AppSync: Oracle-databaser som kjører på ASM-disken, oppdages som frakoblet

En bruker ser databasestatusen som "OK" under AppSync GUI -> Copy management -> Copies -> Oracle Application.
Men serviceplanen som beskytter denne databasen, mislykkes i oppdagelsesfasen. En bruker ser feilene nedenfor i hendelseslogger.

<DATE & TIME>,Application discovery,21cc64f3-795a-42d0-aab5-818615d0e645,MILE_000005,<AppSync Server>,Application discovery phase for <Database Name> completed with errors
<DATE & TIME>,Application discovery,21cc64f3-795a-42d0-aab5-818615d0e645,ORCL_000104,<AppSync Server>,During discovery, AppSync detected that the following database(s) were offline: <Database Name>. As a result, they will not be available for protection.

I serverlogger sender AppSync checkdatabase-kommandoen, og deretter mislykkes:

I agentloggene er databasen tilkoblet fordi tilstanden er som ÅPEN.

Databasen som kjører på ASM-disk og appsync, kan ikke finne ASM-startsiden siden den spør oratab-filen for Oracle Home og ASM home. Mens oratab-filen ikke hadde en oppføring for ASM. Den har bare en oppføring for databasen.

Legg til oppføringen i oratab-filen for både DB- og ASM-forekomst.

Format: <ASM SID>:<grid_home>:Y|N

Eksempeloppføring fra laboratorieoppsettet vårt:

DB1:/u01/app/oracle/product/19c/db_home:N # entry for DB
+ASM:/u01/app/grid/product/19c/grid_home:N # entry for ASM instance
