irgendwie ein "exotisches" Vorhaben. Auf der anderen Seite auch wieder gar nicht, wann man an das gute Geld (LizenzgebÃ¼hren) fÃ¼r eine Hot Stand-By-Lizenz denkt.
Ich selbst verfÃ¼ge leider nicht Ã¼ber die Erfahrung, nach der Du in Deinem Post fragst, habe allerdings etwas gefunden:
Setting up an HADR includes the following requirements:
- HADR is a DB2 optional licensing feature. The full use of HADR is allowed with Enterprise Server Edition (ESE), but you might need more DB2 licenses for the standby server(s). Consult with IBM IM Sales representatives for the details.
- The operating system on the primary and standby databases should be the same version, including the patches. For a short time, during upgrades, they can be different.Â Â
- A TCP/IP interface must be available between the HADR primary and the standby.Â Â
- The DB2 version and level must be the same on both the primary and the standby systems.Â Â
- The DB2 software for both the primary and the standby database must have the same bit size (32-bit or 64-bit).
- Buffer pool sizes on the primary and the standby should be the same. Note that if you build the standby database by restoring the database using the backup copy from the primary, the buffer pool sizes are the same, because this information is included in the database backup.
- The primary and standby databases must have the same database name. This means that they must be in different instances.[list]
- Table spaces must be identical on the primary and standby databases including:
- Table space typeÂ Â
- Table space sizeÂ Â
- Container pathÂ Â
- Container sizeÂ Â
- Container file typeÂ
- The amount of space allocated for log files should also be the same on both the primary and standby databases.
