Troubleshooting


Problem

When trying to import an IBM® Rational® ClearCase MultiSite® packet using []multitool syncreplica -import[], the operation fails with []db_open_db_V3: RPC: Unable to receive; errno = Connection reset by peer[].

Symptom

When trying to run the command, multitool syncreplica -import, it reports the following error:

db_open_db_V3: RPC: Unable to receive; errno = Connection reset by peer
multitool: Error: Trouble communicating with VOB database: "/vobs/ezx_apps".
multitool: Error: Trouble opening VOB database: "/vobs/ezx_apps".
multitool: Error: Unable to access epoch information for vob /vobs/ezx_apps.

Additional symptoms include:

  • Attempts to change directory (cd) into the VOB root also fails with I/O Error and communication timeout error

  • multitool lsreplica reports:

    multitool lsreplica -invob /vobs/ezx_apps                              
    db_open_db_V3: RPC: Unable to receive; errno = Connection reset by peer

  • The albd_log contains the following messages:

    11/12/07 10:02:04 albd_server(3244): Server db_server(4998) exited due to signal 6
    11/12/07 10:02:03 albd_server(3244): Server db_server(4997) exited due to signal 6

  • Running dbcheck usually does not report any errors.

Cause


Possible causes for this behavior are:

  1. There is corruption in the vista files in the VOB's db directory

  2. There is a hung db_server process

  3. The issue can be related to the defect, APAR PK32214, if a key file in the VOB's database directory has exceeded 32 GB

Resolving The Problem


  • Use these steps to address vista file corruption:

    1. Unmount the VOB

    2. Rename all vista files to vista_old.taf , vista_old.tcf and vista_old.tjf

    3. Kill the vob_server process

    4. Mount the VOB

    Note: If the above steps do not help, try restarting ClearCase or restarting the actual server

  • Refer to technote 1250896 for information about the various symptoms and fix for the defect
