, v kakom alfavite nachinaetsya rabota
INFORMIX. Esli init=1, to snachala ustanavlivaetsya russkij alfa-
vit, esli init=0, to snachala ustanavlivaetsya latinskij alfavit.
Peredelannuyu programmu, estestvenno, nuzhno ne zabyt' otkompili-
rovat' i zapustit' na vypolnenie.
Interesnym sposobom bor'by s rusifikaciej INFORMIX, vypolnennoj
pri portirovanii onoj yavlyaetsya polnyj ot nee otkaz i ispol'zo-
vanie russkogo drajvera klaviatury dlya UNIX.
Dlya nastrojki INFORMIX ispol'zuet peremennye okruzheniya. Vy mo-
zhete izmenit' lyuboe iz dopushchenij, prinimaemyh INFORMIX po umol-
chaniyu, ustanovkoj odnoj ili neskol'kih peremennyh okruzheniya,
raspoznavaemyh INFORMIX.
Naprimer sdelat' tak, chtoby peremennye tipa MONEY izobrazhalis'
ne v formate $149.50, a v formate rub 149.50 kop mozhno komandoj
DBMONEY='rub . kop' export DBMONEY
DBPATH ukazyvaet spisok direktorij gde (pomimo tekushchej)
INFORMIX ishchet bazy dannyh i svyazannye s nimi fajly.
DBPATH=/udd/iwanow:/udd/petrow export DBPATH
Zastavit iskat' bazy dannyh ne tol'ko v tekushchej direktorii, no
i v direktoriyah Petrova i Ivanova
DBPATH=//hostname *OnL*
Zastavit iskat' bazy dannyh OnLine na udalennom komp®yutere.

O NASTROJKE INFORMIX NA TERMINAL.
Dlya nastrojki na terminaly UNIX ispol'zuet fajl termcap ili ba-
zu dannyh terminfo, v kotoryh sobrany opisaniya vseh (ili pochti
vseh) terminalov, sushchestvuyushchih v prirode. Vyyasniv, kakoj tip
terminala podklyuchen k mashine (a zadaetsya eto v peremennoj okru-
zheniya TERM (naprimer TERM=d460 ili TERM=d211)), UNIX nahodit
opisanie etogo terminala baze opisaniya terninalov i nastroiv-
shis' po hranyashchejsya tam informacii, mozhet adekvatno vosproizvo-
dit' na nem informaciyu, podlezhashchuyu vyvodu.
INFORMIX imeet svoj sobstvennyj termcap fajl s opisaniyami ter-
minalov, v nem podderzhivaetsya bol'she vozmozhnostej po sravneniyu
so standartnym termcap UNIX'a. CHtoby INFORMIX pol'zovalsya im
nuzhno prisvoit' ego marshrutnoe imya v peremennuyu okruzheniya
TERMCAP=/usr/informix/etc/termcap
Terminaly TATUNG i DASHER-460 mozhno nastraivat' v dva raznyh
rezhima: STANDARTNYJ, i ANSI.
STANDARTNYJ REZHIM zadaetsya standartnym znacheniem peremennoj
TERM. Dlya TATUNG TERM=d211, dlya DASHER-460 TERM=d460. V etom
rezhime ya i rekomenduyu vam rabotat'. Vklyuchaetsya on po umolchaniyu.
STANDARTNYJ REZHIM imeet sleduyushchie nedostatki:
1. Nekotorye CONTROL-klyuchi v nem ne rabotayut, poskol'ku ih
ASCII kody sovpadayut s kodami "strelok" vpravo/vlevo/vverh/vniz
|to bylo by legko perezhit', esli by etimi klyuchami ne byli
CONTROL-W - klyuch, vyzyvayushchij HELP-podskazku v srede INFORMIX i
CONTROL-X - klyuch "unichtozhit' simvol".
Sleduet zametit', chto terminaly, rabotayushchie v ANSI rezhime (po-
sylayushchie funkcional'nymi klavishami dlinnye ESC-posledovatel'-
nosti) ploho perenosyat rusifikaciyu klaviatury:
2. Nedostatok rezhima ANSI odin: funkcional'nye klavishi i strel-
ki na nem periodicheski sboyat.
Vyglyadit eto tak: desyat' raz vy nazhimaete na "strelku vlevo" i
ona srabatyvaet kak "strelka vlevo" a v odinadcatyj (ili v
vos'moj) raz ona srabatyvaet kak celaya pachka nazhatyh klavish:
ESC, '[', '1', 'D'. Inogda eto mozhet okazat'sya ves'ma nepriyat-
no, osobenno esli za terminalom sidit neopytnyj pol'zovatel'.
Predstav'te: vy nahodites' v ekrannoj forme, nazhimaete strelku
chtoby sdvinut'sya, a vmesto dvizheniya u vas srabatyvaet ESCAPE
("zavershit' vvod") a potom klavisha 'D', na kotoroj v menyu chasto
byvaet naveshano chto-nibud' tipa Drop ili Delete.
Ustanavlivaetsya ANSI REZHIM tak: ustanovite znachenie peremennoj
TERM=d211-tansi ili TERM=d460-tansi sootvetstvenno. Sdelat' eto
mozhno i v obshchem profajle /config/profiles/informix.sh, i v lich-
nom profajle .profile, ili neposredstvenno vruchnuyu s pomoshch'yu
komandy
TERM=d460-tansi export TERM
ili tol'ko na vremya raboty INFORMIX, startovav ego tak:
TERM=$TERM-tansi r4gl
Reshat', kakoj rezhim - STANDARTNYJ s nerabotayushchimi ^W i ^X, ili
ANSI so sboyashchimi klavishami - emu menee protiven, imeet smysl
kazhdomu pol'zovatelyu individual'no, ishodya iz lichnyh vkusov.
Spisok dopustimyh sleduyushchie znacheniya peremennoj TERM dlya TATUNG ET10 :
TERM=d211 Standartnoe znachenie ("Prostoj")
TERM=d211-tansi Vremennyj ANSI rezhim (ANSI)
TERM=d211-132 "SHirokoekrannyj" rezhim (132 simvola v stroke)
TERM=vt220 |mulyaciya vt220 (vt200 v 7-mi bitnom rezhime)
Dopustimy sleduyushchie znacheniya TERM dlya dlya DASHER D460 :
TERM=d460 Standartnoe znachenie
TERM=d460-tansi Vremennyj ANSI rezhim dlya DASHER D460
TERM=d460-127 Ne realizovan
Obespechivaetsya takzhe rabota s drugimi tipami terminalov. Sm.
nachalo fajla /usr/informix/etc/termcap
Besta: NASTROJKA yadra UNIX dlya raboty s INFORMIX
Esli pri zapuske neskol'kih processov INFORMIX program-
my nachinayut sletat' s soobshcheniem 1250 "Unable create a pipe",
znachit v vashej sisteme slishkom malo socketov. A trebuetsya ih po
4 shtuki na kazhduyu zapuskaemuyu programmu INFORMIXa.
Korrektiruyushchie dejstviya: sozdajte nedostayushchie sockety v
kataloge /dev/so , zadajte im normal'nye prava dostupa, i pere-
generite sistemu, ukazav v dfile ih novoe kolichestvo.
VNIMANIE! Ne unichtozhajte staryj unix, poka ne ubedites', chto
novyj gruzitsya normal'no!!!
Peremennye okruzheniya. OnLine 7.*
Klient v moment ustanovki connection posylaet serveru peremennye okruzheniya:
