Tuning Secure File Copy For Performance
When scp is too slow, and rdist over scp is more functionality than you need, look at sftp.
The sftp command set will be familiar to anyone who has used ftp.
Sftp allows use of a batch file, and it has a tunable buffer size. The -B flag controls the tunable buffer size and is useful when copying files over wide links that have latency. Tests over a DS3 have shown 20% throughput increases simply by increasing the default buffer of 32K. There are limits, and you can experiment on your platforms. Choosing a value too high will result in a message such as, "Outbound message too long 262169".

Release Tuxedo Connections
If the MAXWSCLIENTS had been reached, additional users can not log in to Tuxedo. One way to release connections in Tuxedo is to kill the WSH processes, then use the tmadmin bbclean command.
Count the current tuxedo connections (including the internal users)

Capture and Transfer Oracle Statistics
The dbms_stats Oracle-supplied package makes it easy to back up and restore statistics.
Create the table where statistics will be captured. dbms_stats.create_stat_table
dbms_stats.export_schema_stats
This requires a table name where the statistics will be stored. This table can be exported (like any other table) and imported into a development database.
dbms_stats.import_schema_stats
Example of capturing and transferring statistics:
Create the table where statistics will be captured. dbms_stats.create_stat_table
SQL> exec dbms_stats.create_stat_table('SCHEMAOWNER', 'STATTAB')
PL/SQL procedure successfully completed.
dbms_stats.export_schema_stats
This requires a table name where the statistics will be stored. This table can be exported (like any other table) and imported into a development database.
dbms_stats.import_schema_stats
Example of capturing and transferring statistics:
SQL> exec dbms_stats.export_schema_stats('SCHEMAOWNER','STATTAB')
PL/SQL procedure successfully completed.
$ exp file=stattab.dmp tables=SCHEMAOWNER.stattab compress=n
About to export specified tables via Conventional Path...
Current user changed to SCHEMAOWNER
. . exporting table STATTAB
8701 rows exported
Export terminated successfully without warnings.
>>> Copy export file and change ORACLE_SID as appropriate.
$ sqlplus SCHEMAOWNER@qa
SQL> delete from stattab;
$ imp file=stattab.dmp fromuser=SCHEMAOWNER touser=SCHEMAOWNER ignore=y
Export file created by EXPORT:V09.02.00 via conventional path

. importing SCHEMAOWNER's objects into SCHEMAOWNER
. . importing table "STATTAB"
8701 rows imported
Import terminated successfully without warnings.
$ sqlplus SCHEMAOWNER@qa
SQL> exec dbms_stats.import_schema_stats('SCHEMAOWNER','STATTAB')
PL/SQL procedure successfully completed.

Vista Upgrade Advisor
This tool can help determine if legacy equipment will support Windows Vista.
I ran the tools on a laptop purchased this year, and the tool says I would need a TV tuner card to run the home premium version of Vista.
"TV Tuner card
Make sure you have an approved TV tuner card No compatible TV tuner was detected. Upgrade Advisor did not detect a TV tuner card in your current system. To watch TV on your computer, you need an approved USB-based TV tuner or TV tuner card. Contact your computer manufacturer for more information."
