3 Known problems and limitations

This section lists known problems and limitations.

Home page:

• If you attempt to access the home page and your target database is not loaded into memory, an exception dialog displays. If this occurs, click OK on the exception dialog. Then, check that your TimesTen database is loaded into memory.

• If you navigate to the home page of your TimesTen target immediately after adding your TimesTen target, you may see an error dialog with the exception oracle.sysman.emSDK.emd.comm.NoSuchTargetException. Wait until the target has a "green arrow" to indicate that the target is available and ready to use.

• On the Home page, in the Performance Overview region, the Free disk available (%) line chart is not supported on the Windows x86-64 (64 bit) platform.

Performance page:

• The Write Workload and Read Workload charts can be empty. There is no workaround. (The Write and Read Workload charts are available from the TimesTen IMDB menu. Select Performance, then select Workload.) This problem is fixed in TimesTen 11.2.2.5.0. To enable the charts to be populated in TimesTen 11.2.2.5.0 and higher, execute the ttStatsConfig built-in procedure with the StatsLevel parameter set to ALL.

• On the Performance page under the Statements tab, in the Statements detail region, the pie chart showing the distribution of statements can be slow to paint.

• On the Performance page under the Checkpoints tab, the Checkpoint history table can be slow to paint.

Cache synchronization page:

• On the left hand side of the Cache page, if you Expand All, not all information may be shown. Expand selectively.

Replication monitor page:

• In the Replication Aggregates region, the number of transactions replicated may not equal the number of transaction sent in the Transmitter threads status table. The values in the Transmitter threads status table are more current. Ignore the discrepancy.

• For the Replication Peers table, the order of track numbers in the Peer name column may change on refresh.

Generic:

• Historic statistics for your TimesTen target are not removed when the database is destroyed and recreated. Statistics from the previous database will still display. If you wish to remove the old statistics, drop and recreate the TimesTen target in Enterprise Manager.

• There may be missing replication monitor information if the Enterprise Manager Agent does not run as the same operating system user as the TimesTen instance administrator. Make sure to install the Enterprise Manager Agent as the same operating system user as the TimesTen instance administrator.

• When your TimesTen target database is configured using the connection attribute CacheAWTMethod 0 (SQL array execution), the Method1 (Batches sent to Oracle DB) metric may increment. This is expected.

• If you choose Test Connection after you add a new TimesTen target to Enterprise Manager Cloud Control, you may see an authentication failure error dialog. As a workaround, click OK on the error dialog and do not test the connection. Note: This connection may fail even if your credentials are correct. This problem is fixed in Enterprise Manager Cloud Control 12c Release 3.

• Browsers may crash if there is a large amount of checkpoint history data to display. The default collection interval for checkpoint history is set to 10 minutes. Do not set the collection interval to a value less than five minutes.

• The agent may not pick up the correct time zone on the host. If this happens, do the following:

  1. Log on to the agent host.

  2. Make sure the agent host is configured using the appropriate time zone. For more information on configuring the agent host using the appropriate time zone, contact your system administrator.

  3. Execute emctl stop agent:

     $ emctl stop agent
     

     Results of execution:

     Login as the em repository user and run the script:
     exec mgmt_target.set_agent_tzrgn('testhost.oracle.com:3872','PST8PDT')and commit the changes
     This can be done for example by logging into sqlplus and doing
     SQL> exec mgmt_target.set_agent_tzrgn('testhost.oracle.com:3872','PST8PDT')
     SQL> commit
     

  5. Connect to your database as the Enterprise Manager repository user using SQL*Plus:

     $ sqlplus sysman/sysman
