• TFA can now be installed as the ORACLE_HOME owner:
– Will not run a daemon
– Will not perform automatic collections
– Will not collect from remote hosts
– On-demand collections will work, but limited to local files you have read access to
• Use the JRE already available in the RDBMS home unless you have a later
version available
• Where multiple DBA users own different ORACLE_HOMEs, install TFA in
different locations as the respective users
6
./installTFALite -extractto <install_dir> -javahome <jre_home>
Where possible you should install TFA as root
This option is for the cases where that is not an option

One Command SRDCs
• For certain types of problems Oracle Support will ask you to run a Service
Request Data Collection (SRDC)
• Previously this would have involved:
– Reading many different support documents
– Collecting output from many different tasks
– Gathering lots of different diagnostics
– Packaging & uploading
• TFA can now run SRDC collections for you with a single command:
tfactl diagcollect -srdc <srdc_type>

SRDCs for ORA errors:
• ora600
• ora7445
• ora700
• ora4031
• ora4030
• ora27300
• ora27301
• ora27302
SRDC for database
performance problems:
• dbperf
9
SRDC for all other types of
internal database errors:
• internalerror
One Command SRDCs
And more coming soon…

ORA4031:
1. IPS Package
2. Patch Listing
3. AWR report
4. Memory information
5. RDA
Database Performance
1. ADDM report
2. AWR for good and problem period
3. AWR Compare Period report
4. ASH report for good and problem period
5. OS Watcher
6. IPS Package (if errors during problem
period)
7. ORAchk (performance related checks)
One Command SRDCs – Examples of What’s Collected
tfactl diagcollect –srdc ora4031 tfactl diagcollect –srdc dbperf

Manual Data Gathering vs One Command SRDC
Manual Data Gathering
1. Generate ADDM reviewing Document 1680075.1
2. Identify “good” and “problem” periods and gather AWR
reviewing Document 1903158.1
3. Generate AWR compare report (awrddrpt.sql) using “good”
and “problem” periods
4. Generate ASH report for “good” and “problem” periods
reviewing Document 1903145.1
5. Collect OSWatcher data reviewing Document 301137.1
6. Check alert.log if there are any errors during the “problem”
period
7. Find any trace files generated during the “problem” period
8. Collate and upload all the above files/outputs to SR
TFA SRDC
1. Run
2. Upload resulting zip file to SR
tfactl diagcollect –srdc dbperf

1. Enter default for event date/time and database name
2. Scans system to identify recent 10 events in the system (ORA600
example shown)
3. Once the relevant event is chosen, proceeds with diagnostic
collection
Confidential – Oracle Internal/Restricted/Highly Restricted 12
One Command SRDC
tfactl diagcollect –srdc <srdc_type>
4. All required files are
identified
5. Trimmed where
applicable
6. Package in a zip ready
to provide to support
Interactive Mode

One Command SRDC
Confidential – Oracle Internal/Restricted/Highly Restricted 13
tfactl diagcollect –srdc <srdc_type> -database <db> -for <time>
1. Parameters(date/time, DB name) are provided
in the command
2. Does not prompt for any more information
3. All required files are identified
4. Trimmed where applicable
5. Package in a zip ready to provide to support
Silent Mode

One Command SRDCs
• Full command syntax:
• Uses all standard diagcollect options where relevant to the SRDC
14
tfactl diagcollect -srdc <srdc_type> [-tag <description>] [-z <filename>]
[-last <n><h|d>| -from <time> -to <time> | -for <time> ] [–database <database>]

• TFA will use a different mechanism for discovery if bash is not available
• None bash discovery mechanism will not discover non-ADR-standard
configurations:
– i.e. If your diag directory is not in ORACLE_BASE
– However any directories that are missed by the discovery can be easily added using
the directory add command:
• If bash is available it will still be used for discovery, in which case location of
diag directory does not matter
16
tfactl directory add <dir_path>
