Issue/Introduction

Question: 

After I upgraded from CA Datacom Versoin 14.0 to 15.0, the Multi-user (MUF) startup now shows DB00914I messages. What does DB00914I mean and is there any impact or concern?

Answer:

There is no impact or concern. Message DB00914I is new to Datacom Version 15.0 is strictly informational. 

Additional Information:

Refer to the CA Datacom® Messages guide which defines DB00914I as follows:

DB00914I  CXX UPGRADE BASE dbid FORMAT TO 3 

Reason: 

The database number that the ‘dbid’ variable provided has been opened by CA Datacom Version 15.0 and was in a database FORMAT of 0-1-2. However, it was converted to FORMAT 3 as required for Version 15. This message occurs once per database that Version 15.0 opens. If the CXX is accessed later by a CA Datacom Version 14.0 code line, it issues the same message number but it notes ‘FORMAT TO 2’ because Version 14.0 does not support FORMAT 3 and therefore alters the format to its liking. 

Because the CXX in Version 15.0 remains in the same level and release as the CXX in Version 14.0, both code lines can interchangeably access and use the CXX. This is a Version 15 feature with a companion solution to Version 14. By allowing the CXX release to remain at 14.0 and both code Versions adapting to this common database, it allows an upgrade from 14.0 to 15.0 with no outage to change the CXX release and also no outage if needing to downgrade from 15.0 to 14.0. 

The ‘dbid’ is the database ID (number) that is being opened and having changes made to its format. 

Action: 

None. This message is for information only. However, if you see it and do not expect to see this message and it occurs, Version 14.0 code has opened the database after it was last opened by the Version 15.0 code.
