Open Information (TA_OPENINFO)

Description

Information needed to open a particular instance of a particular resource manager, or an indication that such information is not required for this group.

Valid Values

A string of 0 to 256 characters, consisting, if not empty, of four substrings, separated by colons, of the format:

rm_name:fsconfig:dbname:open_mode

These subfields are described in the following table.

Substring

Description

rm_name

TUXEDO/D for BEA Tuxedo System/D databases.
TUXEDO/SQL for BEA Tuxedo System/SQL databases.
TUXEDO/QM for BEA Tuxedo /Q databases.

fsconfig

An environment variable that contains the pathname of the database.

dbname

The name of the database.

open_mode

One of readonly or readwrite.


 

Note: The /D and /SQL databases are only used by the sample applications provided with BEA Tuxedo (for example, bankapp) and are not supported for use with the application code.

The default is no entry, that is, the null string.

On a Windows 2000 machine, semicolons are used instead of the colons after fsconfig and dbname.

The Open Information format depends on the requirements of the resource manager vendor. The string required by the vendor must be prefixed by rm_name, which is the published name of the vendor's transaction (XA) interface, followed immediately by a colon.

This field is ignored if you have not specified a name in the TMS Name (TA_TMSNAME) or if you have specified it as TMS. If you have specified a value for the TMS name but you have not done so for the Open Information field, it means that a resource manager exists for this group but does not require any information for executing an open operation.

BEA Tuxedo /Q databases use the following format:

TUXEDO/QM:qmconfig:qspace

Limitation

Run-time modifications to this attribute does not affect active servers in the group.

Example

TUXEDO/SQL:/usrq/apps/bank/bankdq:billing_db:readwrite
