Configuration Scripts

Description

SharePlex provides the following scripts to automate the building of a configuration file to specify Oracle source objects.

  • config.sql: configure all tables and optionally all sequences in the database.
  • build_config.sql: configure multiple or all tables in a schema

Supported databases

Oracle

Use config.sql

The config.sql script enables you to build a configuration that lists all of the tables, and optionally all of the sequences, in all of the schemas of a database. This script saves time when establishing a high-availability replication strategy or other scenario where you want the entire database to be replicated to an identical secondary database.

Conditions for using config.sql

  • Source and target table names must be the same.

  • The script does not configure objects in the SYS, SYSTEM, and SharePlex schemas. These schemas cannot be replicated since they are system and/or instance-specific.
  • The script does not support partitioned replication. You can use the copy config command to copy the configuration file that the script builds, then use the edit config command to add entries for tables that use partitioned replication. Activate the new configuration file, not the original one.
  • You can use the edit config command to make any other changes as needed after the configuration is built.

To run config.sql

  1. Change directories to the config sub-directory of the SharePlex variable-data directory. The config.sql script puts configurations in the current working directory, and SharePlex configurations must reside in the config sub-directory.

    cd /vardir/config

  2. Log onto SQL*Plus as SYSTEM.

  3. Run config.sql using the full path from the util sub-directory of the SharePlex product directory.

    @ /proddir/util/config.sql

Refer to the following table when following the prompts.

Prompt What to enter
Target machine The name of the target machine, for example SystemB.
Source database SID The ORACLE_SID of the source (primary) Oracle instance, for example oraA. Do not include the o. keyword. The ORACLE_SID is case-sensitive.
Target database SID The ORACLE_SID of the target (destination) Oracle instance, for example oraB. Do not include the o. keyword. The ORACLE_SID is case-sensitive.
Replicate sequences Enter y to replicate sequences or n not to replicate sequences.
SharePlex oracle username The name of the SharePlex user in the source database. This entry prevents the SharePlex schema from being replicated, which would cause replication problems. If a valid name is not provided, the script fails.

Note: The name assigned by SharePlex to the configuration is config.file. If you run the script again to create another configuration file, it overwrites the first file. To preserve the original file, rename it before you create the second one.

Next steps:

  • If any tables or owners are case-sensitive, open the configuration file with the edit config command in sp_ctrl, then use the text editor to enclose case-sensitive table and owner names within double-quote marks, for example “scott”.“emp”. The script does not add the quote marks required by Oracle to enforce case-sensitivity.

    sp_ctrl> edit config filename

  • To ensure that the configuration is in the correct location, issue the list config command. If the name of the configuration is not shown, it was created in the wrong directory. Find the file and move it to the config sub-directory of the variable-data directory.

    sp_ctrl> list config

Use build_config.sql

The build_config.sql script enables you to build a configuration that contains multiple (or all) tables in a schema. It is an interactive script that prompts for each component of the configuration step by step. Instead of entering the information for each object and the routing individually, you can use a wildcard to select certain tables at once, or you can select all of the tables in the schema.

Conditions for using build_config.sql
  • Source and target table names must be the same.
  • The script does not support sequences. Before you activate the configuration that the script builds, you can use the edit config command in sp_ctrl to add entries for sequences.
  • The script does not support partitioned replication. You can use the copy config command to copy the configuration that the script builds, then use the edit config command to add entries for the tables that use partitioned replication. Activate the new configuration, not the original.
  • The script does not configure objects in the SYS, SYSTEM, and SharePlex schemas. These schemas cannot be replicated since they are system and/or instance-specific.
  • You can run build_config.sql for different schemas, then combine those configurations into one configuration by using a text editor. Make certain to eliminate all but one Datasource:o.SID line, which is the first non-commented line of the file. Do not move the file out of the config sub-directory.
  • You can use the edit config command to make any other changes as needed after the configuration is built.

To run build_config.sql

  1. Change directories to the config sub-directory of the SharePlex variable-data directory. The build_config.sql script puts configurations in the current working directory, and SharePlex configurations must reside in the config sub-directory.

    cd /vardir/config

  2. Log onto SQL*Plus as SYSTEM.

  3. Run build_config.sql using the full path from the util sub-directory of the SharePlex product directory.

    @ /proddir/util/build_config.sql

Refer to the following table when following the prompts.

Prompt What to enter
Target machine The name of the target machine, for example SystemB.
Source database SID The ORACLE_SID of the source (primary) Oracle instance, for example oraA. Do not include the o. keyword. The ORACLE_SID is case-sensitive.
Target database SID The ORACLE_SID of the target (destination) Oracle instance, for example oraB. Do not include the o. keyword. The ORACLE_SID is case-sensitive.
Owner of the source database tables The owner of the source tables.
Owner of the target database tables The owner of the target tables.
Table name to include (blank for all)

Do one of the following:

  • Press Enter to accept the default, which selects all tables that belong to the source owner.
  • Enter a wildcard (%) character and a string to select certain tables, for example %e_salary%.
  • Enter an individual table name.
Name of the output file to create A name for the configuration. The script gives the file a .lst suffix, for example Scott_config.lst.

Next steps:

  • If any tables or owners are case-sensitive, open the configuration with the edit config command in sp_ctrl, then use the text editor to enclose case-sensitive table and owner names within double-quote marks, for example “scott”.“emp”. The script does not add the quote marks required by Oracle to enforce case-sensitivity.

    sp_ctrl> edit config filename

  • To ensure that the configuration is in the correct location, issue the list config command. If the name of the configuration is not shown, it was created in the wrong directory. Find the file and move it to the config sub-directory of the variable-data directory.

    sp_ctrl> list config

cleanup.sql

Description

Use the cleanup.sql script to truncate all of the SharePlex internal tables.

Note: The cleanup.sql script does not remove the SharePlex Oracle user, password, or demonstration objects from the SharePlex tables.

The cleanup.sql script preserves the replication data in the SharePlex variable-data directory. Other utilities provide related options:

  • To clean out the variable-data directory without truncating the SharePlex tables, see clean_vardir.sh.
  • To clean out the variable-data directory and truncate the SharePlex tables, see ora_cleansp. This utility completely restore SharePlex to an initial state.

Contact Quest Technical Support before running cleanup.sql for the first time. Unless a procedure in the SharePlex documentation requires running clean_vardir.sh, this utility rarely is appropriate in a production environment. It deactivates the configuration, and using it improperly can result in replication problems and the need to resynchronize the data. Usually, there is another alternative.

Supported Databases

Oracle on Unix and Windows

Run cleanup.sql

  1. Log into Oracle as the SharePlex database user. The SharePlex tables belong to that user. On Unix and Linux, If you are running multiple instances of sp_cop with multiple variable-data directories, there is a SharePlex Oracle user for each one. Make certain to run this script as the correct one.

  2. (Unix and Linux) Set the SP_SYS_VARDIR environment variable to point to the SharePlex variable-data directory.

    ksh shell:

    export SP_SYS_VARDIR=/full_path_of_variable-data_directory

    csh shell:

    setenv SP_SYS_VARDIR=/full_path_of_variable-data_directory

  3. Run cleanup.sql as a SharePlex Administrator. The script is in the bin sub-directory of the SharePlex product directory. Use the following syntax, where Oracle_version is one of the SharePlex-supported Oracle versions.

    SQL> @proddir/bin/cleanup.sql

clean_vardir.sh

Description

Use the clean_vardir.sh script to clean out the variable-data directory to restore it to an initial state.

  • The clean_vardir.sh script preserves the contents of the SharePlex internal tables.
    • To truncate the SharePlex tables, without cleaning out the variable-data directory, see cleanup.sql.
    • To clean out the variable-data directory and truncate the SharePlex tables, see the appropriate database_cleansp utility, where database is the type of database. This utility completely restore SharePlex to an initial state.

    Important! Contact Quest Technical Support before running clean_vardir.sh for the first time. Unless a procedure in the SharePlex documentation requires running clean_vardir.sh, this utility rarely is appropriate in a production environment. It deactivates the configuration, and using it improperly can result in replication problems and the need to resynchronize the data. Usually, there is another alternative.

    What this utility does

    The clean_vardir.sh script removes the following:

    • the queue files in the rim sub-directory.
    • the log files in the log sub-directory. The Event log retains one entry reflecting the clean_vardir.sh procedure.
    • the contents of the statusdb file in the data sub-directory.
    • the contents of the dump and state sub-directories.

    The clean_vardir.sh script preserves user-created files such as configuration files, conflict-resolution files, hint files, the paramdb, and the oramsglist file.

    The clean_vardir.sh script deactivates configurations. To start replication after running clean_vardir.sh, you must activate a configuration.

    Supported databases

    Oracle on Unix and Linux

    Shell requirement

    To use this utility, the Korn (ksh) shell must be installed on the system. The utility calls this shell during processing.

    Run clean_vardir.sh

    Run this script on Unix and Linux systems only.

    1. Shut down sp_cop.

    2. Set the SP_SYS_VARDIR environment variable to point to the SharePlex variable-data directory. If SP_SYS_VARDIR is not set, clean_vardir.sh affects the directory listed in the proddir/data/default.yaml file, where the proddir is the bin sub-directory of the SharePlex product directory.

      ksh shell:

      export SP_SYS_VARDIR=/full_path_of_variable-data_directory

      csh shell:

      setenv SP_SYS_VARDIR=/full_path_of_variable-data_directory

    3. Run clean_vardir.sh as a SharePlex Administrator. The script is in the bin sub-directory of the SharePlex product directory. Use the following syntax, where Oracle_version is one of the SharePlex-supported Oracle versions.

      proddir/bin/clean_vardir.sh Oracle_version

    When the script is finished running, you are returned to the command prompt.

    Note: If the script generates an error message stating that it cannot remove the save_SharePlex_version directory, you can remove that directory manually.
