TAATOOL Commands for copying Data Queues:

To get the data from one data queue and to get it populated to another data queue, there are some TAATOOL commands available that helps in achieving it. The following steps needs to be followed.

1. CVTDTAQ command copies the data queue data to the specified file. The Convert Data Queue command converts the entries from a keyed or non-keyed TYPE (*STD) data queue to an outfile named DTAQP. One record is written for each entry. The size of the entry field in the outfile is limited to 9,000 bytes. Data is truncated if it exceeds this amount.

The model file is TAADTQMP with a format name of DTAQR.

Run CVTDTAQ command by specifying the data queue name from which the data needs to be copied. Specify a file name to which the data needs to be populated.

2. CPYBCKDTAQ command copies the data from the file to the specified data queue. The Copy Back Data Queue command is intended for refreshing a data queue or duplicating the entries to a different data queue. You must first convert the entries in the data queue to the DTAQP file with the TAA CVTDTAQ command.

CPYBCKDTAQ then reads the data from the DTAQP file and uses the QSNDDTAQ API to send the entries to a named data queue. Both keyed and non-keyed data queues are supported.

Run CPYBCKDTAQ command by specifying the file that contains data and the data queue name to which the data needs to be populated.
