Cygwin

• a collection of tools which provide a Linux look and feel environment for Windows.
• a DLL (cygwin1.dll) which acts as a Linux API layer providing substantial Linux API functionality.

It is not:

• a way to run native Linux apps on Windows. You must rebuild your application from source if you want it to run on Windows.
• a way to magically make native Windows apps aware of UNIX® functionality like signals, ptys, etc. Again, you need to build your apps from source if you want to take advantage of Cygwin functionality.

List of file types and names used by Oracle

The following is a list of file types and names used by Oracle.

sid.DBS.xxx.DBF

Database files such as sid.DBS.CONTROL.DBF, sid.DBS.DATABASE1.DBF, or sid.DBS.LOG1.DBF contain the entire Oracle database including data dictionary, user tables, log files, and so on.

sid.DBS.INIT.ORA

Parameter file used when instance is started.

sid.P.ORAENV

Environment file containing user environment. Always to be run before start of an instance or an application: /DO sid.P.ORAENV.

Temporary ENTER-PROCEDURE file for starting background processes (using $ORAC1020.DEMO.P.ENTER).

S.OUT.tsn.YYYY-MM-DD.hhmmss

Temporary files of background processes containing run-time information. After a task is successfully completed, these files are removed. These files can help diagnosis.

L.sid.xxxx.SYSOUT.tsn

Run-time listing documenting the start of a background process. When process finishes orderly listings are removed, except the SDF-P variable BJGOUT is set to KEEP in sid.P.ORAENV for diagnosis purposes. xxxx corresponds with the identifier of Oracle background jobs.

Oracle Net Services LOG files

All errors encountered in Oracle network products are appended to a log file. The default directory path on BS2000/OSD is network.log. For more information about Oracle Net Services log files, refer to Oracle Database Net Services Administrator's Guide .

ALERT.sid.LOG

This file lists the log of significant events and errors of the database. If this file exits, the same file is used, else a new file is created. This file is valuable for diagnosis, and should not be removed.

T.sid.INSTALL.E.SUPER

To be removed after successful installation.

T.sid.INSTALL.E.SUPER.72

To be removed after successful installation.

L.sid.xxx.LOG

To be removed after successful installation, for example, L.sid.CATALOG.LOG.

ORAXALOG.tsn-NULL-YYMMDD.TRC

This file is used to trace errors when openUTM is used with Oracle. This file is created only when an error occurs. NULL can be replaced by a db_name when specified in the open string.

OTRC.sid.tsn.program.TRC

This trace file is created for one of the following reasons:

• To be analyzed by TKPROF utility, created after switch on of SQL trace by
  alter session set sql_trace=true;
  
• To be analyzed when internal errors (example: ORA-00600) or special events occur
