Temat: problem ze stabilnoscia Oracle 11.2.0.2 RAC na Solaris 10

Witam

Mam zainstalowane Oracle 11.2.0.2 RAC system na OS Solaria 10.
Co pare dni mam problem ze stabilnością systemu - 1 wezel rebootuje 2gi albo na odwrót, tylko że nie mogę namierzyć dlaczego tak się dzieje...
Mam 2 wezly, nazwane Mars i Venus. Przykładowo dzisiaj wezel Mars zrestartowal 2gi wezel Venus (via IPMI), tylko dlaczego... W alercie db jest tylko zapis ze mial timeout'y wiec pewnie nie przeszedl sciezki komunikacji, ale nic konkretnie...

restart nastapil ok 02:30…


Db alert log na Mars:

Administruje RAC dopiero od 2 miesięcy :/ więc doświadczenie żadne... Wczesniej pare lat 8i bez RAC... Czy po tych wcześniejszych logach można coś wywnioskować która ścieżka odpytywania zawiodła ? tzn. o ile dobrze rozumiem to ClusterWare sprawdza dostepnosc nodow wysylajac np komunikat przez siec a odbierajac przez dysk w ten sposob sprawdzajac 1 i 2... i na odwrot... co tutaj zawiodlo ? brak odp przez siec czy z dysku ?

pozdrawiam

nie do konca.. o ile pamietam - gdzies masz plik konfiguracyjny ntpd; zrob moze:

- find /etc | grep -i ntp | grep -i conf
- przecatuj plik ktory znajdzie, zobaczysz w nim parametry uruchamiania ntpd

w wolnej chwili sie upewnie ze glupot nie pisze, ale raczej nie :)

NTP Daemon must be re-configured to support Oracle Grid Infrastructure. The following changes should be made:

- Modify /etc/sysconfig/nptd. Change the following line:
OPTIONS="-u ntp:ntp -p /var/run/ntpd.pid"
TO
OPTIONS="-x -u ntp:ntp -p /var/run/ntpd.pid"

- Modify /etc/sysconfig/ntpclient. Change the following for all OPTIONS lines:
OPTIONS="-u ntp:ntp -p /var/opt/ntpclient/ntpclient.pid -c /etc/opt/ntpclient/ntp.conf"
TO
OPTIONS="-x -u ntp:ntp -p /var/run/ntpd.pid -c /etc/opt/ntpclien
t/ntp.conf"

- Restart NTPD by executing „/etc/init.d/ntpclient restart‟ or „service ntpclient restart‟.

hmmm, u mnie nie ma /etc/sysconfig ale to chyba piszesz o linuxach... w Solarisie jest xntpd i nie ma takich opcji o jakich piszesz, xntpd startuje u mnie bez parametrow i ma configa takiego jak wczesniej wyslalem, sam xntpd ma opcje ktore mozna mu podac ale nie ma -x ani -u

rzuc okiem na oracle'owe dokumenty i poszukaj analogicznych; opcja -x sluzy temu zeby w razie stwierdzenia niezgodnosci czasu na nodzie nie nastepowala doza jednorazowa korekta, ale zeby byl rozlozona w czasie na szereg drobnych; to nie musi byc powodem rebootow i jakich piszesz, ale moze byc jedna z przyczyn - a daje glowe ze solaris ma podobny parametr dla ntpd

rzuc tez okiem na parametry systemu/jadra; oracle sugeruje szereg zmian dla linuksa, dla solarisa pewnie tez; podobny watek znalazlem w sieci, rozwiazaniem bylo:

===

After setting below Oracle Suggested parameters we are not seeing LMON issue .

DRM Parameters :
_gc_undo_affinity= FALSE
_gc_affinity_time=0

gdp Strack parameter :

ksb_disable_diagpid = TRUE

Skąd pochodzą volumeny dla asm? fc, iscsi? Sprawdź czy tu masz wszystko ok.
