Document Type | Troubleshooting

Category | Backup/Recovery

Applicable Product Version | 6FS07

Document Number | TBATS005

 

Issue

During tbimport execution, the error JDBC-90603: Invalid operation: disconnected from the server occurs, causing the tbimport process to terminate abnormally.
 
 
 

Cause

The main connection process of tbimport waits idle until the data (row) transfer is complete.
If the row transfer operation takes longer than the time set in the ACTIVE_SESSION_TIMEOUT parameter, the main connection is forcibly disconnected by the server.
 
 

Solutions

Apply the following patches to resolve the issue.
  • FS07_CS_224949a_expimp
  • FS07_224949b
 
Caution
Apply the patch through technical support provided by Tmax Tibero.
Note
Temporary Workaround
  1. Change active_session_timeout to 0 and then perform the import.
  2. Replace the $TB_HOME/client/lib/jar/expimp.jar file with the patched expimp.jar binary.
    โ€ป It is recommended to back up the existing expimp.jar file.
