FAQ

Q:

I don't have an Oracle client installed on my workstation. Can I still use Insider to monitor my Oracle databases

A:

Yes. Select Thin Driver connection type when entering your database. Oracle thin driver does not require Oracle client software to be installed on the machine

Q:

I am trying to add an Oracle database however my tnsnames.ora file is not found (TNS names list is not populated)

A:

Press Locate tnsnames button next to TNS names combo and navigate to your tnsnames file, then press OK

Q:

Can Insider support 100+ databases?

A:

Yes. Insider requires about 2Mb per database connection so if you have 100 databases you need approximately 200Mb RAM. To lower CPU utilization you may want to turn off alert pop-up notifications ( Tools > Settings > General > Alert ). Lower refresh rate to avoid excessive load on the network. You can also switch off session statistics ( Tools > Settings > Tuning ) or lower the timeout threshold.

Q:

Why am I getting Parse To Execute Ratio greater than 100% alert?

A:

Please see Why Parse count is higher than execute count in V$SYSSTAT Metalink Note 220617.1. This behaviour is observed on Oracle 8i only

Q:

I am getting lots of login messages in UNIX system log

A:

Select Use Shell option when you specify operating system connection parameters

Q:

I am using Use Shell option and keep getting error messages

A:

Use Shell option does not work with variables within UNIX command prompt like e.g. date/time etc. Try removing variables from UNIX command prompt or switch off Use Shell option

Q:

I am getting a "Not enough priviliges to read alert log" alert

A:

When choosing an operating system user account make sure it has correct priviliges to read from Oracle alert log file. If these priviliges are missing Analyze alert log feature will be disabled and you will receive "Not enough priviliges to read alert log" alert

Q:

I am trying to connect to my physical standby however Insider keeps telling me ORA-12520: TNS:listener could not find available handler for requested type of server or similar error?

A:

To connect to a physical standby or any database in mounted or down state what you should do is:

  • connect as sysdba
  • try using SERVICE_NAME rather than SID in your tnsnames.ora file
  • try configuring the database STATICALLY with the listener. It means lines like
    (SID_DESC =
    (GLOBAL_DBNAME = mydb)
    (ORACLE_HOME = /u01/app/oracle/product/9.2.0.5.0)
    (SID_NAME = mysid)
                                
    should be added to your listener.ora
