Unable to Create a Temporary OPSLOG: Allocation Error 218

Products

• OPS/MVS Event Management & Automation

Issue/Introduction

When attempting to create a temporary OPSLOG using OPSVIEW panel 4.13, the operation fails with the following error:

Allocation return code 218 (X'0218')

Cause

The error code 218 (X'0218') during dynamic allocation indicates that the dataset name specified is already allocated or in use.

In the context of OPSLOG creation, this typically happens if:

• The dataset name is already cataloged.
• The dataset is currently allocated to the OPSMAIN address space.
• The dataset name is associated with another (potentially inactive) OPSLOG definition.

Resolution

To resolve this issue, ensure the dataset name used for the temporary OPSLOG is unique and not currently in use by the system.

Step 1: Verify Existing Definitions

1. Go to OPSVIEW panel 4.13.
2. Review the list of defined OPSLOGs.
3. Check if the intended dataset name is already associated with an existing entry, even if it is marked as inactive.

Step 2: Use a Unique Dataset Name

Specify a completely new and unique dataset name that is not currently cataloged or allocated to any address space.

Step 3: Alternative Allocation (Optional)

If you continue to face issues using the panel, you can pre-allocate the OPSLOG dataset using a REXX script or the DEVDIF sample member from the CCLXCNTL library. Once pre-allocated, you can then define it within panel 4.13.

Steps to be followed - 

The sample DEFDIV allocates both the SYSCHK1 and the OPSLOG. Please, create a version of this member to allocate only the temporary OPSLOG dataset. For a BROWSEMAX of 1,000,000 you need to allocate a dataset with 1,200 cylinders. 

The purpose of this approach is to get more information about a possible dynamic allocation error you are getting when trying to allocate the dataset using the panel.

After you allocate the dataset just define it using the panel 4.13.
