DB2 VDB Provision Fails When Using Staging Push and dSource is Using Archive Location in Unmounted Location (KBA9120)




KBA# 9120



During VDB provisioning from a dSource configured with the DB2 staging push methodology the VDB job fails with this error:

db2 => rollforward db VUSCFI query status
       SQL1035N  The operation failed because the specified database cannot be connected to in the mode requested.  SQLSTATE=57019
db2 =>
Fail Message Desc               Failed to execute rollforward command on database VUSCFI

The issue is related to a missing step in preparing the dSource for provisioning.


  • Delphix Engine and higher.
  • Db2 plugin 4.1.0 and higher.

The issue can be identified and resolved by inspecting the database configuration of the dSource.  If the dSource staging database is kept consistent with backups and logs, the dSource configuration needs to set the archive log location to the mounted directory of the dSource staging database.

After the dSource is ingested check the database configuration for the archive log location with the following command:

db2 get db cfg for <dSource Staging database name> | grep -i LOGARCHMETH1

If the value returned is a non-Delphix mounted drive:

First log archive method                 (LOGARCHMETH1) = DISK:/Some_Local_Drive_or_Non-Delphix_mounted/

Change it to a location on the mounted drive using the following Db2 command:

db2 update db cfg for <dSource Staging database name> using LOGARCHMETH1 “DISK:/delphix/db2_plugin/DB2/mnts/db2inst/DB2STG/db2inst/DB2STG/archlogs/“

Using the following values where:

  • Db2 plugin location is /delphix/db2_plugin
  • db2inst is the Db2 instance name 
  • DB2STG is the staging database name
  • archlogs is the name for the directory which must be manually created after that initial ingestion
    • The instance user must be allowed to access this directory for reading

Then, check the result by checking the output from the following command:

db2 get db cfg for DB2STG | grep -i LOGARCHMETH1


First log archive method                 (LOGARCHMETH1) = DISK:/delphix/db2_plugin/DB2/mnts/db2inst/DB2STG/db2inst/DB2STG/archlogs/


You can check the db2diag.log, usually found in the Db2 instance user home under sqllib/db2dump.

  • You can check on your instance for location if not in the default:
    db2 get dbm cfg |grep -i diagpath
    Diagnostic data directory path               (DIAGPATH) = /home/auto1112/sqllib/db2dump/
    Current member resolved DIAGPATH                        = /home/auto1112/sqllib/db2dump/
    Alternate diagnostic data directory path (ALT_DIAGPATH) =
    Current member resolved ALT_DIAGPATH                    =
