Modifying the PostgreSQL Repository Maximum Allowed Packets

If you use backup_import for a large CAR file, and if the number of packets being saved is too great for the current packet setting of the PostgreSQL repository, the following TDV error message appears:

com.compositesw.cdms.Webapi.WebapiException: One or more resources could not be saved. Packet for query is too large ... You can change this value on the server by setting the max_allowed_packet' variable.

If you encounter this error message, you can change a TDV PostgreSQL repository setting to allow a larger number of packets to be saved to the repository.

To change the PostgreSQL repository maximum allowed packets

1.

Using a PostgreSQL admin tool, log in to the PostgreSQL client as the root user.

2.

Change maximum allowed packets:

PostgreSQL> set @@max_allowed_packet = 25165824;

3.

Verify that the setting was accepted:

PostgreSQL> show variables like '%max_allowed%'; 

+--------------------+----------+ 

| Variable_name 				-----| Value ---| 

+--------------------+----------+ 

| max_allowed_packet | 25165824 | 

+--------------------+----------+
