Seting the Database IDs

I have the feeling that a given DB ID cannot be re-used also if the database has been removed. Need clarification...

dbid -r cusdefinitions -> show DBID
dbid -d cusdefinitions -> delete DBID
setdbid -C 12002 cusdefinitions -> set DBID

Updating Database Engine

• Log in as dbsa on PACS1.
• Check Database engine :

  •      oscp -i 
         oscp -l

• Download the new Database engine version from ESA page :

  • ftp://ftp.rssd.esa.int/pub/HERSCHEL/csdt/temp/ teamCSDT : usecases

• Save license file of previous version

  •       cp  /usr/local/versant/<versant-previous>/license.xml ~

• Sometimes you may request new license file (license.xml) from tzaeschk@rssd.esa.int

• Log in as root on PACS1.
• Check disk space /usr/local is quite full already.

  •      df -h

• Change to /usr/local/versant and make a directory to copy and extract the tar file.

  •      cd /usr/local/versant
         mkdir 7.0.1.1
         cd 7.0.1.1
         tar -zxvf vod7011_rhel.tar
         ./install.bin

• Just to be sure check again the system setup and restart the xinetd :

  •      oscp -i
         oscp -l
         /etc/rc.d/xinetd restart

• Install license file of previous version or requested one

  •       cp  license.xml /usr/local/versant/<versant-previous> 

• Modify psetup scipt on PACS1 : account pcss

  •       emacs /home2/pcss/psetup

    For example :

        # Can use /etc/.osc... instead of these 4 variables
        setenv VERSANT_ROOT      /usr/local/versant/7.0.1
        setenv VERSANT_DB        /dbOper/versant
        setenv VERSANT_DBID      /dbOper/versant
        setenv VERSANT_DBID_NODE pacs1 
    
        set path=( /usr/local/versant/7.0.1/bin $path )
        set LIB_DIR=/usr/local/versant/7.0.1/lib
    
        setenv LD_LIBRARY_PATH /usr/local/versant/7.0.1/lib:${LD_LIBRARY_PATH}
    
        setenv THREADS_FLAG native

Schema evolution

• Download and install PCSS containing the new Schema.
• Check LD_LIBRARY_PATH (need to point into newest database engine directory
  • non proper settings can lead to unfinished evolution which destroy the database !! e.g. /usr/local/versant/7.0.1

         setenv LD_LIBRARY_PATH /usr/local/versant/7.0.1/lib  

  • !!! The PCSS libjvi7.0.1.so caused problems in the past. You should set it to the proper VERSANT one ONLY !!!

• Check whether actualVersant engine match the reference platform engine : ftp://ftp.rssd.esa.int/pub/HERSCHEL/csdt/releases/doc/refPlatformVersion

  •        oscp -l

• Send out Schema evolution warning.
• Make sure that Databases are not used :

  •      dbtool -trans -info <DBName>

• Make a backup of the database :

  •      vbackup -dev <DBName>.vbck -backup <DBName>

• Set Databases to single user mode :

  •      dbinfo -1 <DBName>

• Perform schema evolution as described in the Database Administration Manual (HSCDT/TN044) :

  •      schema_evolver <DBName>

• Set the Database back to multi user mode :

  •      dbinfo -m <DBName>

• Test from an arbitrary account
  • set in .pcss/props the Database to the schema evolved one
  • start cusgui
• Send message to user.

Traps and Tricks

Replication aware Datbase or not

Sometimes you get an error that the Database is Replication aware or not and does not match to your access

You have two options :

• set the property :

  •       hcss.store.factory = herschel.versant.store.ReplStoreFactoryImpl

• Remove the replication mechansim from the Database :

  •       db_admin -u <DBName>

Hot Spot error for remote access

When a remote user (like Diego) start cusgui and he/she gets a java hotspot whaever error it might be caused by the user access rights !

A strange error for such a problem. Locally access you get a proper error message.

Do :

  dbuser -add -P <DBName>

Check whether there are open transactions

   dbtool -trans -info <DBName>
