After you upgrade and install Replication Servers and user databases in your replication system to a new version level, you can set the system version to match the earliest software version.
The system version is the lowest version of Replication Server allowed in the system. For example, if your replication system version is 1151, you cannot use or install a Replication Server that is earlier than version 11.5.1.
When all Replication Servers in the replication system are at version 15.2 or later, follow these steps to set the system version to 15.2:
Log in to the ID Server.
Execute:
sysadmin system_version, 1520
Note these restrictions for the system version:
If the system version is lower than 1102, new features that were introduced in later versions, including features of version 15.2, are not available. For this reason, Sybase recommends that you set the system version to 1102 or higher.
When you upgrade all Replication Servers to at least version 11.0.2, you can set the system version to at least 1102.
Once the system version is set to 1102, the availability of new features is determined by the site version setting. Thus it is not necessary to set the system version higher than 1102.
Table 3-1 illustrates the relationship between the software version number and the system version number. Note especially the ability to use the full capabilities of version 15.2 when the system version is at 1102.
Replication Server software version |
System version 1102 and higher |
|---|---|
15.2 |
Full capability when site version is set to 1520 |
15.1 |
Full capability when site version is set to 1510 |
15.0/15.0.1 |
Full capability when site version is set to 1500 |
12.6 |
Full capability when site version is set to 1260 |
12.5 |
Full capability when site version is set to 1250 |
12.1 |
Full capability when site version is set to 1210 |
12.0 |
Full capability when site version is set to 1200 |
11.5 |
Full capability when site version is set to 1150 |
11.0.2/11.0.3 |
Full capability |
New features of version 15.2 are available only when the system version is at least 1102 and the site version is set to 1520.
If a software version is supported with full capability at a given system version, you can install new Replication Servers of that software version. See “Setting the Replication Server site version” for more information.
For more information about new features, see Replication Server 15.2 New Features Guide and the release bulletin for Replication Server version 15.2.
As Table 3-1 shows, if you are upgrading from Replication Server version 11.0.2 or 11.0.3, and the system version is already set to 1102 or 1103, you do not need to set the system version to begin using new features in 15.2.
You must set the site version for Replication Servers that require it, and to upgrade routes. Information needed for the new features cannot be propagated to other sites until the corresponding routes are upgraded. See “Setting the Replication Server site version” and “Upgrading routes” for details.
