Troubleshooting
This section explains some of the problem scenarios that you may encounter while working with the ODG toolkit in an HP Serviceguard Cluster.
Problem Scenario | Possible Cause | Recommended Action |
If the package log for the standby database contains an error message:
RFS process not found. Please check the network connection.
This message is logged when the standby database is unable to connect to the primary database. This could either be because the primary database is down, or the connection between the primary database and the standby database is lost.
Check if the primary database is up and running and the Data Guard state is healthy. Also check if the connection between the primary database and the standby database is good. If ALERT_MAIL_ID package attribute is set, then a mail is sent to the mail ID when this problem scenario occurs.
If the RAC Data Guard package for RAC database fails to start and logs the following message in the package log file:
Data Guard Broker configuration should not be enabled when MONITOR_DG_BROKER parameter in the Package Configuration File is set to no.
This message is displayed only in Data Guard RAC configurations. This message is logged when the package attribute MONITOR_DG_BROKER is set to no and Data Guard Broker is enabled for the database.
If the Data Guard Broker is enabled for the RAC database, the toolkit package attribute MONITOR_DG_BROKER must be set to yes. Otherwise, the package will not start.
Limitations
The ODG toolkit has the following limitations:
•Both the primary database and the standby database cannot be part of the same Metrocluster. If standby is configured in the same Metrocluster it becomes a redundant configuration because the primary database is already being replicated (hardware replication) between the sites of the Metrocluster.
•It does not support legacy style configuration. Hence, the combinational package of ODG toolkit module and ECMT Oracle toolkit Module (or SGeRAC toolkit database Module) cannot be packaged in legacy style although the ECMT (or SGeRAC) supports legacy style of packaging.
•Multiple standby database instances cannot be supported in the Continentalclusters setup because only one recovery package and only one Data Receiver package can exist within the recovery group. Other standby instances can be configured outside the Continentalclusters environment.
