Solve SharePlex startup problems

Was the user an authorized SharePlex user?

Only a member of the SharePlex administrator group (default name is spadmin) can start sp_cop. A root user that is not a member of this group can start sp_cop, but no users (including root) will be able to connect through sp_ctrl to issue commands. For more information, see Assign SharePlex users to security groups.

Is this a cluster environment?

In order for the SharePlex processes to issue name lookups and migrate properly in a clustered environment (where a package name supersedes the local system name), the SP_SYS_HOST_NAME parameter must be set to the correct package name. In addition, the host name set by this parameter must be the same on all members of the cluster so that the name can bind to a socket and the /etc/hosts file or nameserver can correctly map the parameter’s value to the correct IP address.

The sp_cop program should only be started through the cluster management software.

Was the filesystem mounted as nosuid?

On Unix and Linux systems, if the filesystem is mounted as nosuid, SharePlex must be started by the installation owner. In this case, members of the SharePlex administrator group (spadmin by default), other than the installation owner, will not be able to run SharePlex.

Solve sp_ctrl problems

Did you assign the users to the SharePlex groups?

Only one SharePlex user, the Administrator who owns the SharePlex binaries and files, is created during SharePlex installation. Other users must be assigned to the appropriate SharePlex user groups. These groups control the authorization levels for various SharePlex functions.

To issue a specific command (such as activate config or stop export), a user must have that command’s authorization level or higher. For example, a SharePlex Administrator (authorization level 1) can issue any command, but a member of the spview group can only issue status commands and a few other commands that do not directly affect the replication processes.

For more information, see Assign SharePlex users to security groups.

Solve host connection problems

If SharePlex cannot resolve a host name, try creating an alias for it using a simple alphanumeric name. Map the name to the alias in the following locations:

  • Network: The NIS and DNS servers
  • UNIX: Local /etc/hosts file
  • Windows: Local hosts file

In the hosts files, put each entry on an individual line. The following is an example, where sysA and sysB are aliases:   sysA   # source system   sysB   # target system

How to find the ORACLE_SID and ORACLE_HOME

When setting up SharePlex to work with an Oracle database, you provide the ORACLE_SID and then SharePlex gets the ORACLE_HOME from the Windows Registry or theoratab file on Unix/Linux. Both values are stored in the SharePlex environment. SharePlex uses the Oracle libraries that are in the location specified with ORACLE_HOME.

To determine the ORACLE_SID and ORACLE_HOME being used by SharePlex

Issue the orainfo command in sp_ctrl.

sp_ctrl (mysysl11:2101)> orainfo

Oracle instance #1:

Oracle SID ora12

Oracle HOME /oracle/products/12

Oracle Version 12

Oracle instance #2:

Oracle SID ora12

Oracle HOME /oracle/products/12

Oracle Version 12

To determine the default ORACLE_SID and ORACLE_HOME on Windows

View the Oracle entry in the Registry at \HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE.

To determine the default ORACLE_SID and ORACLE_HOME on UNIX and Linux

On most Unix and Linux systems the oratab file is under /etc/oratab. On Oracle Solaris systems, it is under /var/opt/oracle, but sometimes there is an oratab file in the /etc directory as well.

The entry in the file looks like the following example:


In the example, qa12 is the ORACLE_SID and /qa/oracle/ora12/app/oracle/product/12.0 is the ORACLE_HOME.
